Use the temperature settings of the hot tub to dial down the temperature. The temperature of the hot tub should not be more than 100 degrees F (9)
  6. If you start feeling any kind of discomfort, dizziness, lightheadedness, or pain – get out of the hot tub immediately and get your body temperature to a lower degree.
