Exercise properly and keep warm during exercise to adapt to spring. In spring, we should pay attention to a happy mood and avoid getting angry, so as to maintain the normal growth and regulation of liver qi, so as to avoid damaging liver qi and suffering from cold diseases such as colds and coughs. The temperature changes greatly in early spring, so don't take off your cotton-padded clothes too early, but take them off later, and reduce them one by one, especially pay attention to the warmth of your lower limbs. In spring, the temperature difference is big, the wind and sand are big, and the spring rain is little. Old people and children should pay attention to prevent colds, so as not to be infected with hepatitis without proper treatment and protection. In spring, the liver is full of qi and the temper is weak. Because sour taste belongs to the liver and sweet taste belongs to the spleen, we should eat less sour and more sweet.
