What is Box Breathing (Navy SEAL Protocol)?

Inhale 4 counts, hold 4, exhale 4, hold 4. Used by Navy SEALs to maintain composure under extreme stress. The holds between breaths stimulate the vagus nerve and engage the parasympathetic nervous system. Works in seconds.

How do you do Box Breathing (Navy SEAL Protocol)?

  1. 1.Inhale through your nose for 4 counts (counting at roughly 1 second per count)
  2. 2.Hold your breath for 4 counts. Keep your throat open — don't clamp down
  3. 3.Exhale slowly through your nose (or mouth) for 4 counts, emptying your lungs completely
  4. 4.Hold empty for 4 counts. This is the hardest part and the most powerful — the empty hold maximizes CO2 and vagal activation
  5. 5.Do 4-8 rounds (2-4 minutes). Use BEFORE stressful situations (meetings, difficult conversations, performances) not just during them. It's more effective as prevention than rescue

How long does it take?

2-4 minutes per session.

Is it hard to start?
