Hot Tubs are a luxury many like to enjoy after a long day at work or while vacationing. But before you jump in to another one, you might want to think twice thanks to science.

A new study finds that the high levels of heat in the hot tub actually prevent the chemicals in the water from actually killing the bacteria they are supposed to. Which in turn means you might pick up some rather nasty germs or even bugs.

The Centers for Disease Control of Prevention and University of Arizona recently conducted a study to look at what exactly is in a hot tub at any given time; it's rather nasty.

One germ that remains even after the heat and chemical treatments is Pseudomonas aeruginosa which can cause Pseudomonas folliculitis, or commonly known as 'hot tub rash.' The longer you sit in a hot tub, the longer your skin is exposed to this germ and it's potential effects. It's most common symptoms are pus-filled blisters, itchy skin, and a bumpy rash.

Don't think that was bad enough? How about this:

The average bather has about a tenth of a gram of feces in his gluteal fold, which is a nice way of saying butt crack, -  Charles Gerba, Ph.D from the University of Arizona

Yep, you're swimming around in other peoples' poop. If you have five people in a hot tob Gerba continues by saying:

You have a tablespoon of poop in the hot tub.

And that's not all! What if someone decides they need to pee and do it in the hot tub? Well when urine mixes with the chlorine is can create what is called chloramine. That can cause red, itchy eyes. One way to tell if someone has gone 'number one' in the hot tub, the chlorine smell. Chloramine actually can cause that smell.

It's really important to not use the hot tub as a restroom. - Michele Hlavsa, CDC

And now that we've disgusted you, happy hot tubbing!
