Winter emergencies can escalate quickly in cold conditions. Understanding the signs, prevention, and treatment of cold-weather medical issues is essential for every winter camper.
Dehydration is one of the most common and underappreciated winter hazards. Cold, dry air pulls moisture from your body with every breath. You may not feel thirsty, but you're losing water constantly. Symptoms include headache, fatigue, dark urine, dizziness, and decreased coordination.
Prevention: Drink frequently throughout the day. Warm liquids help maintain core temperature and encourage drinking. Avoid caffeine and alcohol, which promote fluid loss.
Yes, overheating is a winter risk. Vigorous activity like snowshoeing uphill in full winter gear can cause excessive sweating. Wet clothing then conducts heat away from the body rapidly when you stop moving.
Prevention: Ventilate by opening zippers, removing hat, and adjusting layers before you start sweating. It's easier to prevent overheating than to deal with wet clothing later.
Hypothermia occurs when body core temperature drops below 95°F (35°C). It is the most serious cold-weather emergency.
Mild (90–95°F): Shivering, poor coordination, slurred speech, poor judgment, apathy. The person may not recognize their own symptoms.
Moderate (82–90°F): Violent shivering that may stop, muscle rigidity, confusion, drowsiness, slow pulse and breathing.
Severe (below 82°F): No shivering, unconsciousness, very slow or irregular pulse, may appear dead. This is a life-threatening emergency.
Remove from cold/wind/wet. Replace wet clothing with dry. Insulate from ground. Provide warm (not hot) drinks if conscious. Apply heat to core areas (neck, armpits, groin). Handle gently — rough handling can cause cardiac arrest in severe cases. Seek medical help immediately for moderate or severe hypothermia.
