Why set an alarm for 15:00?
Lunchtime and naps dominate this window. Setting an alarm at 15:00 is typical for not oversleeping a power nap: 20 minutes is the ideal length according to NASA research to recover alertness without entering deep sleep. More than 30 minutes and you wake up worse.
Frequently asked questions
Will the alarm ring if the tab is in the background?
Yes, the alarm rings even if the tab is in the background or minimized, as long as the browser stays open. The internal tick uses absolute timestamps rather than counters, so it survives background tab throttling.
How long should a nap last?
Between 10 and 20 minutes is ideal to recover alertness without entering deep sleep. NASA recommends exactly 20 minutes. If you sleep more than 30 minutes, you wake up with sleep inertia and feel worse for a while.
What is a coffee nap?
You drink a coffee, set an alarm for 20 minutes, and nap. When the alarm rings, the caffeine is starting to take effect. It is the perfect combination: light sleep clears adenosine and caffeine blocks the remaining receptors.
