As the weather grows colder, you may notice your body getting more itchy – or in some cases, skin flaking off or even cracking, particularly in such areas as your elbows and knees.
Unless it’s indicative of such diseases as psoriasis, eczema or dermatitis – in which case hopefully you’re already seeing a dermatologist – dry skin in and of itself is nothing to be too concerned about … although the itchiness and appearance may be unpleasant. The reason for dry skin during the cold months is simple: cold air holds less moisture, which means your skin will become drier. Indoor heaters can also dehydrate your skin.
To avoid such developments, I recommend the following:
Take brief, lukewarm showers or baths. This may seem counterintuitive when it’s cold outside, but just as hot air will dry out your skin, so too will hot water, which can leach out your body’s natural oils. Keeping the water temperature down will prevent additional dehydration, as will keeping your bathing brief. Pat yourself dry afterwards.
Apply moisturizing ointments or creams after drying off. I recommend doing this over your entire body each time you bathe. Try using thicker products instead of thinner ones, which tend to be watered down don’t have as great an effect. Lotions, which typically contain more water than oil, are also generally less effective for the same reason.
Use a humidifier. Such a device can be a great help throughout the day. When the environment around you is drier, your skin gets drier, too. And outdoor elements aren't the only factor — the heaters we turn on when the temperature drops can dry out the indoor air too.
Remember the age factor. The previous steps are encouraged for everyone, but keep in mind that as we age our skin naturally produces less oil and decreases our ability to retain moisture. Older people may want to consult with a dermatologist to make sure they’re taking the proper steps to avoid or reduce dry skin.
Don’t forget the sunscreen. Most of us are used to applying a sunscreen with an SPF of at least 30 during the summer. But just because you’re not lying on a beach doesn’t mean you should forego sunscreen during the winter. The sun and its UV rays are still there, even if it’s less intense, and while you’re usually well-wrapped when going outside (hat, coat, gloves), there may still be parts of your body exposed to the sun. Again, an SPF of 30 blocks approximately 97% of the sun’s rays.
What if you’ve already got dry-skin symptoms? I suggest the following steps:
Moisturize well at least 1 to 2 times a day. Moisturizing ointments and petroleum jelly may be the best solution, as they contain no water to dilute them.
Avoid products that contain alcohol and scents, such as deodorizing soaps; the chemicals in the latter can further dry out your skin.
Stay hydrated. Making sure you drink plenty of water is always a good idea; during the winter you can further avoid developing dry skin by drinking four to six cups of plain water each day. Your physician can help further refine that amount depending on your gender, weight, pre-existing conditions, and other factors.
Following these steps can help you avoid or reduce dry skin. If you are still having difficulties after taking such steps, see a dermatologist. They can provide additional advice on how to enjoy the winter without all that itching and flaking.
