Ah, yes, this again. Basically, the argument (which was challenged even within that article:”Professor Andrew Wardlaw, of the British Society for Allergy and Clinical Immunology, agreed.He said: ‘Mites are very important in asthma and allergy and it would be good if ways were found to modifiy the home so that mite concentrations were reduced. It is true that mites need humid conditions to thrive and cannot survive in very dry (desert like) conditions.However, most homes in the UK are sufficiently humid for the mites to do well and I find it hard to believe that simply not making your bed would have any impact on the overall humidity.’”) is that making your bed causes a humid environment in which dust mites flourish.
Wash your sheets. Regularly. Weekly, at least.
Vacuum your mattress. I do this monthly. It takes about four minutes.
If you’re truly concerned about mites, then neatly fold your top sheet and blankets/comforter/duvet down at the foot of the bed, straighten your pillows, and consider your bed made.
