Caffeine has a half-life of about 5–6 hours. That means your 3 p.m. pick-me-up is still in your system at 9 p.m. (and beyond).

🌟 Today’s Sleep Tip: Set a Cutoff Time

Aim to stop caffeine intake at least 8 hours before bed.

  • Bedtime at 10 p.m.? → Last coffee at 2 p.m.

  • Bedtime at 11 p.m.? → Last coffee at 3 p.m.

👉 Sensitive to caffeine? Push that cutoff even earlier.
