Coffee has a greater impact on men.

Coffee drinkers around the world know that drinking coffee can wake people up, but they certainly don't know that it only takes 10 minutes for coffee to work, the Daily Mail reported.

Researchers at the University of Barcelona have found that caffeine has an almost immediate effect on the body after drinking coffee. In the past, scientists have found that after drinking coffee for nearly an hour, they begin to become more and more awake. However, new research shows that it actually takes only 10 minutes for the effect to become apparent. Ana Adan of the University of Barcelona, who led the study, said: "45 minutes is the time when the amount of caffeine entering the bloodstream is at its maximum, but it only takes a few minutes to reach half of that maximum."

The researchers found that men are more awake than women after drinking espresso. They analyzed the situation of 688 college students, including 238 boys and 450 girls. The measurements were taken before and after 10, 20 and 30 minutes of drinking coffee. Considering the differences that may be caused by time, the scientists carried out their studies at noon (11:00 to 1 p.m.) and in the afternoons (04:00 to 06:00). "A lot of studies have shown that caffeine has a stimulating effect, but no one has ever observed its effect in terms of consumer gender," Adan said. Although both men and women wake up after drinking coffee, our research shows that it has a greater impact on men. "

They also found that volunteers became awake after drinking decaffeinated coffee. The researchers pointed out that after decaffeinated coffee was introduced into the study, volunteers' wakefulness also improved, but to a small extent. But in the later testing, there is no significant improvement. "We can't say it's a placebo, and decaffeinated coffee obviously has an effect on people," Adan said. "

Research shows that decaffeinated coffee has a slight effect on both men and women, and women are more affected than men. Previous studies have not shown that decaffeinated coffee also makes people more awake. "if you can't drink standard coffee, decaffeinated coffee may take its place, because it can also wake you up," Adan said. Of course, we have to conduct further research. "

Scientists say the effects of caffeine can last for two or three hours. However, some researchers have pointed out that depending on an individual's unique sensitivity and metabolic rate, it can last as long as four or five hours.
