Before the internet, medical knowledge traveled by jungle gym.<\/p>\n

It came from the kid at recess who could burp the alphabet and told you that gum stays in your stomach for seven years. He said cracking your knuckles will give you arthritis, and that swimming after eating a hot dog will make you cramp and sink like an anchor. No citations, no evidence, just terrifying confidence and a Kool-Aid mustache.<\/p>\n

Adults weren\u2019t much better. Parents, guardians, teachers, camp counselors and older siblings all contributed to the grand public-health curriculum of the 1970s, \u201980s and \u201990s: Going outside with wet hair gives you a cold. Cross your eyes, and they might stay that way forever.<\/p>\n

\u201cThat was just how people learned things about their bodies,\u201d says Dr. Aaron E. Carroll, coauthor of Don\u2019t Swallow Your Gum!: Myths, Half-Truths, and Outright Lies About Your Body and Health. \u201cYou couldn\u2019t Google a claim. You asked your mom, who heard it from her mom, who heard it from a doctor she trusted decades earlier.\u201d<\/p>\n

So we rounded up the most persistent medical myths that circulated through childhood, and asked doctors and scientists what everyone got wrong.<\/p>\n

Wet hair in the winter causes colds<\/p>\n

Apparently, every damp-headed kid was one chilly breeze away from coming down with something. But colds aren\u2019t caused by wet hair, frigid air or your mother\u2019s disapproval. \u201cColds are caused by viruses, not the weather,\u201d says Dr. William Schaffner, professor of preventive medicine and infectious diseases at Vanderbilt University Medical Center in Nashville, Tennessee.<\/p>\n

The confusion, Schaffner says, comes from timing. Respiratory viruses spread heavily in winter, which is why we call them \u201ccolds\u201d in the first place. But damp hair doesn\u2019t make you more likely to encounter a virus or get sick from one.<\/p>\n

We spent our childhoods believing that swallowed gum was basically a nonrefundable deposit in our intestines.<\/p>\n

Cracking your knuckles causes arthritis<\/p>\n

For generations, knuckle-cracking was another step toward hands shaped like tree roots.<\/p>\n

Then came Dr. Donald Unger, who for more than 60 years cracked the knuckles of his left hand at least twice a day while leaving his right hand alone. That added up to at least 36,500 cracks. In 1998, he published the results: X-rays showed no arthritis and no difference between the two hands. His work later won an Ig Nobel Prize for oddball research.<\/p>\n

So what is that satisfying sound? According to Dr. Richard S. Gilbert, a hand and wrist surgeon at Northwell Health in Great Neck, New York, it\u2019s \u201ca mechanical process.\u201d When you stretch a joint, he explains, \u201cthe pressure within the joint decreases,\u201d creating a small vacuum that pulls dissolved nitrogen gas out of the synovial fluid, the lubricant that keeps joints moving smoothly. \u201cTiny bubbles form and then collapse,\u201d he says, producing the familiar pop.<\/p>\n

The important part is that the collapsing bubbles don\u2019t damage the joint or cartilage. \u201cCracking knuckles does not result in arthritis,\u201d Gilbert says.<\/p>\n

Swimming after eating causes cramps and drowning<\/p>\n

This was the sacred pool rule: Eat one hot dog, three chips and half a grape soda, and you were sentenced to an hour on a towel, watching luckier children enjoy their freedom. Because swimming too soon after eating could cause your stomach to cramp so much that you\u2019d sink before the lifeguard finished rotating his whistle.<\/p>\n

Carroll suspects the rule had less to do with physiology than with crowd control. \u201cA lot of these rules started out as practical adult management dressed up in the language of safety,\u201d he says. \u201c\u2018Wait an hour\u2019 is a lot easier to enforce than \u2018I need a break from watching you in the pool.\u2019\u201d<\/p>\n

The danger calculation also favored the myth. \u201cNobody is going to demand a randomized controlled trial when they think a kid\u2019s life is on the line,\u201d Carroll says. If the rule is wrong, the worst outcome is whining. If it\u2019s right, the fear is tragedy. That makes parents enforce it, repeat it and judge anyone who doesn\u2019t.<\/p>\n

However, \u201cThere are no documented cases of drownings caused by swimming after eating,\u201d Carroll says.<\/p>\n","protected":false},"excerpt":{"rendered":"Before the internet, medical knowledge traveled by jungle gym.
