Sleep Science 101
Understanding the mechanics of sleep is the first step to mastering it. Our guides break down complex topics into actionable advice.

Waking up at the wrong moment can leave you groggy, even if you've slept for 8 hours. These guides help you navigate those cycles.

Quick Sleep Tips
Small changes that yield big results.
- The 10-3-2-1 Rule: No caffeine 10 hours before bed, no food 3 hours before, no work 2 hours before, and no screens 1 hour before.
- Napping: Keep naps to 20 minutes (power nap) or 90 minutes (full cycle). Anything in between risks sleep inertia.
- Consistency is King: Your circadian rhythm thrives on regularity. Try to keep your wake-up time within a 30-minute window, even on weekends.
