Prolonged exposure to freezing temperatures can lead to hypothermia. Hypothermia is a medical emergency that causes a dangerously low body temperature and can be fatal if untreated.

Symptoms of hypothermia include confusion, dizziness, exhaustion, severe shivering, clumsiness, slurred speech or mumbling drowsiness, weak pulse, slow, shallow breathing and progressive loss of consciousness. County officials said to seek medical attention if experiencing these symptoms.

Additional Cold Weather Safety Tips

• Drive slowly and be on the lookout for hazardous travel with slick road conditions including possible ponding on roads and freeway off-ramps and minor flooding in low-lying or poor drainage areas.
• Unsheltered community members, older adults, children and those with access and functional needs should seek shelter now as they are at higher risks of hypothermia.
• Dress in layers, wear a hat, scarf, gloves and mittens, and waterproof, insulated boots to avoid hypothermia or frostbite.
• Get out of wet clothes as soon as possible to reduce the risk of hypothermia.
• Stay hydrated by drinking plenty of water with electrolytes.
• Avoid excessive consumption of alcohol and non-prescription medication if you will be staying outside as it may lead to death or serious injury.
