Coffee, in the past, has always been the favorite drink of Westerners, just like the importance of tea to Chinese, but now more and more people like coffee, so why is coffee so bitter that people love to drink it more and more? Next, I will introduce you to some of the benefits of coffee, and after reading it, you will understand why coffee is loved by people.

1. Drinking coffee can eliminate fatigue, I believe this benefit is the reason why everyone drinks coffee, if we are sleepy and tired, drink a cup of coffee, this is because coffee is rich in caffeine, and caffeine has the effect of eliminating fatigue and stimulating nerves, so it is best not to drink coffee at night, otherwise it will affect sleep.

2. Drinking coffee regularly has the effect of reducing the risk of chronic diseases, and now there are more and more studies showing that drinking coffee can reduce the risk of Alzheimer's disease, Parkinson's disease and diabetes.

3. The reason why young people are more and more inclined to coffee nowadays is not because coffee is qualified, but because in the fast-paced modern society, poor young people simply don't have time to sit down and savor a cup of tea. Caffeine can only be replenished quickly and cheaply with coffee to give our lives a chicken blood.

Theoretically, caffeine does have some effect on a pick-me-up. When people don't rest for a long time, it is natural to feel tired. When the body is tired, it tells the brain through a signaling substance called adenosine that the more tired the body, the more this substance will be.

But for the brain to know that "I'm tired," the substance must be connected to a specific receptor in the brain, and the caffeine in coffee binds to that receptor — and blocks the delivery of messengers, which is equivalent to blocking the normal binding of other receptors.

In this way, the brain will not be able to know the signals transmitted by the fatigue substance, and it will not feel tired, and it can be carried for 4-6 hours, which has a "refreshing" effect.

In fact, there are many reasons why different people drink coffee differently. First and foremost, the reason is genetics. Because of the genetic relationship, the receptors in the brain are different for each person.

Some people's brains are better able to receive caffeine, and the effects of coffee are especially pronounced in these people.

Second, the difference caused by age. As we age, there are fewer receptors in the brain that can dock with caffeine. A 60-year-old person has less than a third of the receptors in the brain of a 20-year-old, so the effect of coffee on the elderly is often smaller.

Thirdly, differences in diet and lifestyle habits can also have a big impact. If you drink a lot of coffee for a long time, the brain will release fewer and fewer receptors, and because of habit, the effect of coffee will become less and less.

Therefore, everyone's reaction to coffee is also different.

Drinking coffee is sure to be a pick-me-up.
