"We breathe primarily through one nostril for 90 minutes to two hours then shift to the other," Kristin McGee told Leah Wyar in Self magazine (Feb. 2008). "Breathing through the right side makes us alert, while the left side relaxes us."
To calm down: Use right thumb to close right nostril. Inhale through left side slowly for one full breath (four seconds). Pause one second, pressing left nostril with ring finger. Lift thumb and exhale slowly out of right nostril. Repeat eight times.
To perk up: Use right ring finger to close left nostril, inhale through right side slowly for one full breath (four seconds). Pause one second, pressing right nostril with thumb.Then lift ring finger and exhale slowly out of left nostril. Repeat eight times.
Start a new state of mind with just a few whiffs! ;)
