Capsizing at sea can become a dire situation very quickly if the necessary cold water gear is not available to those in trouble. Thousands of people die annually from hypothermia brought on by cold water. Hypothermia is defined as a core body temperature of 35°C and below.
Symptoms of Hypothermia
Mild hypothermia is indicated by mental confusion and shivering, moderate hypothermia occurs when the shivering stops and confusion increases. Severe hypothermia can often cause complete delusions with increased risk of heart failure and the shutting down of organs.
