Scientists have identified the harm and benefit of cold

During freezing weather, we rarely want to leave a warm room and go outside. However, scientists from Harvard University, USA, who compared the danger of cold and heat, recommend not to neglect winter walks

Scientists have shown that excessively warm weather is fraught with 5 times more risk to the human body than cold. According to their observation in the winter cold air contains 30% more oxygen than in the summer heat. At sub-zero temperatures, bacteria and microbes do not survive, and fresh snow perfectly filters the air from urban dust.

Beauticians recommend walking in the frost to improve the complexion and skin circulation. According to doctors, cold is effective for the treatment of neurotic and depressive states, and it also has a positive effect on immunity. The frosty air is a stress for the organism, therefore, as a response, blood circulation is accelerated and immunity is activated.

Scientists have proven that walking in the frost also has a positive effect on the cardiovascular system and promotes the burning of cholesterol.

A kind of color therapy works and monitoring of snow fell. At this time, serotonin is produced - the hormone of happiness, which reduces the negative impact of negative emotions.

The researchers found that when the frost is below -5 ° C, the person feels less pain, so winter walks are shown to migraine sufferers.

Fresh frosty air allows you to quickly recover from overwork, even a few minutes on the balcony is enough to mental stress after a working day is gone.

Doctors recommend using cold days for walking and restoring health, but at the same time take all measures to prevent frostbite. The risks of hypothermia and frostbite of hands, feet and face are considered by the physicians to be the only negative effects of cold weather.
