A cup of strong coffee has a greater effect, when a man drinks it than a woman drinks it – informs the letter “Progress in Neuro-Psychopharmacology & Biological Psychiatry”. During the research conducted on 668 healthy volunteers by scientists from the University of Barcelona, containing 100 milligrams of caffeine, a cup of espresso gave men energy after 10 minutes. Women reacted less well. The maximum level of caffeine in the blood is reached after approx 45 minutes. According to specialists, this effect may be partly psychological – coffee with almost no caffeine (5 milligrams in a cup) it also had a stimulating effect – for decaffeinated coffee it was stronger for women.
