How to Do a 5-Minute Breathing Exercise to Reduce Stress

Slow, paced breathing is one of the fastest ways to lower stress without taking medication. Doctors at Mayo Clinic, Harvard Medical School, and the American Lung Association all teach paced breathing as a first-line tool for moments of worry, racing heart, tight chest, and trouble sleeping. The reason it works lies in the body's nervous system. When you slow the breath to about 6 breaths per minute, the heart rate slows, blood pressure drops a few points, and the part of the nervous system that triggers the "fight or flight" response quiets down. The change happens within 90 seconds and reaches its full effect in about 5 minutes.

The most studied pattern is called 4-7-8 breathing, taught by Dr. Andrew Weil at the University of Arizona. You inhale through the nose for 4 seconds, hold the breath for 7 seconds, and exhale through pursed lips for 8 seconds. The long exhale is the key — extending the out-breath longer than the in-breath sends a calming signal through the vagus nerve, which carries the message to slow down to the heart, lungs, and digestive system.

For people with COPD, asthma, or other lung conditions, the 4-7-8 pattern may feel too long. A gentler pattern called Box Breathing — inhale 4, hold 4, exhale 4, hold 4 — works almost as well and is easier on the lungs. Both patterns are safe, free, and require no equipment. They can be done sitting in a chair, lying in bed, walking down a hallway, or waiting in a doctor's office.

The exercise has more uses than stress relief. Many older adults use paced breathing to fall asleep faster, to settle nerves before a medical appointment, to manage hot flashes, to ease mild dizziness, and to slow a racing heart from too much caffeine. Studies in the journal Frontiers in Human Neuroscience show that practicing paced breathing for 5 minutes a day, twice a day, lowers resting blood pressure by 4 to 6 points after 8 weeks.
