I breathe through both of my nostrils at the same time...I dont know about you...maybe your nose is stuffed??

Because the brain cycles between hemispheres every 90 minutes or so, one becoming dominant over the other, when you breathe through your right nostril the left side of the brain is active and vice versa, it is believed that if you block one nostril you can engage the other hemisphere, logical hemisphere = right nostril (left hemisphere active), and creative hemisphere = left nostril (right hemisphere active). Research has found there really is such a thing as the nasal cycle (two to eight hours long) and that there is a connection between the predominant nostril and the opposite brain hemisphere. A 1988 study found that right nostril breathing significantly increases blood glucose levels while left nostril breathing lowers it. Interestingly, yogis believe that diabetes is caused by a nasal cycle abnormality of predominantly breathing through the right nostril for many years. A 1993 study found that forced right nostril breathing (four times a day for one month) significantly increased oxygen consumption compared to breathing through the left nostril. A 1994 study published in the International Journal of Psychophysiology found that alternate nostril breathing appears to have a balancing effect on the functional activity of the left and right hemisphere of the brain. Your left brain is the logical structured side while your right brain is the creative imaginative side. http://www.abc.net.au/science/k2/moments/s198395.htm http://en.wikipedia.org/wiki/Nasal_cycle

i breathe through both my nostrils all the time. im normal.CUNTO.

The nostrils change cycles about every 2 1/2 hours,with going from left to right then back again.Yogic exercises also used this knowledge.

Until I became congested due to swollen turbinates I breathed through both, whether one more than another who cares because if you can breathe clearly thats all that matters. Now if you are noticeably breathing through one then something is wrong. I'm going to have the turbinate coblation so I can start back breathing clearly through my nostrils and sleep better at night!
