All depends how dirty the sleeper is doesn’t it? Pull duvet back and fling windows open every morning -the time it takes to visit the bathroom and get the kettle on can be enough.
Sometimes changing pillowcases is good enough.
.."?..And keeping pets of the bed, …not eating a flake in bed.
Sound advice!
I sleep alone, no pets (my cat sleeps with my daughter, not me!)
I used to wash the bedding weekly but nowadays I do it fortnightly in summer and every 3 weeks in the winter months.
No tumbledryer.
