Is It Dangerous to Wake Up a Sleepwalker? 50 Health Myths You Should Stop Believing

"Newsweek" took the time to comb through some of the most popular health myths out there and debunk them. Here are 50 of the most common myths.Newsweek
“Alcohol warms you up.” Not true. In fact, alcohol moves warm blood closer to the skin, a false sense of warmth that’s actually making you lose body heat.Pixaby

Health myths are like chips—they're so delicious that you just can't stop at one. Think about all the myths you have just accepted over the years: An apple a day keeps the doctor away, the five-second food rule, or exercise is bad for you and you should stop it immediately….OK, that last one isn’t a myth, just wishful thinking and patently false.

But that’s just it: Oftentimes the myths that we’ve come to accept are just wishful thinking. How great would it be if apples were a miracle food and could legitimately cure any ailment to the point that you would never need to visit a doctor ever again? Or, more recently, people are going on gluten-free diets because it is thought that carbs make you fat.

“While it is becoming more popular to blame carbohydrates as the cause of obesity, people don't realize that de novo lipogenesis (DNL; which converts sugars into fat) tends to be inefficient in human bodies,” Dr. Spencer Nadolsky told Lifehacker.com. “For carbs to make one fat, they would need to work in concert with a poor diet and lack of exercise which makes those latter two more readily blamed.”

Also, people with actual gluten sensitivities want you to stop buying all their food just because you want to be skinny. They’re hungry, too, thank you.

Then there are those myths that are wrong because they were initially intended to scare or distract you, like alcohol killing your brain cells, vaccinating children increases their chances of becoming autistic or going outside in cold air with wet hair will increase your chances of becoming sick.

So what are these myths, and are any of them based in truth? Newsweek took the time to comb through some of the most popular health myths out there and debunk them. Here are 50 of the most common myths. Prepare for your mind to be blown. You’re welcome.

“Don’t wake a sleepwalker. Something tragic could happen.” Wrong. Sleepwalkers are often in such a deep state of sleep, they won’t even notice you. The worst that could happen is that the sleepwalker will wake very distressed. Best thing to do, just gently guide them back to bed. Freestocks
“Carrots are good for vision.” Sure, they’re healthy and offer Vitamin A, which benefits vision. But you’d have to eat a semi truck full of carrots to see any real results. Pixaby
“Alcohol kills your brain cells.” Drinking doesn’t instantaneously kill your neurons, but can, over time, have a serious impact on the brain. Burst
“Wait an hour after eating before swimming.” Wrong. No evidence supports this lasting myth. Cramps do happen while swimming, but they aren’t caused by what’s in your stomach. Juan Salamanca
“Deodorant causes cancer.” Even though it does seem like everything causes cancer these days, no significant evidence or research supports this myth. Godisable Jacob
“Wet hair outside might make you sick.” Wrong. Cold air doesn’t make you sick, the flu virus does. Leah Kelley
“Juice is better than soda.” Ehhhhh, not really. Juice often has a ton of sugar. You would be better off eating an actual piece of fruit.Pixaby
“Bottled water safer than tap water.” In some areas, sure, filtered water might be better, but consider this: Over 50 percent of bottled water is basically just tap water, Natural Resources Defense Council reports. Steve Johnson
“No pain, no gain.” Well, if you equate pain with laziness, then yeah, this is true. But if you’re actually in pain, don’t work out. It could make things worse. Pixaby
“We only use 10 percent of our brains.” So false. We use almost every part of our brain. Even simple tasks require various parts of our brains working together to accomplish the task, like drinking water, walking...basically living. Neo
“Burned? Get some butter or ice on it.” Wrong—so, so wrong. Butter will make the burn worse because it spreads heat. Ice only damages the cells needed for your body to heal from the burn. Pixaby
“Flu shot just gives you the flu.” No, you cannot get the flu from the flu shot. The only side effects are temporary soreness or redness in the area where the shot was administered. Rex Pickar
