Warning signs

The CDC lists shivering, exhaustion or feeling very tired, confusion, fumbling hands, memory loss, slurred speech, and drowsiness as warning signs of hypothermia in adults.

Not only in deep cold

The CDC says hypothermia can occur at cool temperatures, above 40°F, if a person is wet from rain, sweat, or cold water and becomes chilled.

Shivering is a signal

The CDC says shivering is an early sign that your body is losing heat, and constant shivering means you need to find shelter and get warm.

Get help

The CDC says that if a person's temperature is below 95°F, get medical attention immediately. IHEA-USA hunter education says to remove the person from cold, windy, and wet conditions and to re-warm gradually. Call 911 in an emergency.
