A healthy heart and blood vessels form the basis for proper functioning of the human body. Not just good food and good living, but also the sun can positively affect the cardiovascular system.

In winter, especially in northern latitudes, increasing the number of cases of heart failure, heart attack or stroke. "This is caused by solar radiation penetrates to the ground through a much thicker layer of the atmosphere. When it loses a large proportion of ultraviolet radiation which triggers the formation of a signaling molecule nitric oxide in our skin. It is therefore advisable in winter the sun's rays to supplement adequate visits to tanning beds, "said Michal Kárych, chairman of the Czech Association of healthy tanning, which deals with the effects of UV radiation on human health.

Numerous studies additionally demonstrates that moderate exposure to sunlight is not only beneficial for the cardiovascular system, but also overall health. In addition to improving blood circulation and reduce high blood pressure, the sun's rays can also contribute to a decrease in cholesterol and blood sugar.
