WOODBURY - Experts are reminding residents of the inherent risks of spending too much time outdoors amid the frigid temperatures.

Health hazards from prolonged exposure to the cold include hypothermia and frostbite, which could take hold within 30 minutes. Numbness or tingling could be indicative of frostbite settling in.

Dr. Steven Walerstien, NUMC'S chief medical officer says residents should try to avoid running outside. He also says 15 minutes should be the cutoff point for walking or shoveling. Walerstien then recommends drinking something warm afterward.

Experts advise wearing multiple layers, and to include a hat.

Temperatures are expected to make it down to zero and below around the Island on Friday.
