The Red Cross advises keeping homes heated and plumbing insulated to prevent freezing pipes, while outside, individuals should dress in layers to avoid frostbite and hypothermia. Warning signs include numbness and confusion, necessitating immediate action to warm the body. Special care is needed for the young and elderly, who are more vulnerable to cold-related illnesses.
