Your dirty bed sheets
istock/Mitshu There’s something delicious about falling into a cozy bed after a long day, but the icky details about dust mites dwelling in your bed sheets may leave you opting for the couch instead. According to refinery29.com, the average person sheds roughly half an ounce of dead skin every week, which stays in your sheets and becomes prime feeding material for dust mites. The fecal matter and other debris they leave behind can lead to some scary effects, exacerbating eczema, seasonal allergies, skin irritations, and more. (Here are other important things allergists wish you knew.) To keep these critters out of your snooze space, be sure to wash your bed sheets in 60-degree water at least once a week.
Contaminated heating and cooling vents
istock/BanksPhotos If all of a sudden you begin feeling extra allergenic or sick for no apparent reason, contaminated heating and cool ducts may be to blame. The Environmental Protection Agency explains that a little bit of dust in these pipes is normal and largely harmless, but in some cases mold and other debris can build up, wreaking havoc on your health. Experts are still trying to determine whether or not cleaning the ducts prevents these health problems, but the majority agree that removing mold and other toxins from pipes that have become highly contaminated is a smart move. All homeowners should know about these critical maintenance moves.
