To unblock your nose, you can try the following exercise:
- Sit down
- Breathe out without any effort (i.e. do not try to empty the lungs)
- Before breathing in again, close your mouth if it is open and pinch your nostrils closed.
- Nod your head 10 - 15 times, or until you want to breathe.
- Keeping your mouth closed, remove your hand from your nose and breathe SOFTLY and SLOWLY through your nose
- Repeat up to 5 times if the nose is very blocked. Be careful that you do not hurt your neck when nodding.
