How much do you know about "coffee time"? Health knowledge of Coffee

Having a cup of coffee in the morning may be something many white-collar workers often do, but do you know? If you drink coffee as the first thing to do every morning, you will weaken the refreshing effect of caffeine and may lead to an increase in your tolerance to this irritant.

Of course, everyone's physical condition is different, but our bodies are all affected by the hormonal cycle, which is the biological clock. These basic biological rhythms are pre-programmed in our genes, and although our habits can disrupt the physiological cycle, the main factor that regulates the biological clock is sunlight. There are many things that are controlled by the biological clock, one of which is a hormone called cortisol, which makes us more alert and refreshing. That's why. Cortisol levels normally peak between 8am and 9am, when many people are drinking the first cup of coffee of the day on their way to work. In fact, their bodies are producing caffeine most effectively. Caffeine intake during peak cortisol production actually reduces the effectiveness of additional stimuli. To make matters worse, by consuming caffeine when you don't need it, your body will develop tolerance to caffeine more quickly and your pick-me-up effect will be greatly reduced.

Cortisol is also thought to be a stress-related hormone, and studies have shown that caffeine intake at the highest cortisol levels increases cortisol production. Therefore, increased caffeine tolerance may lead to higher levels of cortisol in the body, which can disrupt the circadian rhythm and have other harmful effects on health.

The best time to drink coffee-to get the most enjoyment while minimizing the negative effects. For most people, cortisol levels peak between 8 a.m. and 9 a.m., 12:00 to 1 p.m., and 05:30 to 06:30 Therefore, your "coffee time" (which is the right word) should be scheduled from 09:30 to 11:30 and from 01:30 to 5 p.m., so you can take advantage of lower cortisol levels, when you need a pick-me-up most.

These theories sometimes sound against people's normal habits, but this is really the conclusion proved by scientific research, have you mastered your "coffee time"?
