Research points out that emotions have a great impact on our health, and “emotional flu” can have a negative impact on the body’s vegetative nerves, thus affecting the endocrine system and immune system and causing a sharp drop in immunity over a period of time. Reconciling and relieving emotions is an important aspect of our health, first of all, we should try to avoid emotional impulses, to achieve emotional stability and optimism. At the same time, we can do some research in adjusting our diet: for example, eat more food with high protein at breakfast, and more food with high carbohydrate at dinner, because carbohydrate food has a sedative effect, this way of eating is the opposite of the regular meal combination. Eat more fruits and consume less meat. The normal environment of the human body is weak alkaline, eat more meat, the body shows an acidic state, and stress and bad emotions also produce acid, it will affect the normal work of a variety of neurotransmitters. Vegetables and fruits are alkaline substances, eat more to facilitate the acid-alkaline balance, for the health of the body. Secondly, it is advisable to be cautious in life, try not to stay up late, work and rest should be regular, not too strenuous, such as sleeping on time, to maintain adequate rest. Sleep is the essential basis for the nervous system to relax and rest, and when you have free time, you can do some sports, such as yoga, ball games, running, etc., to make comprehensive adjustments in thought, diet and rest, to avoid stress “erosion” of our body, and to try to alleviate the deterioration of their own emotions in the dry climate of spring.
