sauna suits

has anyone used sauna suits for recovery?
ive been mainly boxers use them, but was thinking maybe they can help sprinters, either for recovery, or in cold weather to help warm up better?

any thoughts?

I can’t see how a sauna suit could be useful for recovery or warmup.

I think the only thing they’re good for is making you sweat profusely (and feel like crap afterward).

wouldnt the sweating help remove toxins?
