People can die of hypothermia even when the temperatures are above freezing. (A notable instance occurred in 1964 in England). Note that "severe hypothermia causes cardiac instability". Drinking warm sweet liquids can help someone recover faster, but avoid alcoholic or caffeinated beverages. Paradoxical undressing is when hypothermic (aka "cold stupid") people remove articles of clothing even as they get colder. This has resulted in people with hypothermia being misdiagnosed as victims of sexual assault.
