Water may be the healthiest beverage (not to mention necessary to life) but you can definitely get too much of a good thing, says Neal Schultz, MD, NYC dermatologist, founder of DermTv.com and creator of BeautyRx. At best, overhydrating will have you peeing every 30 minutes and at worst it can kill you. There is a “right way” to drink enough water and it comes down to trusting yourself. Your body is great at knowing how much water it needs, so forget drinking eight cups a day or half your body weight in ounces or any other prescribed amount. “You should drink to your thirst, not to meet an arbitrary number,” he advises. Be sure not to fall for any of these 55 rampant health myths that need to die.
Getting a base tan can prevent sunburnsJacob Lund/Shutterstock
Even though skin cancer is the leading cause of cancer deaths in adults under 40, many people still hold the faulty belief that getting a “base tan” will protect them from sunburns and cancer, make them look youthful, or clear up acne. Not so, says Jennifer Caudle, DO, board-certified family physician and assistant professor at Rowan University. There is no such thing as a “little” tan and all tanning increases your risk of cancer. Nor will it help your skin, in fact, sun damage is the primary cause of wrinkles, she adds.
