In winter, going out of the room as a living "sunflower", often supplementing warm sunshine and taking part in some fitness activities are very beneficial to sterilization, disease prevention, health care and physical fitness. It can be said that it is a cost-free health care method.

The sun is called "the biggest sterilizer". The ultraviolet rays of sunlight are a kind of "natural disinfectant". If we can do "three basking"-drying clothes, bedding and people, we can greatly reduce the incidence of various respiratory infectious diseases. Often basking in the sun in winter can increase the body surface temperature, promote blood vessel dilation and lower blood pressure.

In addition, moderate ultraviolet radiation can produce a kind of "sunshine hormone"-vitamin D3 in the body. The interaction between vitamin D3 and calcium can control blood pressure, and sun exposure is beneficial to heart health. Studies have proved that vitamin D deficiency is an independent risk factor of heart disease.

Extended data

Benefits of sunbathing:

1, prolong life.

Since 1980, Danish researchers have studied 4.4 million Danmai people for 26 years, and found that more sunshine can prolong their life. Swedish research also found that compared with women who sunbathe in summer, the death rate of women who do not sunbathe is twice as high. Inge Henshipp Clemmensen of the Danish Cancer Institute believes that people who spend a long time in the sun go outdoors more often than those who always stay at home or in the office, which is also an important reason why sunshine is good for health.

2 is beneficial to lowering blood pressure.

Hypertension often occurs in winter and in areas far from the equator. An article published in the journal of Dermatology Research 20 14 gives a possible explanation: sunlight can make nitric oxide in the skin absorbed by the blood, thus helping to lower blood pressure. Dr. Martin Fri?, a professor of experimental medicine at the University of Warwick in the UK, who participated in this research, believes that this research has made the benefits of sun exposure go beyond the scope of beneficial vitamin D supplementation.

3. Reduce the risk of breast cancer.

A report published in the journal Environment and Health Outlook said that exposure to sunlight may reduce the incidence of breast cancer. For 10 years, women who engage in outdoor activities at least 1 hour every day have a lower risk of breast cancer than women who engage in outdoor activities less than 1 hour every day.
