Hypothermia while caving is a serious issue that can affect even the most experienced explorers. When you’re deep underground, the temperature can drop significantly, leading to dangerous conditions. Hypothermia happens when your body loses heat faster than it can produce it, making it hard to stay warm.
Though we don’t often consider it in daily life, hypothermia can happen at any time, particularly on extended caving expeditions. Envision yourself in a cave where the temperature is significantly lower than you had expected. This may seem overwhelming and terrifying.
Thankfully, there are measures you can take to keep yourself safe and secure. We’ll go into detail about hypothermia during caving, how to avoid it, and what to do in case you find yourself in a dangerous situation in the sections that follow.
Understanding Hypothermia While Caving
What is Hypothermia?
When your body temperature falls below 95°F (35°C), you become hypothermic. It’s a dangerous illness that could be fatal if left untreated. The combination of cold and moisture during a cave visit can increase your risk of hypothermia.
Why Caving Increases the Risk
Naturally, cave temperatures are low, typically between 40°F and 50°F (4°C and 10°C). Your body can lose heat quickly if you are wet or improperly dressed. The temperature drops as you go deeper, raising your risk of hypothermia.
Preventing Hypothermia
To avoid hypothermia while caving, follow these steps:
- Dress in Layers: Wear thermal base layers, waterproof outer layers, and insulated clothing.
- Stay Dry: Avoid getting wet. Water can quickly chill your body.
- Keep Moving: Physical activity generates heat, so keep moving to stay warm.
- Monitor the Temperature: Be aware of the cave’s temperature and adjust your clothing accordingly.
- Have Emergency Gear: Bring extra warm clothing and emergency supplies.
Symptoms and Stages of Hypothermia
Recognizing the Symptoms
Hypothermia symptoms can vary depending on the stage. The early signs include shivering, confusion, and slurred speech. As it progresses, you might experience extreme fatigue, drowsiness, and difficulty moving.
The 5 Stages of Hypothermia
- Mild Hypothermia: Shivering, cold and pale skin, rapid breathing.
- Moderate Hypothermia: Intense shivering, confusion, slurred speech, impaired coordination.
- Severe Hypothermia: No shivering, numbness, unconsciousness, slow heart rate.
- Near Death: Loss of consciousness, very weak pulse, risk of cardiac arrest.
- Fatal Hypothermia: Irreversible damage, death.
What to Do if You or Someone Else Shows Symptoms
If you or someone else shows signs of hypothermia, act quickly:
- Get Out of the Cold: Move to a warmer place immediately.
- Remove Wet Clothing: Replace with dry, warm clothes.
- Warm Up Gradually: Use warm blankets, heating pads, or warm (not hot) drinks.
- Seek Medical Help: Hypothermia can be severe, so don’t hesitate to get professional medical assistance.

You Might Like to Know
What is the temperature of caving?
Cave temperatures can vary but are generally between 40°F to 50°F (4°C to 10°C). They can be even colder depending on the depth and location of the cave.
What are three warning signs of hypothermia?
Three warning signs of hypothermia are intense shivering, confusion or disorientation, and slurred speech. These indicate that your body is struggling to maintain a normal temperature.
At what point is hypothermia fatal?
Hypothermia becomes fatal when the body’s core temperature drops below 70°F (21°C), leading to severe cardiac and respiratory issues.
Is dying of hypothermia painful?
Dying from hypothermia can be painful, but often, individuals feel numbness and confusion, which might lessen the sensation of pain.
How long can a human survive hypothermia?
Survival time depends on factors like the severity of hypothermia, clothing, and environmental conditions. In extreme cases, survival can be less than an hour if immediate action is not taken.
Conclusion
Hypothermia while caving is a serious risk, but understanding it can help you stay safe. By dressing appropriately, staying dry, and recognizing early symptoms, you can protect yourself from the dangers of hypothermia. Remember to always be prepared and seek help if you need it. Stay warm, stay safe, and enjoy your caving adventures with confidence!
