Healing the skin and keeping it healthy are important to prevent further damage and enhance quality of life. Developing and sticking with a daily skin care routine is critical to preventing flares. Tanning also is responsible for chronic sun damage including wrinkles, leathery skin texture, and mottling or “age spots” (really “sun” spots).

A warm up generally consists of a gradual increase in intensity in physical activity. For example, before running or playing an intense sport one might slowly jog to warm muscles and increase heart rate.

"If U.S. citizens put in 30 minutes of aerobic activity five times a week it would cut the amount of chronic diseases and health costs by almost half. That's how powerful physical fitness is," says Pamela Peeke, M.D., M.P.H., assistant clinical professor of medicine .

Studies continue to show that it is never too late to start exercising. At any age, even small improvements in physical fitness and activity (such as walking regularly) can prolong life and independent living. Still, about half of Americans over 60 describe themselves as sedentary.

The sweat experts divide exercise into three general categories:

1. Aerobic (also called endurance).
2. Strength (also called resistance).
3. Flexibility(Also called stretching

A balanced program should include all three. (Speed training is also a major category, but is generally practiced only by competitive athletes.)

Exercising helps people reduce their weight, maintain weight loss, and fight obesity. Research has shown that women who regularly exercise but do not change their diet can lose significantly more weight than less active women.
