Whistle release
In this exercise, I slowly force air through a small opening formed with my lips, producing a whistling sound. The exercise slows my breathing and audibly expels the negative.
Usually, people whistle when they are happy, but the sound I generate is low-pitched and not so cheerful. It’s more like the sound of a windstorm.
I generate a whistling sound only on the exhale. There is also the option of ‘back whistling,’ but I avoid it because it requires mouth inhaling.
The breath-hold allows indication. If I exhale slowly enough, post the breath-hold I reach ‘air hunger start’ more rapidly.
