About the 20 minute timer
Twenty minutes is the length of one 20-20-20 eye-strain cycle (look at something 20 feet away for 20 seconds every 20 minutes) scaled up to a full rest, and a comfortable short meditation length for experienced practitioners.
What you can do in 20 minutes
- A full eye-rest break away from every screen
- A seated meditation long enough to settle the mind
- One batch of oven-baked vegetables or a sheet-pan dinner
- A focused inbox sweep using the two-minute rule
