According to the American Cancer Society, the number of cases of melanoma-the most dangerous form of skin cancer-tripled in the United States between 1980 and 2003. Skin functions as one of the human body's first lines of defense against bacterial, viral, and fungal infections that can cause disease. The primary cause of skin cancer is excessive exposure to the sun's ultraviolet radiation. Skin cancer is cumulative and research indicates that it can take 20, 30, or 40 years to develop. Skin cancer is a known threat to our health, but it is a threat we can protect against.

Dermatologists recommend avoiding direct exposure to the sun during the hours between 10 a.m. and 4 p.m. whenever possible because that is when ultraviolet radiation is most intense. If outdoor activity is necessary during those times, apply a protective sunscreen cream or lotion on a daily basis. Try to use a sunscreen that has a sun protection factor (SPF) of at least 15, even on cloudy days because ultra-violet radiation penetrates through clouds.

Dry, itchy skin is another very common problem that can be avoided. According to the Mayo Clinic, the most common causes of dry, itchy skin are harsh soaps and detergents, antibacterial soaps, deodorants, frequent hot baths or showers, and central heating and air conditioning. One good idea is to use a mild moisturizing body cleanser instead of soap in the bath or shower. It is also very beneficial to apply an herbal moisturizing lotion after bathing or showering.
