Women have another reason to exercise: It may help prevent kidney stones. You don’t have to break a sweat or be a super athlete, either. Even walking for a couple hours a week can cut the risk of developing this painful and common problem by about one-third, a large study found.
‘‘Every little bit makes a difference’’ and the intensity doesn’t matter — just getting a minimum amount of exercise does, said Dr. Mathew Sorensen of the University of Washington School of Medicine in Seattle.
About 9 percent of people will get a kidney stone sometime in their life. The problem is a little more common in men, but incidence has risen 70 percent during the past 15 years, most rapidly among women.
