According to a study from the Journal of Applied Social Psychology, that cup of coffee you’re drinking in the morning isn’t helping you wake up, it’s actually diminishing your brain power- if you’re a male.
The study examined the effects of coffee when the body is under stress, and found that men’s performance on memory tests was “greatly impaired”, and on average took 20 seconds longer to complete puzzles than those who had consumed decaffeinated coffee. Oddly enough, caffeine had the opposite effect on women, who completed the puzzles 100 seconds faster after consuming caffeine.
The 64 men and women were put in same-sex pairs while completing puzzles, memory challenges, and carrying out negotiations. They were told that afterwards, they would have to give a public presentation about the tasks.
Similarly, a study published in Behavioural Pharmacology a little over a year ago suggested that adolescent boys “may be more susceptible to the reinforcing effects of caffeine,” with females possibly being less sensitive to the effects of caffeine.
