Coffee studies whether coffee can effectively relieve drowsiness

If you want to wake up and doze off, a cup of coffee is certainly not enough. The amount of a cup of coffee can only reach the level of relaxation, but it makes people feel drowsy. The saying that "coffee can wake up effectively" is only when everyone has not yet adapted to it.

After lunch, people always feel bothered by drowsiness. In order to wake up sleepy, there are not a few office workers who wake up dozing off while working in the afternoon. For some people who often write all night, coffee is an indispensable item. But can coffee really have the effect of waking up and sleepy?

How effective is coffee in the fight against Sandman? Japanese food expert Yajun Kato said: "if you want to wake up and doze off, the amount of a cup of coffee is definitely not enough." The amount of a cup of coffee can only reach the level of relaxation, but it makes people feel drowsy. The saying that coffee is an effective awakening can only happen when no one is used to coffee and has no immunity to caffeine. "

Of course, immunity to caffeine varies from person to person, but according to research, it is impossible to achieve the goal of "awakening" without four cups of espresso.

"but it should be noted that even a small amount of caffeine can make them react obviously to people and children who don't drink coffee very much. In addition, caffeine has an irritating effect on the stomach, so it's best not to drink too much on an empty stomach. If you really want to achieve the goal of 'awakening', you might as well drink more cocoa powder rich in cocoa. "

Cocoa, the raw material of cocoa powder, contains theobromine, which keeps the human body excited. Unlike caffeine, theobromine doesn't have a good diuretic effect, so it doesn't make running to the toilet a culprit that interrupts attention at work. Therefore, for people who want to work all night, a cup of hot is a better choice than coffee.

But Yajun Kato also said: "drinking coffee after a meal is a good habit for your health." Because the catechins and tannins that keep the bitter taste of coffee can effectively inhibit the activity of neutral fat and achieve the effect of losing weight. "

Rather than using coffee to awaken drowsiness, it may be more right to enjoy a relaxing moment in your tired work and life.
