  • I think it's to prevent the nostrils from drying out. One nostril does most of the breathing, while the other one gets a break.

  • You cycle through which nostril is dominant all day long, about every 30-50 minutes. This is to allow each side to return to body heat equilibrium and recover.

    You pass 10-20k liters of generally colder than bodytemperature air through your nose in a day.
