Exposure to extreme cold can lead to serious health problems, the most common being frostbite and hypothermia. Here’s what to know.
First, know who’s at higher risk: the very young and very old, people with certain medical conditions or jobs that keep them outside for long periods of time. And finally, people who drink or smoke.
Next, know the symptoms. Frostbite usually starts as a “pins and needles” feeling in your extremities, so pay attention to your hands, feet, ears, nose and lips. If parts of your body start to feel frozen, maybe a burning sensation – seek medical attention immediately.
Hypothermia can affect the brain and the body’s ability to move. So watch for people who seem tired, confused, weak and shivering. If you think someone has hypothermia, take their temperature. If it’s lower than 95 degrees, get help fast.
