When you’re on a roll at work – completely focused, tearing through your to-do list – the last thing you want to do is take a break and lose momentum. But research shows that no matter how engaged we are in an activity, our brains inevitably tire, and we become more vulnerable to distractions.

o Sporadic breaks replenish our energy, improve self-control and decision-making, and fuel productivity. We just have to get better about stepping away before we burn out.

o So try blocking out a couple of planned 15-minute intermissions on your calendar, one in the morning, one in the afternoon – and find something active to do with this time.

o Talk a walk, stretch, run an errand, go with a coworker for a snack, etc.

The important thing is to step away from your computer so your focus is relaxed and your mind drifts. Checking Facebook doesn’t count.

Adapted from “Schedule a 15-Minute Break Before You Burn Out” by Ron Friedman.
