Find out how many miles a week you should log to reap the benefits.

Your heart isn’t the only organ that can benefit from regular running: The more fit and active you are, the less likely you are to develop glaucoma, a serious eye disease that can damage your optic nerve and even lead to blindness, new research set to be published in Medicine & Science in Sports & Exercise finds.

In the study, researchers analyzed data from more than 9,500 people between ages 40 and 81 enrolled in a long-term study at the famous Cooper Clinic in Dallas. The researchers compared the subjects’ aerobic fitness (measured by treadmill tests) and weekly amount of exercise (reported by the subjects) to how many of them developed incident glaucoma during a nearly six-year follow-up period. The researchers specifically looked at incident glaucoma, the more common form of the condition, rather than traumatic glaucoma, which is caused by direct injury to the eye.
