COLD WATER CAN TAKE YOUR LIFE AWAY
Boating isn’t only a warm-water good time. It’s year-round serious fun (as is our mission). And sometimes that fun happens to be in “cold water.” We’re not talking about Lake Michigan in January cold water. We’re talking about water below 77º F, which is the temperature that starts to affect your breathing. And when water is below 70º, things start to get real dangerous.
YOUR BODY LOSES HEAT FASTER IN WATER THAN IN AIR.
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.
You will experience three stages of trauma in a cold-water event:
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.
If the unexpected happens and you get thrown overboard into cold water, it’s important that you minimize activity until your breathing is under control. Yes, easier said then done, but your life depends on it. Also, it’s important to first rescue yourself, locate and assist others and then deploy emergency communication and distress signaling devices. It is important you carry both, to alert authorities there is an issue and to 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, 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 with death from capillary failure. Get medical attention immediately.
