If the injury is not better in 48 hours, or if your injury worsens, see your doctor. Layer windproof and waterproof clothing and wear good insulators like wool and poly-propylene. To keep kids warm, dress them in thermal socks, thermal insulated boots and snowsuits and take care to make sure their hands, necks, heads and ears are well covered. Also, when kids are playing outside, make sure to check on them frequently. Know the signs of frostbite.
Frostbite is the freezing of skin or underlying tissues that occurs from prolonged exposure to cold.
Heed the early warning signs of frostbite to prevent it altogether, says Dr. Dokubo. If exposure continues and the skin turns white or blue or becomes hard and cold, seek medical attention immediately. Careful rewarming and antibiotic treatment may be necessary to prevent infection and permanent tissue damage. Avoid the flu. Flu shots are highly recommended for adults ages 50 and older, those with chronic health conditions and health care workers.
