4-7-8 Breathing
Nervous system regulation through breathing
Inhale for 4 seconds, hold for 7, exhale for 8. A powerful technique to calm acute anxiety and facilitate sleep. Practice with our visual pacer and guided audio.

What is 4-7-8 Breathing?
4-7-8 breathing is a nervous system regulation technique popularized by Dr. Andrew Weil, based on the yogic pranayama tradition. It consists of inhaling for 4 seconds, holding for 7 seconds, and exhaling slowly for 8 seconds.
This pattern activates the parasympathetic nervous system (the "rest and digest" response), slowing heart rate and reducing cortisol levels. The prolonged exhalation is key: being longer than the inhalation, it signals the brain that it's safe to relax.
It's one of the most widely used breathing techniques as a complement to EMDR therapy due to its rapid effectiveness and ease of use without supervision.
Caution: If you have a respiratory condition (asthma, COPD), panic disorder, or a cardiovascular condition, consult your doctor before practicing prolonged breath holds. If at any point you feel dizzy, short of breath, or distressed, stop the exercise and return to normal breathing. This technique should feel relaxing, never overwhelming.
How to practice
Preparation
- Sit comfortably with a straight back. Place the tip of your tongue behind your upper front teeth, where the palate begins.
- Exhale completely through your mouth, making a soft "whoosh" sound.
The 4-7-8 cycle
- Inhale through your nose, silently, counting to 4.
- Hold your breath, counting to 7. Don't force it; if 7 is too long, start with 3-5-6 and gradually increase.
- Exhale through your mouth, making the "whoosh" sound, counting to 8.
- This is one cycle. Repeat for 4 cycles to start. With practice, you can work up to 8 cycles.
When finished
- Breathe normally and notice how you feel. The difference is usually noticeable from the first try.
When to use it
4-7-8 breathing is particularly effective in these situations:
- To fall asleep. Dr. Weil describes it as a "natural tranquilizer" for its calming effect on the nervous system — and clinical studies support this: participants report improved sleep quality after regular practice. Practice 4 cycles in bed before sleeping.
- During acute anxiety, when you feel your heart racing or breathing becoming shallow. The 4 cycles take less than 2 minutes.
- Before an EMDR session, to arrive at the office (or video call) in a more regulated state. Combine it with Safe Place to enhance the effect.
- After an argument or conflict, when you need to lower emotional activation before responding.
- As a daily routine, twice a day (morning and night), to improve your overall regulation capacity over time. You can also alternate it with the Butterfly Hug to vary your practice.
