To Pee Or Not To Pee

Is it “strengthening” to hold, or are we doing ourselves harm if we do? Dr. Heba Shaheed explains in this short video:

A flood of reasons not to hold

Humans should urinate 4–6 times daily, but for many people, the demands of modern life often lead to delaying urination, raising questions about its effects on the body.

So first, let’s look at how it all works: the bladder is part of the urinary system, which includes the kidneys, ureters, urethra, and sphincters. Urine is produced by the kidneys and transported via the ureters into the bladder, a hollow organ with a muscular wall. This muscle (called the detrusor) allows the bladder to inflate as it fills with urine (bearing in mind, the main job of any muscle is to be able to stretch and contract).

As the bladder fills, stretch receptors in that muscle signal fullness to the spinal cord. This triggers the micturition reflex, causing the detrusor to contract and the internal urethral sphincter to open involuntarily. Voluntary control over the external urethral sphincter allows a person to delay or release urine as needed.

So, at what point is it best to go forth and pee?

For most people, bladder fullness is first noticeable at around 150-200ml, with discomfort occurring at 400-500ml (that’s about two cups*). Although the bladder can stretch to hold up to a liter, exceeding this capacity can cause it to rupture, a rare but serious condition requiring surgical intervention.

*note, however, that this doesn’t necessarily mean that drinking two cups will result in two cups being in your bladder; that’s not how hydration works. Unless you are already perfectly hydrated, most if not all of the water will be absorbed into the rest of your body where it is needed. Your bladder gets filled when your body has waste products to dispose of that way, and/or is overhydrated (though overhydration is not very common).

Habitually holding urine and/or urinating too quickly (note: not “too soon”, but literally, “too quickly”, we’re talking about the velocity at which it exits the body) can weaken pelvic floor muscles over time. This can lead to bladder pain, urgency, incontinence, and/or a damaged pelvic floor.

In short: while the body’s systems are equipped to handle occasional delays, holding it regularly is not advisable. For the good of your long-term urinary health, it’s best to avoid straining the system and go whenever you feel the urge.
