Depression has become the fourth major disease threatening human health, and its prevalence is on the rise. It is predicted that by 2020, depression may become the second largest disease after heart disease. Depression has become an unavoidable topic.
water, a natural antidepressant
Depression is a mental illness characterized by significant and lasting depression, and lack of serotonin is one of the main characteristics of depression. The mechanism of action of many antidepressants is to slow down the degradation of serotonin and prolong the effect of serotonin on The duration of action of nerve endings.
To synthesize serotonin, an amino acid, tryptophan, is indispensable. Drinking plenty of water can maintain a stable supply of tryptophan in the brain tissue in various direct or indirect ways, thereby preventing the lack of serotonin.
When the human body is in a dehydrated state, it cannot form enough urine to effectively discharge the metabolic waste products in the body and the acidic substances in the cells. In order to neutralize the acidity in cells, the human body needs to decompose some amino acids to maintain an alkaline internal environment. Drinking a lot of water can not only fully discharge the metabolic waste in the body, but also automatically maintain the acid-base balance in the cells, thereby saving valuable amino acids, including tryptophan, and effectively preventing depression.
Any substance that enters the brain through the blood-brain barrier requires a special delivery system. Tryptophan and the other 5 amino acids use the same delivery system. Under dehydration, the concentration of other amino acids will increase, which will occupy the available space in the delivery system and reduce the supply of tryptophan in the brain.
Water not only generates heat to help tryptophan pass through the blood-brain barrier, but also accelerates the process of tryptophan entering brain cells through a series of indirect effects.
