What twenty minutes are good for
Deep work blocks
Twenty minutes of undistracted work is a realistic unit for writing, coding, or studying before you check anything.
20-20-20 eye rule
Every 20 minutes, look at something 20 feet away for 20 seconds. Keep this timer running while you work at a screen.
Naps and rest
Twenty minutes is the upper end of a refreshing nap. Set it and lie down without checking the clock.
Baking and roasting
Muffins, cookies on a second tray, and many vegetables finish around twenty minutes.
Tips
- Press R when the alarm rings to start the next 20-minute screen block.
- Use the custom timer if you want 20 minutes plus a 20-second eye break built in.
Questions
What is the 20-20-20 rule?
A guideline for reducing digital eye strain: every 20 minutes, look at something about 20 feet (6 metres) away for at least 20 seconds.
Is twenty minutes too long for a nap?
It is at the top of the recommended range. Go beyond about 30 minutes and you risk waking from deep sleep feeling worse.
