Physiological sigh

Two short inhales through the nose, one long exhale through the mouth. Lowers acute stress within 1–3 cycles. Pull this out before stressful meetings.

Box breathing

Inhale 4, hold 4, exhale 4, hold 4. Five minutes daily lowers heart rate and improves HRV.

Slow nasal breathing

5–6 breaths per minute through the nose for 10 minutes. Improves vagal tone and stress resilience.
