Divide work into 90 minute bouts to optimize your focus

Explanation: Ultradian rhythms are cycles that we go through from the time that we are born until the time we die, even during sleep. Every 90 minutes, we switch between focused and calm states of mind. This happens because of rising and lowering levels of cortisol (glucocorticoid).

How to make this easier

• Notice the time when you feel most alert in the morning. It's your natural rhythm

• Set a 90-minute timer or stopwatch

• Allow yourself a 10-15 minute focus warmup

• Eliminate distractions by removing your phone or turning off wifi
