Your heart is racing. Your thoughts are spiraling. Everything feels wrong.

You can’t think your way out of anxiety. But you can breathe your way out.

Here are 5 techniques that actually work.

Why Breathing Works for Anxiety

Anxiety activates your sympathetic nervous system — fight or flight.

Slow, controlled breathing activates your parasympathetic nervous system — rest and digest.

You can’t be in both states simultaneously. Controlled breathing literally forces your body to calm down.

This isn’t woo-woo. It’s physiology.

1. Box Breathing (The Navy SEAL Technique)

Best for: Acute anxiety, panic, high-stress situations

Used by Navy SEALs before operations. If it works for them, it works for your email anxiety.

How to do it:

  1. Inhale for 4 seconds
  2. Hold for 4 seconds
  3. Exhale for 4 seconds
  4. Hold for 4 seconds
  5. Repeat 4-8 cycles

Why it works: The breath holds activate your vagus nerve, which triggers relaxation.

Time to calm: 2-4 minutes

2. 4-7-8 Breathing (The Relaxation Breath)

Best for: General anxiety, trouble sleeping, racing thoughts

Developed by Dr. Andrew Weil. Simple, effective, fast.

How to do it:

  1. Inhale through nose for 4 seconds
  2. Hold for 7 seconds
  3. Exhale through mouth for 8 seconds
  4. Repeat 4 cycles

Why it works: The long exhale activates relaxation response. The hold creates CO2 build-up which has a calming effect.

Time to calm: 1-2 minutes

3. Physiological Sigh (The Fastest Method)

Best for: Immediate relief, mid-conversation anxiety, quick reset

Stanford research shows this is the single most effective breathing pattern for instant calm.

How to do it:

  1. Double inhale through nose (big breath, then small top-up breath)
  2. Long exhale through mouth
  3. Repeat 2-3 times

Why it works: The double inhale maximally inflates your lungs, which triggers your vagus nerve. The long exhale dumps CO2.

Time to calm: 30 seconds

4. Diaphragmatic Breathing (Belly Breathing)

Best for: Chronic anxiety, daily stress management, prevention

The foundation of all breathing techniques.

How to do it:

  1. Place hand on belly
  2. Inhale through nose — belly rises
  3. Exhale through mouth — belly falls
  4. Chest stays relatively still
  5. Aim for 6 breaths per minute

Why it works: Most anxious people breathe shallowly from their chest. Belly breathing engages the diaphragm and activates relaxation.

Time to calm: 5-10 minutes (but builds long-term resilience)

5. Alternate Nostril Breathing

Best for: Mental clarity, balancing energy, meditation prep

A yoga technique with real benefits.

How to do it:

  1. Close right nostril with thumb
  2. Inhale through left nostril for 4 seconds
  3. Close left nostril with finger
  4. Exhale through right nostril for 4 seconds
  5. Inhale through right nostril for 4 seconds
  6. Switch and exhale through left
  7. Repeat 5-10 cycles

Why it works: Balances left and right brain activity. Creates focus through the physical engagement.

Time to calm: 3-5 minutes

The Common Mistakes

Breathing too fast

Slow down. Count properly. Most people rush.

Forcing the breath

It should feel natural, not strained. If you’re gasping, you’re doing it wrong.

Not exhaling fully

The exhale is where the magic happens. Make it long and complete.

Giving up too early

Give each technique at least 4-8 cycles before deciding it’s not working.

Only using during crisis

These work best when practiced daily, not just during emergencies.

Building a Daily Practice

Prevention beats intervention.

Morning: 2 minutes of diaphragmatic breathing before getting up Afternoon: Box breathing when you feel energy dipping Before bed: 4-7-8 breathing to wind down

5 minutes a day builds your stress resilience.

Using an App to Guide You

Remembering which technique is which, timing your breaths, knowing when to switch — it’s a lot.

I built BreathingExercises to handle this. Select a technique, follow the visual guide, done.

Also check out MeditationApp for guided sessions that combine breathing with meditation.

When Breathing Isn’t Enough

Breathing exercises are a tool, not a cure.

If you experience:

  • Anxiety that prevents normal life
  • Panic attacks multiple times a week
  • Breathing exercises making things worse
  • Physical symptoms (chest pain, etc.)

Talk to a professional. There’s no shame in getting help.

FAQ

How fast do breathing exercises work? The physiological sigh works in 30 seconds. Most techniques take 2-5 minutes for noticeable calm.

Can breathing exercises help panic attacks? Yes. The physiological sigh or box breathing can interrupt a panic attack. But practice when calm so it’s automatic when you need it.

How often should I do breathing exercises? Daily practice of 5-10 minutes builds resilience. Plus use them as needed when stressed.

What if I feel dizzy? You’re probably hyperventilating. Slow down, breathe naturally for a moment, then try again with less intensity.

Can these replace medication? For mild-moderate anxiety, sometimes. For severe anxiety, they’re a supplement, not a replacement. Consult your doctor.
