Warm water PT is what is recommended.

My local Easter Seals pool is heated to 98 degrees. It is indoor and actually feels a bit like a sauna... Many YMCA's have a 2nd pool that is warm for certain classes.

Even still, when my body temp is swinging crazily, it can feel too warm, or too cold.

I can generally tolerate swimming in HI, where the water is around 80 degrees.

What is the temperature of your pool?
