A well-timed cup can make your day easier
For the biggest mental boost, wait until after 9am to have your first cup of coffee of the day. Research from the University of Sheffield found this is when your morning cortisol levels drop, making the caffeine more effective.
A mid-afternoon coffee break with colleagues allowed workers to return to their desks more focused and relaxed, in a study conducted at Linköping University in Sweden, by giving them a short but sociable time out to talk.

A cup of coffee drunk immediately before a quick 15-minute nap helped subjects feel more alert and energised than those who either only slept or drank coffee, according to research from Loughborough University.
After reviewing more than 1,000 human and animal studies the World Health Organisation last year removed coffee from the list of possible carcinogens, and added that it can actually reduce the risk of getting liver cancer.
