Sleeping at night is a kind of rest for the body's physical activities during the day, and all organs of the body will detoxify during sleep, thus ensuring good health. Generally speaking, adults should fall asleep at least at 1 1, and sleep for 8 hours at 7: 00 in the morning, and the detoxification of organs such as liver, gallbladder and lung in the body is completed. From the perspective of Chinese medicine, midnight to 1 1 is the time for gallbladder activity, gallbladder detoxification, and so on. For a long time, all organs stay up late in turn, and toxins in the body accumulate in the body, which will drag down the physique, cause sub-health, and ultimately affect the vitality of the human body.
