Sleeping with the enemy: When's the last time you cleaned your pillow?

Here's an important hygiene issue that many of us don't think about too often: our pillows. If you've had the same pillow for over two years, who knows what could be lurking on it. Mold, mites and a plethora of germs can all be lurking where you rest your head at night -- yuck!

Experts recommend that you buy new pillows every 2 years, but if that's not possibly, pillow protectors can help keep out the bad stuff. And according to Fitsugar, you can 'clean' your pillows every few weeks by putting them in the dryer on high heat for 20-minutes or so.
