Focus rhythm guide

Use the clock to support attention, not police it.

Short cycles can lower the barrier to starting, while longer cycles may suit complex work that needs time to become immersive.

Match the rhythm to task friction

Try 25/5 for avoidance or unfamiliar work, 50/10 for steady study, and 90/20 for deep work that benefits from fewer transitions. Adjust from observed energy.

Treat the break as part of the system

A good break changes posture, vision, or environment without opening a new attention loop. Protecting distracting apps during short breaks can make returning easier.

Is 25 minutes always the best focus duration?

No. It is a useful starting point, not a rule. The best rhythm is one you can begin, complete, and repeat for the kind of work you are doing.
