Choosing a nap length
Many people find 10 to 20 minute naps refreshing without the grogginess that can follow deeper sleep. A 26 minute nap became popular after a NASA study on pilots. Around 90 minutes allows a full sleep cycle. Add a few minutes if you take a while to drift off.
Keep the screen on and the volume up: a sleeping phone or laptop may not play the alarm. For a wake-up at a set clock time, use the online alarm clock. For background sound, the white noise timer.
Frequently asked questions
Will it work if my screen locks or I close the tab?
Only while the page is open. The countdown keeps time from your device clock in a background tab, but phones and laptops can pause or silence web pages when they sleep, lock or close the tab. For anything that really matters, also set your device's own alarm.
