In colder weather, it's important to remember
that you must be careful of the dangers of hypothermia when boating
or riding a personal watercraft.
Spring and fall: Prime times to become a
victim of hypothermia
There are days the air may feel warm and
the thrill of being out on the water is greater than the fear of
how cold the water actually is and what could happen if you were
to fall overboard or capsize.
Off-season (or early- or late-season) ventures
on the water pose special circumstances.
There are fewer boaters on the water so the likelihood of a prompt
rescue is greatly reduced. Also, people don't anticipate falling
into the cold water and therefore don't prepare for it. But there
are things you can do to prevent the risks associated with hypothermia
things
that could save your life.
Hypothermia facts
Hypothermia is a condition that exists when body temperature drops
below 95 degrees. This can be caused by water or air exposure. And
the body can cool down 25 times faster in cold water than air. Factors
such as water temperature, body fat, body size and movement all
play a part in how quickly the body's temperature drops.
PFDs for protection
The number one thing you can do to protect yourself against the
results of hypothermia is to wear a life jacket. A Personal Flotation
Device (PFD) can help in many ways. A PFD can prevent you from having
to exert energy and body heat to try to stay afloat. It can help
keep your head above water and reduce the chances of you inhaling
water due to the immersion gasping reflex caused by cold water.
And it can also help hold in body heat.
When in cold water
When boating in cold water, it is a good idea to wear a wet suit
or some type of neoprene undergarment to hold in body heat. Even
with a wet suit on, hands can get cold quickly, so gloves can be
an important layer. As most of your body heat is lost through your
head, it's important to try to keep your head as dry as possible.
A hat is a good idea.
Conserving heat: Goal Number One
Conservation of heat is the number one objective for a person who
has fallen into cold water. You should try to pull yourself as far
out of the water as possible to reduce heat loss. If you can climb
on top of an upturned boat or anything that floats, it can increase
your survival time.
Assume the H.E.L.P.
If you can't get out of the water, you should assume a Heat Escape
Lessening Posture (H.E.L.P.) - commonly referred to as the fetal
position, it helps you float effortlessly and helps protect those
areas most susceptible to heat loss. If there are others in the
water, huddle to share body heat and conserve the energy of the
group.
