Unplug after 90 Minutes

Your brain can only focus for 90 to 120 minutes before it needs a break. 

This is the ultradian rhythm, a cycle that’s present in both our sleeping (the 90-minute cycles during which we progress through the five stages of sleep) and waking lives (as we move from higher to lower alertness).

The 90-minute cycle works well for most of the demanding and creative work, as follows:

• Morning practice is essential.
• Three sessions a day on an average
• Each session is for 90 minutes
• A break is essential between the sessions.

Humans have imagined themselves as machines, doing work linearly, and continuously.

We aren't machines, but organisms that work best cyclically, with intervals and rest periods.
