China has advocated taking a nap since ancient times, just as Huangdi Neijing said: "The sun shines high at noon, and a nap is worth thousands of dollars." According to the theory of traditional Chinese medicine, the human body takes gallbladder meridian at midnight (at night 1 1 to the next morning 1), when yin is the most abundant, and then yang is born; At noon (1 1 o'clock to 1 o'clock), the heart meridian is taken, when the yang is the most abundant, and then it is cloudy.
At noon, the qi of heaven and earth changes. Don't disturb the qi of heaven and earth at this time, but have a good rest to cope with the constant changes.
Scientists from NASA also found that taking a nap for 24 minutes every day can improve work efficiency by 34% and brain sensitivity by 54%.
A study by a university in Athens found that people who take a 20-30-minute lunch break at least three times a week have a 37% lower chance of dying of heart disease.
Noon is the time when the heart meridian runs. At this time, the best way for the body is to let the heart rest, take a nap or sit still, but strenuous exercise and sweating will cause excessive damage to body fluids.
It is reported that a gym in Britain has set up a new "special fitness class" at noon: everyone does not do specific exercises during class, but takes a nap in bed for 45 minutes.
