Under half an hour is the sweet spot — on purpose
A nap of 10 to 25 minutes keeps you in the lightest stages of sleep, and that is exactly what makes it work. You get the drowsiness knocked off and some genuine alertness back, but you wake from light sleep, so there is no long groggy tail — you can be useful again within a couple of minutes of the alarm.
Two things protect the sweet spot. First, set the alarm before you lie down, not "in a minute" — the entire benefit depends on actually stopping at the time you picked. Second, remember the timer starts when you fall asleep, not when you close your eyes; if you usually take ten minutes to drop off, a 20-minute alarm buys you a 10-minute nap, which is still a real nap.
If you drink coffee, the classic trick is to drink it right before this nap. Caffeine takes roughly 20 minutes to land, so it kicks in as the alarm rings — the nap and the coffee wake you up together instead of fighting each other.
Waking up from it
Whatever the length, the last step is the same: the alarm has to end with you upright. A browser alarm's Stop button is one click away, and one click is well within reach of a brain that is still mostly asleep — which is fine for a desk nap and risky for anything you genuinely must wake up from.
If the stakes are real — a shift, a flight, an exam — put the alarm on your iPhone across the room instead. WakeUpBroo has no snooze and no dismiss button; it stops only when you type a rotating code from wakeupbroo.com/code on the screen you left over here. The walk is what actually ends the sleep.

FAQ
Frequently asked questions
Is 10 minutes enough for a nap?
Yes — 10 minutes keeps you in light sleep, which is what makes short naps refreshing. You wake without much grogginess and the benefit shows up within a couple of minutes.
Will this 10 minutes alarm work if I close the tab?
No. A browser alarm only runs while the page is open, so leave the tab open, keep the computer awake, and check the volume with the test button before you rely on it.
Does the timer start from when I press start or when I fall asleep?
From when you press start. If you usually take ten minutes to fall asleep, you'll sleep about ten minutes less than the alarm length — worth remembering for short naps, where those minutes are most of the nap.
What if I sleep through the alarm?
A browser alarm stops with one click, which a half-asleep brain manages easily. If you regularly sleep through naps or alarms, use one that can't be dismissed from where you're lying — WakeUpBroo for iPhone has no snooze and no dismiss button, and stops only when you type a rotating code from wakeupbroo.com/code on another device.
