Scientists have shown that UV radiation protects the heart by contributing to the release of natural sources of nitric oxide in our skin. It regulates blood pressure, dilates blood vessels and promotes blood flow to the heart.
A team of scientists led by dermatologist Richard Weller confirmed that lack of sunlight is bad for the heart and blood vessels. 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. Sun is able to alter cholesterol and ergosterol found in the fat glands under the skin of vitamin D. "It is important for the absorption of calcium in bones and prevent osteoporosis. For a daily dose of vitamin D we need at least 10-30 minutes in the sun every day, "said Michal Kárych of the Czech Association of healthy sunbathing.
