Why Breathwork Works for Anxiety

Anxiety activates your sympathetic nervous system the fight-or-flight response.

This causes:

• Rapid breathing

• Increased heart rate

• Muscle tension

• Heightened alertness

Breathwork works because it activates the parasympathetic nervous system, which tells your body:

“You’re safe. You can relax.”

Slow, intentional breathing:

• Lowers cortisol

• Reduces heart rate

• Improves emotional regulation

• Interrupts panic cycles

This isn’t spiritual hype it’s biology.

When to Use Breathwork for Anxiety

Breathwork is especially effective when anxiety shows up as:

• Racing thoughts

• Panic or impending doom

• Chest tightness

• Restlessness

• Overwhelm or emotional spirals

It works best before anxiety peaks, but it can also bring you down once panic starts.

Technique #2: Extended Exhale Breathing (Best for Chronic Anxiety & Overthinking)

Exhale > Inhale = safety signal.

How to Do It

1. Inhale through your nose for 4 seconds

2. Exhale slowly through your mouth for 6–8 seconds

3. Keep the breath smooth and relaxed

Repeat for 3–6 minutes.
