Not the toilet—this area has the most bacteria in the house. Experts recommend regular cleaning to prevent inviting diseases into the body.

Experts warn that your sleep and health could be at risk if you neglect your bedding. A study found that single men change their sheets only once every four months, while married couples do so monthly, and single women change theirs about every two weeks.

Over time, sheets, blankets, and pillows can become breeding grounds for dust mites and bacteria, increasing the risk of infections. To assess whether your bed is a health hazard, some experts have developed a 10-question calculator that evaluates your cleaning habits, how often you change your sheets, and what you wear to bed.

5 Health Risks of Not Changing Bed Sheets Regularly

Increased Risk of Colds and Allergies: Bedding accumulates dust mites, which thrive in moisture and can affect sleep quality.

Spread of Infection: A 2017 study showed that dirty sheets can transmit infections. Wash your bedding promptly when you’re unwell, especially if sharing a bed. A 2022 study found that pillowcases have 39 times more bacteria than pet bowls, and sheets have 5.4 times more than toothbrush holders.

Neck Pain: Pillows and mattresses lose shape over time, causing discomfort and disrupting sleep, which can lead to neck and back pain.

Skin Issues: Skin oils, sweat, and dead skin cells accumulate on bedding, potentially causing clogged pores and breakouts. Regularly changing sheets can help maintain healthier skin.

Hygiene Issues: Regular washing of duvet covers, pillowcases, and sheets is essential. Experts recommend washing these items at least every two weeks in hot water. Pillows should be washed every three months to eliminate bacteria. Blankets need washing at least twice a year, or more frequently if they get dirty or if you sweat a lot.

Overall, maintaining clean bedding is crucial for your health and well-being.
