While some people would consider these things amazing facts about the human body, we're sitting here in a sea of "WTF" moments. It's so crazy to think that your mind has a mind of its own. No, we're not high, just really contemplative at the moment. In a matter of seconds, your body can go completely haywire for seemingly no reason. On the contrary, you can think your body is reacting to one thing, when it reality, it's reacting to something entirely different.
Are you overwhelmed already? Good, us too. It's time, once and for all, to break down all these WTF body facts and really get to the heart of the matter, pun intended. In the video above, we run through nine facts that warrant some serious explanation, which is exactly what we're about to get into. Buckle up, y'all.
Charley Horses Are Your Muscles Spasming
Most people are under the impression that a charley horse occurs after some sort of strenuous activity. In reality, you can be sleeping and get a charley horse. It's a muscle spasm that can be brought on by dehydration, potassium deficiency, and poor circulation, among other things.
Itchiness Comes From Your Brain
Whenever you have an itch, it's not actually your skin that's experiencing an irritant. Well, not entirely. You have itch receptors in your skin that send a reaction to your spinal cord and then to your brain. If it weren't for your brain telling you to scratch, you wouldn't, even if the irritant remained. Only when you've scratched the itch, are those receptors satisfied. Additionally, your brain actually identifies the slight pain from scratching as relief — giving way to the term, "it hurts so good".
Brain Freeze Is Just A Rapid Headache
Medically speaking, brain freeze is called sphenopalatine ganglioneuralgia. No wonder we've shortened it down, huh? What's actually occurring is that the two blood vessels that bring blood to your brain are halted by the cold. The immediate pain is your body rushing blood to the area to heat it back up.
Chewing Gum Really Does Help Your Ears Pop On Planes
We always thought this was just one of those urban myths that moms tell their children on airplanes. Turns out, it's entirely true! Chewing gum actually helps equalize the pressure in your ears, which is what's being compromised during lift off.
You Can Brush Your Teeth Too Hard
Harder isn't better when it comes to teeth, guys. Brushing too hard can lead to the breaking down of enamel — causing your mouth to have a painful reaction to certain foods and temperatures. If you find that your teeth hurt when you eat something cold, that's a sign to start brushing less vigorously.
Goose Bumps Have No Purpose
Many moons ago, when humans were hairier goose bumps were meant to ward off threatening situations. They caused the hair on the body to rise, making the person look larger. Now that humans don't have as much hair, they're just a bunch of prickly bumps that look like razor burn. That said, the response still remains the same — i.e. you get goose bumps when you're cold/afraid.
Yawning Doesn't Wake You Up
It used to be believed that yawning increased oxygen levels which, in turn, wake the body up. That's no longer what the medical community believes. Turns out, yawning keeps us cool. Opening your mouth wide heightens blood flow to the skull. The cool air we're taking in then changes the temperature of that blood flow, cooling down your brain/body.
A Hiccup Is A Spasm Of The Diaphragm
When you take in air, your diaphragm contracts, right? Well, any disturbance to that —taking in too much air, anxiety, eating quickly — and your diaphragm goes haywire by way of spasming.
Blushing Happens From An Adrenaline Rush
The entire body is covered in veins, including your face. When those face veins dilate — as a result of an adrenaline rush — they send a rosy color to our cheeks. Some studies, specifically one done in 2013 by Dutch psychologists suggests that blushing is an evolutionary trait. Apparently, humans are more likely to forgive people who blush after a "transgression".
In conclusion, the human body is F'in weird. At the end of the day, the best thing you can do is take care of yourself and hope for the best! But remember, even the craziest health and fitness junkie can experience these oddities.
