Illinois, You NEED To Wash Your Pillowcase Tonight—Here’s Why

We’ve all had that moment—walking into a questionable bathroom at a rest stop somewhere off I-55 or Route 66 and immediately regretting it. But here’s the gross truth: your pillowcase might be harboring more bacteria than that gas station toilet. And you lay your face on it every single night.

The Shocking Reality Behind Your Pillowcase

A recent study revealed that after just one week without washing, a pillowcase can collect over three million bacteria per square inch. That’s more than you’d find on the average toilet seat. Let that sink in—three million microscopic invaders building up on the very thing you nuzzle up to at bedtime.

This invisible buildup can include everything from dead skin and sweat to mold, saliva, and even dust mites. And if you’ve been waking up with mystery breakouts, itchy skin, or allergy symptoms, your pillow might be the reason why.

17,000 Times Dirtier Than a Toilet Seat

You read that right. The study found pillowcases can be up to 17,000 times dirtier than a toilet seat. So while you're enjoying Chicago deep-dish or hiking in Starved Rock, bacteria might be thriving on your bedding back home.

How Often Should Illinoisans Be Washing Their Pillowcases?

Experts recommend washing your pillowcase at least twice a week—especially if you sweat while sleeping (hello, Midwest humidity), have sensitive skin, or share your bed with pets. Use hot water and mild detergent to eliminate germs and keep your pillow fresh.

Better Sleep Starts With a Clean Bed

Clean bedding doesn’t just smell better—it helps improve your sleep and skin health. Whether you live in Springfield, Peoria, or downtown Chicago, your bedroom should be a clean, peaceful retreat, not a bacterial hotspot.

So go ahead, strip the bed and throw those pillowcases in the wash. Your face—and your immune system—will thank you.
