Fitness, Wellness, Stress Management Practice Test

Box breathing is defined by four equal parts: inhale, hold, exhale, and hold. Each phase lasts the same amount of time, creating a steady, square-like rhythm. This equal-interval pattern is what makes the technique distinctive, because it trains you to regulate your breathing with precision rather than rushing. Maintaining a consistent pace helps calm the nervous system, slow the heart rate, and activate the parasympathetic branch, which promotes relaxation and focus. It’s typically practiced awake in calm settings, not as rapid or intense breathing, and it isn’t something done during sleep.
