Know the Signs of Hypothermia! 🥶

As the winter months roll in and temperatures drop, we often find ourselves spending more time outdoors—whether it’s hiking, skiing, or simply enjoying a snowy day. However, with the cold weather comes the risk of hypothermia, a dangerous and potentially life-threatening condition that can develop when your body loses heat faster than it can produce it.

This informational campaign comes to you in partnership with the Stark County Community Action Agency.

What Is Hypothermia?

Hypothermia occurs when your body temperature drops below the normal range of 95°F (35°C). In cold environments, this can happen even if you’re not in freezing temperatures, especially if you’re wet, exposed to wind, or inactive. Your body’s core temperature is vital for normal organ function, and when it drops too low, it can lead to confusion, organ failure, and even death. That’s why it’s essential to spot the early symptoms of hypothermia and act fast.

Early Signs of Hypothermia: Shivering, Confusion, and Cold Extremities

The first signs of hypothermia can be subtle, but they shouldn’t be ignored. At this stage, your body is trying to conserve heat and maintain its temperature. Early symptoms include:

1. Shivering
   Shivering is one of the body’s first responses to cold. It’s a sign that your body is trying to generate heat by rapidly contracting your muscles. While shivering is a natural reaction, it’s important to note that once hypothermia progresses, shivering may stop, signaling a worsening condition.
2. Cold and Pale Skin
   Skin will begin to feel noticeably cold to the touch, and its color might change to a pale or even blue-ish tint due to reduced blood flow to extremities. The hands, fingers, toes, ears, and nose are especially susceptible to this.
3. Fatigue and Drowsiness
   A feeling of exhaustion and the desire to sleep, despite the cold, are early warning signs. As your body fights to preserve energy, your mental clarity begins to fade.
4. Confusion and Poor Coordination
   One of the early mental symptoms is confusion. As the body cools, your brain starts to function less efficiently. You may experience memory problems or trouble focusing on simple tasks. People suffering from hypothermia may appear disoriented, slurring their speech, or making poor decisions (like taking off clothes in an attempt to cool off, which is dangerous).
5. Rapid Breathing and Heart Rate
   As your body tries to maintain its core temperature, your heart rate and breathing rate may increase. This is an attempt by your body to compensate for the heat loss. But as hypothermia worsens, these signs may become irregular or slow.

Moderate to Severe Hypothermia: A Dangerous State

If hypothermia progresses past the early stages, it can become life-threatening. Here’s what to watch for if the condition worsens:

1. Intense Shivering or Shivering Stops
   As hypothermia worsens, the body can no longer maintain the intense shivering response. In some cases, shivering may completely stop. This is a sign that your body’s thermoregulation is failing, and your core temperature is dangerously low.
2. Weak Pulse and Slow Breathing
   The pulse may become weak and irregular, while breathing may slow down significantly. In extreme cases, the heart rate can become erratic, which could lead to cardiac arrest.
3. Severe Confusion or Loss of Consciousness
   Mental confusion can intensify to the point where the person may not respond to their name or simple commands. They may also begin to lose consciousness, which is a critical sign that immediate medical intervention is needed.
4. Uncontrollable Shivering or Rigid Muscles
   In some cases, muscles may become rigid and difficult to move. This happens when the body’s thermoregulation system fails to keep up, causing muscles to seize up. This can make it difficult or even impossible to walk or perform simple actions.
5. Skin Becoming Bluish or Mottled
   At this stage, skin may become blue, purple, or blotchy due to extreme lack of circulation. This is often a sign that the body’s organs are no longer getting the oxygen they need to function properly.
6. Frostbite
   Severe cold exposure can cause frostbite, particularly in extremities. This occurs when skin and tissue freeze, leading to numbness, blisters, and possible long-term damage. In advanced stages, frostbite can result in the loss of affected limbs.

What to Do If You Spot the Signs of Hypothermia

If you or someone you’re with shows signs of hypothermia, time is of the essence. Here’s what you should do:

1. Get Out of the Cold
   Move the person to a warmer, sheltered environment immediately. Avoid direct exposure to wind and moisture. If you’re outdoors, seek a building, car, or any shelter that can provide warmth.
2. Remove Wet Clothing
   Wet clothing should be removed, as it can continue to draw heat away from the body. Replace it with dry, warm clothes, including socks, gloves, and hats.
3. Warm Up Gradually
   Use blankets, warm (not hot) water bottles, or heating pads to gradually warm the body. Focus on the core area—chest, neck, and groin—since these are where the major blood vessels are located.
4. Offer Warm, Non-Alcoholic Fluids
   If the person is awake and alert, offer warm, non-alcoholic beverages like tea, broth, or water. Alcohol and caffeine should be avoided, as they can cause further heat loss by dilating blood vessels.
5. Seek Medical Attention
   Hypothermia is a medical emergency, and even mild cases should be evaluated by a healthcare provider. Moderate and severe hypothermia require immediate medical intervention, such as rewarming techniques in a hospital.

Prevention Is Key

The best way to protect yourself and others from hypothermia is prevention. Dress in layers, stay dry, and avoid prolonged exposure to cold weather. Pay attention to the wind chill factor, as it can lower your body’s temperature faster than you might think.
