Pinch your nose and nod your head forwards and backwards quickly whilst holding your breath. Once you feel a strong urge to breathe, sit down with your spine totally straight - you are about to take your first breath.
After you release your nose, you are to resume normal breathing but ensure you keep your mouth closed. Resist the urge to take a huge gasp of air, instead, take a smaller inhale and then relax all of your muscles during exhalation.
When you hold your breath and perform repetitive physical movements, all the cells of your body, including the airways, lungs, and blood, accumulate more carbon dioxide [CO2]. CO2 is a powerful vasodilator of smooth muscle which lines the sinuses, bronchi and bronchioles (air passages). A vasodilator is a substance that causes smooth muscle to relax thus dilating the tubular passages it lines.
Upon the airways dilating there is quick relief from a blocked nose. Additional effects are due to the dilation of arteries and arterioles when arterial CO2 is increased. CO2 induced vasodilation improves blood and oxygen supply to your nose.
