Six taboos for drinking coffee refresh or deceive yourself

First, do not drink a lot of coffee in a short period of time in order to refresh yourself, which is equivalent to drinking a lot of stimulants, which may lead to heart disease.

Second, do not drink coffee immediately after drinking, otherwise it will accelerate the dehydration of the body and is more likely to cause high blood pressure.

Third, if you drink coffee, try to choose something light, do not drink too strong coffee, strong coffee will make people more dry, and reduce people's judgment and understanding ability.

Fourth, do not drink coffee continuously for a long time, because drinking coffee is also addictive, once you continue to drink coffee for too long, you will have a certain dependence on it, which is also a negative effect on the spirit.

Fifth, when getting married, the man had better drink less coffee, because substances containing caffeine will do some harm to sperm. (it doesn't hurt to drink less, but drinking too much will have a certain effect on reproductive function.)

Sixth, remember not to drink coffee on an empty stomach, because it is more irritating to the intestines and stomach, especially to people with gastrointestinal problems. (usually drink coffee with the right amount of cream, which can protect the intestines and stomach.)

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.
