How to reduce asthma triggers at home
Find out what triggers your asthma.
The best way to reduce asthma triggers is to find out what your triggers are. Don't purposely put yourself at risk of an asthma attack if you think that something may trigger it.
Instead, think back to times when your asthma started to flare up. Is there any relationship between all of the events? Maybe your asthma mainly occurred in a specific part of the day, or a specific environment.
