It's been proven that tap water is almost always safe to drink, but there is one thing you can do to make sure wherever you are, it'll be even safer. If you're filling a glass from the faucet, do this: Let the water run for at least 15 seconds. This is especially important if the faucet hasn't been used in the last six hours or if you're unsure when it was last turned on. This will help flush out any metals, like lead, that may have seeped into the water that was sitting in the pipes. If you want to avoid this, fill a pitcher, add a lid and keep it in the fridge.

It sounds like the greenest idea: If you're going to boil a bag of pasta, why not fill the pot with the hottest possible tap water you have so it takes less time (and energy) to bring it to a boil? But the reality is you should never do this, because there are health risks. In most homes, hot water systems use tanks and boilers that contain metal parts, and over time, the metal corrodes and contaminates the water. Boiling water doesn't make these metals -- including lead -- go away, and they can contaminate whatever you're cooking. Always use cold water when you need to bring any water to a boil.

If you throw pillows onto the floor from your bed before drifting off, it might be time to think about keeping only the pillows you actually use on the bed. Tossing decorative pillows onto the floor each night and then placing them back on your bed when you make it in the morning can lead to a dirtier sleep. The pillows pick up dirt, germs and other allergens from the floor and can deposit that gunk on your freshly made bed.
