Is drinking coffee definitely refreshing? the refreshing effect of drinking coffee varies from person to person.
Can drinking coffee cheer you up?
The refreshing substance of coffee is caffeine. Caffeine can act on the cortical layer of the central nervous system, improve people's attention and association ability, thus reduce fatigue, and really have a refreshing effect.
Second, why can't some people refresh themselves by drinking coffee
How can some people refresh themselves by drinking coffee while others still feel sleepy? There are three factors that cause coffee to have different effects on people: age, genes and habits:
1. Age factor:
With age, there are fewer and fewer receptors in the brain that can dock with caffeine. The number of receptors in the brain of a 60-year-old is less than 1/3 of that of a 20-year-old-so coffee tends to have less effect on the elderly.
two。 Genetic factors:
Everyone has different receptors in the brain because of their genes. Some people's brains are better able to accept caffeine-coffee has a particularly significant effect on these people.
3. Habitual factors:
If you drink a lot of coffee over a long period of time, the brain will release fewer and fewer receptors-coffee will have less and less effect because of habit, which is similar to producing immunity.
