FALSE: A hypothermia victim should be to have some alcohol to warm up the body.
WHY NOT: Alcohol does not actually increase body temperature, in fact it lowers it, which worsens hypothermia. Someone suffering from hypothermia can become drowsy and alcohol will mask symptoms.
WHAT TO DO: Keep the victim dry and warm using blankets, towels or coats instead! Be very careful how you move the casualty as an extremely low temperature can make them prone to a heart attack.
