The Physiological Sigh: A Breathing Exercise for Stress

Methods and Practices
1 minute

When anxiety arrives suddenly, a full meditation or yoga session may not be practical. The physiological sigh is a short breathing exercise, studied by Stanford researchers, that you can try as a gentle pause.

What is the technique?

A physiological sigh consists of an inhalation through the nose, a second smaller sip of air, and a long exhalation through the mouth. Sighing also occurs naturally, for example around sleep or after crying. The exercise uses this pattern deliberately, with an emphasis on a comfortable, slow exhale.

How to practise

  1. Take a comfortable breath in through your nose.
  2. Before exhaling, add a second small inhalation through your nose.
  3. Breathe out slowly through your mouth, without forcing the air out.

Try one or two rounds, then return to natural breathing. If it feels comfortable, repeat a few times. Do not keep taking large breaths rapidly. Stop if you feel dizzy, breathless or more anxious.

What does the research suggest?

A Stanford study of cyclic sighing examined brief daily breathing practices over a month. The findings suggest that an exhalation-focused routine may improve mood and reduce resting breathing rate. They do not establish that a few sighs will stop a panic attack or treat an anxiety disorder.

When might you try it?

  • When you notice everyday anxiety rising.
  • Before an important conversation or public speaking.
  • During a break after physical or emotional effort.
  • As a short pause during the working day.

The physiological sigh can be a simple way to bring attention to your breathing. Keep it gentle and judge it by your own comfort. Persistent anxiety or recurrent panic deserves professional support, and breathing exercises can be used alongside appropriate care.
