Drinking coffee keeps people awake? Indeed, the caffeine in the coffee drives away drowsiness, especially a cup of black coffee before going to work, which is as refreshing as the first ray of sunshine that enters the house in the morning. However, if you think this effect is not good enough, you might as well try to get some sleep immediately after drinking coffee, as long as it takes less than 20 minutes, which is more refreshing and energetic.

But doesn't caffeine keep people awake? Tasting Table reports that adenosine, a hormone in the body, is secreted when people are working and active, which makes people feel tired, while sleep reduces secretion. So taking a nap immediately after drinking coffee not only reduces adenosine, caffeine does not have to make much effort to fight drowsiness, but also takes advantage of the opportunity to block the tired receptors of the human body, greatly increasing the refreshing effect.

In addition, don't forget to sleep for 15 to 20 minutes, otherwise the effect will not be so good. Because if you sleep longer, the brain goes to a deeper sleep and wakes up with more effort to wake up. And caffeine starts to work about 20 minutes after drinking it.

Although scientists have not yet observed the effect of napping on the brain after drinking coffee, they have done experiments to show that coffee combined with napping is more refreshing than simply napping or drinking coffee.

An experiment at the University of Loughborough (Loughborough University) in the UK asked tired subjects to take a nap after drinking coffee and then let them drive in a virtual situation, Vox reported. The results showed that the combination of drinking coffee and then going to bed reduced the subjects' mistakes while driving compared to drinking coffee, sleeping or taking a decaf placebo. And it's also effective for people with sleep disorders.

In another Japanese experiment, subjects performed a series of memory tests and found that those who drank coffee and then took a nap performed better than those who took a nap, washed their face after a nap or shone their eyes with bright light after a nap. They themselves feel less tired.

Of course, in theory, drinks containing caffeine can work, common tea is a kind of tea, but generally speaking, the caffeine content of tea is low, the effect is not strong.

Finally, if you want to try this pick-me-up idea, remember the following points:

Drink fast in order to get enough sleep.

If drinking hot coffee quickly is too hot, you can choose iced coffee or espresso.

Take a nap immediately after drinking. Don't worry that you can't sleep. Even if you are half asleep and half awake, as long as you reach a calm state, it will help.

Finally, remember to wake up within 20 minutes so that you don't go into a deeper sleep and get caffeine to work in time.
