Noses have a very rich supply of blood which comes through hundreds of tiny blood vessels, venules, arterioles and capillaries.
This is why they bleed so easily and so freely.
Because each one of these vessels is a smooth muscle controlled tube, it stands to reason that if the CO2 level in the blood is too low, then spasm can occur.
The result of spasm is these vessels is a blocked nose.
Most people say that they breathe through their mouth because their nose is blocked.
The reality is exactly the opposite; the nose is blocked because they breathe through their mouth.
The best way to unblock your nose it to increase the amount of CO2 in your blood and also to pass CO2 rich air over the tissues and allow the spasm to relax.
You should feel almost immediate benefits from this.
This will not work as well if you have a viral or bacterial infection, polyps or other physical abnormalities which are responsible for the blockage.
After a gentle exhaled breath, pinch your nose closed with your fingers and make sure that your mouth is closed.
- Nod your head vigorously forward and backward or else walk up and down for around 10-120 steps making sure that both mouth and nose are closed.
- PLEASE NOTE: If you have any neck problems rather do the walking around so that you do not strain your neck.
- When you feel the need to breathe, keep your mouth closed, release your fingers and breathe slowly and gently, in and out through your nose.
- You should feel it start to open almost immediately.
You can do this as many times as you need to unblock your nose.
Remember that the more you breathe through your nose, the more it will stay open. The moment you return to mouth-breathing your nose will block again.
