Ever what causes those pee shivers? Not even sure what a pee shiver is? Then read on because we explain it all.

• Health: Medical

This is one of the questions that puts you in one of two camps. You either want to know what causes pee shivers or you want to know what a pee shiver is.

A pee shiver is your body shivering just like it does when it's cold, but this happens right at the end of peeing. It seems to happen pretty much only in men, so sorry ladies you're missing out yet again. It's usually a very quick thing, as if your body could product just a single shiver.

Pretty crazy right? If that's not enough, there's even a medical-like name for this which is Post-Micturition Convulsion Syndrome. Insane!

Why does this happen? There appears to be a few theories without anyone truly knowing why.

Theory 1 - Temperature Drop
This one seems pretty logical. Go pee out a large quantity of piping hot wiz and your core body temperature drops suddenly. Your bodies reaction is to shiver because shivering is how your body warms itself up.

Theory 2 - Chemical Stuff
If you love a good technical answer then this theory is for you. Your autonomic nervous system (ANS) is what controls your various involuntary bodily actions (like blinking and other things you don't have to think about). The ANS keeps the bladder relaxed throughout the day but keeps certain bits (the valve leading to the outside world) tensed so that you don't pee yourself. It does this without you thinking about it, hopefully.

This unconscious process uses chemicals like dopamine and epinephrine in your brain. When it's time for a wiz, we voluntarily relax the valve to release urine. That sudden switch from the conscious to unconscious with all of those chemicals running around could cause the shivers.

Theory 3 - Bad Mojo Mumbo Jumbo
I had a nutty woman suggest that the pee shiver is the bad energy (your bad mojo I suppose) leaving your body. Those who are more spiritual may more easily accept this type of theory. Personally, I have a tough time with this one but it didn't help that it was a lunatic that suggested it to me.

So which is correct? Nobody knows for certain. Turns out that this isn't the type of thing that research companies spend millions of dollars finding out. I'm sticking with the sudden temperature drop theory because often the simplest answer is the right one.
