The Physiology of Breath
Why does this work? It activates the Vagus Nerve. This long nerve runs from your brain to your gut and controls your parasympathetic nervous system. Slow, rhythmic exhalations signal safety to the brain, lowering cortisol and heart rate within minutes. It is biologically impossible to stay stressed while breathing at this cadence.⚕️ Medical Disclaimer & Methodology

💡 Frequently Asked Questions
How long does it take to see results?
Most sleep hygiene interventions require at least 7-10 days of consistent application before your circadian rhythm adapts. Do not give up if you don’t see immediate results after one night.
Can I combine this with medication?
If you are currently taking prescription sleep aids (like Ambien or Lunesta), consult your doctor before trying natural supplements or drastic routine changes to avoid interactions.
Is this safe for children?
While behavioral changes (like limiting screen time) are safe for all ages, supplement recommendations in this article are intended for healthy adults only.
