Is Your Afternoon Coffee Stealing Your Deep Sleep?
Video Highlights:
This video reveals how that afternoon latte might be sabotaging your rest. It breaks down the long-lasting effects of caffeine and provides expert advice on the ideal “cutoff time” for your last cup.
[00:03] The 6-Hour Half-Life:
Latest research shows that caffeine has a half-life of 5 to 6 hours. That means the latte you drank at 3:00 PM still has half its caffeine lingering in your system at 11:00 PM.
[00:13] Impact on Sleep Architecture:
Consuming caffeine too late can reduce total sleep time by 45 minutes and cut deep sleep by over 11 minutes. Additionally, it can take nearly 10 minutes longer to fall asleep.
[00:21] Long-term Brain Effects:
Chronic high caffeine intake can shift your entire sleep rhythm, delaying the REM (Rapid Eye Movement) phase. This means your brain doesn’t have enough time to complete essential repairs.
[00:29] The Expert “Cutoff” Rule:
Experts recommend finishing your last cup at least 9 hours before bedtime. If you plan to sleep at 11:00 PM, you should stop caffeine intake by 2:00 PM.
