Genes are the ones to blame why coffee doesn’t keep some people awake, recent study shows
According to scientific research, the body processes caffeine in a variety of ways depending on whether or not a person possesses a particular genetic variant that only some people have.
If you drink coffee in the morning, does it affect your ability to fall asleep at night, or does it not make a difference?
Have you ever pondered why people react differently to the effects of caffeine?
Researchers from Scotland have uncovered the secret behind why some people need coffee to get going in the morning while it has no effect on others.
This particular variant of the PDSS2 gene is only found in some individuals; other people do not have it. In addition, this gene influences the process by which the body breaks down caffeine, which in turn influences the amount of caffeine that is retained by the body.
Over a thousand respondents took part in the survey that was carried out in both the north and the south of Italy, while over 1,700 people participated in the poll in the Netherlands. All responders filled out a questionnaire in which they noted how much coffee they drank every day.
The researchers investigated this phenomenon and came to the following conclusion: people who drank less coffee also had some variants in the gene. Because it is broken down more slowly, caffeine remains in the body for a longer period of time and therefore keeps you awake for a longer period of time.
People who lack this gene, on the other hand, are need to consume coffee multiple times each day in order to feel its effects.
Your ability to retain caffeine is influenced not only by this gene, but also by other factors, such as your metabolism and whether or not you smoke.
If you are a smoker, then you will need to increase the amount of coffee that you consume. It is essential to take into consideration the quantity of coffee drank on a daily basis in addition to the potential adverse effects that coffee can have on the body. Reduce your intake of it if you notice that your heart is trembling or skipping beats as a result.
