How Do Musicians Balance Health With Busy Touring Schedules?

I was thinking about how much a band's image has always been part of metal culture. From stage outfits and hair styles to overall confidence during performances, appearance can sometimes become part of a musician's identity.
Do any musicians here have a regular self-care routine before tours or shows? I know some people focus on fitness, skincare, or other wellness habits to feel more confident on stage. A friend of mine recently mentioned looking into a medspa san Ramon option for personal care, which got me wondering how many metal fans or performers actually pay attention to that side of things.
Is appearance important in building a stage presence, or should the music always be the only thing that matters?
