I agree that deliberately breaking the work-from-home routine is helpful for mental and physical health. Not very sure that people need a bath every day though (there were studies showing that some soaps and shampoos are really bad for the skin so shouldn't be applied daily).

IMO working from home can even further destroy your work-life balance -- but only if you let it, which is sadly easy in these conditions. So I agree with you there, we have to get out of our way -- literally and figuratively -- to compensate for some negative WFH traits.
