Slow your breathing
Take a sip of cold water
Look up slightly and blink slowly
Relax your jaw and shoulders
Press your tongue to the roof of your mouth
Pinch the bridge of your nose gently
Focus on a neutral object
Count backward from 100
Hold something cold
Step away from the situation if possible
Breathe out longer than you breathe in
Swallow repeatedly
Keep your face still
Think about a simple task
Wash your face with cool water
Sit down and ground yourself
Tighten and release your hands
Avoid rubbing your eyes
Speak slowly and quietly
Leave the room if you need to
