Feeling relief when holding in urine for some time is a common experience, and there are a few reasons why it might happen:
Stretch receptors: The bladder has stretch receptors that send signals to your brain when it starts to fill up with urine. When you resist the urge to urinate, these receptors continue to send signals to the brain, which can trigger the release of endorphins. Endorphins are neurotransmitters that act as natural painkillers and mood enhancers, leading to a temporary feeling of pleasure or relief.
Delayed gratification: Holding in urine can create a sense of accomplishment or satisfaction, similar to the feeling of successfully delaying gratification in other situations. This sense of control or willpower may contribute to the positive feeling.
Distraction from discomfort: In some cases, the relief you feel might be more about the distraction from the discomfort of a full bladder than the act of holding it in itself. When you finally relieve yourself, the contrast between the discomfort and the subsequent relief can be quite noticeable and pleasurable.
While holding in urine occasionally is generally harmless, it's essential to remember that regularly delaying bathroom trips can have negative consequences for your urinary system and overall health. When you consistently ignore the urge to urinate, it can lead to urinary tract infections, bladder issues, or in extreme cases, even kidney problems.
It's crucial to listen to your body's signals and respond to the need to urinate in a timely manner. If you find yourself holding in urine frequently or experiencing discomfort or pain while urinating, it's a good idea to consult a healthcare professional for a proper evaluation and advice.
