When it comes to bodily functions, one of the most frequently asked questions is, “how clean is urine?” Urine is the liquid waste produced by the kidneys, and many wonder just how clean it is, especially in terms of its potential uses and health implications.
Urine is primarily made up of water, but it also contains various dissolved substances such as salts, toxins, and waste products the body needs to get rid of.
How clean is urine when it comes to health, hygiene, and even its potential uses in the medical field? Let’s take a closer look.
What Is Urine Made Of?
According to Physiological Reviews, urine is produced by the kidneys as they filter blood, removing excess water, waste products, and toxins. Typically, urine is about 95% water, but the other 5% is made up of substances such as:
- Water – About 95% of it. That part is clean.
- Urea & Creatinine – Waste products from your kidneys filtering your blood.
- Electrolytes – Sodium, potassium, chloride—some of the same stuff found in sports drinks.
- Toxins & Metabolic Byproducts – Everything your body wants to get rid of, including medications, excess vitamins, and whatever’s left after breaking down food, alcohol, or drugs.

So, while urine isn’t the festering swamp of disease some might think, it’s also not some magical, pure liquid. It’s the stuff your body decided it doesn’t need anymore.
How Clean Is Urine in Terms of Bacteria?
According to Journal of the American Society of Nephrology, urine is usually sterile when it’s produced by the kidneys. This means that, in a healthy individual, urine that has just left the body is free of bacteria.
However, as it travels through the urinary tract, it can become contaminated by bacteria, particularly if hygiene is poor or if there’s an existing infection.

“Urine is sterile when produced in the kidneys, but it can quickly pick up bacteria as it passes through the urinary tract.”
In cases where a person suffers from a urinary tract infection (UTI), the urine may contain high levels of bacteria, which can be detected through a urine test.
This is why it’s essential to maintain good personal hygiene, especially when urinating, to prevent bacterial contamination.

How Clean Is Urine for Medical Purposes?
Urine plays a crucial role in diagnosing various medical conditions. Medical professionals use urine tests to monitor a person’s health. From testing kidney function to detecting the presence of drugs, urine is an essential part of medical diagnostics.
However, urine isn’t always “clean” in the sense that it can harbor toxins, drugs, or waste products that need to be eliminated.

Here are some common uses of urine in medical diagnostics:
- Urinalysis: A test used to detect signs of infections, kidney disease, diabetes, and other health conditions.
- Pregnancy tests: Urine is used in at-home tests to detect the presence of the hormone hCG.
- Drug testing: Urine can be used to test for the presence of illegal substances or medications.
Although urine is sterile in the bladder, it’s still crucial to ensure the cleanliness of the container or sample used for testing.

How Clean Is Urine for Reuse?
There’s been interest in urine reuse, especially in survival situations or certain alternative medicine circles.
However, the idea that urine can be used as a drinkable resource is a myth and can be dangerous. While urine is sterile when it leaves the kidneys, it’s still full of waste products, toxins, and other substances your body needs to eliminate.

For example, if a person is dehydrated or has a high concentration of waste in their urine, drinking it could put unnecessary strain on the kidneys and even lead to further dehydration.
In medical situations, it’s always better to rely on clean water and proper hydration rather than urine.
So, Is It Clean?
Urine is relatively clean compared to, say, raw sewage, but it’s not something you’d want to treat as pure or sterile. It’s a waste product, not a health tonic.

But here’s what I have learned so far during my life journey: The body is an incredible, self-sustaining system. It works day and night, filtering, cleaning, balancing—even when we barely give it the care it deserves. I’ve seen my own body go from breaking down to healing itself, and if there’s one thing I trust, it’s this:
Give your body what it needs—water, nutrients, rest—not what it’s already thrown away.
If you want to take care of yourself, focus on what goes in, not what comes out. Because your body already knows what to do with the rest.

How to Keep Your Urine Clean
To maintain clean urine, it’s essential to stay hydrated, practice good hygiene, and pay attention to your body’s needs. Here are some simple tips to help ensure that your urine stays as clean as possible:
1. Stay Hydrated
Drinking enough water helps your kidneys flush out waste products, keeping your urine clean and clear.
Proper hydration is key to maintaining clean urine. When you’re well-hydrated, your kidneys can filter waste more effectively, and your urine will be diluted, making it lighter in color and less concentrated.

Maintaining good hygiene habits is crucial to keeping your urinary system clean. Make sure to wipe from front to back after using the toilet to prevent bacteria from entering the urethra and causing infections.
3. Avoid Excessive Use of Chemicals and Medications

4. Monitor for Signs of Infection
UTIs and other urinary issues can cause discomfort and make your urine less clean. Seek medical attention if you notice any abnormalities.
Pay attention to any changes in your urine’s color, odor, or frequency. If you experience pain, burning sensations, or cloudy urine, it may indicate an infection, and it’s important to seek medical advice.
