Hypothermia
Overview
Hypothermia is a dangerous drop in core body temperature resulting from prolonged exposure to cold, wind, or wet conditions. It impairs physical and cognitive function and can become life-threatening without intervention.
Key points
- Develops when heat loss exceeds heat production.
- Signs include shivering, confusion, slurred speech, and fatigue.
- Exacerbated by wind chill, wet clothing, and low energy intake.
- Treatment involves warming, sheltering, and insulating the body.
- Can occur in cool, wet conditions even above freezing temperatures.
Details
Hypothermia occurs when environmental conditions, inadequate insulation, or exhaustion prevent the body from maintaining its normal core temperature. Wetness accelerates heat loss dramatically, especially in windy conditions. Early recognition is essential, as symptoms can progress quickly.
Preventive measures include layering appropriately, minimizing prolonged exposure to wet conditions, maintaining caloric intake, and seeking shelter during storms. Backcountry travelers remain attentive to weather changes and personal energy levels to reduce risk.
