Hypothermia is a condition that occurs when the body’s temperature falls below 95 degrees. Once this happens for a length of time, the result is a loss of physical dexterity and consciousness and finally death. In other instances, sudden immersion into frigid water can cause a reflexive gasp of air which may cause intake of freezing water and a greater chance of death from drowning.
Death from hypothermia can happen in as little as 15 minutes. And your body temperature will drop 25 times faster in water in comparison to air. Logically, children and smaller adults are at a greater risk as they will cool much faster than larger victims.
Flotation devices can help by helping to conserve energy (heat) so if you are able to hold onto your surfboard, do so. Don't think that swimming faster in the cold water will keep you safer. Don’t forget that hypothermia can happen in warm climates as well as the water even in the tropics is below 95 degrees and can bring down the core body temperature to that point after some time immersed in the water.
During prolonged hypothermia, the body will experience progressive stages:
1. Mild Hypothermia: You feel cold (difficulty speaking, slurring, heavy shivering)
2. Medium Hypothermia: You may lose muscle control or feel drowsy.
3. Severe Hypothermia: You may experience respiratory problems or cardiac arrest. This can lead to death.
Key Points :
Limit movement
Get out of the water if possible (even partially)
Do not massage the legs and arms
Do not drink alcohol to warm you
