A. The water in a spa should never exceed 40°C (104°F). Water
temperature between 38°C (100°F) and 40°C (104°F) is
considered safe and comfortable for a healthy adult. Lower
water temperatures are recommended for young children and
when spa use exceeds 10 minutes.
B. 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
temperature to 38°C (100°F).
C. Before entering a spa, the user should measure the water
temperature with an accurate thermometer since the tolerance
of water temperature regulating device varies.
D. The use of alcohol, drugs, or medication before or during spa
use may lead to unconsciousness with the possibility of
drowning.
E. Obese persons and persons with a history of heart disease,
low or high blood pressure, circulatory system problems, or
diabetes should consult a physician before using a spa.
F. Persons using medication should consult a physician before
using a spa since some medication may induce drowsiness
while other medication may affect heart rate, blood pressure,
and circulation.
G. Avoid putting the head under water at all times.
H. Avoid swallowing spa water.
• TO REDUCE THE RISK OF INJURY: Never pour water with a
temperature higher than 40°C (104°F) into the spa pool directly.
• The use of alcohol, drugs, or medication can greatly increase the
risk of fatal hyperthermia. Hyperthermia occurs when the internal
temperature of the body reaches a level that is several degrees
above the normal body temperature of 37°C (98.6°F). The
symptoms of hyperthermia include an increase in the internal
temperature of the body, dizziness, lethargy, drowsiness, and
fainting. The effects of hyperthermia include failure to perceive
heat; failure to recognize the need to exit spa or hot tub;
unawareness of impending hazard; fetal damage in pregnant
women; physical inability to exit the spa or hot tub; and
unconsciousness resulting in the danger of drowning.
• Electric installations should follow national wiring rules, consult a
qualified electrician with any questions.
