Health preservation in early spring. Wu: "Spring Wu" is the most important rule of keeping in good health in spring. Although the cold in spring is not as cold as that in winter, if we don't pay attention to it, it is likely to further destroy the human body's defense function and lead to the occurrence or aggravation of diseases. Prevention: Chinese medicine believes that wind is the first of the six evils. If the wind is too strong, it will turn into a common cold, which is the length of all diseases and is easy to cause diseases and affect health. The wind is strong in spring, and "a hundred herbs sprout and all diseases recur" is a season that easily leads to the recurrence of old diseases. If you don't pay attention to health care, or eat too much spicy food to help the fire, and then it is triggered by a "cold" in spring, some old diseases will easily recur. Therefore, the key to keeping in good health in spring is windproof. Chinese medicine believes that there is an invisible "fire" in the body, which can generate warmth and strength and provide energy for life. Chinese medicine uses "fire" to describe some symptoms of heat in the body. If it is out of control, it will show symptoms, collectively referred to as "getting angry." To prevent "getting angry" in spring, we must first have a regular life, pay attention to the combination of work and rest, and rest on time. Secondly, eat more fruits and vegetables and avoid spicy food. Drink plenty of water or heat-clearing drinks to promote the excretion of "pyrogenic substances" in urine and sweat.
