Your morning cup of joe not only helps you power through the early hours, but research shows its effects can last until bedtime. 99% of caffeine is absorbed within 45 minutes, but the half-life can range from 1.5 to 9.5 hours. So when should you stop drinking coffee? Leading sleep specialist Dr. Michael Breus warns against consuming coffee past noon for optimal sleep. He explains how caffeine can impact sleep and offers tips for better shut-eye.
Caffeine and sleep are connected, but not in a positive way. Caffeine blocks the sleep-regulating neurotransmitter adenosine, disrupting your sleep-wake cycles. To reduce caffeine’s long-term effects, Dr. Breus advises cutting off coffee consumption well before bedtime, preferably by noon or 2 p.m. since the half-life of caffeine can be up to 8 hours.
Establishing a caffeine cutoff time, being mindful of caffeine intake, delaying coffee consumption in the morning, and avoiding sugary coffee add-ons can all promote better sleep. Consistency in bedtime routines and minimizing tossing and turning are also essential for quality shut-eye. Following these habits can help you achieve restful sleep and improve overall well-being.
