Answer:
Take a Deep Breath
Breathing deeply and slowly triggers the body to stop releasing stress hormones and start to relax. Concentrating on your breathing can also help to distract your mind from whatever is bothering you so that you focus only on what is happening at that moment.
Breathe in deeply through your nose – you should breathe all the way into your belly and not just your chest. Hold for a moment and breathe out slowly through your mouth. Take a few minutes just to breathe and you should find yourself feeling calmer quickly.
