What time before sleep I can drink coffee

To optimize sleep quality, it's crucial to manage your caffeine intake properly. Here's what the experts recommend:

1. Caffeine Delay: It's best to avoid caffeine 8 to 12 hours before bedtime. For example, if you aim to sleep at 10 PM, try not to consume caffeine after 10 AM to noon 1.

2. Sensitivity Matters: Individual responses to caffeine vary:

   • If you're highly sensitive, aim for at least 12 to 14 hours prior to sleep without caffeine.
   • If you're less sensitive, you might manage fine with a cut-off around 8 hours before bedtime 2.

3. Caffeine's Half-Life: Caffeine has a half-life of 5 to 6 hours, meaning that after this time, about half of the caffeine remains in your system. This lingering caffeine can disrupt your slow-wave and REM sleep, impacting the overall quality of your rest 3 4.
