Why do some people drink coffee without insomnia?

The most desperate experience of drinking coffee is that you are still sleepy after drinking it, but you can't sleep even after counting 100,000 sheep at night. And the happiest experience of drinking coffee must be that you can still fall asleep when you lie in bed. The furthest distance between people may be that you are so sleepy that you drink coffee and I can't sleep when I drink coffee.

Why do some people drink coffee like drinking water, while others can't sleep until dawn?

The ➤ gene determines your ability to break down caffeine

Scientists have found that there is a gene called PDSS2 in the body that affects the ability of cells to break down caffeine. A British professor proved the relationship between genes and caffeine metabolism through experiments.

The team studied the genetic information of 1213 Italians and 1731 Dutch. They found a negative correlation between the PDSS2 gene and the body's ability to break down coffee. When the protein level of PDSS2 gene expression is low, the enzymes involved in caffeine metabolism become active, so that caffeine can be broken down normally. When the protein level of PDSS2 gene is high, the enzymes involved in caffeine metabolism will be inhibited, thus hindering the decomposition of caffeine.

In other words, people who drink coffee without insomnia may have a weak PDSS2 gene, which causes the body to consume caffeine so quickly that it doesn't count so many sheep at night.

➤ habits determine your tolerance to caffeine

People who rarely drink coffee may lose sleep until three or four o'clock after drinking a cup of mocha, while long-term coffee drinkers may need several cups a day to stay excited.

Usually, the refreshing effect of a cup of coffee can last for 4-6 hours. If you drink in the morning, the effect of caffeine will fade and disappear in the afternoon, while if you drink it in the evening, the feeling of "beating chicken blood" will last until late at night.

For people who are used to drinking coffee, one cup is not even refreshing enough, of course, there will be no insomnia.

➤ psychological suggestion may prolong the action time of caffeine.

"I had coffee today, and I can't sleep at night."

Once there is such a psychological hint, 99% of people will get what they want-they can't sleep. And whenever there is insomnia, the brain falls into a cycle that the more you want to sleep, the more you can't sleep. People with such psychological cues are usually caffeine-intolerant receptors that can be tossed over and over until dawn in one cup. People who do not have insomnia are caffeine-tolerant receptors themselves, so they are not affected by psychological cues.

So, even if you drink an occasional cup of coffee, don't give your brain a conscious signal that you can't sleep; try to relax your brain and it may be easier to fall asleep.
