The Science (Stanford Study)

A 2023 Stanford study found that just 5 minutes of cyclic sighing daily was more effective at reducing stress than mindfulness meditation.

How it works:

  • The double inhale maximally inflates the lungs' air sacs (alveoli)
  • This reinflates collapsed alveoli, improving oxygen-CO2 exchange
  • The extended exhale activates the parasympathetic nervous system
  • This combination rapidly shifts the body from stress to calm
