When the body loses heat faster than it can produce it, hypothermia occurs. This dangerous condition happens when a person’s core body temperature drops below 95°F (35°C).

Although it commonly affects individuals who are exposed to extremely cold weather for extended periods, hypothermia can also occur in mild temperatures under certain circumstances. It is important to recognize the early signs of hypothermia to seek immediate medical attention and prevent further complications.

1. Shivering and Clumsiness

One of the earliest signs of hypothermia is uncontrollable shivering. As the body tries to generate heat, muscles contract and relax rapidly, causing shivering. Beyond shivering, sufferers also experience clumsiness and difficulty with fine motor skills.

This happens because the body conserves energy by reducing blood flow to the muscles in non-essential areas.

2. Cold and Pale Skin

Hypothermia reduces blood flow to the skin’s surface to prioritize organs’ blood supply. This leads to cold, pale, or bluish skin. The body’s extremities, such as the fingers, toes, ears, and nose, are usually the first to be affected.

The skin may also feel numb or tingly due to impaired nerve function.

3. Fatigue and Drowsiness

As hypothermia progresses, individuals often feel increasingly tired and drowsy. The drop in body temperature impairs the brain’s functioning, leading to reduced energy levels and feelings of exhaustion.

Fatigue and drowsiness can be dangerous signs, as they may cause sufferers to fall asleep in cold environments, exacerbating the condition.

4. Slurred Speech

As body temperature drops, hypothermia affects the central nervous system, including the brain. This can result in slurred speech, difficulty articulating words, or speaking slowly.

The person may also seem confused or disoriented, struggling to carry out simple tasks or respond to questions appropriately.

5. Intense Hunger and Increased Urination

The body responds to hypothermia by increasing metabolic activity to generate heat. This heightened metabolism can cause individuals to experience intense hunger even after eating a substantial meal.

Additionally, hypothermia stimulates the kidneys, leading to increased urine production. These symptoms are often overlooked or attributed to other causes.

6. Rapid Breathing and Heart Rate

As hypothermia progresses, breathing and heart rate become rapid and irregular. The body attempts to maintain its core temperature by increasing blood circulation. This can result in a faster heart rate and shallow, quick breaths.

The respiratory system becomes strained as the body loses heat rapidly.

7. Nausea and Vomiting

In some cases, hypothermia can trigger nausea and vomiting. The effects of hypothermia on the digestive system can lead to a loss of appetite, stomach discomfort, and gastrointestinal distress.

These symptoms, combined with other early signs, should not be ignored and warrant immediate medical attention.

8. Difficulty Concentrating

Hypothermia affects cognitive function and impairs an individual’s ability to think clearly. As body temperature drops, the brain’s ability to prioritize tasks and make decisions becomes compromised.

Those experiencing early-stage hypothermia may have difficulty concentrating, solving problems, and performing basic mental tasks.

9. Increased Anxiety and Confusion

As hypothermia progresses, individuals may experience heightened anxiety and confusion. This can manifest as restlessness, irritability, or irrational behavior.

The lack of proper blood flow to the brain and the associated drop in body temperature contribute to these psychological symptoms. Friends and family members should be vigilant for these signs and seek medical assistance promptly.

10. Weak Pulse and Low Blood Pressure

In severe cases, hypothermia can lead to a weak, shallow pulse and low blood pressure. These signs indicate a critical condition that requires immediate emergency medical attention.

A weak pulse and low blood pressure are signs that the body’s core temperature has dropped dangerously low and that vital organs may be at risk.
