Napping Done Right
Matthew Walker's honest take on naps: a real performance tool for some people, a sleep-wrecker for others. The trick is knowing which one you are, and how to nap if you do.
Walker's view on napping is nuanced, not a blanket yes or no. The afternoon dip in alertness is natural, and a short early nap can suit people who sleep well at night. But for anyone with insomnia or trouble falling asleep, napping can quietly sabotage the night. This protocol sorts that out.
Why it works▼
Work out if naps help or hurt you
If you have insomnia or trouble falling/staying asleep, naps reduce your night-time sleep pressure and make things worse. If you sleep well, a short nap can genuinely restore alertness.
Keep it short
A short nap refreshes you without dropping you into deep sleep and the grogginess (sleep inertia) that follows a long one.
Keep it early
A late nap is like snacking before dinner: it kills your appetite for sleep at bedtime. Riding the early-afternoon dip is the sweet spot.
After a bad night, do nothing
Walker's counterintuitive advice: resist compensating. Overcorrecting after one rough night usually just disrupts the next one too.
Make a quick dark, quiet nap easy
Blocking light and noise lets a 20-minute nap actually land, especially in a bright office or daytime room.
Can't nap? Use NSDR instead
If you can't or shouldn't nap, NSDR gives some of the restoration without reducing your night-time sleep drive.
