Do you have asthma? If so, you’ll be aware there are several common triggers that can cause asthma symptoms to flare up.
Here are some of them:
- Dander — the fur, skin or scales from household pets
- Moulds, which are caused by moisture in your home
- Dust mites living in your bedding or carpets
- Pollens from plants
- Other triggers like chemicals, smoke, perfumes and cold air.
So, of course, it’s important you know your triggers and manage them as best you can.
In this article I explain how the way you heat and cool your home can impact your asthma. I also explain why a home ventilation system just might be a good choice.
Suggestions from the Asthma Foundation
The Asthma Foundation offers these recommendations for heating and cooling your home:
- Choose radiant heating because it doesn’t collect and circulate dust
- Avoid open fires because they generate smoke
- Avoid fan-forced ducted heating because it circulates dust
- Avoid un-flued gas heaters because they produce indoor air pollutants, including nitrogen dioxide and carbon monoxide. They also produce water vapour that can increase the growth of moulds and dust mites.
- Choose refrigerated reverse-cycle systems because they remove moisture from the air
- Avoid evaporative cooling systems because they create humidity.
Home ventilation systems tick all the boxes
Looking at the Asthma Foundations’s suggestions, you’ll see there are two main triggers they suggest for you to avoid: pollutants and moisture.
How a home ventilation system works
Home ventilation systems are designed to warm and cool your home and remove toxins from the air. They are installed within the roof space of your home. Air is drawn from either the roof space, where it’s dry and warm, or from outside.
Removal of toxins
Incoming air is filtered of toxins, like pollens and dust, and distributed throughout your home. The force created by the introduction of filtered air effectively expels existing stale air (along with toxins) from your home through cracks around your windows and doors or through specially-fitted vents.
Removal of moisture
Mould, bacteria and dust mites thrive on moisture. And an average person creates 30 litres of moisture a day by performing everyday tasks like cooking, showering and washing clothes.
When it is cold, a home ventilation system will draw air from your roof space. The air is warm and dry up there because your roof traps the warmth generated by the sun. So, when this warm, dry air is distributed throughout your home, not only are toxins driven out, moisture is driven out too.
So, if you’re asthmatic, home ventilation systems are ideal because they drive out the toxins and moisture from the air that can trigger asthma symptoms
