Refreshing yourself with coffee? You're just deceiving your body.
Many people are used to drinking coffee because it is refreshing. In fact, its pick-me-up effect is not as good as everyone thought.
There are no less than hundreds of ingredients in coffee. Among them, caffeine is undoubtedly the most important, and many people attribute coffee's boost to caffeine. Although there is decaffeinated coffee, for most coffee lovers, it is not "real" coffee at all.
In theory, caffeine does have a refreshing effect. When people don't have a rest for a long time, they naturally feel tired and tired. When the body is tired, it tells the brain through a signaling substance called adenosine. And the more tired the body, the more this substance.
But for the brain to know, "I'm tired," you have to dock the substance with a particular receptor in the brain. The caffeine in coffee can also bind to this receptor-and block the messenger, which is equivalent to blocking the normal binding of other receptors. In this way, the brain will not be able to receive signals from fatigue materials, and it will not feel tired, and it can carry it for 4 to 6 hours to have a "refreshing" effect. However, the amount of adenosine that makes people feel tired has not decreased. So caffeine is just a way to cheat the body. (Kexin Food and Nutrition Information Exchange Center Nguang Guangfeng)
