Sunburn in the mountains in winter. Is it possible to tan in cloudy cloudy weather? How likely is it to get a tan if the sun is covered by clouds

It is under the influence of ultraviolet radiation that a tan appears on our skin. But it can be not only useful, but also dangerous. And doctors tirelessly remind us of its harmful effect before the start of the next holiday season.

There are several common myths that have been misleading more than one generation of holidaymakers and bronze tan lovers. One of them, through the glass you can not sunbathe. This is not true. Ultraviolet rays calmly pass through ordinary window glass, and through polyethylene, and even through thin transparent fabrics with a rare weave, such as nylon. Sunburn does not appear because the intensity of such exposure is insufficient. Transparent and translucent surfaces absorb some of the rays, thereby reducing their impact. And either does not occur at all the desired chemical reaction in our body, or the process of the appearance of pigment melanin is so slow that it is better to do something more useful.

It is also believed that in windy weather it lights up faster. On the one hand, this is true. Since sweat contains uracanic acid, which protects our skin from excessive ultraviolet radiation. It is more difficult to sweat in windy weather. Therefore, the body is deprived of some part of the protection. It turns out that those people who sweat less, being under the sun, sunbathe faster. But they are also more likely to get a sunburn.

Even the intensity and speed of tanning depends on the wavelength, which is different for ultraviolet radiation. The kind of waves that trigger the process of releasing pigment melanin in our body does not reach the surface of the earth everywhere. But the higher you climb the mountains, the more powerful radiation you will receive. Moreover, its negative impact will increase much faster than the ability to tan beautifully. Therefore, in the mountains it is better to protect your body as much as possible from excess ultraviolet radiation.

Remarkably, vitamin D synthesis begins at a lower intensity ultraviolet rays than is required for the appearance of a tan. If your goal is vitamin D, then cloudy weather is quite suitable for taking sunbathing.

Everyone's sensitivity to ultraviolet radiation is different. Moreover, it can change in the same person. It all depends on the state of health and fitness. The sensitivity threshold also varies from season to season. The most susceptible organism is in spring - April-May.

We sunbathe not only from exposure to direct sunlight. Scattered ultraviolet light penetrates unhindered even through dense clouds. Clouds block only direct radiation. And getting sunburned in bad weather is quite real. It's just that you have to spend almost a whole day on it. fresh air naked.

To this day, the most popular type of beach holiday is when you want to soak up the sun, get away from active everyday life and, of course, shine with a bronze tint after your vacation. beautiful body. But since the vacation, as a rule, is not as long as we would like, and the weather is not subject to our desires and plans, there is always a high risk of not getting the desired tan due to bad weather. As soon as the clouds are gathering overhead, the majority of vacationers (of course, the beautiful part of humanity is in the advantage) falls into a mini-tantrum: I won’t have time to tan by the end of the holiday! Is it really? Or is it still possible to sunbathe in cloudy weather?

We will not torment and “go away from the topic”, but will immediately answer exciting question: it is quite possible to get a tan (and even get burned!) under the clouds. Many people find that cloudy tans go on more evenly and last longer. To understand whether this is a myth or reality, it is worth studying in more detail the mechanism of solar radiation and understanding how a tan appears.

The sun is the main source of ultraviolet radiation, and it is UV rays that, acting on a living organism, contribute to the formation of a tan (and many other important processes). In turn, in the ultraviolet spectrum, 3 classes of rays are distinguished (UV-A, UV-B and UV-C), each of which hits the Earth in different amounts and affects the human body in different ways. The most dangerous for humans are C-rays and B-rays, but nature created the ozone layer precisely in order to prevent them from reaching the Earth and all living things. A-rays have the lowest level of radiation, they freely penetrate the Earth even through clouds, but in a slightly smaller amount, and provide the body with invaluable benefits, and with it a lot of harm. So, premature aging of the skin directly depends on the amount of sunbathing: and the more the skin is exposed to solar "burns", the faster it fades, losing its elasticity and firmness, since A-rays, penetrating into the deep layers of the epidermis, destroy elastin and collagen cells .

Actually, the tan itself is just a protective reaction of the body to the action of UV radiation. If direct A and B rays fall on human skin, then a special pigment, melanin, begins to be actively produced in the cells of the skin, which protects the lower layer of the epidermis from the damaging effects of UV rays (from sunburn and overheating (heat stroke)). In turn, along with the formation of this pigment, other important processes are also triggered - for example, the production of vitamin D.

Few people think about the importance of the processes that occur in the body during sunbathing, but the fact that a person needs these procedures is an indisputable fact. Another thing is "overdose". After all, only what is in moderation is useful. Stories about melanoma (an oncological skin disease) are far from intimidating, but a warning: you should not get involved in sunbathing, but to get not only beautiful from a tan appearance but also health benefits, it is important to observe simple rules:

• It is better to sunbathe in the shade (at least, the head must be protected from direct sunlight).
• Do not sit out "in the sun" (increase the time spent under the sun's rays gradually).
• Apply sunscreen to the skin.
• Use special cosmetics after sunburn.
• Take into account the “activity” of the sun (“dangerous” height above the horizon, the sun takes from 11 am to 4 pm).

Is it possible to consider cloudy weather as a kind of shadow? On the one hand, yes, because clouds block a quarter of the direct sunlight. At the same time, scattered radiation passes through them unhindered, and a person receives a prophylactic dose of ultraviolet radiation simply by being outdoors, even on a cloudy day. As for cloudy beach weather, of course, the production of melanin will slow down a little, but this is only good - such a tan will lie more evenly and last much longer.

The main mistake of "sunbathers" in cloudy weather is the refusal to apply sunscreen to the body. As a result, having been under the clouds all day, vacationers face burns in the evening. This is due to the fact that the ultraviolet did its job, and the body was unable to defend itself without additional support.

It is worth noting that applying special creams with SPF protection to the skin of the face is main part prevention of premature aging of the skin. Unfortunately, many ladies ignore this advice cosmetologists and in pursuit of a bronze tint of the body receive unpleasant surprises: flabbiness, dryness, sagging skin, wrinkles and other troubles, up to cancer.

Based on the foregoing, we conclude: everything is good in moderation, and cloudy weather is not a reason to be upset if it accompanies a long-awaited vacation. A tan will definitely appear, while the risk of getting an unwanted burn will be much reduced.

Everyone who decides to spend their holidays on the coast of the sea or the ocean, and just in the country, is interested in whether it is possible to get a tan in cloudy weather, and will there be a result from this? Will you get a quality tan under the clouds? And such a question is correct, because it is not known what surprises the weather is preparing, and getting a uniform tan after rest is a natural desire of every vacationer.

Does the skin tan if it's cloudy?

So, first you need to find out what is a tan? Sunburn is a reaction of the human body to ultraviolet rays. It manifests itself due to the production of a certain substance by the skin - melanin, which, in fact, takes over solar radiation. And it doesn’t matter if you tan in cloudy weather or under bright rays.

Radiation can be divided into three parts:

• UVA - long wavelength rays. Virtually no Negative influence per person;
• UVB - medium wave rays. Are dangerous in large doses;
• UVC - short wavelength rays. The most dangerous and poisonous. They do not pass through the atmosphere, so they do not get on the skin.

It can be concluded that a person comes into contact primarily with UVA and UVB rays. They have the ability to penetrate transparent objects, water, fog.

Can you get a tan if the sun is behind the clouds? When a person tans in the open sun, melanin is released quite quickly, especially if the body is not yet accustomed to constant exposure to direct ultraviolet rays. This explains the fact that most people immediately "burn out" on the first day of their stay on the beach.

Important! The tan that the skin gets in a few hours disappears after about 2-3 days if you stop sun exposure.

Sunbathing on cloudy days , melanin will be produced slowly and more evenly. So the tan through the clouds lays down slowly, but smoothly and evenly. The skin takes on a ruddy color, however, this process takes much longer, but the result is better!

This has its advantages - the tan is even, without sharp transitions, and the skin does not lose moisture and its water balance is not disturbed.

Can you get a tan on a cloudy day?

Sunbathing in cloudy weather is possible even for people with the most fair skin. To get a beautiful, chocolate color, you must follow the recommendations of cosmetologists-dermatologists and adhere to the following simple rules for tanning in cloudy weather:

• Everything has its time. What hours can you get a tan if it's cloudy? You should sunbathe only before 10:00 and after 16:00. It is at this time that the rays of the sun penetrating through the clouds are not too radioactive and do not harm human health;
• Water to help. Sunburn in cloudy weather fits perfectly in the water. According to experts, through the water the sun's rays act more actively, and better "stick" to the skin. Therefore, it is worth swimming more often, and when leaving the water, you do not need to immediately run to wipe yourself with a towel - it is better to let the skin dry on its own;
• The right remedy. It is recommended to use sun protection creams with a low SPF factor. After all, the rate of melanin production slows down in the shade. Protective equipment with high protection can be used with individual intolerance to ultraviolet radiation.

When tanning, you must always remember that each organism is individual, therefore it is necessary to monitor the condition of the skin and prevent it, because if the skin is too susceptible to solar radiation, even when tanning through the clouds, it can be injured.

Is a tan good for you?

Scientists have long found out that tanning has both beneficial and negative properties (this also applies to tanning in cloudy weather). Useful ones include:

• Getting the body of vitamin D, which he needs especially in the winter and autumn periods.
• Endorphin production. In common parlance, it is called the hormone of happiness. Its presence is considered mandatory for normal life.
• The sun's rays help the body Better absorption of certain fats, proteins and micronutrients.
• Regular sunbathing helps reduce the risk of diabetes and diseases associated with the cardiovascular system.

It may also be noted negative sides tan:

• Photoaging. Occurs due to solar exposure. Manifested by skin aging, loss of elasticity.
• Burn formation. It can manifest itself in the form of severe reddening of the skin, burning, in the form of blisters.
• Promotes the formation of herpes, (metabolic disorders), exacerbation of chronic diseases.
• Promotes the formation of cancer cells.
• Possibility of heat stroke. Manifested by dizziness, vomiting, loss of strength, drowsiness.

But note that all the negative consequences are possible only with the abuse of sunbathing.

Important! No need to abuse the tan, because the excessive production of melanin contributes to the rapid aging of the skin and the whole body. That is why it is recommended to use scrubs and balms after the beach, which moisturize and nourish the skin and hair.

How to make a tan safe?

Is it safe for health to sunbathe in cloudy weather? You can, but you need to do the following:

1. Always use sunscreen, even when you go swimming and know that you will stay in the water for a long time! You need to apply the product every two hours.
2. Follow the regime Sunbathing is allowed only at certain hours. This was written above - before ten in the morning and after four in the evening.
3. Moisturize and nourish the skin before and after the session.

By following these simple rules, you you can get a beautiful and safe tan in cloudy weather.

How to maintain a bronze skin tone?

It depends only on you whether the tan will last in cloudy weather or whether it will immediately disappear. There are several tricks to get it. And I'll tell you what:

• Cleanse your skin. Scrub it the day before going to the beach.
• Get Healthy Vitamins Inside and Out. Good friend in this case, it is beta-carotene, before and after the procedure, you can eat foods containing it (for example, carrots, sea buckthorn, apricots). And outside, apply oil or body cream with vitamin A and E.
• Hydrate your skin thoroughly. This can be done with a moisturizer, lotion, body milk. Apply cosmetic regularly, and every time after sunbathing. If you neglect such care, then the upper skin flakes will die off more intensively and, therefore, along with a chocolate tint.
• Give food by using quality nourishing cosmetics. The product should contain vitamins, natural oils and have good composition. Also, lovers home care can pamper themselves with natural homemade masks.

Now you know whether it is possible to tan through the clouds at the sea, in the country, in nature, and, in general, everywhere.

It should be summed up to get a uniform, beautiful tan it is possible not only in the open sun, but also in cloudy weather, except that it will take much more time to do this. After all, after all, but from vacation I want to bring not only pleasant memories, but a bronze tan. Have a good rest, pleasant sunbathing and good mood!

HELLO SUN!

Holy eye of the day, a yearning giant!
I myself carried your captive flame in my chest,
Pierced by sight like a white diamond
In the crimson darkness of the emerging universe...

M. Voloshin

The Sun is the closest star to the Earth, on which nuclear reactions with the release of a huge, according to earthly concepts, amount of energy. The temperature on the surface of the Sun is +6000°С, and in the depth of the ball it reaches +40000000°С. Spots periodically appear on the surface of the Sun, which appear almost black through a light filter against this more than light background. The spots correspond to the locations of strong magnetic fields. Their temperature is +4500°С. In the upper layer of the solar atmosphere (the chromosphere) there are flashes of nuclear matter - prominences.

from the sun to earth's atmosphere electrically charged particles are transmitted, they cause a change magnetic field Earth (magnetic storms). The cycle of solar activity and therefore the alternation magnetic storms on earth - 27 days. In addition, every 11 years (sometimes with disruption of the rhythm), solar activity especially increases, and astronomers declare a "year of the restless Sun." Most of the earthly tragedies and catastrophes, especially those related to health, happen in such years.

The distance to the Earth (150 million km) sunlight passes in 8 minutes. Beyond the visible spectrum are infrared (thermal) and ultraviolet rays. Attempts to create an "artificial sun" at least in the laboratory have so far been successful only in the works of science fiction. A quartz lamp, under which you can also sunbathe, is a miserable and unsafe surrogate for the world's luminary. Without the Sun, life on Earth could not have arisen, but the Earth's atmosphere reflects, traps, and scatters most of the sun's rays. When there are too many, life is also impossible.

What is sunburn?

Sunburn is the skin's reaction to exposure to ultraviolet rays. Destructive to all living things, invisible to man ultraviolet rays are trapped by the earth's atmosphere, especially its ozone layer(which in recent times, to our general dismay, he lost a lot of weight).

Only a small part of the rays reaches the earth's surface. But even from this small part, the human body defends itself by accumulating a pigment - melanin - in the skin cells. We have not understood anything yet, we have not felt anything, and in the outer layer of the skin the struggle for our life has already begun. The more pigment, the more difficult it is for the rays to penetrate the subcutaneous layers in order to produce their destructive effect - to cause the breakdown of protein molecules and, consequently, the death of the tissues themselves. After 6-10 hours, redness appears on the skin - erythema. After 3-5 days, erythema turns into pigmentation due to the accumulation of melanin in the skin. Moderate tanning increases the protective properties of the skin.

Why do some people tan faster than others?

The ability to synthesize melanin in greater or lesser quantities is an individual property of the body, it is set from birth and is inherited. Therefore, brunettes sunbathe better than blondes, and residents of tropical countries may not sunbathe at all.

Who are albinos?

These are living organisms, by nature completely devoid of pigment. Albino people have pink skin and completely white hair. Even their eyes have a pinkish tint, because the blood capillaries in them shine through the colorless iris. Albinos are not able to sunbathe and suffer terribly from sunburn in summer. Born in the tropics, they are doomed to die from the sun unless they move to a country with temperate climate. Fortunately, complete albinos are more common among animals (eg, rats, mice, rabbits).

What determines the intensity of sunburn?

The most important thing for tanning is the height of the sun above the horizon (hence, the latitude of the area, time of year and day). Sunburn is the stronger, the more transparent the atmosphere and the more sunlight is reflected from the surface of the earth. Climbers in the mountains, especially in the snow zone, wear gloves and dark glasses, put 5-6 layers of gauze on their faces and smear their faces with oil every day. sunscreen. But despite all these measures, in alpine camps they always determine by their tan who has descended from the summit, and who is still preparing for the ascent.

A day spent in the mountains (even in the Crimean ones, where the atmospheric layer is a kilometer thinner than above sea level) makes it possible to tan better than several days of monotonous and sometimes painful lying on the beach.

The protective function of the skin decreases with long-term use of certain drugs (sulfamides, quinine, arsenic, iron preparations, etc.). Sensitivity to ultraviolet rays always increases in spring.

Experts strongly recommend that you start taking "sunbathing" only after talking with your doctor. Very well. But we would add that in our stressful time, a person should especially listen to the voice of nature and constantly study himself, become a doctor for himself. The Spanish philosopher B. Gracian (1601-1658) said: "It is foolish to appeal to Hippocrates for health after forty."

Why is the Crimean sun dangerous?

Even the slave traders of past centuries punished slaves transported across the ocean by throwing them bound on the deck under the sun.

Aborigines of sunny countries still recognize visitors by their ineradicable habit of sunbathing.

The summer beaches of the southern coast of Crimea are seen from the plane as yellow - from the myriad of human bodies under the sun. Yes, most vacationers understand summer holidays in the Crimea as a happy opportunity to spend a vacation (or the entire period of a sanatorium trip) on the beach - to lie under the sun, playing cards, leafing through a magazine, sipping beer. When they return, they must brag to their colleagues, “report” to their relatives. How? Of course, tan!

It is unlikely that in our time anyone does not know that excessive exposure to the open sun is harmful and dangerous. The smallest of troubles is simply getting burned and then being forced to hide in the shade for several days. The biggest one is to get a malignant neoplasm, the possibility of which is especially high for people with age spots on the skin (moles) and generally higher for blondes, especially for those who have already burned to blisters.

In between these extremes lies a long, unhappy list of ailments that can be caused by an indefatigable thirst for a tan. This is an increase in blood pressure, increased heart rate, arrhythmia, headache and weakness, which does not go away even after resting in the shade. Exacerbation of chronic diseases can occur, especially diseases nervous system, destruction of red blood cells and hemoglobin. Finally, as it has recently been established, an excess of ultraviolet rays causes a weakening of the immune system, which manifests itself gradually - diseases that he had never heard of before suddenly begin to stick to a tanner. The medical staff of sanatoriums often have to observe vacationers who hope to “fry” bronchitis and tonsillitis earned in rainy cities under the Crimean sun, and instead of recovery they switch to bed rest.

Being under the sun without a hat is harmful for everyone, and for the elderly and for those who are prone to hypertension, it is extremely dangerous. Overheating of the head can lead to sunstroke and even stroke. Luckily, the Turkish industry has provided us with enough individual sun umbrellas, so now the beaches should look colorful from the plane.

How long do doctors recommend staying in the sun?

Total solar exposure, according to the recommendations of the World Health Organization, should not exceed 60 MEA (“minimum erythema doses”) per year. In practice, the duration of exposure to the direct rays of the Sun is at the beginning 5-10 minutes. and gradually brought to 40-50 minutes. in a day. During the vacation period, one cannot cross the line between the health that the Sun gives, and the diseases with which it punishes those who spend too much time under its direct rays.

What is the benefit of sunburn?

Once one of the authors of this book taught biology at a school in Yalta. I remember that in the fifth grade there was a new student from some northern city. The boy was shorter than the others, bow-legged, with a thick belly and a large head. Newcomers, and even visitors, were not very favored in Yalta, but this was treated with respect. “I had an English disease,” he said on the day they met. And say "rickets" - so, I suppose, and teased!

Why English? Probably because of her constant, classic English fogs.

Everyone needs the sun! Vitamin D is synthesized from cholesterol in the human and animal body under the sun. When there is not enough sun, children are prescribed fish oil to artificially saturate them with this vitamin, which regulates, first of all, phosphorus-calcium metabolism in the bones. Alas, fish oil does not always help, and softened bones bend under the weight of the body.

About how the sun is needed, they knew in Ancient Egypt. According to Herodotus, the Egyptians arranged special terraces for sun exposure, like modern solariums. Later, a proverb was born: "Where there is rarely sun, there is often a doctor."

With solar “starvation”, resistance to diseases, physical endurance and mental performance decrease, the course of chronic diseases is aggravated, the strength of tooth enamel decreases, regeneration worsens (recovery after fractures) bone tissue. In children, in addition, growth and development slow down.

Residents of industrial cities with a polluted atmosphere, through which it is difficult for the rays of the sun to break through, are prone to these troubles, especially in the northern regions, and even more so at the end of winter. There, for partial replenishment of solar deficiency, doctors recommend taking irradiation with quartz lamps.

How does the sun affect the human body?

Heliotherapy - sun treatment. It is a powerful preventive and healing tool. Under the sun's rays, overall performance increases, resistance to colds, infections, and adverse external factors.

The infrared rays of the sun are predominantly thermal action, penetrating the body to a depth of 4 cm.

Visible rays are perceived by the retina, increasing vitality. The general color scheme of the Crimean summer contrasts the gray "landscape" of industrial cities with all the colors of the rainbow:

The RED ball of the rising Sun in the early fresh morning brings a burst of optimism and hope, gradually coloring the coast. ORANGE-YELLOW tones of warmth and joy. Varied GREEN shades of subtropical vegetation create a feeling of comfort. The boundless BLUE sea and the clear BLUE sky soothe the soul. PURPLE evening tones with golden lights and the famous moon path that connects the shore with the endless expanses of space, appeal to harmony with the Universe.

Ultraviolet (UV) rays penetrate to a depth of only 1 mm, but cause a variety of reactions in the tissues of the body. Blood viscosity decreases, cholesterol levels decrease, which is important for the prevention and treatment of atherosclerosis. Immunity increases, tissue respiration increases, metabolic processes improve. UV rays have a detrimental effect on viruses and bacteria, promote the synthesis of protein, vitamin D, enzymes, hormones.

Can you sunbathe through window glass?

You can sunbathe, you can not sunbathe. Mineral glass does not transmit ultraviolet rays. If the house is warm, then even in winter you can try to sunbathe through the open window. There are eccentrics who specifically replace window glass with plexiglass (organic glass). It's always summer for them!

Is it possible to sunbathe in clothes?

Matter of light colors (natural silk, crepe de chine, cotton voile) transmits 30-60% of ultraviolet rays. Less than 10% of the rays pass through linen, staple, satin, dark-dyed cotton fabrics, and from 30 to 77% through synthetic clothes. In general, in the summer they sunbathe through clothes. Therefore, if before lunch you had an excursion along the sunny route, then after lunch on the beach it’s better not to go out from under your “fungus”!

Is it possible to sunbathe in the shade?

The sun's rays are scattered in the atmosphere and reflected from white cumulus clouds (up to 50%), from the sand and pebble beach (28-33%), from lawn grass (26%), from the sea surface. Therefore, the tan "sticks" to those who are in the shade, but outdoors and not far from a place lit by the sun. This is how it is recommended to sunbathe in the first 2-3 days of your stay on the Black Sea coast.

Does a tan stick on cloudy days?

Ultraviolet rays penetrate clouds, so bright sun is not necessary for tanning. Of course, such a tan requires a longer vacation.

At what age can you take "sunbathing"?

The skin of children is much more sensitive to the sun than the skin of adults. In addition, children love to splash in the water and then have to warm up under the sun for a long time. Therefore, from 11 am to 4 pm it is better not to bring them to the beach at all. But since this rule is usually not respected and loving adults, for their own convenience, adjust the children's regimen to their own, you must at least strictly monitor the baby - wipe it after bathing and strictly hide it under an awning. Just remember that small children can get burned even under an awning, and children under one year old should not be taken out into the open sun at all. sunburn received by a child (we note, through the fault of the parents) can unpredictably affect his health even in adulthood.

What time of day is the best time to get a tan?

The best tan is in the morning, until 10-11 o'clock, when there is still little water vapor in the air, and there is no real heat. Then, until 16-17 hours, you should hide in the shade.

It is best to come to the beach early in the morning. This kind, harmless sun, cool and transparent sea, deserted beach, seagulls on the pier and on the rocks, the whole awakening world creates your mood, drives away winter fatigue and unnecessary thoughts. True, to get up early, you need to go to bed early, but it’s a pity in the evenings! So take a nap after dinner.

Susceptibility to UV rays is increased in fair-skinned women during the period of "critical days", with thyroid diseases, iodine, calcium, and vitamin deficiencies.

Remember! Uncontrolled exposure to the sun leads to the formation of wrinkles, premature aging of the skin.

Who shouldn't sunbathe?

You can not be in the open sun for people with acute diseases and bleeding, with circulatory failure II and III degree, with angina pectoris, bronchial asthma. In addition, there are people with increased skin sensitivity to sunlight. The sun burns them so much that it causes skin diseases in a short time. You can not sunbathe people with malignant and even benign neoplasms.

SUMMING UP

Sunbathing under a clear sky is taken in the morning until 11 o'clock and in the afternoon - from 16 o'clock. The rest of the time it is recommended to be in the shade of a lattice awning or umbrella.

On the beach, you should wear a light-colored hat, and protect your eyes with dark glasses. Sunbathing is taken lying down, the head should be in the shade.

Don't sleep on the beach! It is necessary to change the position of the body - evenly distribute the tan.

Do not sunbathe on an empty stomach or immediately after a heavy meal.

You need to take care of your health! If you experience a burning sensation of the skin, a headache, stop sunbathing.

How to treat sunburn?

If you still “burned out” (pronounced redness and soreness appeared), you should stop sunbathing for 2-3 days, and wipe your skin with alcohol, cologne.

What is sunstroke?

There is a sudden weakness, a feeling of weakness, headache, nausea. It is necessary to transfer the victim to the shade, free from clothing, put cold compresses with ice on the head and heart, or simply pour cold water over.

Is it acceptable to stay on the beach for people prone to sun allergies?

With increased sensitivity to the Sun, it is better to be on the beach only in the early morning. The use of special sunscreens is shown. On such creams, lotions, gels, the sun protection factor - SPF is indicated. The higher its value (10, 12, 18, 40), the more effective protection against UV rays. For example, if the cream is labeled SPF10, then under the protection of this cream, you can stay in the open sun 10 times longer than usual. Sunscreens are applied to the skin 15-30 minutes before the start of the sunbath.

Is it possible to tan in winter?

Direct solar radiation by December weakens, compared with July, more than twice. The amount of ultraviolet rays scattered in the air decreases even more sharply, among which safe, longer wavelengths prevail in winter. In January, the radiation is slightly higher than in December (with the same clear sky).

Getting "erythema" in winter is almost impossible. However, it is possible to get a good dense tan, especially in the Crimea, where the winter sun is five times more active than, say, in Moscow. For winter sunbathing, special pavilions are arranged with foam beds or, better, individual cabins covered with plastic wrap.

Beautiful winter tan useful and safe. It can be considered a real success, for which it is worth coming to the resort in the off-season!

From the book by V.V. Ezhov, D.N. Tarasenko "Secrets of Crimean health", "Business-Inform", 2002, Simferopol
