Help with pool temperature

This is not intended to be another rant thread on the topic. There are more than enough of those here already. Our pool director just jacked the pool temp up. He said he is responding to complaints from the aquarobic folks and because the local schools are bringing kids in for lessons. He said it was 82 today, but I don't believe it. It's usually between 80 - 82, and it was a whole bunch warmer today. We couldn't really work out at all, and ended up just going back and forth. I ditched my cap for the first time in maybe 6 months, but it didn't help. We all got overheated anyway. Can anyone point me to a study about the hazards of a bunch of fat old dudes (and, of course, our much svelter dudettes) trying to go too hard in tepid spa water? Or any study relating to the dangers of overheating while exercising? It occurs to me that a pool that is slightly too cold for comfort for some may be an annoyance, but a pool that is too hot may be a danger. Most of the stuff I found after a quick search relates to pregnancy. I'm not even a little pregnant. As far as I know.
