If urine is sterile, why do we have to wash our hands after we use the bathroom?

Answer 1

Urine is mostly sterile, and definitely safe to drink.

Most people forget that urine is mostly water. Water is the filter of the human body. Waste that our cells produce, collectively known as urea, ends up in our bloodstream. Our kidneys remove the urea, along with excess water, and the result is urine. Now, you ask if it's sterile - and yes, for the most part it is - but as urine leaves the body - that's where it picks up the other bacteria that exists outside the body, on the toilet stool, etc.

It is necessary to wash our hands often - just to remove the bacteria from it. The hands often pick up much of the bacteria that we attribute to colds, flu, and other things. To be honest - we don't wash our hands nearly enough.
