In fact, the British researcher Stephen Pretlove, Kingston University in London stated: If you make your bed every morning, you will create an excellent habitat for house-dust-mites. Something as simple as leaving a bed unmade during the day can remove moisture from the sheets and mattress so the mites will dehydrate and eventually die. Thus, he emphasises the importance of heat and moisture for mites to survive.
However, it was pointed out that blankets which are spread over the bed and stuck between the mattress and the bed frame are frequently used in the UK. If a bed cover is used as well, actually warm, damp conditions will be created ideal for the mites to thrive.
The advice of the British researcher cannot exactly be assigned to down-and feather-filled- duvets that are most common in Germany. It is advised that you fluff up your down-and-feather-filled duvets daily to remove the moisture that developed during the night. The longer the duvets are aired, the better dry and cool conditions are created less likely in mites to thrive.
