I have a couple of go-to methods. When I have time and the weather is nice I visit my fav park, put up a hammock, smoke de ganja and just hang loose, watch birds, listen to music or meditate. Just walks out in nature are also great. I also like cooking and diying. Basically stuff that keeps my hands busy and my mind still. If I have money to spare I might get a massage. For things that trouble me and consume the energy that I would need for my day to day life I have found somatic shaking to be very beneficial.

But the most important part is to do all of these things consistently and not only as a last resort. Self care takes practice and it works for burnout prevention just as well as intervention.
