Anxiety Relief - Stand up Straight

When you are anxious muscles tighten, shoulders can lift towards the ears, and you may hold your breath or breathe from the chest. This tells your brain and nervous system that there is a threat. By sitting or standing up straight, will help signal safety to your brain and help slow down breathing.

Give this technique a go: 

Feet Flat on the Floor Plant your feet apart from each other. Have both feet flat on the floor with your weight distributed equally between them.
Stand Tall  Consciously straighten back, from your tailbone up. Lift up your head so your neck is in line with the rest of your spine, rather than dropping forward.
Take a Deep Breath and Broaden the Chest  Breathe in deeply, feeling your lungs expand. Let your shoulders come back and your chest broaden.
