If you’re a male and you have to get up in the middle of the night to urinate, you may want to engage in more activity during the day. Compared to men who were inactive, those who were physically active for one or more hours per week were 13% less likely to have nocturia and 34% less likely to have severe nocturia. Nocturia is a common lower urinary tract symptom in men that can be caused by an enlarged prostate, overproduction of urine, low bladder capacity, and sleep problems. Nocturia becomes more common with age and is believed to occur in more than 50% of men 45 and older.
