Hypothermia is a condition that occurs when the body loses heat faster than it can produce it. It often develops when someone is exposed to cold weather or water for prolonged periods without adequate protection. When body temperature drops below 35°C (normal is 37°C), vital organs like the heart and brain can be affected. This condition is a medical emergency, and if left untreated, it can lead to organ failure and even death.

Causes of Hypothermia
Hypothermia is most common in countries with winter seasons where snow is prevalent. However, it can also occur in warmer climates, such as the Philippines, under specific circumstances:
- Prolonged exposure to wet clothing. Damp clothes can accelerate heat loss from the body.
- Staying outdoors without sufficient protection during cold weather. This includes exposure during storms or cold nights.
- Submersion in cold water. Even brief exposure can lead to rapid body heat loss.
- Strong air conditioning. Prolonged exposure to cold indoor environments can also cause hypothermia.
Symptoms of Hypothermia
The first and most common symptom of hypothermia is shivering, an involuntary reaction to generate heat. As the condition progresses, other symptoms may include:
- Dizziness
- Hunger
- Rapid breathing
- Difficulty speaking
- Confusion
- Poor coordination
- Fatigue
- Rapid heartbeat
- Weak pulse
- Gradual loss of consciousness
Since hypothermia progresses slowly, individuals affected by it often don’t realize they are in danger. Recognizing these symptoms early is critical as hypothermia is a medical emergency requiring immediate attention.
Treatment for Hypothermia
The treatment for hypothermia focuses on restoring body heat. Unlike heatstroke, where the aim is to lower body temperature, hypothermia requires warming interventions. Here are some steps to treat someone experiencing hypothermia:
- Minimize movement. Avoid sudden or vigorous movements, as they can trigger cardiac arrest.
- Move the individual to a warmer environment. Remove them from the cold area.
- Remove wet clothing. Replace them with dry, warm garments.
- Wrap the person in blankets. This helps retain body heat.
- Share body heat. Remove your own clothing and embrace the person to transfer warmth.
- Provide warm drinks. Offer warm liquids like soup or tea, but avoid alcohol or caffeine.
- Use warm compresses. Apply them to the chest, neck, or groin, but avoid direct heat sources like hot water bottles or heaters, which can cause burns or shock.
- Soak feet in warm water. This can help gently increase body temperature.
If the body temperature does not return to normal, seek medical assistance immediately. Hospitals may perform the following interventions:
- Warming blood through hemodialysis.
- Administering warmed intravenous fluids.
- Providing humidified oxygen.
How to Prevent Hypothermia
Preventing hypothermia involves keeping the body warm, especially during cold weather. Here are some tips:
- Wear thick clothing. Layer your clothing to trap heat.
- Avoid excessive physical activity. Sweating can make your clothes damp, increasing heat loss.
- Keep your clothes dry. Change immediately if you get wet.
- Limit outdoor activities. Stay indoors during cold weather if possible.
- Use blankets when sleeping. Keep your body insulated at night.
- Avoid using fans or air conditioning. These can exacerbate cold conditions.
- Drink warm beverages. Opt for soups or teas to maintain your body temperature.
Hypothermia is preventable with proper preparation and awareness. By staying warm, recognizing early symptoms, and knowing how to respond, you can protect yourself and others from this life-threatening condition.
