Shrink Definition
Box breathing is a simple calming technique of breathing in four equal parts: inhale, hold, exhale, and hold, each for a count of about four. The even, deliberate rhythm slows breathing and steadies the nervous system. It's used by everyone from athletes to first responders to stay calm under pressure. It's easy to remember and can be done anywhere.
