Anecdotally, I started lifting again a few weeks ago. Took a few years off due to Covid complications, but was previously exercising regularly.

Walked up to the bar stressed about all sorts of things, everything is expensive, car is making weird chafing noises when I make sharp turns, politics, this and that.

Did 3 sets of 5 deadlifts with a 60kg bar. Barely any weight on the bar since I didn't want to annihilate my joints. Regardless, as I finished the sets, all that stress was just gone, and it stayed away for days. I was calmer, clearer, more present.

I don't think I have fewer reasons to be stressed since getting the gym membership, but I sure am less stressed.

Deadlifts in particular, but really any full body lifts have always been a mental state degauss button for me. Doesn't matter how many problems you have before you walk up to that bar, you'll barely remember them when you're done.
