To Keep Your Bedroom Healthy, Keep on Dusting

It’s not your housekeeping skills, really. That layer of dust on your bookshelf or behind your nightstand is part of everyday life, not a sign of neglect. But it can be a real health concern if left unchecked.

Dust is made up of microscopic particles like skin flakes (from humans and pets), fibers from furniture and fabric, and tiny critters like dust mites. According to allergists, the average American home collects about 40 pounds of dust each year—and most of it ends up where we spend the most time: indoors.

In fact, the Environmental Protection Agency (EPA) estimates people spend about 90% of their lives indoors, making dust a significant contributor to indoor air pollution. For those with allergies or asthma, even a small buildup can trigger symptoms.

So what can you do about it? Start with your bedroom. According to EPA spokesperson Molly Hooven, targeting your sleeping space makes the most sense—after all, we spend a third of our lives in bed.

Here are a few tips to help reduce dust where it matters most:

Minimize Clutter
Dust mites love clutter. The more surfaces and fabric items you have, the more places dust has to settle. Consider removing extra furniture or decorative items that collect dust easily.

Vacuum Carpets with a HEPA Filter
A vacuum cleaner equipped with a HEPA filter can help capture even the tiniest dust particles. Vacuum your bedroom floor regularly to remove settled dust mites and dander.

Wipe Surfaces with a Damp Cloth
Dry dusting just spreads particles around. Use a damp cloth or cleaning polish to effectively trap and remove dust from nightstands, dressers, headboards, and other electronic devices.

Wash Bedding in Hot Water
Use water that’s at least 140 degrees Fahrenheit to kill dust mites lurking in your sheets and pillowcases. Wash bedding regularly, especially pillow covers and mattress protectors.

Freeze Stuffed Animals
If your child’s favorite plush toy can’t be washed, place it in a plastic bag and stick it in the freezer for 24 hours. The cold will eliminate dust mites.

Close Closet Doors
Keeping closets shut helps limit the amount of dust that spreads into your bedroom from clothing, shoes, and stored items.

While it’s impossible to eliminate dust, a few mindful habits can make your bedroom healthier, and a whole lot more comfortable.

So yes, keep dusting. Your lungs (and your sinuses) will thank you.
