4-7-8 Breathing
A calming breath, inhale for 4, hold for 7, exhale for 8, often used to ease anxiety and wind down for sleep.
About this tool
The 4-7-8 technique, popularized by Dr. Andrew Weil, is a paced breathing exercise: you breathe in quietly through the nose for a count of 4, hold the breath for 7, and exhale slowly through the mouth for 8. The defining feature is the long exhale, twice the length of the inhale, which strongly engages the body's relaxation response.
A longer out-breath is one of the most reliable ways to slow the heart and calm the nervous system. By holding for 7 and stretching the exhale to 8, this pattern deliberately lengthens that calming part of the cycle, which is why many people find it useful for falling asleep, easing anxiety, or settling racing thoughts.
Begin with no more than four full cycles in a sitting, and keep the breathing gentle rather than forced. The counts matter less than the ratio: as long as the exhale is clearly longer than the inhale, you are getting the benefit. As it becomes familiar you can do it more often.
If you feel dizzy or short of breath, stop, breathe normally, and try again later with shorter, gentler counts. It is meant to feel soothing, never strained.
