Drink coffee or tea should be a small number of times
Some people need to work at night because of their careers. In order to dispel drowsiness, people are used to drinking coffee or tea to keep themselves awake. For this reason, some people drink a large cup of coffee or tea at a time. In fact, I am afraid they do not know that this is not a good way to stay awake. If you want to give full play to the role of caffeine in tea or coffee, you should drink coffee or tea a few times. This is the conclusion of James Wyatt, an expert on sleep at Luhe University in Chicago, who published their findings in the latest issue of the American Journal of Sleep.
James Wyatt and others found 16 volunteers to do the experiment and asked them not to sleep for 28.5 hours. For the convenience of the experiment, instead of giving them coffee, they were given pills containing a precise amount of caffeine. It turned out that people who swallowed a small amount of pills but many times were more likely to stay clear than those who swallowed a lot of pills at once, and their natural sleep system was not disturbed.
James Wyatt and others put forward a theoretical explanation for this phenomenon. They point out that people want to sleep because the body secretes a substance that causes people's desire to sleep at regular intervals, and caffeine suppresses the effect of this substance. But caffeine is most effective only when caffeine is present at the same time as the substance. So you can't drink a lot of coffee at one time, but drink a small amount of coffee many times.
