Espresso Coffee Cup
A new study by a group of researchers from the University of Barcelona, Spain, has found that caffeine has greater effect on men compared to women and those effects starts just 10 minutes after it is drunk. This is for the first time someone has documented the interesting differences in the positive effects that caffeine may have on alertness between men and women.

The researchers have based their findings on an experiment conducted on 668 healthy volunteers (238 male and 450 female), aged around 22. The volunteers were asked to drink either a classic espresso containing 100mg of caffeine or a decaffeinated espresso containing 5mg of caffeine. Then their changes in alertness over time were measured by the researchers.

After analysis of data, the researchers found that both men and women saw an improvement in their activity levels after drinking the classic espresso. They also found that, 45 minutes is the time needed for maximum caffeine concentration to be reached in the blood. But withing a few minutes of drinking coffee, the levels reached half the maximum concentration and the effect was appeared to be greater in the men.

Interestingly, the researchers also found a small subjective improvement in the participants’ state of alertness after drinking the decaffeinated espresso. Previously scientists were not aware about any effect of decaffeinated drinks on alertness.The findings of the study have been published in the latest edition of the 'Progress in Neuro-Psychopharmacology and Biological Psychiatry' journal.
