Conducted by researchers from Edinburgh University study found that exposure to daylight can reduce the risk of human stroke and heart attack. As it turned out, the ultraviolet rays release compound that helps lower blood pressure, which in turn is a positive factor in the prevention of these diseases.
The study involved 24 people. Scientists studied their pressure, and then subjected volunteers to the effect of infrared lamps and ultraviolet rays. Analyses of the results found that in the time of exposure to UV-radiation blood pressure of the participants was reduced.
