Box breathing, also known as square breathing or 4-4-4-4 breathing, is a deep-breathing technique used to regulate the autonomic nervous system. It is famously used by Navy SEALs to maintain composure and focus in high-pressure situations. 

How to Practice Box Breathing

The technique follows a simple four-step cycle, typically using a count of four for each stage: 

1. Inhale: Breathe in slowly through your nose for 4 seconds.
2. Hold: Keep your lungs full for 4 seconds.
3. Exhale: Release all air slowly through your mouth for 4 seconds.
4. Hold: Keep your lungs empty for 4 seconds before the next inhale. 

Benefits for Wellness

Box breathing offers immediate and cumulative psychological and physiological advantages: 

• Stress & Anxiety Relief: It activates the parasympathetic nervous system (the “rest and digest” response), which counteracts the “fight or flight” mode.
• Mental Clarity: By focusing on the rhythmic counting, practitioners can clear mental clutter, leading to improved concentration and cognitive performance.
• Emotional Regulation: Regular practice helps stabilize mood swings and increases resilience to future stressors.
• Better Sleep: Practicing before bed helps quiet racing thoughts and physically relaxes the body, making it easier to fall asleep. 

Impact on Longevity

While not a direct “anti-aging” cure, box breathing supports longevity by mitigating the long-term damage caused by chronic stress: 

• Cardiovascular Health: Consistent practice can lower blood pressure and slow the heart rate, reducing strain on the heart and the risk of hypertension.
• Heart Rate Variability (HRV): It enhances HRV, a key indicator of autonomic health and a predictor of overall mortality and fitness.
• Gene Activation & Inflammation: Research suggests that relaxation techniques like box breathing can activate genes associated with energy metabolism and insulin secretion while decreasing genes linked to inflammation and stress.
• Cortisol Reduction: By manually lowering cortisol (the primary stress hormone), box breathing helps prevent the wear and tear that chronic stress causes on every bodily system.
