Environmental factors can trigger asthma

FALLBROOK - Though many are likely familiar enough with asthma to recognize it’s a respiratory disease that affects millions of people across the globe, few may know the role that environmental triggers play with regard to asthma.

Indoor allergens and irritants often trigger asthma attacks, but fortunately such triggers can be controlled by people who take a proactive approach to reducing their exposure to environmental triggers like those listed below.

Secondhand smoke

The smoke from a cigarette, cigar or pipe contains more than 4,000 substances, some of which are cancerous compounds. In addition to triggering asthma attacks in those already diagnosed with the condition, secondhand smoke is a risk factor for asthma among preschool-aged youngsters. Thanks to their diminutive statures, kids breathe more rapidly than adults, and that means they take in more secondhand smoke when around smokers than older kids or fully grown adults. But secondhand smoke is harmful to adults as well, triggering asthma attacks and increasing their risk for a variety of health conditions. Parents should not let anyone smoke near their children, and adults with older kids should avoid smokers as much as possible.

Dust mites

Tiny, invisible bugs that feed on dead skin, dust mites can be found in mattresses, pillows, carpets, stuffed toys, and clothes, among other things. Individuals who are allergic to dust mites might be susceptible to asthma if they come in contact with dust mites’ body parts and droppings, and such exposure can trigger asthma in youngsters who have not previously exhibited symptoms of the condition. Bedding should be washed in hot water at least once per week and dried completely, and dust proof covers should be used on pillows and mattresses. Vacuum carpets and furniture once per week. Also, parents can reduce their kids’ risk of asthma attacks by only buying stuffed toys that can be washed in hot water.

Molds

Molds live on plant and animal matter and can be found nearly anywhere that moisture is present. Inhaling mold spores, which continually float through indoor and outdoor air, can trigger an asthma attack. Mold problems in a home should be addressed immediately. Mold on hard surfaces can be removed with soap and water, and the surfaces should be allowed to dry completely before being put to use again. Use exhaust fans in rooms such as the kitchen and bathroom, where fans can be used both during and after showering. Some mold growths might be a byproduct of leaks, so check pipes for leaks when any mold is found near sinks, tubs or showers.
