Dark, Quiet, Cool

Insight

Three levers decide most of sleep quality before you ever close your eyes: darkness, quiet and temperature. They are also the three most ignored — because they're someone else's problem tomorrow morning.

Why it works

The sleeping brain keeps processing the environment. Light delays the deeper stages, noise fragments them, and a warm room prevents the core temperature drop that sleep onset depends on.

Practical takeaway

Audit your bedroom tonight against the three levers. Improve one — blackout, earplugs, a cooler setting or thinner bedding — and give it a week.

Good question to ask someone

What is your bedroom telling your body about sleep?
