5 Mins Breathing away Headaches

I received an email the other day, forwarded from a friend which says 5 mins to breathe away your headaches.
I've tried meditation to send the qi way up to the head to free up blocked channels, but that usually takes easily 30 minutes a session to feel any effect at all. And soon it comes back.

This one was worth trying, I thought.
For Headache:
Close the right nostril, and breathe through the left nostril.
Right nostril represents the Sun ( for energy ) and left nostril represents
the Moon ( for cooling ).

I had the opportunity to put this to test, and true enough, it could provide relief.

Separately, if one feels tired, one can try breathing through the right nostril to energize one's body.

Happy Breathing.
