If you’ve ever held a cup of urine after providing a sample in it for your doctor, you will have noticed that the cup was warm.

Or, if your urine has ever streamed down a leg, you’ll recall that it had a warm feel.

• Your skin should feel pleasantly warm.

• If you’ve ever sat in a seat that someone had been sitting in for a while, it’ll be warm.

• In short, the human body is warm, with its normal temperature around 98.6 degrees.

So why wouldn’t something that comes out from inside the body be warm – such as urine? After all, we are warm blooded.

But what about urine that seems more hot than warm?

“Warm or hot urine is normal, especially if a person is cold,” says J. Mark Anderson, MD, DABFM, of Executive Medicine of Texas and who is board certified in family medicine.

Dr. Anderson explains, “Often, when patients have a fever, they may notice their urine is also warmer than usual. That’s because the urine will reflect the core temperature of the body.

“However, if a person experiences burning, it may be a sign of infection and should never be ignored.”

When Urinating Has a Burning Sensation

If it “burns” when you urinate, this isn’t because the urine is extra hot. It’s because the bacteria from a urinary tract infection have irritated the delicate lining of your urinary tract.

The reason this symptom should never be ignored is because a UTI that goes untreated can lead to kidney damage.

Another cause of burning, which has nothing to do with any changes in the urine itself, is the presence of anal fissures.

When normal urine makes contact with these irritations in the skin, the chemical makeup of the urine causes a burning or stinging sensation.

“If urine feels hot and there is blood present, seek medical attention immediately,” says Dr. Anderson. This most likely means a UTI that has progressed.
