Caffeine Perks Up Men Quicker |
|
December 27, 2008 - A study by the University of Barcelona found that the stimulatory effects of caffeine work much quicker in men than in women. The study which surveyed 688 students with an average age of 22, showed that male subjects showed greater levels of alertness than women - though a study on decaffeinated coffee showed just the opposite. Though the reasons for this are still unclear , what is clear, is that in previous studies, it was believed that caffeine initiated its stimulatory effects between 30-45min. This new study found that effects can be seen in as quickly as 10 minutes.
