how do pro athletes 'kill time' before a match if it's in the evening?

if an athlete has a match/event in the evening, how do they kill time before that?

must be hard to keep your mind off it and not 'let loose' but also not go crazy overthinking it before

i know the hour or two before the match/event would be warming up/getting in the zone etc - but before that. also you don't want to be hitting a workout or kill time that way

video games?
Overthinking, overanalysing separates the body from the mind
