They are actually different: the right represents the sun, the moon left.
During a headache try closing the right nostril and left to respirar.dentro uses about five minutes, the headache should disappear.
If you feel tired, to, do the opposite: close the left nostril and breathe through your right. In a moment your mind will be relieved.
The right side belongs to the "heat" (The Sun), so it heats up quickly, the left is the "cold" (The Moon.) Most women breathe with the left side of the nose, then cooled quickly. Most people breathe through the right nostril and that influences them.
Pay attention at the time to wake up, which side breathes better, the right or the left?. If the left you will feel tired. Then close the left nostril and use your right to breath, is relieved rápidamente.Esto can and should be taught to children, but is most effective when practiced by adults.
My friend used to have severe headaches and always went to the doctor. Time was suffering headaches literally every night, feeling unable to study. He took painkillers, but did not work. One day he decided to try this therapy breathing, he covered the right side of the nose and breathing through the left. In less than a week the headache disappeared. He continued the exercise for one month.
