This phrase was once widely circulated on WeChat. The phrase is derived from an expert quoting a line from the Yellow Emperor's Classic of Internal Medicine, which led to the idea that exercising at night is detrimental to health.
"Huang Di Nei Jing" in the original sentence is so said : Therefore, the yang qi one day and the main outside, Ping Dan yang qi ascending, the day in the middle of the yang qi rung, the day and night and the yang qi has been weak, qi door is closed, is why the twilight and collect, do not disturb the muscles and bones, do not see the fog and dew, against the three times, the form of the sleepy thin.
Broadly speaking, in the morning, the morning, Yang Qi began to gradually rise, at noon when people's Yang Qi is the most vigorous, the sun west of the Yang Qi becomes "weak", the pores are closed. So at night, the essence of the convergence, Yang collection, this time in the movement, it is easy to muscle congestion, viscera deficiency, people will be more and more powerless.
So this expert concludes that night exercise sweating will hurt the yang qi, meridians and bones, injuring the root of the person, the person will be more and more weak.
But what about the facts?
This passage from the Yellow Emperor's Classic of Internal Medicine, Knowledge is emphasizing the cyclical changes of yang qi in a person's day and suggesting that exercising in the morning may not make a person sleepy easily while exercising in the evening may make a person sleepy easily, and not mentioning that exercising in the evening is necessarily injurious to one's health.
The expert's interpretation can be described as "multiple interpretations".
In addition, things are constantly evolving, we have to use a dialectical, developmental perspective to look at this issue. As society continues to evolve, modern lifestyles, environments, and work schedules have changed dramatically, so we can't keep looking at things the same way we always have.
