Rather that having coffee first thing in the morning, what about waiting an hour or two? Some people say that this gives a "more natural" waking-up process and avoids an afternoon slump. This claim is wrong. Proponents of this myth claim that caffeine interferes with the rise of the hormone cortisol that occurs naturally in the first hours after waking. But it has been shown that this effect is absent or minimal in most people, particularly those who are regular coffee drinkers. This schedule may work for some folks, but as a general rule for everyone the idea of delaying that first coffee is not supported by any evidence.
