My husband, an introvert with autism, wanted to chime in and say that he needs some alone time with his special interest (either baseball cards or geography/maps) to fully recharge.

Another thing that helps me is taking a shower. Simple yet effective.

Playing games with a few close friends, that or programming

Rimworld, honestly. The game is engaging enough to catch my attention in short bursts but slow enough that it isn't overwhelming when winding down.

For me nature. I love being surrounded by nature. Sometimes I just chill on a bench with a coffe or listen to a podcast in a park, while watching the clouds pass by or watching people walk their dogs.

It sounds boring, but really helps to focus my thoughts again.

Yes!

Ohh depends on my mood.

Low effort: Futurama on shuffle.

Energy but I'm over people: single player RPG

Insomniac: write some code.

Unfortunately most of the time I just end up doing head of household chores until I pass out from the misery.
