In the XIV century, at the court of Queen Isabella of France, the wife of King Edward II of England, there was a cruel punishment for the maids of honor, who somehow angered the Queen: they were forced to sunbathe. After the "execution of the sentence" the ladies did not dare to appear at the court because of their appearance inappropriate for an aristocratic person. By the XXI century, everything has changed dramatically, and today there are few women, no matter in what country they live, to get a tan - from light golden to bronze-chocolate. Experienced by the experience of rest at the sea will tell you where and what shade of tan you can get. The closer to the equator, the darker the skin color will be; for a coffee shade you need to go to the Maldives; for bronze - in Sochi, Crimea, Turkey; yellowish-golden will be given by Bulgaria; and the most stable is the dacha and rivers of central Russia. Many are perplexed why this is so: you come from the sea - and in a maximum of three weeks there is no trace of the sunburn, and home sunburn lasts almost until the New Year holidays. In fact, according to the observations of scientists, a sea tan on pale skin lasts no more than twenty days, a light one delays it by forty-five, and a dark one keeps traces of being at sea for up to two months. Consequently, until the New Year holidays, a summer cottage tan can only last for people with a dark skin color. Evgenia Nebova, a medical journalist, gives a completely scientific explanation of this phenomenon. Marine sun rays have a more intense effect (since these are southern latitudes), which means they more aggressively penetrate the surface layer of the skin, at the same time the lower layers are protected by a light-absorbing pigment. As for the country or river sunburn obtained during the entire summer period, here, firstly, the UF radiation is not so aggressive, the tan lays down softer and, therefore, the light-protective pigment simply does not have time to form, and the tan penetrates into deeper layers skin. And secondly, this tan accumulates over a long time, unlike the sea tan, which we want to get here and now in the maximum amount. But dermatocosmetologist, physiotherapist, candidate of medical sciences Laura Bolatova is generally against direct sunburn. She recommends doing this only in the shade. Those who doubt that in the shade there will be problems with obtaining a chocolate skin color are wrong. From the school physics course, it is known about the coherence of the sun's rays, which means that they bypass all obstacles. This means that in the shade you will be able to sunbathe, but there will be no burns from direct exposure to rays. There are also reasons why sea tan "sticks" faster. Water and sea salt enhance the effect of ultraviolet radiation. After getting out of the water, staying in direct sunlight, you risk getting blisters on the skin in places where drops of sea water have remained. Natalia Putilova, Ph.D., dermatologist, recommends preparing your skin for a trip to the sea in advance. It is necessary to remove the keratinized layer of the skin and try to get at least a little river or country tan. Then the sea will not be so aggressive, it will lie on the body softer and last longer. The question is often asked, which tan is healthier? Doctors have a double opinion on this. On the one hand, sunburn is photoaging, it is photodermatitis, it is allergic to sunlight, in some cases it is cancer of the skin. So, Doctor of Chemistry, Professor Eduard Rozantsev claims that a regular summer sunburn can also get a skin burn that can cause photodermatitis or cancer.If you expose your body to UF radiation from 11 to 13 o'clock, when the sun is at its zenith and its waves are especially short, then you are guaranteed a harmful tan. At this time, ultraviolet light becomes especially hard, forming free radicals. Chemists are sometimes referred to as their active form of matter. Such activity is fatal to humans. When, at the end of the summer season, you go to a dermatologist for nodules, blisters, papules or sudden urticaria protruding on the skin, this is nothing more than photodermatitis, in other words, various forms of allergy to the sun. Dermatologist Oleg Buchinsky explains that most often photodermatitis, which turns into a cancerous stage, is provoked by moles on the body and spots that appear during tanning, called nevi. If you notice such a spot in yourself, you need to do everything so that the sun's rays do not fall on it at all. Another unfortunate consequence of sunburn is photoaging. When the tan wears off, we notice deeper wrinkles and noticeably sagging skin in its place. And this is inevitable. On the other hand, giving up tanning at all is not an option. This will further harm the body. Ultraviolet light is the only source of vitamin D for our body. Only under the influence of this vitamin, the body is able to assimilate calcium, which gives strength and beauty to bones, nails, hair. The "hormone of joy" serotonin is also produced only under the influence of the sun - it is no coincidence that there is such a thing as an autumn or winter depression - a period when the sun is at its minimum. So you need to sunbathe. It doesn't matter where - by the sea, a river or a summer residence. The main thing is to do it wisely.
