Physiological Sigh: Two Inhales, One Long Exhale

Do repeated physiological sighs for about 5 minutes: two inhales through the nose to fully inflate the lungs, then a long, complete exhale through the mouth. This is used as a fast real-time reset before or during stressful moments, and as a daily practice for lowering stress and improving mood or sleep by emphasizing the exhale and shifting the nervous system toward calm.

I've talked a lot about physiological sigh. It's called physiological sigh, not just sighing, because it involves this double inhale, long exhale, which is involved in reducing the amount of so-called sympathetic autonomic arousal, again, just alertness.
