A cup of intoxicatingly fragrant coffee is the first thought in the morning for most people. But contrary to the belief that we cannot start the day without a dose of caffeine, we actually can, because the effects that you attribute to coffee are created by the body itself. Behind it all is the daily or circadian biological rhythm, our internal biological clock, which, among other things, takes care of the production of cortisol, the stress hormone that prepares the body for action and is directly related to stress and alertness. But you thought it was coffee and that you knew how to drink it. You have lived in error.
