London, June 04: The belief that a cup of coffee stimulates the brain and makes drinkers feel more awake is a myth as scientists have found that the so-called “caffeine high” is just a reaction to the body craving the drug.
A study of 379 people showed regular coffee drinkers needed a hit of caffeine to gain the same level of alertness as non-coffee drinkers, The Telegraph reported.
