If you think you don't have a single bad habit, check out this list from "Prevention" magazine of four "healthy" habits that aren't actually that good for you.

  • You Brush Your Teeth Right After You Finish Eating.  You've probably heard that you shouldn't brush right after you drink SODA, because soda softens your enamel, which can actually be brushed away.

    --But the same goes for ANYTHING that's highly acidic . . . including things like citrus fruit, tomatoes, and Gatorade.  So if you have anything like that, you should wait at least 30 to 60 minutes before you brush.

  • You Come Home From Work and Immediately Get Your Chores Out of the Way.  If your parents made you do your homework right after school, you might think it's the way to go.  Because it does SEEM like a good habit --The problem is, you don't give yourself time to unwind, so your body keeps pumping out the stress hormone cortisol.  And research shows that higher levels of cortisol lead to more health issues in the long run. --So it's best to at least give yourself 20 or 30 minutes to unwind before you jump into something like doing taxes or cleaning the living room.
  • You Wash Your Pillowcases Once a Week.  That's better than most people, but washing JUST your pillowcases won't necessarily protect you from dust mites . . . which about 10% of people are allergic to.

    --To really protect yourself, you have to wash the actual PILLOWS at least once a month in hot water . . . which most people NEVER do.

  • "Hovering" When You're Using a Public Restroom.  This one's for women who don't want to actually touch the seat with their skin.  So they kind of stand in a squatting position.

    --The reason it's bad is because it causes the pelvic muscles to contract, which prevents you from fully emptying your bladder.  And when you don't do that, you're more likely to get a urinary tract infection.

    --So the best way to handle it is to use those paper seat liners.
