Cold Weather and Cold Water Paddling
Details
As winter arrives you will discover paddling in wintry conditions is rewarding when done safely. Fewer boats and people on the water means peaceful paddling. Migrating birds are plentiful and sea mammals haul out to warm up. The difference between enjoyed and “never do that again” is preparedness.
As the winter approaches prepare to spend more time on the water. Here are things you can do:
Dress for immersion means water temperature not air temperature.
Wear a properly fitted wetsuit, drysuit, or semi-dry suit.
Dress in synthetic wicking fabric layers to keep warm when wet.
Wear a wind- and water-resistant outer shell splash jacket.
Bring towels and extra clothes, a windbreaker, beanie in a dry bag.
Practice rescue in deep water in conditions you paddle in.
Southern Maine Sea kayaking Network posted a video from their October Meeting on Cold Weather Paddling with Moulton Avery, founder and director of the National Center for Cold Water Safety. Do yourself a favor and watch the video listed below. It may save your life.

COLD WATER IMMERSION RESPONSE
First, there is an involuntary, automatic gasp reflex, due to the rapid cooling. Drowning occurs if the head is under water at this stage as water is drawn into the lungs.
Hyperventilation is the next reflex. This deep rapid breathing causes a decrease in carbon dioxide, which makes you feel light-headed and short of breath, causing the heart to beat rapidly. Controlling breathing is a major step in avoiding hyperventilation.
Peripheral vasoconstriction occurs when the blood flows to the surface of the skin and limbs is reduced to allow the core to keep warmer blood.
Incapacitation due to cold happens between five to fifteen minutes of immersion. This is a critical time as movement is compromised in the hands, arms and legs.
It takes 15 to 20 minutes for a healthy adult to become hypothermic in water 55 F degree water.
