If help or a hospital is unavailable, wrap the person in warm blankets and take to a warm shelter. Try to avoid jostling the person when transporting. This may affect heart rhythm. Remove wet clothing and wrap the person in warm, dry blankets. Use hot water bottles or another person's body next to the victim to warm the victim.
Commercial sport drinks with a moderate amount of sugar are also acceptable.
Stretch cramped muscles. Nausea, weakness, light headedness, and possibly fainting without prolonged loss of consciousness. Very painful cramps may follow strenuous activity. Loosen or remove most clothing. Apply cool, wet compresses to head and torso.
