Twenty minutes: work block and eye break

The 20-20-20 rule is a commonly shared tip for people who spend long periods at a screen: every 20 minutes, look at something about 20 feet (roughly 6 metres) away for 20 seconds. Eye care organisations often suggest this kind of habit to ease tired eyes. This timer is set to 20:00, so it can mark each block.

Ways to spend twenty minutes

  • Screen work block: write, code, design or study, then look out of a window when the alarm sounds before restarting.
  • Short nap: a nap of around 20 minutes is often suggested by sleep guides, because it tends to leave people less groggy than a long one. Naps affect people differently, so adjust to what works for you and avoid napping late in the day if it disturbs your night sleep.
  • Home workout: a circuit of bodyweight exercises with short rests. Choose a pace that suits your fitness and speak to a doctor first if you have health concerns.
  • Reading time: a chapter or a long article, with the phone in another room.
  • Cooking prep: chop vegetables, marinate or start a simple dish.
  • Short meeting: twenty minutes with a one line agenda is often enough for a check-in.

Using the timer for a nap

Set the timer before you lie down, turn off notifications, and make sure the volume is up so you hear the alarm. Most people need a few minutes to settle, so some choose to set it for a little longer. Once the alarm sounds, get up slowly and drink some water. If you cannot sleep, resting quietly is still a break.

Using it for eye breaks

Press Restart after each alarm so the next twenty minute block begins immediately. When it sounds, pick a point across the room or outside, rest your eyes there for about twenty seconds, blink a few times and carry on. If the alarm catches you mid-sentence, finish the thought and then take the break.

If you often forget, keep the page in a pinned tab and leave the sound on.

A 20 minute countdown, ready to start

Twenty minutes fits a lot of everyday jobs, from a short nap to a focused study block. This timer opens at 20:00, so just press Start. An alarm sounds when the time is up.

What a 20 minute timer is good for

  • Power nap: about 20 minutes is a common length for a short nap that leaves you refreshed.
  • Screen breaks: a reminder to look away from the screen regularly.
  • Study block: one topic or one past paper section.
  • Cooking: rice, roast vegetables and many curries need around 20 minutes.
  • Exercise: a brisk walk, a cycle or a yoga session.

Tips

  • For a nap, start the timer first and keep the sound on with the volume up.
  • Combine with the 5 minute timer for a break after each block.

Frequently asked questions

Is twenty minutes the right nap length for everyone?
No. Around twenty minutes is a common suggestion, but people respond differently. If you wake up groggy, try a shorter nap, and talk to a doctor if you are very tired all the time.
Do I have to follow the 20-20-20 rule exactly?
No. It is a simple guideline. The idea is to look away from your screen regularly, so a rough version still helps. See an eye doctor if you have ongoing discomfort.
How many seconds is 20 minutes?
1,200 seconds. The display counts down from 20:00.
Can I pause the timer?
Yes. Press Pause, or the Space bar, and Resume to continue.
Will the timer keep running if I switch tabs?
Yes. The timer counts against your device clock, so it stays accurate in a background tab, and the tab title shows the time left. Some phones pause web pages when the screen locks, so keep the screen on for important timings. The timer asks the browser to keep the screen awake while it runs, where supported.
Why did I not hear the alarm?
Check that your device is not muted and the volume is up, and that Play a sound is ticked. Phones in silent mode may block web audio. The alarm beeps for about 15 seconds, and the display flashes as well.
