||Get a humidifier if you have eczema. Especially in the winter, dry air can dry skin out and it can actually cause eczema. With a humidifier, moisture is pumped into the air. This make it less likely that your skin dries out and that eczema flares up.
Buy a good humidifier and use it when the air is dry. You might use if year round in a dry, arid climate. If you live in a humid climate, you might only need to use it in the winter when your heater is on, pumping out dry, hot air which quickly dries out skin.
