Most of the time the switching from side to side is unconscious but if I concentrate, I can cause it to happen consciously. This is really useful when I have a cold and a blocked nostril and I want to get some relief when blowing my nose doesn't help - I just focus on allowing that side of my sinuses to open and after a few minutes it will happen.
