What are the benefits of a nap?

At noon, the largest blood flow to the heart belongs to the meridian - heart meridian, at this time is the heart meridian "duty", it is the most vigorous blood, and the heart meridian is to regulate and improve the function of the heart is the best "long arm of the tentacle". Traditional Chinese Medicine (TCM) emphasizes "the harmony of heaven and man, the unity of man and heaven, the law of yin and yang, and the law of nature," meaning that one should adjust one's life in response to the changes in heaven and earth, in order to "go with the flow" of nature.

At night, Zi Hour and noon, it is the point of transition between yin and yang of heaven and earth, the time of "merging yin" and "merging yang", the time of yin and yang assembly, and the time of the interplay of fire and water. The human body must also pay attention to this point of transition and rest and recuperate, so as to allow the body to conform to the changes in the qi of heaven and earth. The ancients called taking a nap "stealing the vitality of heaven and earth", which is the most brilliant and scientific wisdom of health care.

However, Dr. Raphael Pirejo, a clinical professor at the Center for Sleep Medicine at Stanford University School of Medicine, completed a study on the psychology of sleep that found a direct correlation between sleepiness and changes in body temperature. When the body temperature drops, the body thinks "it's time for the body to relax". In the "1:00 p.m. to 4:00 p.m." and "11:00 p.m. to 7:00 p.m. the next day," the body's temperature is relatively low, so the best time to take a nap should be from 1:00 p.m. to 4:00 p.m. Scientists warn that a late nap can lead to difficulty in falling asleep at night or even insomnia.
