1.
Spa or hot tub water temperature should never
exceed 104°F (40°C). One hundred degrees
Fahrenheit (100°F [38°C]) is considered safe for
a healthy adult. Special caution is recommended
for young children.
2.
The drinking of alcoholic beverages before or
during spa or hot tub use can cause drowsiness
which could lead to unconsciousness, and subse-
quently result in drowning.
3.
Pregnant women take note!
Soaking in water
above 102°F (38.5°C) can cause fetal damage
during the
fi
rst three months of pregnancy (which
could result in the birth of a brain-damaged or
deformed child). If pregnant women are going
to use a spa or hot tub, they should make sure
the water temperature is below 100°F (38°C)
maximum.
4.
The water temperature should always be checked
with an accurate thermometer before entering a
spa or hot tub. Temperature controls may vary by
as much as 1F° (1C°).
5.
Persons with a medical history of heart disease,
diabetes, circulatory or blood pressure problems
should consult their physician before using a hot
tub or spa.
6.
Persons taking any medication which induces
drowsiness (e.g., tranquilizers, antihistamines, or
anticoagulants) should not use spas or hot tubs.
7.
Prolonged immersion in hot water can induce
hyperthermia.
Hyperthermia occurs when the internal body
temperature reaches a level several degrees above the
normal body temperature of 98.6°F (37°C). Symptoms
include dizziness, fainting, drowsiness, lethargy, and
an increase in the internal body temperature. The
effects of hyperthermia include:
