Box breathing is a simple relaxation technique designed to reduce stress and promote calmness through controlled breathing. It follows a 16-second cycle:

– Inhale for 4 seconds
– Hold the breath for 4 seconds
– Exhale for 4 seconds
– Hold for 4 seconds

This pattern forms a “box” shape, making it easy to visualise and follow. The cycle can be repeated for 3–5 minutes.

– Slows heart rate
– Lowers blood pressure
– Reduces stress hormone levels
– Promotes relaxation and mental clarity

Box breathing can be used anytime you need to reset or manage stress, including:

– Before presentations or exams
– During a busy day (e.g. a lunchtime reset)
– As part of chronic pain management
– Before bed to help unwind and prepare for sleep

– Sit upright in a comfortable chair
– Keep your feet flat on the ground
– Rest your hands in your lap
– Maintain a relaxed posture to allow for deep breathing
– Start in a quiet, low-stress environment while learning the technique

The controlled breathing and brief breath holds allow carbon dioxide levels to rise slightly in the blood. This stimulates the parasympathetic nervous system (your “rest and digest” system), helping to slow the heart rate and create a sense of calm and relaxation.

Physiotherapists and Exercise Physiologists often incorporate box breathing into treatment plans to support patients in managing chronic pain, stress, and anxiety associated with long-term conditions.
