Experts' Experts: How often should you change your sheets?

From Bustle:

Autumn is fast approaching, which means your cozy duvet will be making a triumphant return.

While there's nothing like curling up in your bed on crisp fall nights, it also brings up the age-old question of how often should you change your bed sheets.

It depends on your sleep regimen, from how much you move in your sleep to your level of clothing when you hop between the sheets.

You also need to consider whether you're sleeping by yourself or sharing the bed with a person, pet, or both.

Dead skin cells, body oils, drool, and dust mites are just some of the detritus that accumulate in your sheets over time.

If you have acne, it could be something to do with your bed sheets.

Dermatologist Whitney Bowe said not changing your sheets frequently "can disrupt your skin's ecosystem" — otherwise known as its microbiome — due to bacteria accumulating on your pillowcase.

So, what's the optimum amount of time to wait before washing your sheets?

Most experts say to do so on at least a weekly basis.

Good Housekeeping suggests that "at least once every two weeks" is fine, but also notes that if you tend to sweat a lot in bed, "you should increase this to once weekly."

This also goes for people with allergies like hay fever as pollen can accumulate quickly in season.

Dust mites also factor into this, as they can provoke allergy symptoms like a runny nose, watery eyes, sneezing, and general discomfort that makes it hard to get a good night's sleep.

One study of pillows found from 4-16 different species of fungus in individual pillows, among 50 different species isolated.

The American Academy of Dermatology suggests changing your pillow cases two to three times a week.
