Which is a common sign of hypothermia?

• A. Nausea
• B. Shivering, confusion, slurred speech
• C. Headache only
• D. Rapid heartbeat without other signs

Answer: (B)

Hypothermia happens when the body loses heat faster than it can produce it, so the core temperature drops. The most telling early signs are shivering—the body's natural heat-producing response—paired with changes in brain function, such as confusion and slurred speech. This combination shows both the physical reaction to cold and the nervous system being affected, which is why it’s the best indicator of hypothermia. In paddling situations, cold water, wind, and wet gear can bring these signs on quickly, so noticing someone who is both shivering and showing confusion or slurred speech means you should act fast to warm them and seek help. Nausea, headache, or a rapid heartbeat without other signs can occur in various situations and don’t point as clearly to hypothermia as the trio described.
