“Children, the elderly, and people with disabilities or special medical needs are especially vulnerable during cold weather,” Dr. Muntu Davis, Los Angeles County Public Health’s Health Officer, said in a statement.

When temperatures drop, people should not use stoves, barbecues or ovens to heat their homes, health officials said.

People should instead dress in layers of warm clothes when outside; protect outer extremities with hats, scarves, gloves and socks; check on sick or elderly family, friends on neighbors; and bring pets indoors overnight.

Freezing temperatures raises the risk of hypothermia and frostbite. Another danger from cold is the attempt to keep homes warm with unapproved sources that can produce carbon monoxide.
