4-7-8 breathing is a structured breath pattern with unequal phases. It’s perfect for sleep: The long hold and extended exhale work together to activate the parasympathetic nervous system quickly.
I usually do the 4-7-8 method in bed, right before sleep. I find that the hardest part with this breathwork practice is finding the rhythm. The seven second hold before a long exhale can feel awkward at first, but it clicks with practice.
How To
Sit with your back straight, or lie down.
- Tounge placement. Place the tip of your tongue against the ridge behind your upper front teeth and keep it there throughout.
- Empty your lungs. Exhale completely through your mouth with a whoosh sound to empty your lungs.
- Breathe in. Inhale through your nose for 4 counts.
- Retention. Hold your breath for 7 counts.
- Breathe out. Exhale completely through your mouth for 8 counts, making the whoosh sound again.
- Repeat. This marks one cycle, continue for at least four cycles. As the pattern becomes familiar you can work up to eight cycles or as long as you need.
If you want to practice without counting yourself, Ma guides you through each cycle with audio cues and you can set it to automatically switch over to meditation with ambient background music afterwards and gently fall asleep to that stilness.
Safety
Start with four cycles. Do not force the hold if it feels uncomfortable. People with asthma, severe COPD, or high blood pressure should consult a doctor before practicing. If you feel very light-headed, reduce the count and breathe normally until it passes.
What to Expect
The first cycle or two can feel forced. The seven second hold is longer than most people expect, and the eight second exhale requires you to slow down in a way that takes some getting used to. By the third or fourth cycle most people notice their heart rate dropping and their mind quieting. Some feel slightly light-headed at first, but that passes.
What Happens in the Body
When you are stressed, your breathing becomes fast and shallow, lowering CO2 in the blood and signaling danger to the brain. 4-7-8 breathing interrupts that cycle through two mechanisms:
- The seven second breath hold allows CO2 to build slightly, which prepares the blood to release oxygen more efficiently when you exhale.
- The eight second exhale, longer than the inhale, activates the vagus nerve and shifts the nervous system toward parasympathetic dominance.
The ratio of inhale to exhale, roughly 1:2, is what makes this technique particularly effective for calming the body quickly.
Dr. Andrew Weil, who developed the technique, describes it as a natural tranquilizer for the nervous system.
Before Bed
4-7-8 is one of the techniques most commonly recommended for sleep. The combination of breath retention and extended exhale calms the nervous system quickly, making it well suited for use in bed. It works well as a pre-sleep practice.
Where It Comes From
4-7-8 breathing was developed by Dr. Andrew Weil, founder of the Integrative Medicine Center at the University of Arizona, and introduced around 2010. He based it on pranayama, specifically the yogic practice of working with the four phases of the breath cycle: inhalation, retention, exhalation and the pause after exhalation.
What the Research Shows
A 2023 randomized controlled trial on patients after bariatric surgery found that 4-7-8 breathing reduced anxiety significantly more than deep breathing and a control group.
A 2022 PMC study found that the technique improved heart rate variability and blood pressure in healthy young adults.
The research base is smaller than for box breathing or coherent breathing. Most studies are small and focus on specific clinical populations. The physiological mechanism is well understood, but large-scale randomized trials are still limited.
