Respiratory health in a changing climate

Respiratory health in a changing climate: learn how rising pollution and extreme weather affect respiratory health – and what you can do about it.

One breath changed everything

I never thought much about the air I breathed – until it started fighting back.

It was a hot summer afternoon, the kind where you can feel the heat bouncing off the pavement.

I was walking my dog, nothing unusual, until I started coughing. First it was dry.

Then came the tightness in my chest. And suddenly, breathing felt like work.

Turns out, I wasn’t just “overheated.”

The air quality that day was rated as unhealthy due to high levels of ground-level ozone and wildfire smoke blowing in from hundreds of miles away.

That moment made me realize something I’d been ignoring: our environment is changing, and my body can feel it – especially in my lungs.

How climate change is affecting our breathing

Let’s break it down. Climate change doesn’t just mess with the planet – it messes with people.

And respiratory health is one of the first things to take a hit.

Here’s how it’s happening:

More wildfires = more smoke

With rising global temperatures, wildfire seasons are getting longer and more intense.

Even if you don’t live near a forest, the smoke can travel thousands of miles, filling the air with fine particulate matter (PM2.5) – tiny particles that go deep into the lungs.

Hotter days = dirtier air

High temperatures increase ground-level ozone, a major component of smog.

This isn’t the good ozone way up in the atmosphere.

This one irritates the lungs and can trigger asthma attacks, especially in children and older adults.

Allergy season? Try allergy year

Climate change is also making pollen seasons longer and more intense.

That means more sneezing, wheezing, and itchy eyes for anyone with allergies or asthma.

Stronger storms = mold & moisture

Floods and hurricanes leave behind more than damage.

They create damp environments where mold and mildew thrive – another trigger for respiratory problems.

Living with sensitive lungs in an unpredictable climate

Since that day, I’ve had to be more aware of my own breathing.

I’ve always been relatively healthy, but now I pay attention to things I used to ignore – like air quality alerts, pollen counts, and humidity levels.

Here’s what I’ve learned the hard way: you don’t have to have a diagnosed condition to be affected.

Climate change is putting pressure on all of our lungs – especially if you live in cities or near high-traffic areas.

Who’s most at risk?

While anyone can feel the effects of poor air, some groups are more vulnerable:

• Children (their lungs are still developing)
• Seniors (often with pre-existing health conditions)
• People with asthma or COPD
• Low-income communities, who often live in high-pollution zones
• Outdoor workers and athletes exposed to the elements daily

According to the American Lung Association, more than 40% of Americans live in counties with unhealthy air.

That’s nearly 137 million people.

How to protect your respiratory health (Even when the air isn’t on your side)

It’s easy to feel powerless, but the truth is – there’s a lot we can do to protect ourselves and our families.

Here are a few tips that made a real difference in my life:

1. Check the air quality index (AQI)

Before heading out, I check apps like AirVisual, IQAir, or even Google Weather.

If the AQI is above 100, I take precautions – especially during exercise.

2. Wear a mask on high pollution days

Yep, I still keep my KN95s. They’re not just for pandemics – they filter out fine particles from smoke, smog, and dust.

3. Use an air purifier indoors

I invested in a good HEPA air purifier for my living room and bedroom. It helps keep the indoor air clean when the outside air gets ugly.

4. Keep windows closed on bad days

I love fresh air as much as anyone, but when pollution or allergens are high, I seal the windows and turn on filtered AC instead.

5. Add some green

Plants like snake plants, peace lilies, and spider plants can help improve indoor air quality – plus, they make your space look alive.

Small lifestyle changes that help your lungs stay strong

Beyond air quality, I also started being more mindful of my day-to-day habits:

• I swapped chemical-heavy cleaners for non-toxic options.
• I quit burning scented candles (sorry, ambiance) and switched to essential oils.
• I started using fragrance-free laundry detergent.
• And I finally made that long-overdue doctor appointment to check my lung function.

It’s all about reducing what I call “invisible irritants.” The little things that add up.

Why this isn’t just a “personal health” issue

Sure, I made changes in my routine.

But that only goes so far. The truth is, we need broader solutions – and fast.

Climate change is a public health issue.

Period. If our air is making us sick, then clean air becomes not just a comfort, but a human right.

Supporting clean energy, better public transportation, and stronger air quality regulations are no longer just political topics.

They’re survival tools.

You don’t have to be a climate scientist to care about breathing

Breathing should be effortless. Invisible. Natural.

But in today’s climate, it’s becoming a conscious choice.

Every inhale matters.

If you’ve been feeling more congested, coughing more than usual, or just waking up with that weird pressure in your chest – it might not just be you.

It might be the air.

And while we can’t control the weather, we can protect our lungs, support each other, and push for change that puts health first.
