I agree - I think sleep is the only universal here. I find different things may help at different times, too, or become more important to counter different external stressors and anxieties. I've never found exercise to be a particularly important part of my mental health, but in lockdown I've become utterly dependent on it. It provides routine, structure, control and a sense of progress - all of which I was getting more of in other places before but which I'm now lacking without the exercise.
