Why is coffee so refreshing?
Coffee has become a life-sustaining artifact for contemporary people. Sleepy in the afternoon? have a drink! Unhappy mood? have a drink! So do you know why coffee is so refreshing? Why are some people still sleepy after drinking coffee? Will it hurt to drink too much? Come and chat today.
1.Why is coffee so refreshing?
This starts with why we get tired. When we do not rest for a long time, a substance called “adenosine” will be produced in the body. This substance can bind to adenosine receptors in the brain. After the combination of the two, a series of reactions will occur, which will be transmitted to the brain. The message of fatigue, resulting in a feeling of fatigue and sleepiness.
The reason why drinking coffee can be “refreshing” is because the chemical structure of caffeine in coffee is similar to adenosine. When the brain cannot receive the signal of fatigue, we will not feel tired, thus playing a “refreshing” role.
In layman’s terms, caffeine does not eliminate physical fatigue, but only temporarily “deceives” the brain, blocking the signal of physical fatigue, not producing fatigue in a short period of time, and playing a “refreshing” role. When the caffeine runs out, the fatigue comes back. So if you want to stay energetic, you still have to pay attention to the combination of work and rest, and don’t rely too much on the “refreshing” effect of coffee.
In addition to refreshing, coffee can also give us pleasure. Experiments have shown that the aroma components of coffee can significantly increase blood flow in the hypothalamus of the brain, which is the area of the right brain that produces pleasure, which is why coffee is so popular.
- Why are some people unable to refresh themselves when they drink coffee?
Some people say that after drinking coffee, instead of being awake, I am even more sleepy. Why is this? There are mainly the following reasons:
Drink late – when adenosine and receptors are already bound, there is little point in caffeine stopping them at this point.
Drink too much – Regular coffee drinking produces antibodies that block the refreshing effect of caffeine. Just like regular drinking can lead to resistance to alcohol, and regular consumption of a drug can lead to drug resistance.
Drink too much – Regular coffee drinking produces antibodies that block the refreshing effect of caffeine. Just like regular drinking can lead to resistance to alcohol, and regular consumption of a drug can lead to drug resistance.
Fast metabolism – some people have a naturally strong metabolic function, and no matter how much coffee they drink, they will be quickly excreted from the body. For such friends, drinking coffee can be understood as “quenching thirst”.
Coffee is bitter with acid, sour with softness, soft with alcohol, and alcohol with sweetness. Drinking in moderation is good for health. But if you can’t live without coffee every day, or even have several cups a day, will it hurt your health?
3.Will it hurt to live on coffee?
Does not cause cancer – There is currently insufficient evidence that drinking coffee increases the risk of cancer in humans.
Does not cause heart disease – healthy adults drink coffee in moderation (1-2 cups per day)
Does not increase the risk of heart disease and cardiovascular disease.
However, some people who are sensitive to caffeine may experience discomfort such as rapid heartbeat/nausea/dizziness. In such cases, it is recommended to adjust the amount of drinking.
Having said that, in order to make a cup of mellow and refreshing coffee, of course, the blessing of the coffee machine is inseparable.
