COLD WATER CAN HAVE CHILLING CONSEQUENCES
Boating is often enjoyed year-round. What is essential for our boating community to remember is that water temps below 77º F can start to affect your breathing. But when water temps are below 70º, things begin to get really dangerous.
DID YOU KNOW, YOUR BODY LOSES HEAT FASTER IN WATER THAN IN AIR?
Advocate with life-saving facts
The human body does not like cold water. If your body temperature drops by just 3.5 degrees, hypothermia begins.
Hypothermia is the result of your body’s inability to maintain its core temperature (98.6º F). In an attempt to protect your vital organs (brain, heart, lungs), your brain will start to shut down less necessary body parts and functions. See the chart below for survival times.
Understand the three stages of trauma in cold-water
Stage 1 – Cold Shock Response
In the first three minutes, your body goes into cold-shock response, when you’ll experience uncontrollable gasping, hyperventilation, vertigo, and panic.
Resist the urge to fight the water. Try to stay calm and raise your body to a floating position. While lying on your back, concentrate on steady, deep breathing.
Stage 2 – Cold Incapacitation
Within 30 minutes cold incapacitation occurs: Your arms and legs start cooling down, which impairs their function regardless of your swimming ability.
Prioritize your most essential functions first, like deploying emergency communications and distress signal devices.
Stage 3 – Immersion Hypothermia
Immersion hypothermia begins after 30 minutes. Cooling of your body’s core temperature eventually results in the loss of functioning consciousness.
Your rate of survival for all stages increases when wearing a life jacket. However, in Stage 3, your life jacket is likely your best tool for survival.
How to H.E.L.P and rescue
If the unexpected happens and it’s “person” overboard into cold water, it’s important they minimize activity until their breathing is under control. Yes, easier said than done, but their life depends on it. If you are in a position to assist others, it’s important to rescue yourself first, then locate and assist others and then deploy emergency communication and distress signaling devices. It is important to both, alert authorities that there is an issue, and launch distress signals, this will aid search and rescuers to find you.
If getting out of the water and into or onto your boat is not an option, you must quickly minimize heat loss. First tighten your life jacket, collar, cuffs, hood, shoes, and anything, and everything to help reduce water flow around your skin.
Assume the HELP position (Heat Escape Lessening Posture) where you bring your knees to your chest and your arms grasp your lower legs. It protects your body’s three major areas of heat loss, which are your head/neck, groin, and armpits.
Upon rescue, medical treatment is a must. Warming and “feeling good to go home” is too often followed by death from capillary failure. Get medical attention immediately!
