Not the toilet, this is the place with the most bacteria in the house, experts advise regular cleaning to avoid ‘inviting’ more diseases into the body | March 16, 2025

Experts say this is where your sleep and health can be at risk.

According to one study, on average, single men change their sheets only once every four months, married couples change their sheets monthly, and single women fare a little better, changing and cleaning their sheets an average of once every two weeks.

Over time, bed sheets, blankets and pillows become breeding grounds for dust mites and bacteria, and on top of that, infections can be transmitted through dirty bed sheets.

So is your bed a breeding ground for germs? Some experts have created a 10-question calculator that asks you questions about topics like how long you keep your sheets on, what you wear in bed, and your cleaning habits.

Then use the answers to assess whether the bed is potentially hazardous to your health and recommend the appropriate time to change the sheets.

5 health risks if you don’t change your bed sheets regularly

According to experts, in addition to maintaining proper hygiene by cleaning your sheets, it is important to change other items such as blankets and pillows. Experts say these play a key role in your sleep and overall health.

Experts have listed 5 health risks you may encounter if you do not regularly clean and change your bed sheets, blankets, and pillows:

Increased risk of colds and allergies over time.

Over time, bedding becomes a breeding ground for dust mites, which are too small to see but are numerous.

Hundreds of dust mites can thrive in just one gram of dust, and they survive for up to 90 days, reproducing and multiplying.

Dust mites love moisture, so be sure to clean your bedding regularly.

If you are sensitive to dust mites or have allergic rhinitis, you may have difficulty sleeping, wake up more at night, and snore.
