Here is something very important for your lives.
The right side represents the sun, left side represents the moon.
In about 5 minutes, your headache will be gone. If you feel tired, just reverse, close your left nose and breathe through your right nose.
Do you notice the moment we wake up, which side breathes faster? Left or right? If left is faster, you will feel tired.
There was this period when I suffered headache literally every night, and unable to study. I took painkillers, did not work.
I decided to try out the breathing therapy here: closed my right nose and breathed through my left nose.
