What is the 2 hour coffee rule?
Quick answer: the 2 hour coffee rule suggests waiting at least two hours after waking up before drinking your first cup of coffee. This guideline aligns with the body’s cortisol levels, aiming to optimize both the effects of caffeine and the body’s natural wakefulness cycle. Take a week off from coffee (caffeine) and the boost you feel when you start drinking coffee again increases; the international archives study found that changes in adenosine receptor levels typically reverse after a 7-day caffeine break. Fortunately, you don’t have to go coffee cold turkey.To avoid that afternoon crash, Huberman suggests waiting 90 to 120 minutes after waking before reaching for your favorite brew. Theoretically, doing so allows adenosine levels to rise slightly, ultimately making caffeine more effective at blocking those receptors and keeping us alert.

Coffee drinkers may be paying for stimulation, but what they are really seeking is relaxation. This is the essential paradox that makes up the atmosphere of the cafe.
