Cold weather essentials include items that help keep you warm and safe during low temperatures. Key items are insulated jackets, thermal layers, and waterproof boots. Accessories like hats, gloves, and scarves are also important to protect extremities from the cold. Additionally, having a reliable heating system in your home is crucial. Blankets and hot water bottles can provide extra warmth, while moisturizers help prevent dry skin caused by cold air. It's also wise to keep an emergency kit with flashlights and batteries in case of power outages during winter storms.
