"Whiskey warms the blood and can prevent hypothermia."
BUSTED: Never give booze to someone who is, or may be, hypothermic. Alcohol is a vasoconstrictor, which means it limits the flow of blood. Hot chocolate is a better drink, but beverages aside, nothing beats skin-on-skin rewarming. I know, Saint Bernards carried casks of brandy around their necks for avalanche victims, but consider this: we also used to think the world was flat. Skip the alcohol in a cold-weather emergency.
