Why Going to the Bathroom “Just in Case” Is a Bad Idea

Preventative peeing too often could be a bad idea in the long run.

Do you constantly use the bathroom before getting in the car, watching a movie, or exercising, even when you don’t feel the urge? Some experts say you might be causing more trouble for yourself.

Your bladder is about 400 to 500 mL—about the size of a can of soda, says Steven A. Kaplan, MD, director of Benign Urologic Diseases and The Men’s Health Program at the Mount Sinai Health System. But if you start going before your bladder is actually full, you might train your bladder to want to empty when it’s only half that, he says. “People sensitize their bladders to go at lower volumes than needed,” says Dr. Kaplan. “It’s hard to get out of that because they’re so used to that.” Don’t miss these other 11 things you never knew about peeing.

The problem isn’t so much that you physically can’t hold your pee, but that you’ve convinced yourself you won’t be able to, says Sandip Vasavada, MD, urologist with Cleveland Clinic. Some people prevent leakage by using the bathroom before, say, a workout class. After all, nothing can leak from an empty bladder. But doing that gets you used to peeing at the very first urge—or sooner. “They go into the habitual pattern of going all the time,” says Dr. Vasavada. Empty your bladder too soon too often, and you’ll forget just how long you can hold it. Plus, holding your pee could make you smarter.

If you are prone to leaking, don’t be afraid of some preventative peeing before a long stretch of time, like a road trip, says Dr. Vasavada. Going “just in case” every now and then likely won’t cause an issue, unless it’s a daily habit. In fact, preventional peeing is usually a reaction to an overactive bladder, rather than the cause, says Dr. Vasvada. Learn about other medical reasons you need to pee all the time.

But if constant bathroom trips frustrate you, try training yourself out of it, says Benjamin Brucker, MD, uro-gynecologist and assistant professor of Urology and OBGYN at NYU Langone Medical Center. “Don’t give into every small whim of needing to void,” he says. He also recommends keeping a log of your bathroom stops to figure out how often you go and doing kegels to help you hold it.
