## Summary

Wrist trackers on nearly 94,000 UK adults showed that how you spread movement across the day matters, not just how much you do. Once total activity time was accounted for, more time in short bursts under five minutes was linked to lower death risk, while more time in long blocks of ten minutes or more was linked to higher risk. But constantly flipping between active and sedentary also looked worse. The best profile was plenty of total movement, few abrupt stops, and a moderate share of longer bouts.

## Practical Takeaway

This study suggests breaking movement into frequent short bursts throughout the day may be worthwhile.
