I only really have boring answers, but for me, nature does do it. And the data back it up. I try (and do not always succeed) at getting a stroll out in the nearest patch of green for at least 30 minutes in a day, and find that helps enormously. I do go with a local walking group about once a month, who I absolutely adore going with, because the pressure to actually be social and actively converse is approximately zero, so every little conversation and chuckle is a voluntary, fun win.

Books I find to sometimes be very relaxing escapism, Portrait of Dorian Grey especially completely removed me from reality for an hour a day.

Some days, I absolutely love having half a day to dedicate to baking - I often just love the process of feeling free and wholesomely productive more than the actual end results, so I either make weird breads or try to do something time-consuming and complex so I don't have tons of sugar to consume afterwards. Bonus points for hummus making, putting together a stew of as many vegetables and beans as I can imagine tasting good together, and letting it simmer all day, or other fun cooking.

I find a little benefit in meditation, some days. I only tend to manage ~10-15 minutes, but I've never regretted it, so I'd recommend giving it a try.

Yeah I dunno, mostly boring answers, but these are the truth. For me, the big things are changing your scenery, getting mentally involved in something complex but low-pressure, and (very low-pressure) socialising.
