Is cool air a better environment for people with asthma or allergies?

Asked by dxs (11557 points ) April 14th, 2014

Let’s say someone I know has asthma or allergies and he claims that because of his asthma, his room needs to be constantly very cool. I understand a need for good air quality. Does the temperature of the air have a factor in this as well?

Humidity can trigger asthma, as obviously unfiltered air can, too.

Conditioned air can help prevent indoor asthma attacks, as it cleans, cools and dries the air. Conditioning the air can also help keep mold and pollen spores to a tolerable level.

Humid air @SpatzieLover points out can trigger asthma because humid air can carry more airborn pollen and irritants than dry air. Conversely cool air causes many to keep their windows closed and that traps these irritants indoors where they can cause more discomfort. One of the reason so many retirees opt for the dry warmer climes like AZ where they can keep windows open and fresh air flowing.

I don’t have asthma but…my allergies get worse when it rains, especially in the spring because of mold spores. Yes, I feel much better breathing cooler air and hate summer heat when you feel like there is a heaviness to the air. I concur with the above jellies.

As Coloma mentioned, warm moist air is a field day for mold spores to grow.

That is one of my chief allergens also, so I definitely need AC in the warm muggy days of summer.

Thank you for the responses!
Humidity isn’t correlated to the temperature of the air, is it? @Cruiser mentioned Arizona, which is still warm, but dry.

Air temperature for an asthmatic ideally would be kept not too hot and not too cold. Temperature extremes can trigger attacks. Ideally indoor air temperature would be kept at a constant to keep the asthma well controlled.

@Cruiser mentioned Arizona for asthma, however, @dxs, too dry and too warm of air is also not ideal for asthmatics.

The best places to reside are those with controlled climates, such as Hawaii and specific areas of Florida and California, where climates and humidity are at a near constant.

When one does not live in these “ideal” locations, (and even in the ideal locations, if pollen or spore counts increase), one needs to take precautions to control his/her asthma. That includes controlling the indoor air temperature and air quality, reducing stress, and avoiding triggers (cleaning chemicals, cooking odors, smoke, etc).
