You wash your sheets, fluff your pillows and maybe even spritz some linen spray – but when was the last time you thought about what’s lurking inside your mattress? Spoiler alert: it’s not just organic cotton and good vibes. From dust mites to bed bugs, your mattress might be hosting more guests than you’d like. 

The average person spends about a third of their life sleeping, which means your mattress gets plenty of use. But what's happening beneath those crisp, clean sheets while you’re dreaming In this blog, we'll pull back the covers on what's living in your mattress. And, fair warning, it may make you want to run out and buy a mattress protector. (Don't worry, we've got you covered. Literally!)

Several things that can make your mattress dirty. Mattresses can host an entire ecosystem of uninvited guests.

These microscopic creatures are the most common unwanted mattress inhabitants. While they’re too small to see with the naked eye, they can exist in mind-boggling numbers.

The average mattress can contain anywhere from 100,000 to 10 million dust mites. They feed primarily on the dead skin cells you shed while sleeping. And while they aren’t harmful themselves, their waste products are a major allergen. 

Unlike dust mites, bedbugs are visible to the naked eye – though they're experts at hiding. These apple seed-sized pests feed on blood and are notorious for causing itchy welts.

Contrary to popular belief, bedbugs aren't attracted to dirt – they're drawn to the carbon dioxide you exhale and your body heat. Signs of bedbugs include rusty-colored spots on your mattress (their excrement), shed skins and a musty odor. Note: If you suspect bedbugs, you'll want to take immediate action. These persistent pests are notoriously difficult to eliminate.

Each night, the average person releases about half a pint of sweat into their mattress and bedding (who knew!). Over time, this moisture combines with the natural oils from your skin to create those distinctive yellowish stains you might notice when changing your sheets. This can create an ideal environment for bacteria growth.

As fluids break down, they can also produce unpleasant odors that even fresh sheets can't mask. Sweat moisture can penetrate your mattress, creating a damp environment that's perfect for bacteria and fungi to thrive. Memory foam mattresses are especially excellent at trapping heat and moisture. 

Humans shed approximately 500 million skin cells every day. Some of this finds its way into your mattress. Skin cells accumulate over time, which can attract dust mites. The more skin cells in your mattress, the more dust mites will multiply.

And let's not forget about hair. The average person loses between 50-100 hairs per day, many of which end up on your mattress. Hair can trap oils and dirt. This is why cleaning your mattress is very important! 

Beyond dust mites, your mattress can hold allergens that may affect your health without you realizing it.

Pet parents – unfortunately, pet dander is a common culprit! This is especially true if your furry friends join you for bedtime. But even if your pets never set paw on your bed, their dander can travel through the air and settle into your mattress.

The moisture from sweat and humidity creates perfect conditions for mold and mildew growth in your mattress. These fungi cause unpleasant odors and can trigger allergic reactions. Without proper ventilation, mold colonies might develop inside your mattress.

Before you toss your mattress to the curb in horror, take a deep breath. You can keep your mattress cleaner without turning into a cleaning fanatic!

Washing your bedding is a great start. Sheets, pillowcases and duvet covers should be washed in hot water (at least 130°F) to kill dust mites and remove allergens.

Cleaning your room and vacuuming regularly helps too. Pay attention to seams and crevices where dust and skin cells accumulate. And if you see stains, blot (don't rub!) immediately using a clean cloth. For older stains, a mixture of baking soda, salt and water can work wonders.

Sometimes, you just need to air out your mattress. Leave it uncovered for a few hours to allow moisture to evaporate. If possible, open windows to increase air circulation. 

Every three to six months, rotate your mattress to ensure even wear and prevent body impressions that can collect moisture and debris. And maintain humidity levels between 30-50% to discourage dust mites and mold growth (a dehumidifier can help!).
