How to Swim on a Hot Day

All dogs know how to swim because they dog paddle. So the best thing to do on a hot day is to get down by that water where it's super hot and get in and dog paddle. War was like 91 humidity with the humidity was up to a 99%. It's 90 degrees makes it feel like it's 130 because the water is around you. How come them when you get into water like a pool, which is 1000% water, right? Can we agree on that? That's what I don't understand.
