There are lots of ways that you can relax. Try some of these and see how they make you feel:

Calm breathing
If you make your breathing slower, deeper, and more steady then your body will relax:
Breathe in slowly through your nose
Pause for a moment
Then breathe out slowly through your mouth

Relaxing your muscles
You can relax by letting the tension out of your muscles. A great way to do this is to tense and then relax all of the muscles in your body. Sit in a chair or lie on the floor and then:
Clench your fists … then release
Tighten the muscles in your arms … then relax
Push your shoulders back and up … then release
Tighten the muscles in your tummy … then relax
Tense the muscles in your legs … then release
Curl up your toes and clench your feet … then release
Scrunch up the muscles in your face … then relax

Use the power of your imagination
Imagine doing something or being somewhere that makes you happy. Close your eyes, take a deep breath, then imagine finding yourself in a place or doing something that makes you really happy. Picture all of the details – the sights, sounds, smells and tastes. Notice all of the sensations. Notice how your body feels when you are in this place.
