When To Wash Your Bedsheets

Your bed is likely full of fungi, bacteria, animal dander, pollen, soil, lint, skin cells and bodily secretions. In other words your sheets are gross even if you think of yourself as a clean person. Humans naturally produce 26 gallons of sweat in bed every year making your bed an ideal place for fungi to grow.

A 2015 study found feather and synthetic pillows that are 1.5 to 20 years old can contain between 4 and 17 different species of fungus. Dust mites are also lurking in your bed and can cause reactions such as a stuffy nose or exacerbated allergies.

People who eat in bed have it the worst. Because food attracts bugs you can actually see. So, how often should you wash your sheets? about once a week to keep microbes to a minimum. but duvet covers only need to be cleaned about every 6 months.
