Remember that in Europe and the UK people don't have access to the type of dryers that Americans use that actually ... get clothes completely dry in a reasonable time period. In fact those sorts of vented dryers that make Americans think that dryers are supposed to actually get clothes dry are being made illegal in the EU:

So we hang clothes outside in good weather, and otherwise use heat-pump washer-dryers to get things partially dry, and then hang them around the house. So you will typically need to sleep while sheets are drying.
