“Just take a deep breath.”

If you’ve ever been in the middle of an anxiety spiral and someone offered this advice, you probably wanted to scream. When your heart is pounding and your thoughts are racing, “just breathe” feels about as helpful as “just relax.”

But here’s the thing — they’re not entirely wrong. They’re just missing some important details.

Breathing really is one of the fastest ways to calm anxiety. The problem? Most people have no idea how to breathe in a way that actually flips the switch on your nervous system.

I’ve spent 15 years as a psychiatric nurse practitioner working with anxious patients, and I’ve watched breathing techniques genuinely change lives. But I’ve also learned they need to be taught properly — and adjusted for bodies that have logged six or more decades of life.

So Why Does Breathing Actually Work?

Here’s what’s fascinating: your breath is the only automatic body function you can take over consciously. Your heart rate, digestion, hormones — those just happen. But breathing? You’re in the driver’s seat whenever you want to be.

And your breath talks directly to your nervous system. Shallow, quick breaths (which happen automatically when you’re anxious) tell your brain danger! Slow, deep breaths tell your brain all clear.

The vagus nerve is the messenger here. It’s the longest nerve in your body, running from your brain all the way through your face, throat, heart, and gut. When you breathe a certain way, you wake up this nerve and switch on your parasympathetic nervous system — that’s your body’s “rest and digest” setting.

This isn’t woo-woo stuff. It’s biology. Change your breath, change your nervous system. It’s that direct.

A Few Things to Know If You’re Over 60

Before we get into the techniques, let’s talk about something important: breathing exercises sometimes need a little tweaking as we get older.

Lung capacity naturally decreases over time. Your diaphragm might not be as springy as it once was. And if you’re dealing with COPD, asthma, or heart issues, holding your breath or breathing super deeply might not feel great.

None of this means these techniques won’t work for you — they absolutely will. You just might need shorter holds or gentler timing. I’ll give you modifications for each one.

And if you have any respiratory or heart conditions, run these by your doctor first. Better safe than sorry.

The 4-7-8 Breath (aka “The Relaxing Breath”)

Dr. Andrew Weil developed this one, and it’s a favorite of mine. That long exhale is like a lullaby for your nervous system.

Here’s how to do it:

Sit somewhere comfortable with your back supported (or lie down if you prefer). Rest the tip of your tongue against the little ridge right behind your upper front teeth — keep it there the whole time.

Breathe out completely through your mouth with a soft “whoosh” sound. Then close your mouth and breathe in quietly through your nose for 4 counts. Hold for 7 counts. Exhale through your mouth (another whoosh) for 8 counts.

That’s one cycle. Do four total.

If 7 counts feels like too much: Try 4-4-6 instead (in for 4, hold for 4, out for 6). What matters most is that your exhale is longer than your inhale. You can work your way up over time.

Belly Breathing (Diaphragmatic Breathing)

Here’s a secret: a lot of us breathe into our chests without even realizing it. This shallow breathing can actually keep anxiety humming along in the background. Belly breathing goes deeper and sends a much stronger “calm down” signal to your brain.

Here’s how to do it:

Lie on your back with your knees bent, or sit comfortably. Put one hand on your chest and the other on your belly, right below your ribs.

Breathe in slowly through your nose and focus on making your belly hand rise — your chest hand should barely move. Then exhale slowly through pursed lips and let your belly naturally fall.

Keep going for 5-10 minutes.

Why it works: When your diaphragm drops down (pushing your belly out), it makes more room for your lungs to really expand. More oxygen, more vagus nerve stimulation, more calm.

Box Breathing (Square Breathing)

Navy SEALs use this one. So do paramedics and firefighters. The equal counts make it easy to remember even when your brain feels scrambled.

Here’s how to do it:

Breathe in for 4 counts. Hold for 4 counts. Breathe out for 4 counts. Hold for 4 counts.

Repeat 4-6 times.

If that last hold feels weird: Just skip it. Breathe in for 4, hold for 4, breathe out for 4, then go right into the next inhale. You’ll still feel the benefit.

Which Technique for Which Moment?

When anxiety hits hard: Box breathing or 4-7-8. These can interrupt the spiral quickly.

For everyday stress: Belly breathing for 10 minutes, morning and evening.

When you can’t sleep: 4-7-8 while lying in bed. Honestly, a lot of my patients drift off before they finish four rounds.

Before something stressful: Box breathing right before the doctor’s appointment, the difficult conversation, the family gathering.

The Real Secret to Making This Work

Here’s where most people go wrong: they only try breathing techniques when they’re already in full-blown anxiety mode. By that point, your nervous system is so revved up that calming down takes a while.

The magic happens with regular practice. When you do these techniques every day — even when you feel fine — you’re basically training your nervous system to relax on command. Over time, you’ll find you can calm down faster and catch anxiety before it snowballs.

Start simple: 5 minutes of belly breathing when you wake up. Add 4-7-8 before bed. Give it a few weeks and see what shifts.

Your breath is always with you. It’s free. No side effects. No prescription needed. That’s exactly the kind of tool I love sharing with my patients.
