Summer heat ... Outside the window - about thirty, and hangingin the cloudless sky a bright white disk of the sun more burning heat earth. In weather like this to be in the city - a nightmare, drawn to nature, closer to the water, where you can lie down on the grass or on the sand and take a relaxing sun bath. But, unfortunately, the rays of light is not so harmless, and not only in the southern countries, and even in our mid-latitudes. Therefore, failure to comply with the simplest rules can lead to very serious consequences.
The sun is the source of life on our planet. It was through his radiation in plant cells photosynthesis and accumulates energy that is then transmitted to animals and humans. But grace was shining poses a threat that just need to be considered.
The impact that has solarradiation on human can be classified into several types. The first - the impact of the ultraviolet part of the solar spectrum. It is this part of the spectrum is responsible for giving our skin a beautiful chocolate color so the UV lamps used in solariums for creating artificial tanning. We do not think about the fact that a tan - a protective reaction of the body associated with the development of special pigment - melanin, capable of absorbing ultraviolet radiation and protect the deeper skin from radiation damage. However, this mechanism can not fully protect against the risk. Solar ultraviolet light damages skin cells and small capillaries, resulting, in the case of high intensity, to deep and painful burns.
Но это не самая большая опасность. Разумеется, солнечный ожог — вещь весьма неприятная и болезненная, но редко кто доводит себя до повреждений, угрожающих жизни, хотя, если заснуть на пляже под полуденным солнцем, то можно сразу резервировать койко-место в ожоговом центре. Другая угроза — скрытая.
Ultraviolet radiation causes irreversiblechanges in the structure of cells, as a major factor in the accelerated aging of the skin and the risk of skin cancer, especially the most dangerous of its kind - melanoma.
Modern cosmetology offers a simple andan effective method of protecting against the harmful effects of ultraviolet radiation - is to use special creams. The correct cream provides emission reduction to practically safe level. Cream should not be neglected even in our mid-latitudes because of the decrease in the ozone layer, the intensity reaching the earth's surface ultraviolet every year becomes more and more. And in the case of a trip to the southern resort, the use of cream is an absolute necessity.
What do you do if you still gotsunburn? Above all, remember - this is a serious disease state, and in any case can not treat it lightly. Immediately move into the shadows, the continuation of tanning is fraught with very serious damage to the skin. The use overlay wet compress, it is moist, but not wet as first aid. You can also put on a burn site one percent gidrokartizonovuyu ointment and take pain killers, just be careful, all medicines can cause allergic reactions, so the possibility of using this or that funds should always check with your doctor. In the absence of special anti drugs, you can use folk remedies, primarily drawing on the skin of dairy products - yogurt, yogurt or yogurt.
Only one important condition - they should not beno additives, or, especially, chemical dyes. Remember that sunburn - a dangerous condition, and as soon as possible consult a physician.
Другим грозным явлением, прямым следствием воздействия солнечного излучения на организм человека, является солнечный или тепловой удар. Это — болезненное состояние, расстройство работы головного мозга вследствие продолжительного воздействия солнечного света на непокрытую поверхность головы. В легких формах наблюдается общая слабость, головная боль, учащение пульса и дыхание, расширение зрачков. Если не принять срочных мер, симптомы усиливаются, резко повышается температура, появляется неуверенность движений, нарушение координации и шатающаяся «пьяная» походка. В дальнейшем развивается изменение сознания, от легкой степени, до комы, судороги, галлюцинации, температура поднимается до 42 градусов. Развитие этого состояния может привести к смерти. Следует немедленно перенести пострадавшего в тень, освободить от верхней одежды, смочить лицо и грудь холодной водой, по возможности охладить голову, часто обмахивать, обеспечивая доступ свежего воздуха, и главное — срочно вызвать бригаду скорой помощи.
Remember: The sun - an inexhaustible source of grace for our planet. And it also represents a constant threat to all of us. And it is from us, our security depends on health, and, finally, a good mood in these hot summer days.
