The suicide rate of coffee drinkers is lower than that of non-coffee drinkers. Why does coffee have this effect?

This study, published in the World Journal of Biological Psychiatry, reviewed three large-scale health surveys in the United States, specifically a questionnaire survey every four years, which investigated people's consumption of coffee, caffeinated foods (tea, carbonated drinks and chocolate) and decaffeinated coffee. A total of 43,599 men and 65,438+064,825 women participated.

The study found that people who drink 2 to 4 cups of coffee a day (equivalent to 400 milligrams of caffeine) have a significantly lower suicide rate, only 50% of those who only drink 1 cup of coffee or decaffeinated coffee. But if you drink more than four cups, the suicide rate has not decreased.

Vitamin B family, bananas, dark chocolate, more sunshine, long-term non-sunshine will lead to depression, and you must eat a certain amount of carbohydrates every day to control your mood. The main reason for wanting to commit suicide is that life is unsatisfactory, you can't get what you want, and then you see too few or too many big waves. "In fact, generally speaking, bad luck lasts only three years. According to the China Book of Changes, these are the intangible cultural heritages of China. Take a look, it's been three years. Therefore, many people insist on suffering for three years and study hard for three years.

If you are already suffering, you will be lucky if you persist for another five years, so people say that "the wind and water turn around in thirty years", which is the truth. Researchers believe that this result can also be explained from the perspective of neurochemistry: caffeine has a similar structure to adenosine, a chemical in the human body. Caffeine, when ingested by human body, will combine with adenosine receptors in brain nerve cells. The combination of adenosine and its receptor will weaken the activity of nerve cells, but when the receptor is deceived by caffeine, the activity of nerve cells will not be inhibited and the human body will be excited. In addition, caffeine can also increase the contents of serotonin and glutamic acid, two important and pleasant neurotransmitters in human brain. Therefore, people always become excited and refreshed after drinking a large cup of coffee.
