With temperatures plummeting throughout most of the U.S., I continue to be bombarded with questions surrounding what kind of impact this harsh weather has on the skin.

Surprisingly, many ask if colder temperatures have medicinal or anti-aging benefits – but to date, there are no known anti-aging benefits resulting from very cold temperatures. In fact, low temperatures can make skin dry, raw and irritated. Exposing your skin to cold temperatures (such as winter weather and wind) can promote and contribute to aging.

So, how should you protect your skin during the winter months?

I‘ve always recommended patients use a thicker, richer moisturizer to create a barrier from the elements. I also suggest that patients use moisturizers indoors during the winter months because heated rooms can cause skin to become dry and dehydrated. Using a humidifier is also a good idea.

With that said, it’s important to avoid both extremely hot and extremely cold temperatures due to the negative impact on skin.

But the cold can also be very healing in specific settings. If you are fighting puffiness under or around your eyes, applying a cool compress has soothing effects and can reduce inflammation. Cool compresses may also reduce swelling associated with redness in the eye area.

I also recommend the application of cold compresses for the immediate treatment of a thermal or chemical burn. I recommend putting the affected area in cold water (but not ice water) for up to 30 minutes immediately after the burn. This type of cold treatment has been shown to reduce the total area of the burn as well as its depth.

Many of us don’t realize that we spend about one-third of each day at home (except less for workaholics) and during this time we are exposed to potential indoor allergens. 

The most common causes of indoor or year-round allergies include house dust, dust mites, pet dander, feather bedding, mold spores and cockroach allergens. During the wintertime, indoor air is rather dry and we may feel it with parched, chapped lips and dry skin.  Many people prefer to use an indoor humidifier to moisturize the air for greater comfort as well as to soothe dry nasal and sinus passages.

The number one indoor allergen for most people with allergies is the “house dust mite” (a potent indoor allergen within dust).  These spider-like critters (fortunately you cannot see them without a microscope) love to inhabit warm, cozy places like pillows, mattresses, box springs and duvet covers in the bedroom.  You may have as many as two million dust mites in your bedding!  So what do they need to survive? Moisture! As we moisturize the indoor air with a humidifier, we are actually mobilizing them for a real party as they absorb water from the nearby environment.

If you happen to use a humidifier, it is essential to monitor the level of indoor humidity with a hygrometer (costs about $10-15).  You want to avoid over doing it and keep the level of humidity indoors below 50 percent (shoot for range of 30-50percent).  Follow the manufacturer’s instructions for cleaning a humidifier and refill with fresh water daily.
