How Hypothermia Affects Most Adults - Mustang Survival MD6254 Guide D'utilisation

HYPOTHERMIA
Prolonged exposure to cold water causes a condition known as
hypothermia – a substantial loss of body heat which leads to
exhaustion and unconsciousness. Most drowning victims first
suffer from hypothermia. The following chart shows the effects of
hypothermia:

HOW HYPOTHERMIA AFFECTS MOST ADULTS

Water Temperature
˚C (˚F)
0.3 (32.5)
0.3–4 (32.5–40)
4–10 (40–50)
10–16 (50–60)
16–21 (60–70)
21–27 (70–80)
over 27 (over 80)
PFDs can increase survival time because they allow you to float
without using energy treading water and because of their insulating
properties. Naturally, the warmer the water, the less insulation you
will require. When operating in cold waters [below 15.6°C (60°F)] you
should consider using a coat or jacket style PFD or a Type V Thermal
Protective PFD as they cover more of the body than the vest or belt
style PFDs.
