While regular, short breaks are important to keep you fresh and focussed, don’t skimp on taking a longer break during the day – typically the lunch hour. A longer break allows you to fully unwind, and to take a 30 minute walk around outside, or a 20-minute nap, and sit down and eat a proper meal away from your desk. These are all essential activities for overall health and wellbeing, which will spill over positively into your work.
