4–7–8 BreathingDr. Andrew Weil’s method for calm & sleep support
4-7-8 breathing is a gentle ratio breathing method often used for relaxation, stress reduction, and sleep support. Use the guided trainer below or explore related techniques like box breathing and coherence breathing.
Guided 4–7–8 Breathing
Inhale 4s → Hold 7s → Exhale 8s. Do 3–4 gentle rounds. If you feel light‑headed, shorten the holds or stop.
Step: Inhale (nose)

Background & origins
The 4–7–8 breath is modern, but its roots trace to pranayama—ancient yogic practices that train controlled inhalation, gentle retention, and lengthened exhalation.
- • The method draws from pranayama patterns that coordinate puraka (inhale), kumbhaka (hold), and rechaka (exhale).
- • Dr. Andrew Weil adapted and simplified these traditions into the specific 4–7–8 ratio for accessibility and clinical use.
- • He taught it widely through the University of Arizona Integrative Medicine program, books, and public lectures, helping bring it into mainstream Western stress‑reduction.
In short: breath retention and paced exhalation are ancient concepts; the 4–7–8 format is Dr. Weil’s modern presentation that many find easy to learn and remember.
