Box breathing: the 4-4-4-4 technique, explained

Box breathing, also called square breathing or 4-4-4-4 breathing, has four equal steps: breathe in for 4, hold for 4, breathe out for 4, hold for 4. Picture tracing the four sides of a square. It is often taught to people who need to stay calm under pressure, such as athletes and first responders, because it is easy to remember and you can do it anywhere.

  2. Breathe out gently to empty your lungs.
  3. Breathe in through your nose for a count of 4.
  4. Hold for 4.
  5. Breathe out through your mouth for 4.
  6. Hold with empty lungs for 4.
  7. Repeat for 2 to 5 minutes.

Tips for beginners

When it helps most

Box breathing is a good reset: before an exam, a meeting or a hard conversation, when you notice your breathing has become fast and shallow, or when your thoughts keep looping at night. Its steady, even rhythm gives your mind something simple to follow.

Box breathing or 4-7-8?

Both slow your breathing down. 4-7-8 has a long breath out and is popular at bedtime. Box breathing is even and alert, which suits the daytime. If holding your breath doesn't feel good, try a rhythm without holds, such as in for 4 and out for 6.
