Cyclic sighing

Repeat the same pattern: a slow inhale, a second shorter inhale to fill, and a slow full exhale. Nose in, mouth out, unless you choose nose only.

The published pattern is a slow inhale, a second shorter inhale to fill, and a slow full exhale, nose then mouth, for about 5 minutes in the cyclic practice. These second counts were not published.

The seconds are a product default.

• The same report asks each person to keep repeating that sigh for five minutes, and it treats the shorter second breath in as the ordinary form of the pattern. Balban et al., Cell Reports Medicine, 2023

Skip this

• Skip this if a controlled breath feels strained.

Stop if

• Stop if you feel dizzy, lightheaded, tingling in the lips or fingers, chest pain, heart pounding or irregular beats, visual change, nausea, headache, or panic that is rising rather than settling. Sit or lie down. Breathe quietly, without controlling the breath, until it passes.
• If chest pain, fainting, or trouble breathing does not settle, seek urgent care.
