Frequently asked questions

Why 90 minutes for deep work?

Research on ultradian rhythms shows the brain naturally cycles through 90-minute periods of high-frequency activity followed by 20-minute rest periods. Working with this rhythm maximises focus and prevents burnout.

What counts as deep work?

Deep work is professional activity performed in a state of distraction-free concentration — writing, coding, design, analysis, or any task that pushes your cognitive capabilities. Email, Slack, and meetings are not deep work.
