Box breathing — also called square breathing or four-part breath — is a technique used by everyone from Navy SEALs to meditation teachers to restore calm and focus under pressure. Its symmetry is its power.

The pattern is simple: inhale for four counts, hold for four, exhale for four, hold for four. Four equal sides, like the sides of a box. This symmetry signals safety to the nervous system.

Sit upright. Relax your shoulders. Begin by exhaling completely to empty the lungs. Then: inhale slowly through the nose for four counts — one, two, three, four.

Hold the breath at the top for four counts. Keep the body relaxed — this is a gentle hold, not a strain. One, two, three, four.

Exhale slowly through the nose or mouth for four counts. Let the breath leave completely. One, two, three, four.

Hold at the bottom — lungs empty — for four counts. This is often the most challenging part. Stay soft. One, two, three, four.

That is one complete box. Repeat for five to ten minutes. As you become comfortable, you can extend each side to five or six counts. The longer the sides, the deeper the effect.

Box breathing is particularly useful before high-stakes situations — a presentation, a difficult conversation, a moment of overwhelm. It brings you back into your body and into the present moment, where you are always more capable than anxiety suggests.
