I work from home and I go days without putting on clothes, I get my groceries delivered and don't leave the house for weeks. It's become sort of an adventure but I basically turned the house into a spa so I'm staying relaxed.
I make a point of getting out once a day to walk, shop or whatever. I still wear the same three day old clothes though. I probably look like a gold card wielding bum. But who cares. I get paid piles of money to do what I love (DevOps). +1 on the spa idea...
