However, it's just the opposite. The No. #1 sign that yoga is really helping a yogi/yogini is reflected in a yawn. That's because a yawn is the sign that the person is relaxing, releasing and resetting. If you have a cat or a dog, you may have noticed that they yawn when they are very, very relaxed. The same is true for humans.
Yawning also results in the body breathing more deeply, more slowly and exhaling more fully. This counteracts the fast shallow breathing experienced as a symptom of stress and anxiety. Furthermore, a yawn stretches the face, neck and even shoulder muscles creating the opposite effect of short, tense muscles.
