One important attraction of walking is its long-lasting appeal. Whereas jogging and aerobic dancing can pall quickly, walking provides a popular activity that seems to endure. Fitness foundations estimate that 35 million adult Americans walk for exercise every day, with at least 15 million walking two or three times a week. Among the most regular walkers are those 65 years and older—evidence that walking is an exercise that lasts.

In addition to its many physical benefits, walking, like other physical activities, has a comforting effect on the psyche. Walking can help you to think more clearly and feel more relaxed. It also can be a sociable activity. An early morning walk around the neighborhood provides an opportunity to chat with friends or simply admire the  flowers. Or because it does not require a team or even a partner, walking is something you can do on your own time, by yourself, whenever the mood strikes.

Easily affordable, all you need to start walking is enthusiasm and a pair of comfortable and sturdy low-heeled shoes. Dr.ChristineL. Wells recommends an Oxford-style shoe with ties for better foot support; she does not recommend sneakers or other “cheapies”. If you plan to walk regularly, you might want to invest in a pair of so-called walking shoes. If so, expect to spend at least $35.

For walking during the hotter months, early morning or evening hours are best. Clothes should fit loosely and be lightweight and light-colored. Elderly walkers should consider wearing long sleeves, and all Arizonans need to be particularly concerned about skin cancer. Dr. Wells suggests wearing sunscreen as well as a side-brimmed hat to protect your eyes, ears, nose and back of the neck.

Walkers also should drink an adequate amount of water. Wells advises drinking an 8-ounce glass of water before you start out, and more when you return. “If you walk four miles or more a day in Arizona, I also recommend that you carry a water bottle,” she says. “ And water  is just fine; you don’t need those fluid-replacement or electrolyte drinks.”
