The Physiological Sigh: A Quick Way to Release Tension

A deep sigh is one of the body's natural ways to reset. You can also do it on purpose. Here is how.

We all sigh many times a day, often without noticing. Sighing is a natural reflex that helps re-open tiny air sacs in the lungs. It also often comes when we feel relief.

The "double inhale" sigh

A version made popular by researchers at Stanford is sometimes called the "physiological sigh":

1. Breathe in through your nose. 2. At the top, take a second, small sip of air through the nose. 3. Breathe out slowly and fully through your mouth.

Repeat two or three times.

What research suggests

In a small 2023 study from Stanford, people who practiced five minutes a day of breathing with long, slow exhales, including this cyclic sighing, reported better mood and less anxiety over a month compared with a mindfulness meditation group. It was a small study, and more research is needed, but the practice is simple and gentle.

When to use it

  • When you notice tension in your chest or shoulders.
  • After reading a stressful message.
  • In the car before going into a busy place.
  • As a short reset in the middle of the day.

Keep it soft

Don't force big, dramatic breaths. A gentle sigh is enough. If you feel light-headed, return to normal breathing.
