Staying up late will certainly affect height, generally staying up late most people will not sleep after 11 p.m. This is the time when two important organs of the human body need to rest and get energy replenishment. Chinese medicine believes that 11:00 pm to 1:00 am, is the time of the foot Shaoyang bile meridian circulation; 1:00 am to 3:00 am, is the time of the foot Convulsive Yin liver meridian circulation, liver, gall bladder as the functional state of two important organs of Chinese medicine, is the main blood collection, the main drainage, but also the main tendons, joints. The tendons and veins here are mainly the body’s ligaments, so between 11 p.m. and 3 a.m., rest and energy replenishment of the liver and gallbladder meridians are needed. If energy is not replenished effectively at this time, and the liver and gallbladder meridians are not effectively rested, the function of blood collection and drainage will be affected. The liver’s function of blood collection has an important role in moisturizing the body’s tendons and veins, or ligaments. If the ligaments are well energized, development will be sound and it will be helpful for the growth of bones. If the liver’s function of collecting blood decreases and there is not enough blood, the ligaments will also be affected, which will affect the development of bones. At the same time, the growth and development of bones and the kidneys are also related, because the kidneys are the main reservoir of essence, the kidneys are the main bone marrow, can produce bone marrow, bone marrow production is sufficient, the growth of bones will be sound, so the kidney’s function of reservoir of essence is also very important. In Chinese medicine, it is said that the liver and kidney are of the same origin and the essence and blood are of the same origin, so the normal function of the kidney is related to the function of the liver. If the liver’s blood collection function is normal and blood is sufficient, the bone marrow and kidney essence will also be sufficient, and the bone marrow will have a constant source of production. Staying up late will affect the liver and also the kidney’s essence, so it will affect the growth and development of the bone, so staying up late will definitely affect the height, you should pay attention to maintain a reasonable and scientific sleep time to avoid damage to the human liver and kidneys.
