Welcome All,
The Yawn and Deep Breath (YDB) seems to be a new issue and nothing to worry, simple exercises makes it recover better. This is exactly i experienced a week before.
All techniques like Meditation, Buteyko method and Pranayama are very good to bring YDB to zero. AS per my personal experience medication does not solve the cause at all. Get guidance with Wikipedia for best understanding of these methods.
Steam inhaler (Vicks Vapourup) also exercises the breathe in/out process, so it could be practiced for a good relief.
I signify Yawn and Deep Breath (YDB) is a cause of mental stress or depression or anxiety. Actually this issue relies on two things i.e. 'think and feel between mind and heart', which must be well synchronized. i.e.
1. One should not think much of a pain that is less happening and troublesome, forget and forgive easily.
2. Should deliver a normal breathe in/breathe out at regular intervals of time, a normal process which we may forget because of pressure.
3. This simple say could help "take inputs to your mind and body the amount it can digest and omit the rest".
4. Forget difficulties and unfortunate happenings. Even forget YDB and continue your work, it works better.
5. While at stress relax for some time, i.e. stop and continue the work again.
6. Try to engage yourself in enjoyable work for the entire day, when awake. Hope sleep
does not disturb you.
7. Laugh wholly, that makes you less tiresome and more healthy!.
8. Spend more time in the garden and in sea-shore daily, for fresh air to replenish.
9. Drink warm water in all season that soothes the internal system.
10. Take a short walk, jog, simple physical game that results with sweat helps better.
Get relieved completely soooon!!!!.
Life is short, Enjoy with hale.
