Q: Is Yawning A Source Of Hyperventilation?
Sasha‘s Answer: Contrary to a common assumption, Dr. Buteyko considered yawning being an exception from a harmful effect of mouth breathing and hyperventilation. Yawning helps to normalize gas exchange and often follows relaxation. Many people who start practicing Buteyko Breathing Normalization, experience intense yawning, which is considered to be a sign that the method is applied effectively. To control this reaction is a mistake. The advice to yawn with your mouth closed contradicts Dr. Buteyko’s work.
