Misinformation is kind of like glitter: once it's thrown out there, it's pretty much impossible to retrieve.
Due to misunderstandings and dramatizations in movies, facts get taken out of context and contorted in many different ways. While some of these myths are harmless (though annoying), others can actually pose a risk to a person's health.
Alltime10s has made a new video highlighting 10 medical myths that have been masquerading as facts, but the time has come to put them to rest for good.
Check out the myths here:
10. A shot of adrenaline straight to the heart can revive a dying person.
Trying to jab a syringe straight into someone's heart isn't remotely a good idea. Not only is it bad for the heart to get stabbed all willy-nilly, there is a dire risk of puncturing a lung or even sticking it into a rib, which is fairly horrifying to think about.
9. Humans only use 10 percent of the brain.
This one gets repeated fairly often, but there's absolutely no truth to it. While humans may not use their entire brain for every action, all areas of the brain are used over the course of a day.
8. Eating at night contributes to weight gain.
Eating a lot at night can contribute to weight gain, only because it typically results in overeating having more calories in than out by the end of the day. Ultimately, the total number of calories per day affects weight gain more than when they're eaten.
7. Cold weather causes the cold and flu.
The contagious nature of viruses that cause the cold and flu aren't dependent on the temperature outside, though there is evidence humidity plays a role. However, more people are stuck indoors when the weather is cold, causing more human interaction and potential for spreading germs.
6. Vitamin supplements are beneficial.
Despite being a $90 billion industry, vitamin and supplements aren't really as wholesome as they would like to appear. Supplements aren't regulated like pharmaceuticals and it's fairly common for the quantity of the active ingredient to be different than what is advertised on the bottle. Aside from that, studies have shown most healthy people don't need to take additional vitamins anyway, making it a waste.
5. Sugar makes kids hyper.
Sugar and hyperactivity in children is a matter of correlation, not causation. Hyperactivity at birthday parties and holidays is typically attributed to cake and candy, but it has more to do with the kid being excited for a special day and getting to eat treats, rather than the treats themselves.
4. Adults should drink 8 glasses of water per day.
Though it has long been proclaimed that adults should drink 64 ounces of water per day, many people fail to realize that a lot of this comes from food. Dehydration is a problem for some people, but there are also dangers that can come from overindulging in H2O.
3. Cracking knuckles causes arthritis.
Cracking knuckles, and the oh-so-relieving feeling that accompanies it, does not at all lead to the onset of arthritis.
2. 'Hair of the dog' is good for a hangover
Bloody Marys and Mimosas are pretty standard fare for the morning after having too much to drink, but there isn't any evidence that drinking more alcohol will physically improve a hangover. Though it is possible that the alcohol could dull the pain and make the person feel better about feeling crappy.
1. Swallowed gum takes 7 years to pass through the digestive system.
Though the gum base is made out of some pretty sturdy stuff and doesn't get broken down in the digestive system, it does get pushed through the body just like everything else after a couple of days.
