Box breathing. 4 in, 4 hold, 4 out, 4 hold.
The quick science:
• Slows your heart rate and switches on the parasympathetic nervous system — your body’s built-in brake pedal on stress
• Popularized by former Navy SEAL Commander Mark Divine, who used it in SEAL training to stay calm under pressure (he breaks it down in *Unbeatable Mind*)
• James Nestor covers it in *Breath*: slow breathing is the fastest lever you have on your nervous system
The military uses it to come down after adrenaline spikes and fall asleep at night. You can use it before the hard conversation, after the long day, or mid-corn-maze in a Power Ranger suit. 😄
Follow along for one round with me — your nervous system will thank you. Save this for the next time your brain won’t shut off.
