2. Since excessive water temperatures have a high potential for causing fetal damage during the early months of pregnancy, pregnant or possibly pregnant women should limit spa water temperatures to 100° and check with their doctor before use.

3. Before entering a spa, the user should measure the water temperature with an accurate thermometer since the tolerance of water temperature regulating devices varies.

4. The use of alcohol, dugs or medication before or during spa use may lead to unconsciousness with the possibility of drowning.

5. Persons suffering from obesity or with medical history of heart disease, low or high blood pressure, circulatory system problems, or diabetes should consult a physician before using a spa.

6. Persons using medication should consult a physician before using a spa since some medications may induce drowsiness while other medication may affect heart rate, blood pressure, and circulation.

7. Prolonged immersion in hot water may induce hyperthermia. Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above the normal body temperature of 98.6° F. Symptoms of hyperthermia include dizziness, lethargy, drowsiness and fainting. Effects of hyperthermia include failure to perceive heat, failure to recognize the need to exit the spa, unawareness of impending hazard, fetal damage in pregnant women, physical inability to exit the spa, and unconsciousness resulting in the danger of drowning.
