Chicago, IL – As Illinois prepares for the approaching winter season, residents across Chicago, Rockford, Springfield, Peoria and communities throughout the Prairie State are being reminded of two potentially life threatening cold weather conditions: frostbite and hypothermia. Although both develop from exposure to cold, they affect the body differently and can become serious medical emergencies.
According to the National Weather Service, dressing in layers, covering exposed skin and limiting time outdoors can help prevent cold related injuries. Strong winds, wet clothing and prolonged exposure can increase the danger, particularly during Illinois' colder winter months.
Frostbite vs. Hypothermia: What's the Difference?
Frostbite occurs when skin and underlying tissues freeze, most commonly affecting fingers, toes, ears, noses and other exposed areas.
Early warning signs include numbness, tingling, unusual skin discoloration and skin that feels hard or waxy. Severe frostbite can cause permanent tissue damage.
Hypothermia, meanwhile, develops when the body's core temperature drops below 95 degrees Fahrenheit.
Symptoms include uncontrollable shivering, confusion, slurred speech, extreme fatigue and poor coordination. In severe cases, shivering may stop, signaling a potentially life threatening emergency.
Why Illinois Residents Should Pay Attention
Illinois experiences significant winter temperature differences between northern and southern communities.
Chicago and northeastern Illinois can experience strong winds off Lake Michigan, while Rockford, DeKalb and other northern communities frequently face prolonged freezing conditions.
Central and southern Illinois can also experience dangerous cold, especially during Arctic air outbreaks.
Hypothermia can develop even when temperatures remain above freezing, particularly when cold rain, wind or wet clothing accelerate body heat loss.
What Should Residents Do?
Anyone showing signs of hypothermia needs immediate medical attention. Call 911, move the person indoors, remove wet clothing and wrap them in dry blankets while awaiting emergency assistance.
For suspected frostbite, avoid rubbing affected skin or applying direct heat. Seek medical attention promptly.
Residents should also check on older adults, protect pets and prepare emergency supplies for winter travel.
The critical difference: Frostbite freezes and damages body tissue, while hypothermia dangerously lowers internal body temperature. Both conditions can occur simultaneously.
