Myth: "Eleven or 12 hours of sleep a night will do the trick."
Heather Graham recently told "People" that she needs 11 to 12 hours of sleep every night to look her best. While most doctors agree that a good night's sleep is necessary for your health, there's no "more is always better" rule. "Everyone needs different amounts of sleep," says Lipman. "Some people need six hours, some people need eight hours -- 12 hours is a little much. Usually between six and nine is right." A study conducted by the Sleep, Health, and Society program at the University of Warwick -- which analyzed data on 1.5 million people -- confirmed that both too little and too much sleep can be harmful, and even lead to premature death.
Celebrities appear to have flawless skin and perfect bodies. And although most of them work unbelievably hard to look that way, they often credit the latest miracle serum or supplement instead of 'fessing up to pricey spa treatments and hours logged at the gym.
While we know these A-listers have armies of dermatologists, trainers, and stylists working behind the scenes, we want to believe that it's easy to look as good as they do. (If there were a pill that could give you Scarlett Johansson's skin or Gisele's hair -- no matter how big of a skeptic you are -- wouldn't you take it?)
Which is why we end up dishing out money on celeb-endorsed products or starving ourselves on crazy fad diets -- only to find out that we've been duped by another celebrity beauty lie.
We turned to experts to help dispel some of the myths celebrities have us believing -- from the ones that we know are far-fetched (like detoxing with leeches) to the ones that seem like they could work (juice fasts, anyone?). Read on to see which myths are totally busted.
