Can a Dirty Pillow Cause an Ear Infection?

Jun 5th 2025

While there’s no direct scientific study proving that dirty pillows alone cause ear infections, mounting evidence and expert observations suggest a strong connection. Dermatologists and ENT specialists agree that unclean pillows can harbor harmful bacteria, fungi, and allergens all of which may irritate the skin and ears.

When was the last time you washed your pillow or pillowcase?

It’s a question many people don’t ask themselves often enough. Pillows play a significant role in sleep hygiene, yet they’re one of the most overlooked sources of bacteria in the home. Let’s take a closer look at how this happens, what symptoms to watch for, and how to keep your pillow clean and healthy.

Key Highlights

  • Dirty pillows can harbor bacteria, and allergens that irritate the skin and ears, increasing the risk of an ear infection.
  • Symptoms of an ear infection from a dirty pillow include itching, discharge, and in severe cases, fever and fatigue.
  • Wash pillowcases every 3–4 days and pillows every 3–6 months, using protectors to reduce allergens.

How Can a Dirty Pillow Cause an Ear Infection?

1

Bacteria and Germ Build-Up

Over time, pillows accumulate:

  • Sweat
  • Oil from hair and skin
  • Drool
  • Dust mites
  • Dead skin cells

This build-up creates a breeding ground for bacteria like Staphylococcus aureus or Pseudomonas, which can enter your ear canal especially if there’s a scratch, piercing, or skin irritation nearby.

2

Blocked Pores and Ear Pimples

Dirty pillowcases can clog pores around the ear, leading to:

  • Painful pimples near or inside the ear
  • Folliculitis (infected hair follicles)
  • Secondary infections from scratching or popping bumps
3

Worsening Existing Conditions

If you already suffer from eczema, dermatitis, or an outer ear infection (otitis externa), sleeping on a dirty pillow can worsen inflammation and delay healing.

4

Fungal Growth in Humid Conditions

Pillows, especially when exposed to sweat and drool, can remain damp and warm the ideal environment for fungal growth. This can lead to fungal ear infections caused by organisms like Candida or Aspergillus.

5

Cross-Contamination from Hair and Face Products

Hair sprays, gels, moisturizers, and makeup residue can transfer to your pillow and mix with oils and bacteria. This can irritate the skin around your ear and make it more vulnerable to inflammation or infection.

Signs You May Have an Ear Infection from a Dirty Pillow

Itching or Burning Sensation in the Ear

One of the earliest symptoms of an ear infection is persistent itching or a burning feeling inside or around the ear.

Swelling or Redness Around the Ear

If the skin near your ear appears red, puffy, or inflamed, this may indicate irritation or infection. Dirty pillows can harbor allergens and microbes that aggravate sensitive skin.

Pain or Pressure While Lying Down

Ear infections often cause pain or pressure, especially when lying on the affected side. If this discomfort intensifies while using your current pillow, consider replacing it with cleaner pillows that improve sleep quality and also offer better hygiene. Discover how CNH Pillows improve sleep quality and promote healthier rest.

Fluid or Pus Discharge from the Ear

Clear fluid or pus-like discharge may signal a progressing ear infection. If your pillow absorbs moisture from sweat or drool and isn’t washed regularly, it could be contributing to microbial growth near the ear canal.

Mild Fever or Fatigue in Severe Cases

In advanced infections, your body may react with symptoms like fatigue, body aches, or a mild fever.

Who’s at Higher Risk?

You may be more likely to develop ear infections from dirty pillows if you:

  • Sleep on one side for long periods
  • Use earbuds or headphones frequently in bed
  • Have sensitive or acne-prone skin
  • Rarely wash your pillowcases or clean your ears
  • Have ear piercings or cuts near the ear

How Often Should You Wash Pillows and Pillowcases?

  • Pillowcases: Wash every 3–4 days in hot water to kill bacteria and allergens.
  • Pillows: Wash every 3–6 months (check label for care instructions). Use hypoallergenic pillow protectors in between washes.

Tips to Prevent Ear Infections Caused by Dirty Pillows

  • Wash your pillowcases at least twice a week and pillows every 3–6 months to eliminate bacteria and allergens.
  • Avoid sleeping with wet hair, as moisture encourages bacterial and fungal growth on your pillow.
  • Disinfect earbuds, headphones, and phones regularly to prevent transferring germs to your pillow surface.
  • Gently clean the outer ear with a damp cloth and avoid inserting cotton swabs deep into the ear canal.
  • Use hypoallergenic, breathable pillows that improve sleep quality and reduce exposure to irritants.
  • Replace old pillows every 1–2 years since worn-out pillows harbor more bacteria and allergens.

When to See a Doctor

If symptoms don’t improve with basic hygiene changes or if you experience:

  • Severe ear pain
  • Hearing loss
  • Dizziness or nausea
  • Thick or yellowish discharge

Consult a healthcare provider immediately you may need antibiotics or further medical evaluation.

Conclusion

While there is no definitive scientific proof that dirty pillows directly cause ear infections, the accumulation of bacteria, fungi, and allergens on unwashed pillows can significantly increase the risk. Maintaining clean pillows and pillowcases plays a vital role in reducing irritation and preventing infections, especially for those with sensitive skin or existing ear conditions.
