Extreme Cold (Hypothermia) Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C). Hypothermia (hi-poe-THUR-me-uh) occurs as your body temperature passes below 95 F (35 C). When your body temperature drops, your heart, nervous system and other organs can't work normally. Left untreated, hypothermia can eventually lead to complete failure of your heart and respiratory system and to death.
Symptoms: Mild hypothermia Signs and symptoms of mild hypothermia include: · Shivering · Dizziness · Hunger · Nausea · Faster breathing · Trouble speaking · Slight confusion · Lack of coordination · Fatigue · Increased heart rate Moderate to severe hypothermia As your body temperature drops, signs and symptoms of moderate to severe hypothermia include: · Shivering, although as hypothermia worsens, shivering stops
Treatments First-aid care · Be gentle. When you're helping a person with hypothermia, handle him or her gently. Limit movements to only those that are necessary. Don't massage or rub the person. Excessive, vigorous or jarring movements may trigger cardiac arrest. · Move the person out of the cold. Move the person to a warm, dry location if possible. If you're unable to move the person out of the cold, shield him or her from the cold and wind as much as possible.
