Solarium: benefits and harms
The main positive effect of tanning is the fight against winter depression, which is associated with a lack of natural sunlight. According to experts, about 30-40% of the population of Russia is subject to a similar depression.
In natural sunlight, “B” type UV rays predominate, affecting mainly the upper layers of the skin, while tanning lamps emit “A” type rays - long, affecting the deeper layers of the skin. Unlike ordinary sunlight, the radiation from solarium lamps dehydrates and dries the skin more, and also leads to the formation of free radicals that accelerate the aging process and can even cause various neoplasms.
There is mercury in the quartz lamp bulb, which, under the influence of an electric discharge, evaporates inside the bulb, making the special coating glow. The spectrum of this glow contains a range of both visible and UV rays - which is why sunscreens also need to be used in a solarium. How to apply the cream on the face and what protection factor SPF is recommended to use?
What is the difference between a natural tan and a solarium?
Under the influence of ultraviolet (UV) rays, the pigment melanin is produced in the upper surface of the skin (not to be confused with melatonin), giving it a tanned color. The natural source of UV rays is sunlight, and artificial - quartz lamps.
Under the influence of ultraviolet radiation, oxygen consumption is increased by tissues and vitamin D is synthesized, which strengthens bones and muscles. The tanning bed also dries and disinfects the skin, which leads to a reduction in pores and acne.
How to sunbathe in the solarium?
Eyes must be closed during a tanning session, otherwise it is easy to get a retinal burn, which leads to blindness. It is safest to use special glasses, since the eyelids pass a certain percentage of UV rays.
Also, remember that vitamin D is only formed when there is a greasy film on the skin. Thus, it is not recommended to sunbathe after a shower or a pool when this film is not available - you enhance dehydration of the skin, and do not get any benefit from tanning.
Solarium - contraindications and dangers
Tanning and the production of melanin is a protective reaction to radiation, and the body spends certain immunity resources on the manifestation of tanning. If you have a cold or SARS, then a solarium is not the best way to overcome them, and there are other methods for this.
In addition, it is also very important to sunbathe in moderation, to follow the recommendations of the equipment manufacturer, and also to ensure that there are always new lamps in the solarium - with the increase in operating hours, radiation becomes more and more dangerous.
A tanning bed in the northern countries, to which Russia belongs, is a necessary element to combat winter depression. But during tanning sessions, you must strictly observe safety measures: wear glasses and use a moisturizer.
