To maintain good health during the Spring Festival, in addition to eating healthily, daily routines and exercise are equally important. Zhang Jin, a member of the Agricultural and Labor Party and director of the Preventive Medicine Center at Xiyuan Hospital of the Chinese Academy of Traditional Chinese Medicine, believes that during the Spring Festival, health preservation should not only prevent the invasion of cold air, but also focus on how to avoid the occurrence of internal heat. Some people may dress too thickly because they are afraid of the cold. Although this practice can block the cold outside, it can also lead to difficulty in dissipating internal heat, resulting in a state of internal heat accumulation. Especially in dry and cold winter, the external environment can easily make people restless, leading to problems such as heart fire and liver fire Zhang Jin stated. Once internal heat is generated, the body needs to dissipate heat in some way, and sweating is a common pathway, which also requires attention to timing and methods. Zhang Jin reminds: "It is best for fever patients not to rely on sweating to cool down, otherwise it may easily lead to sagging of the skin's pores, making it easier for the skin's surface to sweat and causing cold air to invade the body. Moderate exercise is a better choice for" heat dissipation ". Traditional Chinese medicine advocates' light labor ', which refers to the exercise method that avoids excessive sweating and fatigue. "Zhang Jin explained," Excessive sweating can take away Yang energy and body fluids from the body, so the intensity of exercise should be controlled at a slightly feverish level. Soft forms of exercise such as the Yi Jin Jing and Ba Duan Jin can be practiced to stretch muscles and remove bones. "Joint damage is a common phenomenon during winter exercise. Zhang Jin suggests that during the warm-up phase before exercise, special attention should be paid to joint activity. "After waking up in the morning during holidays, you can sit by the bed and gently pat the limbs and joints of the body, without emphasizing certain joints or parts. This' patting 'can allow our own qi to promote blood circulation, putting the body in a state of full body massage, awakening the body, mobilizing yang energy in the body, and preparing for the day's activities." "Going to bed early and getting up late" is also very beneficial for mobilizing yang energy. Zi Shi is a crucial moment for the alternation of yin and yang, and only when yang energy enters yin can one sleep soundly, "Zhang Jin shared. Especially during the Spring Festival holiday, people tend to stay up late for entertainment. If Zi Shi has not yet gone to sleep, yang energy will remain on the surface of the body, not only causing internal heat, but also consuming body fluids, leading to excessive fatigue. (New Society)
