Sunbathing can prevent myopia: one of the reasons for myopia may be related to lack of sunlight. Because sunlight can stimulate the production of dopamine, so as to prevent the focus of light entering the eyes from being distorted when focusing. Therefore, regular exposure to the sun can reduce the risk of myopia.

Sunbathing can prolong life: after 26 years of research, experts have found that people who stay in the sun for a long time live longer than others.

Lack of sunshine leads to depression: Studies have found that in winter or rainy weather, some people will have symptoms such as insomnia, chest tightness and irritability, which are all caused by the reduction of sunshine time.

Sunbathing can enhance immunity: Studies have confirmed that normal viscera functions in the human body are basically supported by yang. If the yang in the human body is sufficient, the ability to resist diseases is high. Sunbathing can not only keep fit, but also enhance people's immunity.
