Sit or lay down and just notice everything your body is feeling. I like to start with my toes and work my way up to my forehead while I'm just staring off. Reminding myself where I am in the world.
Go on walk
I know you probably hear it a lot.. but going on a walk really can make a fascinating difference.
Listen to music
A lot of variety available to you here. Could benefit from calming music or raging music. You do you ;)
