There is an opinion that being on the sun has a beneficial effect on human health, and in winter the lack of sunlight should be replenished, visiting the solarium. We decided to check if this is so.
They write about the benefits of being in the sun for the human body Portalsdedicated to a healthy lifestyle. Manufacturers sunscreen, news resources and Internet users in their Blogs It is recommended to take sun baths to strengthen health, that is, to be in the sun intentionally and for a long time - for example, on the beach. On sites spa centers and specialized online stores even Approvedthat in winter, when the sun is less active, you need to go to the solarium.
The benefits of sunlight are usually associated with obtaining vitamin D. It is really necessary for the body for normal life, and in many people (some researchers call the figure in billion Man around the world) He is in short supply. Our body can independently produce one of the varieties of this vitamin - D3 - from cholesterol under the influence of ultraviolet radiation. Nevertheless, it can get And from food - for example, adding oily fish or egg yolks to the diet. Another, identical in effect, a variety of this substance - D2 - can be obtained from food additives. In general, how Mark Specialists of the Harvard Medical School, it makes no sense to expose themselves to ultraviolet radiation when you can get a sufficient amount of vitamin D with food.
"Checked" already Disassembled Popular statements about the benefits of vitamin D to strengthen bone health, prevent cancer, treatment of depression and coronavirus prevention. Studies have shown that the positive effect of vitamin to achieve these goals causes disputes in scientific circles, in the worst - it is completely refuted by the results of research. Therefore, the benefits of this substance - and, therefore, solar baths in order to obtain it - is somewhat exaggerated.
But about the harm of the tanning, scientists have no disagreement. In itself a change in skin color under the influence of the sun is a protective reaction organism that is trying to develop more Melanin, substances responsible for pigmentation and capable of absorbing dangerous UV rays, protecting the skin from damage. If melanin does not cope with the intensity of the effects of ultraviolet radiation, a person can get a sunburn.
WHO specialists Markthat the effects of ultraviolet radiation can cause not only sunburn, but also premature aging, skin cancer, eye diseases, including leading to loss of vision, etc. It can also suppress immunity, which, in turn, leads to various diseases. With this opinion agree and specialists of the US Environmental Protection Agency.
In 2008, specialists of the Brookhevenskaya National Laboratory of the US Department of Energy, as well as their colleagues from the University of Oslo and the Norwegian Institute for Research of Cancer built The digital model of ultraviolet radiation on a person, and also studied the statistics of incidence and survival with various types of cancer of internal organs, depending on the place of residence of people. It turned out that in the northern hemisphere, residents of more southern latitudes, more often in the sun and, accordingly, receiving more vitamin D, less often die from cancer of internal organs than those who live north. It is noted that skin cancer and other oncological diseases in the regions are closer to the equator more often.
US Disease Control Center (CDC), referring to WHO data, Notesthat in order to obtain the required amount of vitamin D in the sun, you need to be only two to three times a week for 5-15 minutes. American Academy of Dermatology does not recommend Use sunbathing or solarium as a source of this substance, giving preference to food additives and food rich in vitamin D. Experts note that there is no safe dose of ultraviolet radiation - in the sun or in the solarium - which would provide a sufficient amount of vitamin D without increasing the risk of skin cancer. Experts of the skin cancer Foundation They sayWhat is better to avoid tanning at all, and both natural - under the sun, and acquired in a solarium.
As for solariums, the International Cancer Research Agency for WHO recognizes Devices for artificial tanning by carcinogenic. By data The US Ministry of Health and Social Services, people, at least once tanned in the solarium, have a 22% higher risk of developing melanoma - one of the most dangerous types of cancer. American scientists in 2012 came to conclusionthat the risk of getting skin cancer due to a solarium is higher than lung cancer-due to smoking. In many countries of Europe (for example, in France, Spain and Germany), the use of solers by minors forbidden Due to health risks. And in Brazil and Australia, such a ban He was introduced For the entire population.
Thus, most experts agree that long -term (more than 15 minutes) and frequent stay in the sun carries more harm than benefits. The disadvantage of vitamin D, which is really produced in our body thanks to ultraviolet, can be replenished in safer ways. The tan, although it will contribute to the achievement of this goal, carries the risks of skin cancer, reduce immunity, develop eye diseases, etc. If we talk about solariums as a method of obtaining vitamin D, they are so unsafe that in some countries their use is even prohibited or seriously limited.
