Coffee boost may be in the head

LONDON, Sept. 2 (UPI) -- Some people think drinking coffee boosts their mental performance, reflexes and mood, but that may all be in their head, researchers in Britain say.

Researchers at the University of East London had 88 volunteers ages 18-47, who say they love coffee and drink at least two cups every day, tested for mental performance, reaction times and mood, The Daily Telegraph reports.

Caffeine is a stimulant and combats drowsiness and fatigue.

Those who were told they were given coffee with caffeine -- but in reality drank decaffeinated coffee -- reported noticing a significant improvement in performance and mood and some did better than those who drank coffee with caffeine, the researchers say.

The finding are published in the journal Appetite.
