The nose has a left and a right side we use both to inhale and exhale.

Actually they are different you would be able to feel the difference. The right side represents the sun, left side represents the moon. During a headache try to close your right nose and use your left nose to breathe.

In about 5 minutes your headache will go.

If you feel tired just reverse close your left nose and breathe through your right nose. After a while you will feel your mind is refreshed.

Right side belongs to ‘hot’ so it gets heated up easily left side belongs to ‘cold’.

Most females breathe with their left noses so they get “cooled off” faster.

Most of the guys breathe with their right noses they get worked up.

Do you notice the moment we wake up which side breathes faster? Left or right? ?
If left is faster you will feel tired.

So close your left nose and use your right nose for breathing you will get refreshed quickly.

This can be taught to kids but it is more effective when practiced by adults.

My friend used to have bad headaches and was always visiting the doctor.

There was this period when he suffered headaches literally every night & unable to study.

He took pain killers but they did not work.

He decided to try out the breathing therapy here: closed his right nose and breathed through his left nose.

In less than a week his headaches were gone! He continued the exercise for one month.

This alternative natural therapy without medication is something that he has experienced.
