Most people feel calmer within 60-90 seconds. For sleep improvements, practice daily for 2-4 weeks.

Is 4-7-8 breathing safe for everyone?

Yes, it's safe for most people. If you have respiratory conditions, start slowly and consult your doctor.

Can I do it more than 4 cycles?

Why hold breath for 7 seconds?

The hold allows oxygen to fully saturate your bloodstream and increases CO2, which triggers the relaxation response.
