Sit down with good posture  

Take a small quiet breath in and out through your nose  

After exhale pinch your nose so no air can come in or out  

Gental nod your head up and down for as long as you can  

When you need to breath in do so through your nose and calm your breathing as fast as you can  

Wait about 30 seconds and start again, repeat this 3 times, your nose should be completely unblocked by the third try  

Repeat this in the morning and evening of each day
