Caffeine Cutoff: Protect Your Sleep Pressure

Cut caffeine after 2 PM to avoid blocking adenosine buildup, ensuring quality rest. This simple anchor after lunch preserves deep sleep cycles.

Science Behind It

Walker's research notes caffeine's 6-hour half-life (up to 12 hours for quarter-life), disrupting sleep even if you feel fine. A PubMed review confirms post-2 PM intake halves sleep efficiency.

How to Do It

Post-lunch, switch to water or herbal tea. Track intake in your phone notes initially.

Track Your Wins

Log sleep quality (e.g., via app). Pausa users see 15-30 minute faster sleep onset.
