Four Things You Might Be Doing Wrong in the Bathroom:

If you think you know what you're doing in the bathroom, think again. Here are four things you might be doing wrong.

#1.) Don't Flush With the Lid Up. You might not see it, but it splashes tiny droplets of water all over the place. And that water is filled with germs and bacteria.

#2.) Don't Store Your Toothbrush on the Sink. Germs can still make it to your toothbrush from the shower or the toilet . . . even if you flush with the lid down. So you're better off storing it in the medicine cabinet.

#3.) Don't Drink Water From the Showerhead. The showerhead is a breeding ground for bacteria that can make you sick. And the water itself isn't safe, because bacteria can also grow in your hot water heater.

#4.) Don't Use the Same Contact Lens Case for More Than Three Months. You've probably heard this before, and you still don't do it. But you should throw your case away every three months, because bacteria builds up on the plastic. And it can transfer to your lenses and cause eye infections.
