About 4-7-8 Breathing

Developed by Dr Andrew Weil, 4-7-8 breathing is based on the ancient yogic technique of pranayama. It works by activating your parasympathetic nervous system - the body's natural "rest and digest" response - which directly counters the fight-or-flight adrenaline response.

How to Do It

1. Exhale completely through your mouth, making a whoosh sound
2. Inhale quietly through your nose for 4 seconds
3. Hold your breath gently for 7 seconds
4. Exhale slowly through your mouth for 8 seconds
5. That's one round. Repeat for your chosen number of rounds

Why It Works

The 4-7-8 ratio matters. Inhaling for 4 seconds fills your lungs. Holding for 7 allows oxygen to saturate your bloodstream. Exhaling for 8 - longer than the inhale - signals your vagus nerve to slow your heart rate and reduce adrenaline production.

How Many Rounds?

• 4 rounds - Standard practice. Good for general stress relief throughout the day
• 6-8 rounds - For heightened anxiety or panic. The extended practice deepens the parasympathetic response
• 8-12 rounds - For sleep induction. The extended rhythm reliably induces drowsiness

Start with 4 rounds and increase gradually. The effect deepens with practice - your nervous system learns the pattern and responds faster over time.

When to Use

• Before sleep - Use 6+ rounds when lying in bed
• During anxiety - Use 4-6 rounds when you feel panic rising
• Before stressful events - 4 rounds before a difficult conversation or presentation
• Throughout the day - Even 2 rounds as a "micro-reset" between tasks can lower cortisol

Tips

• Keep your exhale slow and controlled - the longer exhale is what triggers the relaxation response
• Don't force the hold - it should feel comfortable, not straining
• Practise twice daily. After 4-6 weeks, your body will shift into calm more quickly
• Safe for most people. If you have respiratory conditions, start with fewer rounds
