Why You Shouldn’t Use the Bathroom “Just in Case”

You’ve done it. You’ve maybe even told your kids to do it before walking out the door. But according to health experts, the precautionary act of going to the bathroom “just in case” might be doing more harm than good.

The term for it is “proactive voiding.”

A recent article in The New York Times dove into the science behind a habit called proactive voiding—that is, going to the bathroom before you actually feel the need. While it may seem harmless, urologists say it could mess with your body’s natural signals if done too often.

Your bladder is a muscle. And just like any other muscle, it adapts to routines. If you consistently go before your bladder is full, it may start telling your brain you need to pee sooner than you really do. And over time, this can condition your body to feel like it’s constantly time for a bathroom break, even when your bladder is only half full or less.

How much pee can my bladder hold?

To put it in perspective, a healthy adult bladder typically holds about two to three cups of urine—closer to two for women and three for men. But even under normal conditioning, we feel the urge to go at just half that volume.

Add habitual “just in case” trips to the mix, and you might find yourself sprinting to the restroom way more often than necessary.

Another reason to not do it: incontinence

Sure, using the bathroom 20 times a day would be annoying in and of itself. But peeing when you don’t need to can also cause some real physical consequences. Namely, you might eventually not be able to hold it.

Trying to pee when there’s not much in there can cause straining, which may weaken your pelvic floor muscles over time. And that, ironically, can lead to even more urinary issues.

What if I’ve already trained by bladder to pee too often?

The good news is if you’ve developed a “go now just in case” reflex, it’s not too late to undo it. Experts say retraining your brain is possible, and cognitive techniques can help.

Think things like simple distractions, deep breathing, and self-talk. (Yes, literally talk to your bladder and say, “I’m the one in control here, not you!”) As one expert put it, it’s not just mind over matter, it’s “mind over bladder.”

TL;DR

In short: go ahead and take that preemptive pee before your next road trip. You’ll probably be fine as long as you don’t make it a daily habit.

But unless you’re dealing with limited bathroom access, or a medical issue, it’s better to wait until you actually have to go.
