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. But there’s no standard recommendation about what time you should stop drinking coffee for better sleep. Some research suggests that you should stop around 6 hours before bedtime. But the ideal gap between your last cup and getting in bed may be bigger or smaller, depending on your body and individual needs.The fix is simple – wait 90 minutes upon waking for your first sip of coffee! The end result: more energy throughout the day, less mid-day drowsiness, and better sleep at night.
