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.
