Living withasthmameans you’re especially sensitive to changes in the air you breathe. There are lots of factors that can aggravate your lungs, like dust andpollution. It turns out, even the temperature and humidity of the air around you could affect how you feel.
Here’s how to pick the best temperature for your home and how to deal with situations where you have to be infreezingor scalding outside temps.

The best temperature and humidity for asthma
If you’re one of the25 millionAmericans with asthma, finding the right room temperature is an important part of feeling your best.
Here’s the optimal environment for folks with asthma:
There’s a little more to it than that, though. We dug into what science has to say about the best room temperature for asthma.
The ideal room temperature if you have asthma
Temperature extremes can be a trigger for asthma. Doesn’t matter if it’s too hot or too cold. If it’s far enough from the happy medium, you might notice worsening symptoms.
Since asthma varies from person to person, it’s hard to pin any universal nope-zones on the thermostat. If you experience pretty mild asthma, minor temperature changes prob won’t be a big problem. However, if your asthma is more severe, closely monitoring your room temperature can be an important part of managing your condition.
Asmall 2012 studysuggested that68 to 71°F (20 to 21.6°C)is the safest temperature range for folks with asthma. That works out, because 68 to 72°F (20 to 22°C) is what’s literally considered “room temperature”.
Humidity seems to be less important, but it’s still worth considering. As arule of thumb, air humidity levels above/below30% to 50%could be an asthma trigger. Why else would humidity matter? High indoor humidity levels can lead to dust mites and mold. (Those are two big asthma triggers.)
How to keep your home asthma-friendly
Keeping your indoor rooms at these levels is made a lot easier with the right tools.
The link between air temperature and asthma
Asthma’s all in the airways. It can be triggered both by extremes of temperature and sudden shifts in air temperature.
How much is too much?Some studiesshow that temp changes greater than 41°F (5°C) can cause probs for the respiratory systems of folk with asthma.
Protecting yourself from extreme weather if you have asthma
Indoor temperatures are controllable, but mother nature doesn’t have a thermostat. Here’s how to keep yourself safe.
When it’s hot
Stay indoors when the air quality stinks.Yes, even if you’ve spent enough time inside during the pandemic for a whole lifetime. If you check local levels of pollen/pollution and find them less-than-friendly, give yourself a 1-day staycation. Avoiding harsh outside environments is a possible way to swerve potential triggers.
Keep loose, light clothing.When it’s hot, you sweat, right? That can dehydrate you, and dehydration can trigger your asthma. Dress for the heat, which means loose, light, even moisture-wicking clothing.
When it’s cold
Wear a face mask or scarf.Turns out, masks aren’t just helpful forpreventing the spreadof a pandemic. Keeping your mouth and nose covered helps keep the air in your lungs humid and moist. That’s beneficial for asthma symptoms.
Prep for the cold.Just like the right clothes can help you in the heat, wearing cold-weather gear when it’s cold out is important. It keeps you warm, which can help reduce the likelihood of triggering your asthma.
General advice
Carry your rescue inhaler.This prob isn’t news to you, but it doesn’t hurt to reiterate. If you live with asthma, you should try toalwayscarry your rescue inhaler with you. Just in case.
Stick to your treatment plan.Always try to follow your doctor’s plan for management of your asthma. Chances are, planning for temperature and humidity changes are something they’ve addressed.If your treatment plandoesn’tseem to mention air temperature or humidity, speak with your doctor for personalized advice.
Other environmental factors
Air temperature and weather extremes aren’t the only considerations you need to take. There are a few other asthma triggers lurking in the air you should be aware of.
When to call a doctor
Noticing that you’re wheezing, feeling short of breath, or chest tightness? If you haven’t been diagnosed with asthma but think you could be experiencing asthma, talk with your doctor about your symptoms.
When to call your doctor right away
Keep an eye out for any of these scenarios. Let your doctor know ASAP if you’re:
The optimum air temperature if you have asthma is68 to 71°F (20 to 21.6°C), with humidity levels at30% to 50%. Indoor air temperature can be controlled with a variety of tools like AC and extractor fans.
Weather extremes can worsen asthma symptoms, but there are things you can do to protect yourself. Talk with your doctor if you’re noticing new asthma symptoms, or if you’re not sure how to manage your existing symptoms. They can give you personalized advice to help manage your condition.
