1. It’s great for the heart
In a recent study conducted at Duke University Medical Center, researchers found that walking briskly for 30 minutes every day lowers your odds of developing metabolic syndrome, a cluster of risk factors linked to higher risks of heart disease, diabetes, and stroke. Roughly 24 million women in the United States have metabolic syndrome. Don’t have time for a daily half-hour walk? Try multitasking: A British study found that active commuting (incorporating walking and cycling into your sedentary commute) is associated with an 11 percent reduction in heart-disease risk, especially among women.

2. It cuts breast-cancer risks
Walking, even for a few hours a week, significantly reduces breast-cancer risk, according to a study published in the Journal of the American Medical Association. The thinking is that walking helps reduce levels of body fat, a source of estrogen. The research looked at 74,000 postmenopausal women between the ages of 50 and 79. Those at a normal weight lowered their risk by 30 percent; those who were overweight, by 10 to 20 percent. Younger women may also gain similar benefits.
3. It helps you sleep
A brisk walk in the afternoon will help you get a better night’s sleep, according to the National Sleep Foundation. Experts say that walking may boost levels of the feel-good hormone serotonin, which relaxes you. Or, the rise in body temperature brought on by walking may signal the brain to lower your temperature later, which promotes sleep. (Avoid a walk two hours before bed—that’s too late to cool down.)
