4-7-8 Breathing
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Lie in bed. Exhale completely through mouth. Inhale through nose for 4 counts. Hold for 7 counts. Exhale through mouth for 8 counts. Repeat 4-8 cycles.
How it works
Activates the parasympathetic nervous system and lowers heart rate. Extending the exhale longer than the inhale signals safety to the nervous system. The same mechanism underlies standard clinical relaxation protocols.
