Can dirty pillows cause ear infections?

Yes, dirty pillows can contribute to ear infections or make existing ones worse by creating a breeding ground for bacteria, mold, and allergens, which can inflame the ear canal and disrupt normal Eustachian tube function, although direct causation is often anecdotal rather than definitively proven by science. Keeping pillowcases clean helps reduce bacteria and allergens near your ear, supporting ear health, especially for those prone to issues like swimmer's ear or recurring infections.

What happens if staph is left untreated?

If a staph infection (Staphylococcus aureus) is left untreated, it can progress from a minor skin issue to severe, life-threatening conditions like sepsis, toxic shock syndrome, endocarditis (heart infection), and widespread organ failure, potentially leading to death. Untreated staph can spread from the skin into the bloodstream (bacteremia) and then to bones, joints, or internal organs, causing serious complications. 

How do I tell if I have staph?
