Your vagus nerve gets stimulated, creates feelings of rest and digest. (Rest=sleep). You could use your salivary flow as an indicator. If you have plenty of saliva, then the exercise is done properly. There are also some other explanations that your body fights the new breathing patterns. To prevent you from losing harnessed CO2 while you yawn, cover your mouth. And repeat two - three breaths with extended exhales. For example: in for 2 out for 3 and a short pause at the end of the exhale. Repeat. Good luck!
Why does this exercise have me yawning every second breath in? It yhrn forces me to breathe in through my mouth!
Means your super relaxed. Nice.
