Hypothermia is a medical condition that occurs when the body loses heat faster than it can produce it, causing the body temperature to drop below 95°F (35°C). This can happen in cold environments, such as during outdoor activities like hiking, skiing, or swimming in cold water. Hypothermia can also occur in warmer environments if a person is wet or exposed to cold temperatures for an extended period. In this article, we will explore the five stages of hypothermia, their symptoms, and what to do if you or someone you know is experiencing hypothermia.
What is Hypothermia?
Hypothermia is a serious medical condition that can be life-threatening if not treated promptly. It occurs when the body’s core temperature drops below 95°F (35°C), causing the body’s metabolic processes to slow down. This can lead to confusion, disorientation, and eventually, loss of consciousness. Hypothermia can be caused by exposure to cold temperatures, wet clothing, or cold water. It can also be caused by certain medical conditions, such as hypothyroidism or diabetes.
Causes of Hypothermia
There are several causes of hypothermia, including:
- Exposure to cold temperatures
- Wet clothing or cold water
- Certain medical conditions, such as hypothyroidism or diabetes
- Age (older adults and young children are more susceptible to hypothermia)
- Medications (certain medications, such as beta-blockers, can increase the risk of hypothermia)
The Five Stages of Hypothermia
Hypothermia can be divided into five stages, each with distinct symptoms and characteristics. Understanding these stages is crucial in recognizing and treating hypothermia.
Stage 1: Mild Hypothermia (Body Temperature 90-95°F or 32-35°C)
In the first stage of hypothermia, the body temperature drops to between 90-95°F (32-35°C). The symptoms of mild hypothermia include:
- Shivering
- Confusion
- Dizziness
- Nausea and vomiting
- Fatigue
At this stage, the person may still be able to think clearly and respond to their environment. However, they may start to feel cold and uncomfortable.
Stage 2: Moderate Hypothermia (Body Temperature 82-90°F or 28-32°C)
In the second stage of hypothermia, the body temperature drops to between 82-90°F (28-32°C). The symptoms of moderate hypothermia include:
- Increased shivering
- Confusion and disorientation
- Slurred speech
- Difficulty walking or moving
- Numbness or tingling in the extremities
At this stage, the person may start to experience more severe symptoms, including confusion and disorientation. They may also start to lose coordination and have difficulty walking or moving.
Stage 3: Severe Hypothermia (Body Temperature 70-82°F or 21-28°C)
In the third stage of hypothermia, the body temperature drops to between 70-82°F (21-28°C). The symptoms of severe hypothermia include:
- Loss of consciousness
- Confusion and disorientation
- Slurred speech
- Difficulty breathing
- Cardiac arrhythmias
At this stage, the person may lose consciousness and experience more severe symptoms, including difficulty breathing and cardiac arrhythmias.
Stage 4: Profound Hypothermia (Body Temperature 50-70°F or 10-21°C)
In the fourth stage of hypothermia, the body temperature drops to between 50-70°F (10-21°C). The symptoms of profound hypothermia include:
- Coma
- Cardiac arrest
- Respiratory failure
- Seizures
At this stage, the person may experience a coma, cardiac arrest, or respiratory failure. This stage is life-threatening and requires immediate medical attention.
Stage 5: Near-Death Hypothermia (Body Temperature below 50°F or 10°C)
In the fifth and final stage of hypothermia, the body temperature drops below 50°F (10°C). The symptoms of near-death hypothermia include:
- Cardiac arrest
- Respiratory failure
- Coma
- Death
At this stage, the person is at risk of death due to cardiac arrest, respiratory failure, or coma.
Treatment of Hypothermia
The treatment of hypothermia depends on the stage and severity of the condition. In general, the goal of treatment is to warm the person up slowly and safely.
Mild Hypothermia
For mild hypothermia, treatment may include:
- Removing wet clothing and replacing it with warm, dry clothing
- Providing warm drinks, such as tea or hot chocolate
- Using a warm blanket or sleeping bag to keep the person warm
- Moving the person to a warm environment
Moderate to Severe Hypothermia
For moderate to severe hypothermia, treatment may include:
- Calling emergency services for immediate medical attention
- Removing wet clothing and replacing it with warm, dry clothing
- Providing warm drinks, such as tea or hot chocolate
- Using a warm blanket or sleeping bag to keep the person warm
- Immersing the person in warm water (around 104°F or 40°C) for 20-30 minutes
- Using a heating pad or warm compresses to warm the person up
Prevention of Hypothermia
Prevention is key in avoiding hypothermia. Here are some tips to prevent hypothermia:

What is hypothermia and how does it occur?
Hypothermia is a medical condition that occurs when the body loses heat faster than it can produce it, causing the body temperature to drop below 95°F (35°C). This can happen in cold environments, such as outdoors in winter or in cold water, or in situations where the body’s ability to regulate its temperature is impaired, such as in cases of certain medical conditions or the use of certain medications.
Hypothermia can also occur in warmer environments if the body is wet or exposed to cold air or water. For example, a person who is swimming in warm water but is exposed to cold air may still develop hypothermia. Additionally, hypothermia can occur in people who are not dressed warmly enough for the cold weather, or who are not able to move around to generate body heat.
What are the five stages of hypothermia?
The five stages of hypothermia are mild, moderate, severe, profound, and near-death. Each stage is characterized by a range of symptoms, from mild confusion and shivering in the early stages to loss of consciousness and cardiac arrest in the later stages. Understanding the different stages of hypothermia is important for recognizing the condition and providing proper treatment.
The stages of hypothermia are based on the body temperature, with mild hypothermia occurring at temperatures between 90°F (32°C) and 95°F (35°C), moderate hypothermia between 82°F (28°C) and 90°F (32°C), severe hypothermia between 70°F (21°C) and 82°F (28°C), profound hypothermia below 70°F (21°C), and near-death hypothermia below 60°F (16°C).
What are the symptoms of mild hypothermia?
The symptoms of mild hypothermia include shivering, confusion, and difficulty speaking. People with mild hypothermia may also experience numbness or tingling in their extremities, such as their fingers and toes. They may also feel cold to the touch and have a slow pulse. In some cases, people with mild hypothermia may also experience nausea and vomiting.
If left untreated, mild hypothermia can progress to more severe stages, so it is essential to seek medical attention if symptoms persist or worsen. Treatment for mild hypothermia typically involves warming the person up with blankets or warm clothing, and providing warm drinks, such as tea or hot chocolate.
How is hypothermia treated?
Treatment for hypothermia depends on the severity of the condition. For mild hypothermia, treatment typically involves warming the person up with blankets or warm clothing, and providing warm drinks, such as tea or hot chocolate. In more severe cases, hospitalization may be necessary to provide more intensive treatment, such as the use of warm IV fluids or a warm water bath.
In cases of severe hypothermia, treatment may also involve the use of medications to help warm the body, such as vasodilators to increase blood flow to the extremities. In some cases, people with severe hypothermia may also require mechanical ventilation to support their breathing.
Can hypothermia be prevented?
Yes, hypothermia can be prevented by taking steps to stay warm in cold environments. This includes dressing warmly, staying dry, and avoiding cold water or cold air. It is also essential to stay active and move around to generate body heat. Additionally, people who are at risk of hypothermia, such as the elderly or young children, should be monitored closely in cold weather.
Prevention is key to avoiding hypothermia, and there are many simple steps that can be taken to stay safe in cold weather. For example, wearing a hat and gloves can help to prevent heat loss from the head and hands, while staying indoors during extreme cold snaps can help to avoid exposure to cold temperatures.
Who is at risk of developing hypothermia?
Certain groups of people are at higher risk of developing hypothermia, including the elderly, young children, and people with certain medical conditions, such as diabetes or heart disease. People who are homeless or who do not have access to warm clothing or shelter are also at higher risk. Additionally, people who engage in outdoor activities, such as hiking or skiing, are at risk of developing hypothermia if they are not properly dressed or prepared.
Other groups of people who are at risk of developing hypothermia include people who are taking certain medications, such as beta-blockers or sedatives, which can impair the body’s ability to regulate its temperature. People who have a history of hypothermia are also at higher risk of developing it again.
What should I do if I suspect someone has hypothermia?
If you suspect someone has hypothermia, it is essential to seek medical attention immediately. While waiting for medical help to arrive, you can help to warm the person up by removing any wet clothing and providing warm blankets or clothing. You can also provide warm drinks, such as tea or hot chocolate, but avoid giving the person any hot liquids or foods.
It is also essential to monitor the person’s vital signs, such as their pulse and breathing rate, and to keep them calm and still. If the person is unconscious, you should call for emergency medical help and begin CPR if necessary.
