Is drinking coffee refreshing equivalent to taking too much medicine? Coffee is healthy

Recently, some experts have said that drinking coffee is tantamount to taking too much medicine, which undoubtedly makes it difficult for coffee lovers. Many people drink coffee is to help refresh, concentrate can better work and study. A new study shows that these drinks are not as powerful as sobering. In fact, it only relies on caffeine to relieve "caffeine withdrawal" symptoms such as fatigue, burnout and headaches, and experts say drinking coffee and tea all the time is actually a sign of drug dependence.

"people who regularly consume caffeine will eventually become dependent on it, and if you keep them away from caffeine, their performance will be lower than normal." "without the help of this drug, their behavior cannot be sustained," said PeterRogers, a professor of biological psychology at the University of Bristow in the UK and a top caffeine expert. If this is your first cup of tea or coffee of the day, it does bring you back to normal, but if you have more, you won't get more excitement. "

Drinking coffee to refresh is equivalent to taking too much medicine.

Professor Rogers has been studying coffee and its effects for more than 20 years, and he and the rest of the research team have given up caffeine. "overall, caffeine is not particularly helpful. It triggers caffeine withdrawal and increases blood pressure, which is not a good thing. I sometimes feel that the biggest effect of my research is in my unit. Four or five of my colleagues have given up caffeine and we all drink decaf. "

Relying on coffee is counterproductive but has no brain-awakening effect.

The idea that caffeine does not make the brain active may sound absurd, but this is the result of Professor Rogers' research. In one of the key studies, about 300 volunteers were divided into two groups, those with moderate to high caffeine intake and those with low caffeine intake, who were assigned not to drink coffee for 16 hours and then randomly divided into two groups to receive a placebo or coffee. The results were very interesting, although people who often had coffee improved their spirits after drinking coffee, but their alertness was the same as that of the other group who received a placebo. This means that drinking coffee does not make people more awake than not drinking coffee. The study has been published in the Journal of Neuropsychopharmacology (journalNeuropsychopharmacology).
