Explaines 20 Weird Body Quirks to help you have an healthy life

Do you have weird body quirks? hurry up to tell the friends around you, share this post!
The human body can be quite the mystery. We've all had weird, unusual things happen that we can't quite explain. Like why does being cold equate to your hair standing up? Or why drinking something frozen gives you a headache? And just what the heck are hiccups?! All these strange body quirks do have explanations, and we're here to deliver. Check it out, hope can help you!

1. Why do onions make us cry?

How often do you find yourself reaching for a tissue while in the middle of dicing up some onions? Well, there is a scientific explanation for your body's reaction. Cutting into an onion ruptures its cells and releases enzymes that produce a gas called propanethial sulfoxide. When that gas hits your eyes, it mixes with tears and actually produces a mild sulfuric acid. Ouch! The brain signals the tear glands to keep working in order to flush the stuff out.

2. Cracking joints

We've all been told growing up to stop cracking our knuckles. But have you ever stopped to think why they crack in the first place? It's actually caused from nitrogen-rich gases which are escaping the lubricant inside the joint capsule. Once the gas is released, the joint can more around with more flexibility.

3. Goosebumps

No, that isn't the scientific name. But there is quite the scientific history behind them. Ages ago, when humans still had a natural "fur coat", your body would become warmer by trapping an insulating layer of air between the hairs. Also, standing your hair on end was intimidating to predators and enemies. Sigh, evolution has since ruined goosebumps, and now they just signal that we need a jacket.

4. Seeing stars

When you see circles, dots, or flashes in your vision, they are actually inside your eyes. Tiny clumps that form in the jelly-like substance in your eyeballs called the vitreous gel. When you see stars, you're actually seeing the shadows these particles cast on the back of your eye, where the nerves for sight are located.

5. Side stitches

Usually causes by running, or prolonged laughter, side stitches are generally due to exertion of the diaphragm. When you laugh really hard, or run really hard, you're sucking in a lot of air which fills the lungs and pushes the diaphragm down. The repetition of this spasm is what is known as a stitch.

6. Circles under our eyes

Or as some people like to generously call it, "raccoon eyes". People like to blame being tired on these dark circles, and they are right. Lack of sleep makes your skin pale, which emphasizes these circles. Age also is a contributing factor, as it thins the skin around the eyes making discoloration easier to see.

7. Itching

Why is it that sometimes we can itch uncontrollably and other times we're fine? Itching is usually attributed to a dryness to the skin that can come from over-washing. Water and soap can actually strip the skin of natural oils, which we need to keep moisturized.

8. Yawning

Yawning can be both reflexive and contagious. But we still can't thoroughly explain why we do it. Some theories include that yawning is a result of too much carbon dioxide in our blood, and our body's way of inhaling more oxygen and expelling CO2.

9. Canker sores

These small sores insides the mouth are actually small ulcers. They aren't caused by a virus, nor are they contagious, but they can be caused by certainfoods or nutritional deficiencies. Emotional stress may also be a reason for these painful pockets.

10. Ear Wax

Did you know that this weird body quirk is actually helping your body? Earwax helps to fight infection and clean the ears. When we use cotton swabs to clean the ears, we may actually be causing more harm than good by compacting the wax in the canal.

11. Brain Freeze

Have you ever drank a milkshake too fast and soon after have a horrible headache? Brain freeze, or "ice cream headaches" happen when something cold touches the nerves in the roof of the mouth, which triggers blood vessels in the front of your head to swell. Because the swelling happens so quickly, it results in a terrible headache. The solution? Eat cold foods a bit more slowly.

12. Vertigo

For some people, vertigo can really put a damper on their everyday lives. But why does this dizziness, or room spinning happen to some and not all of us? It's often caused by inner ear problems or even nerve damage, which results in a feeling of motion when there isn't any.

13. Laughing Until You Cry

We've all done it — laughed so hard that we started crying. But how does that make sense? Both bodily reactions come from very different emotions. Robert R. Provine, PhD, says that both laughing and crying are similar psychological reactions that carry higher emotional arousal. The lingering effects don't cleanly turn on and off.

14. Sleeping limbs

Have you ever felt that dull, or tingly feeling in your arm or leg like it's asleep? It's temporary and harmless, but can be downright scary in the moment. When you have constant pressure on the nerves you're leaving them unable to transmit messages to your brain, which is similar to sleeping. A quick fix is to change positions.

15. Sneezing

Did you know that sneezing is actually pretty fascinating? It begins with your nose sending a message to a certain part of your brain telling it to sneeze. This usually is due to an irritant in the nose. From there, other parts of your body require quick responses, such as you chest, throat, belly, and eyes. A sneeze is so good at sending irritants away, that they do so at a speed of
around 100 miles per hour.

16. Hiccups

Unlike sneezing, hiccups offer no obvious benefit for the body. In fact, a hiccup only occurs when the diaphragm is irritated. It contracts suddenly, drawing air into your windpipe. We don't know what exactly causes a hiccup, but for some it can be caused by anxiety, drinking a carbonated beverage, or eating hot, cold, or spicy food.

17. Ear popping

What does it mean when we have to "pop" our ears? Sometimes, our body needs to equalize the pressure between the inside and outside of the eardrum. This can be caused by a change in altitude. The "pop" is from a tube connecting your middle ear to the back of your throat. Once it "pops" the pressure is relieved.

18. Charley horse

A "Charley horse" is often used as a slang term for a muscle cramp in the thigh or calf area. But what the heck causes these painful things? When muscles stretch between two joints in the body, it causes more pressure and stress than they are used to, which means not enough blood can get to them. This is only temporary though, because as soon as you start massaging or stretching, the blood resumes it regular route.

19. Funny Bone

If you've ever banged your elbow too hard and felt a painful, numbing sensation then you know what hitting your funny bone is. That strange sensation isn't caused by hitting a particular bone, however. It's actually from hitting a nerve, the ulnar nerve, that helps you move your hand and sends feeling to your last two fingers.

20. Twitching eyes

Sometimes a twitching eye can last a few days, in even more annoying cases, weeks. But why the twitch in the first place? Involuntary blinking or eyelid spasms, called blepharospasm, is caused by an abnormal nerve function. It may also be caused by being tired, tense, or sensitive to bright lights.
