How to calm down when stressed
Take a short break.
Just the act of separating yourself from your stressor for a few moments can calm you down. You can use this time to think about the situation, why it is stressing you, and how you can resolve the problem.
Whether it's a bathroom break during a meeting, a brief walk, or just turning away from the pile of papers on your desk for a minute or two, try to take a short break from work. Taking a time out can help increase energy and creativity.
