Start by breathing in for 4 and out for 8. Then try visualising these three objects in front of you. Three different types of breathing using the diaphragm.
1. Visualise a frosted window pane and blow air into the pane so you can see through it
2. Pretend you have a hot bowl of soup and you need to blow on it to cool the soup down
3. Visualise a needle pricking a piece of paper in front of your face. Breathe into the very small hole.
