Cold-related Injury

Cold weather can be harmful to your health. While the health risks related to cold are higher for certain groups (such as people who work outdoors, people with pre-existing heart conditions or respiratory illnesses, older adults, infants, young children, and those who are experiencing homelessness), everyone is potentially at risk. Fortunately, most cold-related injuries can be prevented or treated if you are aware of the risks, signs, and symptoms. This information can help you to plan ahead, and take action to protect yourself and your family.

Cold weather can result in the development of cold-related injuries, such as windburn, frostnip, frostbite and hypothermia.

Windburn

Hypothermia is a medical emergency. Call 911 immediately if you suspect someone may have hypothermia.

Do not fight shivering, it’s one of the ways the body increases its core temperature.
