Lucked out, won the sauna league (we play doubles squash without a/c & no fans. 80% humidity & 85F heat = heat index 97F) again this year. I seem to be one the few, who isn’t concerned by the humidity during sport. It’s there, but doesn’t affect my game; though it may limit the hours I play. Second year, with same partner Winning!
Maybe I should pickup that hot yoga thing. A bunch of friends started doing that a few years ago, when it was the fad. (I always thought men do yoga was odd)
