Nocturia increases as men age. It’s often due to an enlarged prostate (also known as benign prostatic hyperplasia or BPH). Other causes of nocturia include overproduction of urine, low bladder capacity and sleep apnea.

Researchers analyzed data from a large, ongoing trial called the Prostate, Lung, Colorectal and Ovarian Screening Trial. They analyzed 28,404 men, who had BPH outcomes before enrolling in the study and, 4,710 men who developed BPH after the trial began.

Men who were physically active one or more hours per week were 13 percent less likely to experience nocturia and 34 percent less likely to report severe nocturia than men who had no physical activity,
