The Unspoken Shower Guide: Pool Hygiene and… Other Bathroom Habits Explained

The shower is a private sanctuary. It’s a place where we start our day, wash away our stress, and… ask Google the questions we’d be too embarrassed to ask another human. From public pool etiquette to strange bodily urges, the shower is central to many of life’s most confusing hygiene questions.

Consider this your definitive, judgment-free guide. We’re going to dive into the science to answer these common but unspoken questions. We’ll start with public pool hygiene and then move into the privacy of your own bathroom to tackle an even more sensitive topic. Let’s get started.


Part 1: The Pool Shower Protocol

If you’ve ever been to a public pool, you’ve seen the signs: “Shower Before Entering Pool.” Many of us walk right past them, thinking, “I’m not dirty, why bother?” But I’m here to tell you, as a matter of public health and chemistry, that pre- and post-pool showers are non-negotiable.

Why You MUST Shower *Before* You Swim

The pre-swim shower isn’t really about getting you clean—it’s about protecting the pool’s chemistry and everyone in it. The primary reason is to rinse off the invisible layer of sweat, body oils, deodorant, lotion, and traces of urine that everyone has on their skin.

The Science of Chloramines: When the substances on your skin (which are nitrogen-based) mix with the pool’s chlorine, they create a chemical reaction. The byproduct of this reaction is a class of compounds called **chloramines**. It’s the chloramines, not the chlorine itself, that cause that stereotypical “pool smell,” make your eyes red and itchy, and can irritate your skin and respiratory system. Even worse, chloramines are less effective at disinfecting, meaning more germs can survive in the water.

A quick, 60-second rinse is all it takes to remove most of these compounds from your skin. By doing so, you’re not just being courteous; you’re actively helping to keep the pool cleaner, safer, and more pleasant for yourself and every other swimmer.

Why You MUST Shower *After* You Swim

The post-swim shower is all about protecting your own body. While you were swimming, your skin and hair were soaking in a chemical cocktail of chlorine, chloramines, and whatever bacteria managed to survive in the water.

  • Skin Health: Chlorine is excellent at its job, but it doesn’t distinguish between bad bacteria and your skin’s natural, protective oils. It strips these oils away, leaving your skin dry, itchy, and vulnerable to irritation or “pool rash.”
  • Hair Health: Chlorine is famously damaging to hair. It can make hair brittle, dry, and for those with lighter hair, cause that dreaded greenish tint. A thorough wash is the only way to get these chemicals out.

A proper post-swim shower, using soap and shampoo, removes these harmful residues, rehydrates your skin and hair, and ensures you leave the pool feeling refreshed, not itchy.

Essential Gear for the Serious Swimmer

To combat the effects of chlorine, using products specifically designed for swimmers makes a world of difference.

Part 2: The Physiology of the Shower

Now, let’s step from the public pool into the privacy of your home bathroom. We’re going to address a set of questions that are Googled with surprising frequency, and we’re going to do it with straightforward science.

Why Does Showering Make Me Have to Poop? The Science Explained

If you’ve ever hopped in the shower only to feel a sudden, urgent need to have a bowel movement, you are not alone. This is not a weird quirk; it’s a completely normal physiological response. It all comes down to your nervous system.

The “Rest and Digest” System: Your body has an Autonomic Nervous System that controls involuntary actions. It’s split into two parts: the “fight or flight” system and the **Parasympathetic Nervous System (PNS)**, also known as the “rest and digest” system. The PNS is activated when you are relaxed. A warm shower is one of the most relaxing things you can do. The heat, the sound of the water, and the quiet solitude all send signals to your brain to activate the PNS. When the PNS is active, it increases **gut motility**—the muscular contractions of your intestines that move waste along. This stimulation is what creates that sudden urge.

Think about it: the same thing often happens after a warm cup of coffee or a large, relaxing meal. It’s the same “rest and digest” system being triggered. So, if this happens to you, know that it’s simply a sign that your body is relaxed and your digestive system is functioning as it should.

So, Is It Normal to Poop in the Shower?

Let’s be very clear here. While the **urge** to poop in the shower is perfectly normal, **acting on that urge** is a different story. In terms of social norms and modern hygiene standards, the answer is no, it’s not considered normal or acceptable behavior. The toilet is designed for this specific purpose for very good reasons.

What Happens If You Poop in the Shower? The Hygienic Reality

This isn’t just about it being “gross.” There are legitimate health and plumbing reasons why this is a bad idea.

  • The Health Risk: Human feces contain a host of bacteria, including pathogens like E. coli and Salmonella. While hot water and soap will wash some of it away, you risk contaminating the shower floor, the drain, your feet, your washcloth, and everything else in the enclosure. This creates an unhygienic environment and a risk of spreading bacteria.
  • The Plumbing Problem: Household shower drains and pipes are designed to handle water, soap, and hair. They are not designed to handle solid waste. Forcing solid matter down the drain (a practice sometimes crudely called “waffle stomping”) is a recipe for a serious and expensive clog.

In short, the toilet is the only safe and hygienic place for a bowel movement.

Better Hygiene Solutions

If the urge is a frequent issue, consider upgrading your bathroom hygiene to address it at the source. A clean shower is also paramount.
