When the first cold weather hits, my lips get extremely chapped – just one sign of what dry air can do to skin. And those with sensitive skin, such as those with eczema, are particularly vulnerable to the effects of dry air. Cold air is not the only dry air we have to worry about. Heated air in the home is also extremely drying to the skin. This is what most affects my two young children, and they don't even suffer from allergies or dry skin normally.

To prevent dry skin and eczema in the winter, check out the following helpful tips from renowned pediatrician Dr. Sears for helping "winterize" children's skin:

• Apply a moisturizer. Moisturizers seal in moisture and also bring water up from lower layers of the skin, both of which contribute to healthy skin. Many moisturizers contain ingredients that can irritate sensitive skin, however, including fragrances, dyes, and other chemicals. Make sure to use a fragrance-free, hypoallergenic moisturizer, such as Vanicream Skin Cream.

• Seal in moisture after baths. Applying moisturizer when the skin is somewhat damp is the best way to seal in moisture and keep the skin hydrated.

• Moisturize the skin during air travel. Air on planes is exceptionally dry. Be sure to apply moisturizers before flying, after, and maybe even during the flight. This will go a long way in preventing hours of dry air from causing skin problems that could lead to eczema.

• Hydrate through drinking liquids. Have your child drink a lot of water throughout the day. This helps keep skin hydrated.

• Vaporize the air. Using a humidifier increases ambient moisture in the air, preventing the effects of dry air. As an added benefit, humidification also makes the air feel warmer.

• Eat seafood. Fish is high in skin-nourishing nutrients such as omega-3 oils, and vitamins A and D. Omega-3s, especially, guard against inflammatory reactions, and may also be given as supplements.

• Eat lots of fruits and vegetables. Antioxidant-rich foods (think foods with lots of color like blueberries) guard against wear and tear of the skin, helping protect it from the effects of dry air.
