The impact of solar radiation on the quality of rest

man, as you know, was the result of an evolutionary process in warm regions where the total amount of solar radiation is quite large.Undoubtedly, the sun's rays in moderation by skin have only a positive impact on human health and contribute to a significant improvement in the quality of rest.The impact of solar radiation on human is to stimulate many important metabolic processes, activating the body's defenses, improve adaptation to specific environmental conditions.Under the action of sunlight on our skin it forms vitamin D, which provides normal regulation of metabolism of calcium and phosphorus in the body and prevents the development of such dangerous diseases such as rickets.The dark color of the skin of the indigenous African population is a kind of protection from the excessive amount of solar radiation, and the light skin of residents of the northern hemisphere, on the contrary, is adapted to capture more ultraviolet rays (as in the northern latitudes of the earth's surface receives a smaller

amount of solar radiation).

As already noted, the sun's rays are not only not dangerous to humans, but also help to improve the quality of his rest, providing a positive impact on many organ systems of the body.However, this does not mean that solar radiation - completely harmless thing.For example, strong lighting, which affects our bodies in the long-term concentration of view of the bright sun, can lead to the destruction of the visual pigment and cause blurred vision.At high altitude indicated an increased exposure to UV rays.Therefore, if you are going to spend your holidays, riding in the mountains to ski, then you definitely need protective eyewear that will protect your eyes from the negative effects of solar radiation.

In addition, with a long stay in the open air on a hot summer day, there is a danger of sunstroke.To prevent the occurrence of this condition is necessary to wear a hat - a hat, cap or an easy scarf.

In rare cases, people may occur one more pathological reaction of the organism when exposed to solar radiation.In this case, even if the short-term and minor skin contact of sunlight on the skin rash, severe itching, dizziness and headaches.It is clear that people with similar pathological reactions uncontrolled effects of solar radiation can significantly worsen health, not to mention that the quality of rest in this case will inevitably decline.

Thus, the influence of solar radiation can both significantly improve and reduce the quality of your vacation while on vacation.Spending free time in the open, do not forget to pay attention to the intensity of solar radiation at the moment.If you decide to sunbathe, it is best for this procedure to choose morning or evening hours (at this time the solar radiation is not harmful to health).
