Why is it called Box Breathing?

It's called "box" or "square" breathing because each of the four phases (inhale, hold, exhale, hold) has equal duration, creating a square pattern when visualized.

How is this different from 4-7-8 breathing?

Box Breathing uses equal counts (4-4-4-4) and includes breath holds at empty lungs, making it better for focus and performance. 4-7-8 has unequal counts and emphasizes the exhale for deeper relaxation and sleep.

Can I do more than 4 counts per phase?

Yes! Advanced practitioners use 5-5-5-5 or even 6-6-6-6. Start with 4 and gradually increase as you build lung capacity and comfort.

Why do Navy SEALs use this technique?

SEALs need to maintain peak performance under extreme stress. Box Breathing calms the nervous system while maintaining alertness - unlike deeper relaxation techniques that might reduce vigilance.

How many cycles should I do?

Start with 4-5 cycles (about 2-3 minutes). You can do more if needed, but most people feel significantly calmer after just a few cycles.

Is it safe to hold my breath?

Yes, the 4-second holds are very safe for healthy individuals. If you have respiratory issues or feel uncomfortable, skip the holds or reduce to 2-3 seconds.

Quick Answer
