Might not be a universal answer - but game!

There's just something therapeutic about playing solo RPG games like Diablo, God of War, Assassins Creed, etc. Anything immersive lets me forget about all the stress.

Good thing is if you want to mix stress relieving (i.e., gaming) with productivity, you can now. I've been playing crypto-earning games like Axie, Thetan, and an upcoming one called Wizardia (ngl, it looks pretty cool).

Honestly, anything that takes your mind off the work and stress (as long as its not anything like drugs lol) should be good enough.
