What does dog saliva consist of?

Dog saliva is a complex and multifunctional biological fluid that performs a number of important functions in the animal’s body. It not only helps maintain oral hygiene by cleaning the mucous membrane and teeth from food debris, but also has protective properties, preventing the development of caries. It contains various components that provide antimicrobial and anti-inflammatory effects:

Immunoglobulins are special protein molecules that play a key role in the functioning of the immune system. They act as antibodies, binding to viruses and bacteria, and help the body fight infections.

Lysozyme is an enzyme with a powerful antibacterial effect. It destroys the cell walls of bacteria, leading to their death, and also has anti-inflammatory properties, promoting rapid healing of damaged tissues.

Lactoperoxidase is another enzyme that activates oxidative processes in saliva, which leads to a decrease in the number of pathogenic microorganisms. This enzyme creates unfavorable conditions for the reproduction of bacteria and thereby reduces the risk of infection.

Mucins are glycoproteins that play an important role in the formation of mucus. Mucus, in turn, helps to glue bacteria together and remove them from the oral cavity, which prevents them from penetrating the body and developing infections.

Despite the presence of antiseptic properties, dog saliva is not a sterile liquid. It is indeed able to suppress the growth and activity of some types of bacteria, such as streptococci and E. coli. However, other microorganisms, such as staphylococci, Pseudomonas aeruginosa and capnocytophages, are resistant to enzymes in dog saliva and can successfully reproduce in the animal’s oral cavity. These bacteria can be dangerous for both humans and other animals. Although they often do not cause visible symptoms in dogs themselves, their presence in saliva can pose a serious threat when in contact with damaged tissue.

The diversity of microbes living in dog saliva is explained by a number of factors. An important role is played by the habit of animals to frequently lick their fur and skin, which leads to the transfer of various microorganisms from the environment into the oral cavity. In addition, the lack of regular and thorough oral hygiene contributes to the accumulation of bacteria, which creates favorable conditions for their reproduction. This explains why dogs quite often have problems with teeth and gums, such as caries and inflammatory processes.

Why should you not let your dog lick wounds?

There are several reasons why it is not recommended to let your dog lick wounds:

• Risk of infection with dangerous bacteria. Any wound is a violation of the integrity of the skin or mucous membrane, which makes it vulnerable to the penetration of pathogenic microorganisms. Even through small damage to the skin, bacteria can enter the body and spread quickly, causing infectious diseases. When a dog licks a wound, dangerous microbes that live in its oral cavity can get there along with the antibacterial components of its saliva. These microbes can include bacteria, viruses, fungi, and even multicellular parasites that can cause serious diseases.
• Transfer of microbes from the oral cavity. Dog saliva contains a large number of different microorganisms. Some of them may be safe for the animal itself, but pose a threat to humans if they get into the wound. For example, staphylococcus, which is usually present in the dog’s oral cavity, when it gets into the wound, can begin to actively multiply and cause suppuration, which is life-threatening. This is especially true for people with weakened immunity, for whom any infection can lead to serious consequences.
• Slowing down the healing process. Dogs have a rough tongue, which can further injure the tissues at the wound site, delaying their recovery. Repeated mechanical damage caused by frequent licking can lead to chronic inflammation and slow healing. That is why after surgeries or serious injuries, veterinarians recommend using special protective collars that prevent the dog from accessing the inflamed areas.
• Ineffectiveness of saliva in treating serious injuries. In some cases, microbes can penetrate deep into the tissue and begin to spread beyond the original wound. In such situations, local treatment, including exposure to saliva, is insufficient to prevent the development of infection. In these cases, more serious measures are required, such as the use of antiseptics and antibiotics, to prevent complications.

Dog owners can always disinfect the wound in a safer way. One of the most effective methods is rinsing the wound with clean water or an antiseptic solution, which helps remove dirt and microbes from its surface. After this, the wound can be covered with a bandage or a sterile dressing to prevent further contamination. However, if the wound is severe or does not heal well, it is recommended to contact a veterinarian for professional help.

Dangers of Dog Saliva for Humans

Although dog saliva may not pose a serious threat to human health under certain conditions, there are still risks. If there are no breaks in the skin and you wash your hands and face thoroughly after contact with the animal, the risk of infection is minimal. However, even with proper hygiene, the risk of infection remains, especially if saliva comes into contact with mucous membranes of the face, such as the eyes, nose, or mouth.

When a dog licks the area of ​​​​the eyes, nose, or mouth, there is a risk of transmitting serious diseases such as rabies. Rabies is a viral disease that is transmitted through the saliva of an infected animal and is almost always fatal after the first symptoms appear. Even if a dog looks healthy but has not been vaccinated against rabies, it may be a carrier of the virus. Therefore, it is extremely important to avoid close contact with unfamiliar and stray animals, especially if they try to lick your face or hands.

Dog saliva can be especially dangerous if there are any injuries to the human skin, even minor ones. Dangerous microbes can get into such wounds, which is especially dangerous for people with weakened or undeveloped immunity, such as small children, the elderly, and people with immunodeficiencies. Even if the dog is domestic and vaccinated, its saliva may contain bacteria that are dangerous to humans, such as pasteurella, capnocytophaga, bordetella, and other microorganisms that can cause serious diseases.

In nature, saliva is the only available means for animals to clean open skin lesions. However, despite this, saliva may not only not help, but also aggravate the situation, slowing down the healing process and increasing the risk of infection. Therefore, if a dog is injured, a more reliable method would be to wash the wound with clean water, treat it with an antiseptic, and apply a sterile bandage. These measures will provide better protection against infection than using saliva.

Even if there are no visible wounds on the body, contact with dog saliva is not completely safe. Germs from the animal’s mouth can get onto the mucous membrane or into microscopic damage to human skin, which can lead to the development of an infection.

To minimize the risks, you should adhere to the following rules:

• Do not allow unfamiliar and street dogs to lick you, especially on the street. Protect your face and damaged areas of the skin from contact with the dog’s tongue.
• Regularly monitor the health of your pet – get vaccinations on time, do not miss scheduled visits to the veterinarian, and also pay attention to the dog’s oral hygiene, regularly brushing its teeth.

These measures will help reduce the risk of infection and maintain the health of both the person and his pet.

What you need to know about hygiene: 7 unexpected tips

Since childhood, we are taught basic hygiene skills: leave outdoor shoes at the entrance, wash your hands after using the toilet and before eating. These simple rules help keep your home clean and prevent the spread of infections.

However, there are many other aspects of hygiene that are not so obvious and may raise questions. For example, how to properly care for your ears? How often should you change your socks and underwear? Is it really necessary to make your bed every morning? These and other questions regarding everyday hygiene deserve attention, because the right answers to them can significantly affect our health and well-being. In this article, we have collected recommendations from experts – doctors and scientists who will help you understand these important issues.

TIP #1: Avoid using cotton swabs and ear curettes

The skin lining the ear canal is a natural barrier that protects the ear from dust, dirt and germs. This barrier is very important for maintaining healthy ears. However, like any other part of our body, the skin in the ears is constantly being renewed. Over time, the surface skin cells die and need to be removed from the body to prevent the accumulation of dead particles.

In order for dead cells to be able to leave the ear naturally, the ear canal is equipped with sebaceous and sulfur glands that secrete a special secretion. This secretion, when mixed with dead cells, forms earwax. Although earwax may seem untidy, it plays an important role in protecting the ear by creating a barrier that does not allow dust and germs to penetrate inside.

There is often a desire to remove wax with cotton swabs or other tools to keep the ears clean. However, this can be dangerous and does more harm than good.

What to do

Ears are an organ that has the ability to clean themselves. When we chew food or talk, jaw movements naturally move wax, along with dirt particles, to the outer part of the ear. That is why there is no need to clean the inside of the ear canal regularly. It is enough to gently wipe the auricle with a soft damp cloth or towel from time to time to remove visible traces of wax.

Using cotton swabs, ear curettes or tampons can lead to a significant portion of the wax being pressed deeper into the ear canal, which, in turn, can provoke the formation of a wax plug. In addition, a stick or curette can damage the delicate skin of the ear canal or even the eardrum, which will lead to serious hearing problems.

What to consider

In most cases, according to doctors, ears do not need to be cleaned at all, since they cope with this task on their own. However, there are people who experience increased wax production, a narrow ear canal or a predisposition to infections. In such cases, there is a risk of earwax plugs, which can cause discomfort and hearing loss.

If you suspect that you have earwax plugs, do not rush to use cotton swabs or other improvised means. It is best to put a few drops of baby oil or hydrogen peroxide in your ear. This will help soften the earwax plug, and within 1-2 days it will naturally come out. After this, you can gently rinse your ear with warm water, avoiding sudden movements and strong pressure. It is important to dry the ear by wiping it with a soft towel to prevent water from getting into the ear canal, which can cause irritation.

If discomfort persists after these procedures, it is better to consult an otolaryngologist. A specialist will be able to safely and effectively remove the plug, as well as give recommendations for ear care, taking into account your individual characteristics.

Tip #2: Change your socks once or twice a day

Why is this important?

The skin of your feet actively secretes sweat, which is necessary to regulate body temperature and prevent overheating. Sweat contains various substances, such as lipids, proteins and hormones. Although sweat itself is almost odorless, these components become a breeding ground for bacteria living on the skin. As a result of the bacteria’s activity, volatile compounds are formed, which give sweat an unpleasant odor.

These bacteria begin to actively multiply immediately after favorable conditions are created, such as high humidity and temperature. Therefore, most people who put on clean socks in the morning already have a characteristic unpleasant odor from their feet by the evening. This happens because bacteria have time to process the components of sweat during the day, releasing metabolic products that cause the odor.

What to do

In order to avoid an unpleasant odor and reduce the risk of developing skin diseases, it is recommended to change your socks at least once a day. This simple step will help prevent bacteria from accumulating on the skin and fabric of your socks, as well as reduce the likelihood of developing fungal and bacterial infections that can affect the skin of your feet and nails.

If you are in high-temperature conditions, such as in the heat, are actively involved in sports, or suffer from excessive sweating of the feet, you should change your socks more often – twice a day. Frequent changing of socks helps keep your feet dry, which significantly slows the growth and reproduction of bacteria and fungi that love a moist environment.

How to choose socks?

It does not matter what material your socks are made of – they should be changed 1-2 times a day. However, materials can still affect the comfort and health of your feet. If you are prone to fungal infections or you often experience rubbing of the feet, choose socks made of materials that wick moisture away from the skin, such as polyester or acrylic. These materials promote rapid evaporation of moisture, which helps keep your feet dry.

People with excessive sweating of the feet are better off with socks that not only absorb moisture but also provide good ventilation. Such products help maintain a cool and dry environment for the feet, reducing the risk of excessive sweating. Usually, socks made of natural materials such as cotton or wool are used for this purpose. These fabrics allow the skin to breathe and prevent the feet from overheating, which is especially important in the warm season.

Also, do not forget that socks need to be washed after each use. Even if the socks do not look dirty, bacteria and fungi can remain on their surface, which will begin to multiply when worn again. Regularly washing socks helps prevent the accumulation of microorganisms and keeps your feet healthy.

Tip #3: Wear underwear as long as it retains its shape and comfort

Why is this important

Some sources recommend changing underwear, especially underwear, every 6 to 12 months. This advice is related to the fact that over time, the fabric can accumulate microbes that can cause various infections. This is especially true for underwear that is worn daily and is often exposed to sweat and other body secretions.

Underwear, as a rule, fits tightly to the body and creates a warm, moist environment, which is ideal for the reproduction of bacteria and fungi. Microorganisms found on the skin, mucous membranes of the genitals or getting on the fabric with feces can survive in such an environment and, under certain conditions, cause infectious diseases. For example, some types of bacteria can cause cystitis or other urogenital infections.

What to do

Despite the fact that the risk of microorganisms accumulating in underwear exists, regularly changing and washing underwear significantly reduces this danger. If a person changes underwear daily and washes it after each wear, using modern detergents, most microbes die. Modern washing powders and gels contain active ingredients such as bleach activators and antibacterial additives that effectively destroy most bacteria and fungi even at low water temperatures.

Even if a small number of microorganisms survive washing, they do not pose a serious threat to health. The body’s immune system is strong enough to cope with this amount of microbes and prevent the development of infection. An important aspect is the regularity of changing underwear and thorough washing, which allows you to maintain the necessary level of hygiene and reduces the risk of disease.

Features and service life of underwear

Regular changing and washing of underwear helps to minimize the microbiological hazard, so underwear does not have a strict expiration date. If your underwear remains intact, does not lose its shape and still fits comfortably, you can continue to wear it.

However, it is important to pay attention to the condition of the fabric. If the underwear begins to lose elasticity, stretches or loses its shape, it may no longer provide the necessary support and comfort. In such cases, it is better to replace it with a new one to maintain maximum comfort and hygiene.

It is also worth considering individual preferences and feelings. If you feel that your underwear is no longer as comfortable as it used to be, or you feel discomfort, this may be a signal that it is time to update your wardrobe.

Tip #4: Shower Daily

Why It Matters?

The question of how often to shower is controversial both among experts and in popular literature. Some experts insist that daily washing is necessary to remove dirt, sweat and dead skin cells. However, there is an opinion that frequent washing can be harmful, since it washes away not only dirt, but also sebum – a natural oil that moisturizes the skin, maintains its microbiome and partially protects against ultraviolet radiation.

What to do?

Sebum plays an important role in protecting the skin, but it is also a breeding ground for bacteria that live on the surface of the skin. These bacteria process the components of sebum, and their waste products create a characteristic body odor.

Sebum is especially actively produced in young people during puberty, as well as in those who wear synthetic clothing, do physical work, or spend a lot of time in hot conditions. In such cases, it is recommended to shower every day to control body odor and maintain hygiene at the proper level.

Features and recommendations

To avoid overdrying the skin, especially in the summer, it is recommended to shower daily, using warm, but not hot water. It is better to limit the duration of the shower to 10 minutes, and to cleanse the skin, choose soft shower gels that do not contain dyes and strong fragrances. Such products gently remove excess sebum without disturbing the protective barrier of the skin.

There is no need to wash your hair every day, unless your hair tends to get dirty quickly, such as in people with oily scalps or those who play sports.

In winter, you can shower every other day, as the skin tends to get dry during this period due to cold air and heating. However, the rules remain the same: use warm water and mild detergents to avoid overdrying the skin.

Tip #5: Make your bed an hour after waking up

Why is this important?

Making your bed protects your bedding from dust and dirt. However, there is a hypothesis that damp sheets covered with a bedspread can promote the proliferation of dust mites – microscopic organisms that can cause allergies in some people. If the bed is left unmade, the sheets dry out and the number of mites may decrease.

What to do?

For people with dust allergies, simply drying the bed will not solve the problem, since the allergy can be caused not only by live mites, but also by their dead remains. To minimize the number of dust mites, it is important to maintain indoor humidity below 50%, use dust-proof covers for mattresses and pillows, wash bed linen once a week at a temperature of at least +60 °C, and regularly carry out wet cleaning.

However, making the bed some time after waking up is a good habit. It allows the bed to dry, which makes sleeping on it more comfortable and slows down the proliferation of bacteria that can cause an unpleasant odor.

Features and recommendations

Although there is no scientific consensus on whether it is necessary to make the bed every day, this habit has more pros than cons. A made bed not only keeps the room tidy, but also helps to set the tone for a productive day.

If you let your linen dry before making your bed after waking up, the benefits of this action become obvious. To do this, just do other morning chores – wash your face, have breakfast or exercise. In about an hour, the bed linen will be dry and can be neatly tucked.

Tip # 6: Use chlorine-containing cleaning products

Why it is important?

Some people avoid using chlorine-containing cleaning products at home, fearing the release of toxic chlorine, which can be harmful to health. However, the correct use of these products helps to effectively combat dirt and germs.

What to do?

The main component of most such products is sodium hypochlorite (NaClO), which, when dissolved in water, forms chlorine compounds that act as powerful oxidizers. These compounds not only bleach, but also destroy the membranes of viruses and the cell walls of bacteria, making chlorine-containing products effective in the fight against germs.

Chlorine gas is released only in a very acidic environment (pH less than 4). To avoid this, sodium hydroxide (NaOH) is added to cleaning products, which increases the pH of the solution to a safe level. Therefore, when using chlorine-containing products, it is important not to mix them with acidic products such as vinegar or citric acid to avoid the release of harmful gases.

Features and recommendations

When used according to the instructions and with a frequency of use no more than four times a week, chlorine-containing products do not pose a health risk. These products may cause mild irritation if they come into contact with the skin or eyes, but there will be no serious consequences if the affected areas are quickly washed with water.

However, people with dermatitis or asthma should avoid using such products. In people with dermatitis, chlorine-containing products can aggravate the irritation, and in asthmatics, even small amounts of volatile hypochlorous acid, which can be released during cleaning, can trigger an attack.

Tip #7: Don’t be afraid to use public washing machines and laundries

Why it’s important?

Biofilms can form inside washing machines, which are home to conditionally opportunistic bacteria, such as pseudomonas, citrobacter, and serratia. These microorganisms can cause infections in people with weakened immune systems, especially pregnant women, hospitalized patients, and the elderly.

What to do?

To date, cases of infections caused by opportunistic bacteria from washing machines have been reported only in hospitals and large healthcare facilities. There are no reports of customers of laundries or public washing machines in hotels or hostels becoming ill due to these bacteria.

However, people with weakened immune systems, including pregnant women and those taking immunosuppressants, should avoid doing their laundry in public places. When traveling, it is safer to take your clothes to large, reputable laundries or dry cleaners.

Features and recommendations

If you do not have access to a laundromat or dry cleaner, you can minimize the risk by washing in a public washing machine. Adding a product with bleach activator TAED and active oxygen agents to water allows for effective destruction of bacteria. These products work even at a temperature of +40 °C, which makes them suitable for washing colored items and linen made from natural fabrics.

What are plaques on the eyelids?

In medical terminology, plaques on the eyelids that have a yellowish tint are called xanthelasma. This word comes from the Greek word “xanthos”, which translates as “yellow plate”.

Xanthelasmas are soft or semi-hard growths that are yellowish in color and most often located on the inner corners of the upper eyelids, although they can also occur on the lower eyelids. These growths often appear symmetrically on both eyes.

Xanthelasmas are cholesterol deposits by nature. They are completely benign, do not cause pain, and do not turn into malignant tumors. However, large growths can cause discomfort and interfere with the normal functioning of the eyelids.

According to statistics, xanthelasmas occur in 1.1% of women and 0.3% of men, and can occur between the ages of 20 and 70, with a maximum incidence at the age of 40-50.

Why do eyelid xanthelasmas occur?

It is believed that xanthelasmas are formed as follows: immune system cells called macrophages, which are found in the skin, absorb excessive amounts of lipids. At some point, the fat-filled macrophages lose control of their lipid metabolism and turn into foam cells. The accumulation of these foam cells leads to the formation of growths known as xanthelasmas.

Many people with xanthelasmas do have elevated blood lipids. Lipid disorders can be primary or secondary. Primary disorders, such as hereditary hyperlipidemia, are associated with genetic diseases that lead to elevated levels of “bad” cholesterol at a young age.

Secondary disorders can occur due to excess weight, smoking, alcohol abuse, and various chronic diseases and conditions. These diseases include:

• Diabetes: A chronic disease associated with abnormal blood sugar metabolism.
• Hypertension: High blood pressure, which can contribute to the formation of fatty deposits.
• Hypothyroidism: A deficiency of thyroid hormones, which can lead to abnormal lipid metabolism.
• Primary biliary cholangitis: Inflammation and destruction of the small bile ducts in the liver.
• Sarcoidosis: An autoimmune disease that can affect many organs, including the skin.

In addition, lipid levels can be elevated by certain medications, such as corticosteroids, retinoids, immunosuppressants, estrogens, and drugs used to treat epilepsy.

However, about half of people with xanthelasma do not have significant lipid abnormalities, and the exact cause remains unknown. Xanthelasma is rare in young people and is most often associated with dyslipidemia.

How is xanthelasma diagnosed?

A doctor can diagnose xanthelasma based on the appearance of the growths. This does not require specialized diagnostic equipment. However, since xanthelasma can be a symptom of other conditions, blood tests for lipid and glucose levels are usually ordered when they are detected, and thyroid hormone levels, liver enzymes, and other indicators are sometimes checked.

How are eyelid plaques treated?

Xanthelasma is a benign growth that does not pose a health threat and does not require mandatory treatment. However, since the growths do not resolve on their own and can grow in size, as well as be a cosmetic concern, many people decide to have them removed.

There are various methods for removing xanthelasma, including:

• Chemical peels: Using concentrated trichloroacetic acid to remove the growths.
• Cryotherapy: Using liquid nitrogen to freeze and remove the growths.
• Radiofrequency ablation: A method of removing growths using radiofrequency waves.
• Laser removal: Using a laser to precisely remove xanthelasma.
• Surgical excision: Traditional surgical removal of the growths.

Once xanthelasmas are removed, there is a chance that they will recur, especially in people with high cholesterol and all four eyelids affected. With repeated removal, xanthelasmas may recur in 60% of patients.

In summary, although xanthelasmas themselves are not dangerous and are benign growths, they are formations, their presence may indicate the need to check your cholesterol levels and overall health.

While cosmetic treatment of xanthelasma, or yellowish plaques on the eyelids, is not always necessary, it is important to understand that the presence of these plaques may indicate a more serious health problem. Xanthelasma may be a symptom of dyslipidemia, a condition in which the level of lipids (fats) in the blood is abnormal, which significantly increases the risk of developing cardiovascular disease.

Dyslipidemia can be primary or secondary. Primary dyslipidemia is usually associated with hereditary factors and genetic predispositions that lead to increased levels of “bad” cholesterol in the blood. Secondary dyslipidemia can develop as a result of other factors, such as excess weight, smoking, alcohol abuse, chronic diseases including diabetes, hypertension, hypothyroidism, primary biliary cholangitis, sarcoidosis, as well as the use of certain medications.

Because dyslipidemia can affect overall cardiovascular health, it is important to manage the condition. Doctors typically recommend lifestyle changes to lower cholesterol and improve lipid profiles. These changes may include:

• Losing weight: Being overweight or obese contributes to high cholesterol, so losing weight can help improve your lipid profile.
• Changing your diet: Reducing your intake of saturated and trans fats, increasing your fiber intake, and including foods rich in omega-3 fatty acids, such as fish, can help improve your cholesterol levels.
• Physical activity: Regular exercise can improve overall cardiovascular health and help lower your “bad” cholesterol.
• Quitting smoking: Smoking significantly increases your risk of heart disease and can worsen lipid problems.

In some cases, medication may be needed in addition to lifestyle changes. Your doctor may prescribe cholesterol-lowering medications, such as statins or fibrates. Specific treatment will be determined based on the exact diagnosis, the level of dyslipidemia, and the patient’s overall health.

It is important to have regular medical checkups and follow your doctor’s recommendations to prevent cardiovascular disease and maintain overall health. Eliminating the causes that lead to the formation of xanthelasma will help improve not only your appearance, but your overall health as well.

Visit a trichologist

In 95% of cases, the cause of receding hairline is the effect of testosterone, but stress, poor diet, hormonal imbalances or defects in the immune system can also play a role.

Optimize your diet, strive for psychological balance

Important foods for healthy hair include salmon, poultry, legumes, nuts (especially cashews, pecans and almonds), eggs and dairy products. Practice physical exercise, enjoy walks in the fresh air, take a contrast shower and ensure you get enough sleep.

Visit a beauty salon

Visit a beauty salon or try various treatments that can stimulate hair growth, such as cryotherapy, ozone therapy, mesotherapy and plasma lifting. To add volume to your hair, you can use special products designed for thin hair. In addition, a short haircut with thinning can create a visual effect of hair density.

Provide opportunities for medical interventions

There are many medications available for alopecia, including a variety of creams, gels, capsules and tablets, as well as physical therapy. Consider a hair transplant procedure, this can be an effective solution, but this method is not suitable for everyone, given its cost and contraindications.

Myth: Drinking plenty of water keeps your skin hydrated

Maintaining optimal fluid balance in the body is key to overall health. However, it is important to remember that drinking excess water is not always beneficial. While drinking plenty of water throughout the day is important for healthy skin and overall well-being, going over the recommended intake will not lead to better skin.

Individual fluid requirements may vary depending on factors such as weight, climate, physical activity and lifestyle. However, there is not enough scientific evidence to support a direct link between fluid intake and skin conditions, except in extreme cases such as severe dehydration or heatstroke.

Proper water consumption plays an important role in maintaining health, including skin condition. However, while hydration is important, it is not a panacea for all skin problems. Drinking enough water helps keep your body hydrated and promotes overall skin health, but it doesn’t guarantee dramatic improvement.

Proper nutrition, regular skin care, and protection from harmful external factors are also important to achieve optimal skin health.

Myth: Dirt on the skin causes acne

No, ordinary dirt is not the only or main cause of acne. But while ordinary dirt may not directly cause acne, certain substances, such as oily foods, hair gels, greasy makeup or industrial oils, can clog skin pores, contributing to the appearance of acne.

Acne is usually associated with more complex factors, such as hormonal imbalances and a tendency for pores to become clogged with skin secretions such as keratin, which is secreted by skin cells.

The skin microbiome of people with acne may be different from that of people with healthy skin, but this is not associated with dirt. In recent years, there has been an increase in cases of acne associated with the use of smartphones. Acne appears on the side of the face to which a person is accustomed to pressing a mobile device.

This is due to a combination of factors: short-wave light from a smartphone, sweat, dirt, heat, friction and bacteria on the surface. An effective prevention is to regularly clean the screen of your smartphone.

Myth: Any exposure to the sun is bad for your skin

Every exposure to the sun undoubtedly leaves traces of photodamage on the skin, but it is important to realize that sunlight is essential for the health of our body, especially in the context of vitamin D synthesis.

This need is especially relevant for those who live in areas remote from the equator, as well as for people with dark skin types who require more time to form vitamin D when exposed to sunlight.

The anti-inflammatory properties of solar radiation are currently being actively researched, which may be useful in the treatment of certain skin diseases such as psoriasis, eczema and itchy skin.

It is important to balance the potential benefits with the risk of skin cancer, which is directly related to exposure to ultraviolet rays. It is recommended to use sunscreen and wear protective clothing, and avoid prolonged exposure to the sun between 11am and 3pm.

At least five million new cases of skin cancer are diagnosed each year in the United States. Most are associated with excess exposure to sunlight, highlighting the importance of protecting the skin from UV rays and taking preventative measures.

Myth: Vitamin E helps get rid of scars

It has long been believed that vitamin E may have beneficial effects on scars, but this claim has been extensively researched for many years. Unfortunately, experts say the arguments supporting this are not convincing. Current evidence does not show a significant beneficial effect of vitamin E on scars.

In some cases, the use of vitamin E for medicinal purposes can be harmful if the individual characteristics of the body are not taken into account. In this regard, it is recommended to look at products based on silicone gel as an alternative.

Multiple studies have shown that such products have a noticeable positive effect on the healing processes of scars and the appearance of existing scars.

Myth: Wounds heal better in air

This myth, which believes that wounds heal faster in the fresh air, has become firmly entrenched in everyday consciousness, but this is far from the truth. In fact, research shows that wounds heal more effectively in a moist environment.

The results of many studies clearly demonstrate that during the early phases of wound healing, cells migrate more efficiently in a moist environment. If there are no signs of infection or inflammation, it is recommended to apply a doctor-recommended product to the wound and cover it with a sterile dressing.

However, in the later stages of the healing process, when the wound is almost healed, the passage of fresh air can be a beneficial factor.

Myth: Daily exfoliation is essential for healthy skin

Exfoliation is a natural process in which dead skin cells are removed from the surface of the skin. This process helps maintain healthy skin, leaving it softer and smoother. However, it is not always necessary to use artificial exfoliation products, since the skin itself is able to regulate this process.

Excessive use of exfoliants can destroy the skin’s natural protective barrier and cause irritation. Therefore, it is important to maintain a balance and not overuse exfoliation products, giving the skin the opportunity to independently maintain its health.

Myth: The more expensive the creams, the longer the skin will remain young

The skin care cosmetics industry is a gigantic business. For example, in the United States alone, sales of “prestige skin care” exceeded $1.1 billion between April and June 2020.

However, no cream, despite its popularity and price, is capable of indefinitely protecting the skin from the natural aging process.

Myth 1. You can only get enough vitamin D by sunbathing

This statement has long been untrue. Nowadays, due to increased ultraviolet radiation and environmental pollution, the body’s synthesis of vitamin D may be insufficient. Factors such as skin color, time of day and geographic location, and use of sunscreens can reduce the body’s production of vitamin D. Therefore, it is important to consider these factors and, if necessary, take special supplements.

Myth 2. Without symptoms there is no deficiency

This is a myth that can have serious consequences. Even if there are no obvious symptoms, this does not mean that the level of vitamin D in the body is normal. Vitamin D deficiency can be asymptomatic, but at the same time cause various complications, such as impaired bone mineralization and decreased immunity. Regular testing and consultation with your doctor can help identify deficiency and prevent its negative consequences.

Common symptoms of vitamin D deficiency include fatigue, irritability, and frequent illness. However, these same symptoms may indicate other deficiencies, such as iron.

Myth 3. Frequent tanning is harmful to the body

Modern research shows that to stimulate the synthesis of vitamin D, it is necessary to receive too high a dose of ultraviolet radiation, which can be harmful to the skin. Moreover, the pigment that forms in the skin after tanning blocks further synthesis of vitamin D. Thus, excessive exposure to the sun does not increase the supply of vitamin D in the body.

Myth 4. Standard dosages of vitamin D are suitable for everyone

In fact, standard dosages of vitamin D will not be sufficient for everyone. Depending on age, geographic location and individual characteristics of the body, the need for vitamin D may vary. Therefore, it is important to obtain recommendations from a doctor and, if necessary, adjust the dosage.

Myth 5. Vitamin deficiency occurs in spring

With the development of international trade, access to vegetables and fruits has become year-round. Therefore, spring vitamin deficiency is not as relevant today as it used to be. However, if you feel unwell in the spring, it is important to consult a doctor and, if necessary, undergo testing for deficiencies. Taking vitamins on your own without consulting a doctor can be ineffective and even harmful.

Myth 6. Dietary supplements replace medications and a healthy diet

Dietary supplements should not replace medications and a balanced diet. They can be useful additions to a healthy lifestyle, but cannot replace a holistic approach to strengthening the body.

Myth 7. Dietary supplements can completely cover the need for nutrients

Although dietary supplements can be helpful, they are not a complete replacement for nutrition. A healthy and balanced diet remains a key element in maintaining health and vitamin balance in the body.

Myth #1: Foundation with SPF replaces sunscreen

One common myth is that foundation with SPF can completely replace sunscreen. However, to ensure the proper level of protection from UV rays, you need to apply enough sunscreen – 1/3 to 1/4 teaspoon to the face and neck. If you use the same amount of foundation, the result may not be beautiful. It’s best to wear sunscreen under your makeup or use a tinted sunscreen that matches your skin color.

Myth #2: Antibacterial soap is better than regular soap

Quite often you can hear the statement that antibacterial soap is more effective than regular soap in fighting bacteria. However, research does not confirm this fact. Moreover, antibacterial soaps containing antimicrobial ingredients can dry out the skin and disrupt its natural protective barrier. In addition, overuse of such soaps can promote the emergence of antibiotic-resistant bacteria, making it more difficult to treat certain diseases.

Myth No. 3: Tonic is an integral part of daily skin care

Previously, toner was considered an integral part of the skin care ritual, since many cleansers were alkaline, and toner helped restore the natural pH balance of the skin. However, with the advent of softer cleansing products, tonic has ceased to be a mandatory component of care. It can be used as an additional product to moisturize and nourish the skin due to the content of moisturizing and antioxidant components.

Myth No. 4: Preservatives and parabens are enemies of the skin

In the modern world, there is a widespread belief about the dangers of preservatives and parabens in cosmetics. However, preservatives are necessary to prevent the growth of bacteria and fungi in cosmetic products. Parabens, a type of preservative, are of concern to some people due to their suspected link to cancer. However, the concentration of parabens in cosmetics is strictly regulated by law, and there is no scientific evidence that they are harmful when used in normal quantities.

Myth No. 5: The safest cosmetics are for children and labeled “hypoallergenic”

Many people believe that cosmetics intended for children or labeled “hypoallergenic” are the safest. However, in reality, the name “hypoallergenic” does not always mean the absence of allergic reactions. Manufacturers may use this labeling even if the product contains allergens and irritants. Therefore, products without fragrances or herbal ingredients are most suitable for people with sensitive skin.

Myth #6: Sunscreen causes skin cancer

There is a belief that sunscreens can be harmful to the skin and even cause cancer. However, scientific research shows that using sunscreen reduces the risk of skin cancer by protecting against ultraviolet rays. However, you should remember about the correct choice of product and its regular use in accordance with the recommendations of doctors and cosmetologists.

In conclusion, I would like to note that when choosing cosmetics and skin care, it is important to be guided not only by popular opinions and myths, but also by scientific facts and expert recommendations. The uniqueness of each person requires an individual approach to skin care, and only the right products can ensure beauty, health and self-confidence.

Myth: You need to replace your underwear every year

There is a common misconception that underwear should be replaced every 6-12 months. This opinion is based on the assumption that harmful microorganisms accumulate in laundry, which can lead to infections. However, there is no scientific evidence to support the need to change underwear frequently.

Proper and regular disinfection avoids the accumulation of germs. If underwear has retained its structure and quality after a year of use, there is no need to change it. It is important to note that regular washing and good hygiene play a more significant role in preventing infections than simply changing your underwear.

However, scientific research does not confirm the need for such frequent changes of linen. By properly washing panties, you can avoid the accumulation of germs, and if the underwear has not lost its performance characteristics over the year, it can continue to be used without fear. Despite the risk of bacterial growth in laundry due to the warm and moist environment clothes create on the skin, regular hand washing has a greater impact on preventing infections than frequent washing of clothes.

Myth: To kill germs you need to wash at a temperature of at least 60 degrees

Many people believe that in order to effectively get rid of germs in laundry, it is necessary to wash it at a temperature of at least 60 degrees.
This statement is based on the assumption that only at elevated temperatures can complete disinfection and disinfection of tissues be achieved. However, modern scientific research shows that the situation is not so simple.

For example, although white cotton and linen underwear are often recommended to be washed at temperatures of 60 degrees or higher, for some types of fabrics and types of soil this may be unnecessary or even harmful, since high temperatures can damage the fabrics and cause them to become deformed.

Instead, a more effective method is to use detergents with bleach activators and active oxygen agents, which successfully fight germs even at low temperatures.

For silk linen, it is recommended to use cold water to avoid damaging the delicate silk fibers. Thus, the optimal choice of washing temperature depends on the type of fabric and the effectiveness of detergents in fighting germs at different temperatures.

Myth: Pediculosis is a consequence of poor hygiene

There is a common misconception that lice are caused by poor hygiene. However, in practice, lice can appear even in those who wash their hair regularly and practice good hygiene. These insects have amazing survivability and can survive even in water at low temperatures, which means clean hair and skin are not a reliable defense against them. Removing lice and their eggs, or nits, from your scalp can be a challenging task that requires care and time.

Lice are not able to move long distances: they do not fly, do not jump, and move only short distances, crawling only a few centimeters. They are transmitted from person to person, usually during close contact of heads or through shared personal hygiene items. Therefore, it is important to maintain personal hygiene and avoid close contact with infected individuals to prevent the spread of head lice. Sharing personal care items should also be avoided to minimize the risk of lice transmission.

Transfer of lice from pets to humans is impossible. Among the many species of lice that exist on the planet, only three can parasitize humans, and they are not related to lice that live on animals. Thus, transmission of head lice occurs exclusively from person to person.

Pediculosis can occur even without itching, especially if the number of lice is small or the person does not have an allergic reaction to their saliva.
Lice can only carry typhus pathogens, but in modern conditions this disease is extremely rare in Russia.

Myth: Kerosene and vinegar can help fight head lice

There is a myth that kerosene and vinegar can help fight head lice. However, the effectiveness of such drugs has not been scientifically proven, since clinical studies have not been conducted. Even though these products can actually help get rid of lice, they may come with side effects and risks.
Vinegar is often used as a home remedy for head lice. However, a study conducted in 2004 showed that its effectiveness was low.

Vinegar was less effective than vaseline, which killed 6% of lice eggs. Other home remedies, such as mayonnaise and vegetable oil, also have very little healing effect.

Although lice most often occurs in schoolchildren, about 60% of children suffering from this disease contract it at home from relatives. Despite this, schools are not always the main source of lice infestations because there is not always the opportunity for close contact between students.

Lice cannot survive without food for more than two days. If the lice falls on the floor, the likelihood of re-infestation of the hair is already low. It is recommended to simply wash the floor and wash bedding and underwear at temperatures above 60 degrees Celsius.

Myth: Laser hair removal does not remove blonde hair

This is one of the most common misconceptions when it comes to laser hair removal. This is often due to a lack of understanding of the differences between laser and photo hair removal. It is important to understand that modern laser technologies allow you to remove hair of any color, even light hair.

Although results may vary slightly depending on skin and hair color, laser hair removal is suitable for most hair and skin types. This action is especially effective on light skin with dark hair, since the laser beam is better absorbed by the hair pigment.

Myth: Laser hair removal cannot be done on tanned skin

Another common misconception is that laser hair removal cannot be performed on tanned skin. However, it is not. Laser hair removal is effective on both light and dark skin, including tanned skin. After the procedure, some redness of the skin may be observed, so it is recommended to avoid sunbathing and visiting a solarium until the skin is completely restored. It is also worth remembering to use sunscreen to protect your skin from ultraviolet rays.

Myth: Laser hair removal is a painful procedure and leaves burns after it

Modern laser hair removal technologies have made this procedure virtually painless and safe. Many people still consider it painful and dangerous due to fear of possible burns, but this is a misconception. Modern laser systems ensure the safety and effectiveness of the procedure without causing burns or other damage to the skin

Myth: Laser hair removal removes hair once and for all

Laser hair removal is aimed at destroying hair follicles, which significantly reduces hair growth. However, this does not guarantee complete hair removal forever.

After the procedure, hair growth may resume due to hormonal changes or activation of dormant follicles. Typically, clinics provide a guarantee against hair growth for up to 10 years after completing a course of laser hair removal.

Myth: Laser hair removal can cause cancer

This myth is based on insufficient understanding of the principles of laser hair removal and safety. The laser light used for hair removal does not contain ultraviolet rays, which are known to contribute to the development of skin cancer.

Laser systems are designed with maximum safety in mind and have passed all necessary clinical tests. However, it is important to contact an experienced specialist to carry out the procedure and receive all the necessary recommendations for its safety.
