What temperature do you get hypothermia in water?
It develops much more quickly than standard hypothermia because water conducts heat away from the body 25 times faster than air. Typically people in temperate climates don't consider themselves at risk from hypothermia in the water, but hypothermia can occur in any water temperature below 70°F.
How long does it take to get hypothermia in water?
At a water temperature of 32.5 degrees, death may occur in under 15 - 45 minutes. At a water temperature of 32.5 to 40 degrees, death may occur in 30 - 90 minutes. At a water temperature of 40 to 50 degrees, death may occur in 1 - 3 hours. At a water temperature of 50 - 60 degrees, death may occur in 1 - 6 hours.
Symptoms of hypothermia
The symptoms of hypothermia differ depending on its severity. Mild or moderate hypothermia can easily become more severe if left untreated, so it’s important to keep monitoring the victim for any changes in symptoms that may occur.
Recommended treatments for hypothermia
When treating someone for hypothermia, it’s important to warm them up in a way that doesn’t shock their body or increase the circulation of cold blood towards their vital organs, which can trigger cardiac arrest. The procedure to follow depends on the severity of the hypothermia.
Cold water survival
There are a few things you can do to give yourself a better chance of survival if you find yourself in cold water. Your best option is to get yourself out of the water as fast as possible. If your boat is equipped with a reboarding device such as a ladder, you’ll have a better chance of getting yourself out of the water before the cold sets in.
Boat safely with Drive a Boat Canada
Hypothermia is a very real and present threat on the water. The odds of survival increase significantly if it is recognized and treated in time, which is why it’s so important for boaters to know how to handle the situation.

What is Hypothermia?
Hypothermia is a medical condition that occurs when extended exposure to cold weather causes the body temperature to dangerously drop. According to the CDC, “While hypothermia is most likely at very cold temperatures, it can occur even at cool temperatures (above 40°F) if a person becomes chilled from rain, sweat, or submersion in cold water.”
Preventing Hypothermia
Preventing hypothermia is as simple as making sure you and your passengers stay warm while boating. Make sure everyone is bundled up in warm, weather-resistant clothing. Make passengers don’t spend too much time above-deck in the cold. If you don’t have a cabin with heating, only plan for short trips in cold weather.
Symptoms of Hypothermia
When out on the water in chilly temperatures, and especially if someone in your boat falls overboard, be on the lookout for symptoms of hypothermia. These include:
The 1-10-1 Rule
If you or a passenger falls off the boat and is submerged in freezing waters, following the 1-10-1 rule can save a life.
How To Treat Hypothermia
When someone shows symptoms of hypothermia, whether from falling overboard or simply from prolonged exposure to cold temperatures above-deck, it’s essential to immediately begin treatment and head for land to seek professional medical attention. Here are the steps for treating hypothermia while still on your boat:
How to tell if a victim is hypothermic?
The victim shivering , but coherent, indicates mild hypothermia symptoms. Move victim to place of warmth. Remove wet clothes; give warm, sweet drinks; NO alcohol or caffeine. Keep victim warm for several hours.
How to stay safe on a cold weather boat?
Following a few simple rules will help keep your safe, or at least increase your chances of returning home. Wear warm clothing. Wear a PFD at all times. Every year we read and hear about the 'experienced boaters' that die in cold weather boating accidents. Nearly every one of those missing mariners was not wearing a flotation device. File a float plan. Never go out alone. Check the weather before leaving home. While on the boat keep an eye on the weather and know when to quit and head for home. Even in cold weather, leaving the dock is optional, but returning is mandatory.
How does hypothermia affect the body?
Remember that the symptoms of hypothermia include shivering as the body loses heat and body temperature drops, uncontrolled rapid breathing follows the initial gasping response and may cause a loss of consciousness, muscle rigidity and loss of voluntary motor function which results in physical helplessness. A hypothermia victim starts to shiver as core body temperature falls from 97?F. down to about 90?F. A person at risk of hypothermia must try to control breathing rate to avoid hyperventilation leading to unconsciousness following the immediate involuntary gasping response to the initial immersion into cold water. Uncontrolled or rapid breathing will speed up the chilling process. When the body's core temperature falls to 93?F. physical ability is severely diminished and mental capacity begins to deteriorate rapidly. A victim usually falls into an unconscious state when body temperature falls to 86?F. If the victim doesn't drown first, hypothermia will finish him off when the body temperature falls to or near 80?F. Survival figures show that an adult dressed in average clothing may remain conscious for one hour in water at 40?F, and perhaps as long as 2 - 3 hours in 50?F water. Remember, any movement in water accelerates body heat loss. The recent film, Titanic, graphically portrayed the fatal effects of lowered body temperature on persons in the water.
Why do people avoid cold water?
The main objective is to avoid entering the water because immersion in cold water rapidly incapacitates and may quickly kill boaters who are not wearing protective clothing. Surfers, sailboarders, kayakers and other folks in similar sports wear wetsuits or drysuits to protect themselves from the cold water. Smart off-season boaters, including sailors, fishermen, hunters, and others take similar precautions to improve their safety while on the water including never going out alone.
What happens if you fall into cold water?
During cold weather boating all persons on board should wear life jackets. Cold shock from falling into icy water can trigger an involuntary gasping reflex that will cause you to inhale water through your mouth. Without a life jacket a person can drown without ever coming back to the surface. Wearing your life jacket will increase the likelihood of survival if you should accidentally fall into the cold winter water. Cold shock may also result in cardiac arrest. When the head and chest are exposed to cold water, the result is often a very sudden increase in heart rate and blood pressure. Cold water immersion can also result in immediate loss of consciousness but, depending on the type of life jacket worn an unconscious victim can survive without drowning.
How does cold water affect your body?
To properly prepare, you have to first understand what happens to your body in cold water. Water removes heat from a body 25 times faster than cold air and most of the body heat is lost through the head. Swimming, thrashing about, and other physical activity increases the heat loss through the limbs and extremities. If you become a person in the water (PIW) you will sharply reduce your survival time though physical activity. Strong swimmers wearing a PFD have died before they covered 100 yards in cold water. Did you know that in water with a temperature of less than 40? F., a strong man can expire before he can swim 100 feet? Two factors come into play against you while you are immersed in cold water; they are cold shock and hypothermia.
How to revive a dead person after being removed from the water?
Assume victim can be revived. Apply dry clothing or covers like above. Look for signs of pulse or breathing during first two minutes. If pulse or breathing is found, even in trace amounts DO NOT start CPR. In this state, CPR can cause cardiac arrest. If you can't find a pulse or sign of breathing, CPR should be started only by a trained and qualified crewmember. Rush victim to nearest medical facility by best means available.
How to raise body temperature?
Depending on the severity of hypothermia, emergency medical care for hypothermia may include one of the following interventions to raise the body temperature: 1 Passive rewarming. For someone with mild hypothermia, it is enough to cover them with heated blankets and offer warm fluids to drink. 2 Blood rewarming. Blood may be drawn, warmed and recirculated in the body. A common method of warming blood is the use of a hemodialysis machine, which is normally used to filter blood in people with poor kidney function. Heart bypass machines also may need to be used. 3 Warm intravenous fluids. A warmed intravenous solution of salt water may be put into a vein to help warm the blood. 4 Airway rewarming. The use of humidified oxygen administered with a mask or nasal tube can warm the airways and help raise the temperature of the body. 5 Irrigation. A warm saltwater solution may be used to warm certain areas of the body, such as the area around the lungs (pleura) or the abdominal cavity (peritoneal cavity). The warm liquid is introduced into the affected area with catheters.
How to warm blood?
Heart bypass machines also may need to be used. Warm intravenous fluids. A warmed intravenous solution of salt water may be put into a vein to help warm the blood.
How to get rid of a swollen groin?
Use warm, dry compresses. Use a first-aid warm compress (a plastic fluid-filled bag that warms up when squeezed) or a makeshift compress of warm water in a plastic bottle or a dryer-warmed towel. Apply a compress only to the neck, chest wall or groin. Don't apply a warm compress to the arms or legs.
What is the best way to warm up the body?

What to do for hypothermia?
Passive rewarming. For someone with mild hypothermia, it is enough to cover them with heated blankets and offer warm fluids to drink.
What causes the body temperature to drop?
Heat applied to the arms and legs forces cold blood back toward the heart, lungs and brain, causing the core body temperature to drop. This can be fatal. Don't apply direct heat. Don't use hot water, a heating pad or a heating lamp to warm the person.
