Stages of Hypothermia: Mild, Moderate, and Severe Explained
Cold weather can be way more than uncomfortable—it can be dangerous. Understanding the stages of hypothermia is crucial, especially if you or a loved one may be at risk during the colder months. At White Rock Medical Center, we provide severe hypothermia treatment in Dallas, TX, along with the emergency care support you may need.
Whether you’re outdoors hiking, working in freezing temperatures, or dealing with chronic cold exposure, knowing how hypothermia progresses could save a life.
Let’s break it down into three clear stages: mild, moderate, and severe.
What Is Hypothermia?
Hypothermia occurs when the body loses heat way faster than it can produce it, hence causing your core body temperature to go below 95°F (35°C). Normal body function starts to slow, and without immediate help, it can become life-threatening.
Common Causes:
- Prolonged exposure to cold air or water
 - Wet clothing in cold weather
 - Living in poorly heated homes
 - Certain medications or health conditions
 
Stage 1: Mild Hypothermia
Mild hypothermia is often overlooked. It develops slowly, and symptoms may be subtle—especially in older adults or those who are already ill.
Mild hypothermia symptoms include:
- Shivering
 - Cold, pale skin
 - Numbness in hands and feet
 - Slight confusion or forgetfulness
 - Fast breathing or heart rate
 - Trouble speaking clearly
 
Shivering is the body’s first defense against cold. If caught early, you can often reverse mild hypothermia without medical help by warming the person gently.
At-home steps to manage mild symptoms:
- Move indoors or to a warm area
 - Remove wet clothing
 - Wrap in blankets
 - Offer warm (not hot) drinks
 - Use warm compresses on the chest or neck
 
But if symptoms persist or worsen, it’s time to get medical help.
Stage 2: Moderate Hypothermia
This stage signals a bigger problem. The body’s ability to regulate temperature breaks down.
Signs to watch for:
- Shivering slows or stops
 - Confusion increases
 - Slurred speech
 - Lack of coordination
 - Drowsiness or sudden fatigue
 - Weak pulse
 
The danger here is that people may not realize how serious their condition is. Their judgment is impaired, and they may try to remove warm clothing or lie down outdoors.
Chronic hypothermia symptoms often resemble moderate signs but develop over days or weeks. This happens in people with long-term exposure to cold—like the elderly in under-heated homes or those without proper shelter.
Stage 3: Severe Hypothermia
Severe hypothermia is a true emergency and needs immediate medical attention.
Symptoms include:
- Barely detectable or no shivering
 - Unconsciousness
 - Shallow or slowed breathing
 - Dilated pupils
 - Irregular heartbeat or very weak pulse
 - Risk of cardiac arrest
 
A person may appear dead, but emergency help should be given until proven otherwise. Call 911 and start gentle warming while waiting for professional care.
If you’re near a trusted hospital in Dallas, TX, do not wait. Go immediately. This is where rapid rewarming and close monitoring are essential.
What Happens During Emergency Treatment?
At White Rock Medical Center, our team is trained to provide hypothermia emergency care in Dallas, TX, for all three stages, especially when severe. Here’s what treatment may involve:
- Rewarming the body using heated IV fluids
 - Warming blankets or air
 - Oxygen therapy
 - Continuous heart monitoring
 - CPR or defibrillation if the heart stops
 
Recovery depends on how low the body temperature fell and how quickly treatment began. Some people recover quickly, while others may need longer hospital care.
When to Go to the Hospital
You shouldn’t guess when it comes to hypothermia. If someone:
- Is shivering uncontrollably
 - Shows mental confusion
 - Has cold, bluish skin
 - Becomes drowsy or unresponsive
 
Then don’t wait. Go to an emergency hospital in Dallas, TX, immediately. Hypothermia can spiral quickly from manageable to critical.
Who’s at Higher Risk?
Some people are more vulnerable to hypothermia due to age or health.
High-risk groups:
- Seniors with limited mobility
 - Infants and small children
 - People with chronic illnesses (like diabetes or thyroid issues)
 - Homeless individuals
 - Outdoor workers or enthusiasts
 - Those taking medications that affect body temperature
 
If you or a loved one falls into one of these groups, take extra steps to stay warm and check in often during colder months.
6 Quick Tips to Prevent Hypothermia
- Dress in layers. Always wear a hat and gloves.
 - Avoid alcohol in cold weather. It may make you feel warm, but it increases heat loss.
 - Stay dry. Wet clothing accelerates heat loss.
 - Limit time outdoors. Especially in wind, rain, or snow.
 - Warm your home properly. Keep indoor temperatures above 68°F.
 - Watch others. Check on elderly neighbors and family regularly.
