Caffeine affects men more

Ana Adan, author of the study and researcher at UB's Department of Psychiatry and Psychology, said: 'A lot of studies have demonstrated the stimulating effect of caffeine, but there have been no studies. Look at the differences of these impacts by gender '.

Research on caffeine effects is often done with caffeine levels more than normal consumption. According to Ada, this new study lies in 'the perceived difference between men and women, based on the amount of caffeine these people normally use' ( steamed coffee, and caffeine slightly filtered, contains 100mg and 6mg of caffeine).

To determine the effects of caffeine, the scientists conducted research on 668 university students (238 men and 450 women) with an average age of 22. Necessary measures are taken before and after Caffeine consumption (10, 20 and 30 minutes) in the middle of the day (11 am to 1 pm) and in the afternoon (4 pm to 6 pm), to ensure accuracy in case of differences about results due to time of day.

'Although both men and women have an improvement in alertness when using coffee, we observe a greater impact on men.'

When using caffeine-filtered coffee in the study, the authors also found a small improvement in the level of alertness of the participants. Adan commented: 'Although we cannot say it is an alternative, but certainly has the effect of drinking caffeine-filtered coffee (in insufficient amounts to affect people's alertness. use)'.

The results showed a small impact on both women and men when using caffeine-removed coffee. This time the impact on women is clearer. The impact of caffeine-removed coffee has never been studied before.

The authors said: 'If a person cannot drink coffee normally, caffeine-filtered coffee may be a possible solution. It is still necessary to consider whether these impacts are subjective, or they actually have an impact on performance. '

Coffee creates a very fast impact

Caffeine has an almost immediate effect. Previous studies have shown that alertness begins to increase about 30-46 minutes after consumption, new studies show that this effect starts after 10 minutes. According to the researchers '45 minutes is the time needed for the blood caffeine concentration to reach its highest level, but after a few minutes the blood caffeine concentration has reached about half '.

Experts say caffeine's effects persist for 2 to 3 hours, although some authors believe it can last up to 4 or 5 hours depending on the level of metabolism and sensitivity of each fish. multiply and change quite a lot depending on age.
