People know from childhood that there is no life without the Sun. A sunny day brightens the mood, increases activity, and metabolism in the body.
However, the high temperature affects the human health. Excessive ultraviolet rays can cause irreparable damage to the body. Sunburn not only affects the outer layer of the body, but also damages the eyes. The risk of sunstroke increases in the summer. Thus, physicians advise everyone not to walk during the day between 09:00 and 18:00.
