“Professor Popsicle” (Dr. Giesbrecht) takes eight volunteers and dunks them in 45 degree F water to show you what really happens in sudden cold water immersion and what happens as a person gets hypothermia. Graphic video shows why you should wear your lifejacket.
Professor Popsicle has developed the 1-10-1 guide to help understand what happens to people in cold water:
Cold Shock (1 minute to get your breathing under control).
Cold Incapacitation (10 minutes to self rescue yourself before your hands, arms, legs stop working).
Hypothermia (About 1 hour before you become unconscious) IMPORTANT NOTE – If you are not wearing a lifejacket only the first 10 minutes are relevant. Treatment of hypothermia is also covered. There are several must see videos on their site for everyone that is around cold water.
