On the other hand, if you leave the bed unmade, you expose the bacteria to fresh air and sunlight which dehydrates and destroys them. Scientists explain that during sleep, we sweat. In fact, the average amount of sweat we produce goes up to one liter of fluid per night. Sweat is the ideal surrounding for dust mites.
According to estimates, the number of dust mites residing in your bed is approximately 1.5 million. Their existence is not what causes a problem, but what they leave behind. More precisely, their excretions are responsible for dust allergies and asthma flare ups.
Carolyn Forte, director of the cleaning lab at the Good Housekeeping Institute, explains that leaving the bed unmade for some time after waking up in the morning is an excellent decision as the sheets have the time to dry from the nighttime tossing and turning.
Also, it’s important to wash the sheets every two weeks as well as the pillowcases.
