The : The thermostat you are running it at is appropriate. Too warm can cause patients to feel light--headed or pass out. Warm water can grow bacteria, but typical cleaning/chlorine that you perform for hot tub maintenance will take care of that.

Common sense : Probably not the right forum, but you are presenting a question that will need goals prioritized and clarified. The technical book or the manufacturer should give you a range of safe temperatures, everything else remains a matter of beliefs and choice for you. Would suggest in the recommended range the temperature that works best for you.
