Humidifiers can be beneficial. However, be sure to clean the units according to the manufacturer's instructions to reduce molds and fungi. Protect yourself from the wind. Cover your face and use a petroleum-based balm for your lips. Avoid extreme cold.
Cold temperatures can cause skin disorders or frostbite in some people.
See a doctor immediately if you develop color changes in your hands or feet in association with pain or ulceration. If you develop extreme pain followed by loss of sensation in a finger or toe, you could have frostbite. Avoid excessive heat. Do not keep the heat in your home above 78 degrees. Besides adding to your heating bill, high temperatures deplete moisture from the air and contribute to winter itch.
