A well-timed nap improves alertness, memory and mood in just a few minutes. The secret comes down to two things: length and timing.
The right length
10 to 20 minutes is the sweet spot: you get the restorative benefits without drifting into deep sleep. Beyond 30 minutes, you risk sleep inertia, that groggy feeling when you wake up. A 90-minute nap (a full cycle) is another option, but it takes more time.
The right time
The natural alertness dip happens in the early afternoon, between 1 pm and 3 pm. That's the perfect window. Any later, and your nap can eat into your night and create night-time wake-ups.
Key takeaway: 10 to 20 minutes in the early afternoon: the nap that recharges you without knocking you out or stealing your night.
Napping and sleep debt
A nap helps offset a sleep debt occasional, but it's no substitute for good nights of sleep. The KEORA Ring helps you spot when your recovery is low and real rest is needed.
A twenty-minute nap can be worth an hour of coffee. And better.
