Sleep Is the Compound Interest of Wellness
Why no habit returns more per unit of effort than protecting your sleep.

The highest-leverage habit
If you could only improve one thing about your health, sleep would be the strongest candidate. It touches cognition, mood, recovery, metabolism, and immune function.
Three low-effort, high-return moves
- Keep a consistent wake time, even on weekends
- Dim light in the last hour before bed
- Keep the bedroom cool, dark, and device-free
The compounding effect
One good night doesn't transform you. But a consistent week, month, and year of protected sleep changes everything — quietly, the way compound interest does.
Sleep is the foundation every other habit stands on.
Protect it, and the rest gets easier.
