The science

Slow, paced breathing increases heart-rate variability and engages the parasympathetic nervous system. Patterns like box breathing and 4-7-8 are widely used for stress reduction and focus.

Frequently asked questions

What is box breathing?

Box breathing is a four-part pattern — inhale, hold, exhale, hold — each for an equal count (commonly four seconds). It is used by athletes and the military to stay calm under pressure.

What is the 4-7-8 technique?

You inhale for 4 seconds, hold for 7, and exhale for 8. The long exhale strongly engages the relaxation response, making it popular for winding down.
