"Rinsing off for just 1 minute eliminates most of the filth, perspiration, or anything else on your body," says Chris Wiant, chair of the Water Quality & Health Council. When it comes to bodily functions, 40% of those polled claimed to having peed in a pool as an adult. The other 60% said they'd done it as a child. The number one reason people give for peeing in the pool is "convenience." If you're in a hurry, there's no need to go to the bathroom before jumping into the pool. And since nobody wants to get out of the water, we all know how long 3 minutes can be. The second most common reason given is "no time to spare" - if you've got an appointment coming up or something like that, you may want to make sure you have enough time to get through it without needing to stop what you're doing. Of course, there are other reasons too. If you live by yourself, rinsing off after going to the bathroom is easy enough. But if you have someone else living with you, this might not be such a good idea. They might not appreciate the smell of urine filling the house, nor the fact that it's getting into the pool filter. Also, if you suffer from diabetes or some other medical condition, it's best to avoid peeing in the pool because you don't want to cause any problems with your blood sugar levels.
