People most associate hypothermia with very cold days. But at temperatures in the 60s and 70s, it can easily happen if someone is wet, say doctors at the University of Tennessee - Lifestar Air Medical Helicopter Transport Service in Knoxville.
It's important to take steps to avoid hypothermia yourself. But because fellow-workers may not be aware that they need medical treatment, it's up to those nearby to help take care of them.
Watch for these symptoms in yourself and others: shivering, slurred speech, poor coordination, and confusion. When people with hypothermia stop shivering, they can lose consciousness and die if not treated.
To prevent hypothermia:
- Dress appropriately and stay dry. Wear several layers of clothing, and a wind-blocking jacket.
- In rain, cover yourself with a poncho or a plastic trash bag if that's all that is available. Water causes heat loss 30 times faster than air, according to the National Safety Council.
- If a co-worker or friend is shivering and behaving oddly, get the victim to a warmer place. If he is wet, get him dry. Until medical help arrives, use a blanket to warm the victim.
- Inexperienced campers and hikers can be hypothermia victims. If a fellow camper begins to shiver and do strange things these are likely warning signs.
