Spring belongs to wood, liver belongs to wood. It is reasonable to pay attention to nourishing the liver in spring health preservation. Then nourishing the liver in spring should follow the way of "lying late and getting up early", rather than going to bed early and getting up early as people often say. It is still a word "shun". Shun is the gas of spring hair growth. Because spring is full of vitality, the length of day and night has changed, the days are long and the nights are short, so the working hours during the day can be moderately extended and the sleep time at night can be moderately shortened. It may sound a little confusing, but in order to stay healthy, it is necessary to extend working hours. Actually, that's it. For example, when water is in a half tank, shaking it will produce great force on the collision of the tank wall. When the water is full, not only will there be no tinkling when the can is half full, but the impact on the can wall will also be much weakened, and even if the eggs are put in, there will be no damage.
In spring, everything comes back to life. When we treat our bodies, we should help them grow up like new things without hurting them. In a sense, a moderate extension of working hours is a way to "replenish water" to the body and prevent it from being shocked by the breath of spring, so a moderate extension of working hours has actually become a kind of maintenance and gives the body a chance to grow. If you violate this principle, it will hurt your liver and qi. Cold pathological changes will appear in summer, which will make people adapt to the lack of energy in summer. This can also be explained by the principle of coexistence of five elements. Spring belongs to wood, summer belongs to fire, and wood can make a fire. If the wood is not well maintained now, it will affect the fire in the next stage. Once the fire is weak, it will cause cold damage. So if you didn't take good care of yourself last season, the accumulated illness will show up in the next season. This is the way to keep "life" in line with spring, so get up early and go to bed late.
