11 Simple Explanations for Strange Body Reactions

11 Simple Explanations for Strange Body Reactions


Have you ever felt like you’re living in
a body you literally know nothing about? Ooh. Freaky Friday! Every once in a while your eye starts twitching
by itself, your stomach starts singing like a whale, or you get covered in goosebumps
for no reason at all! It’s time for you and your body to get to
know each other better, and these 11 facts will help you with that. 1) Why do your muscles twitch for no reason? It’s kinda embarrassing when you have to
explain to someone why you’re constantly winking at them. If your eye starts to twitch occasionally,
it’s a signal that you’re dealing with stress or having a hard time trying to get
good sleep. If not, then you probably drank too much coffee
or ate something extremely sweet recently. The twitch itself is harmless. It’s caused by muscle fatigue and overstimulation
from your brain. 2) Why do we shake when it’s cold? We’re all familiar with uncontrollable chattering
teeth and shivering legs when we’re cold. This happens because all your muscles are
slightly, yet rapidly, moving to generate some heat from friction. Rub your hands together on a cold day, and
they’ll become warmer. This is the same thing, but on a small scale. Your brain works like a conductor. No not Leonard Bernstein! It detects the temperature of your skin. If it’s warmer than 98.6°F – it’ll
send a signal for it to start sweating. If it’s colder than that – it’ll send
a signal for your muscles to start shivering. 3) Why does your leg fall asleep? It’s scary to stand up from your desk and
have the sensation that one of your legs is useless now for some reason! Don’t panic, we all know that it’ll wake
up in a while, even though the process will include a complete lack of control and a few
moments of unnerving discomfort. This happened because you were sitting in
an odd position. The way you sat restricted the amount of blood
that could get to your leg. Only ten minutes without proper blood circulation
will cause this numbness, and the uncomfortable feeling afterwards is the sensation of blood
rushing back in to every bit of your leg. Yep, pins and needles. 4) Why are your eyes wet when you wake up? Sometimes it’s not only that, but you also
might wake up with a crusty mess in the corners of your eyes. It all happens for the same reason. You see, when we sleep, we don’t always
keep our eyes tightly shut. To compensate for the lack of protection,
and wash away all the dust that might settle on your eye during the night, special glands
in the corners of our eyes produce tears. And, when you feel tired and are getting ready
to go to sleep, your eyes water from all the yawning. Yawning applies pressure to the lacrimal glands,
and at the same time blocks tears from their regular path to our eyes. That’s why they overflow as soon as you
stop yawning. 5) What about yawning when you don’t want
to sleep at all? Basically, yawning isn’t only supposed to
happen when you’re sleepy or bored; that’s just the most common circumstance for it. Fun fact: parachutists often yawn right before
they get ready to jump from the plane! I wouldn’t call that a good moment to take
a nap, nor would I say that skydiving is the most boring thing ever. Ha ha. Try it sometime! Yawning is basically stretching your jaw,
and inhaling as deep as you can. Both actions make the blood in your vessels
rush to your head, and spinal fluid go down your spine. Surprisingly, it’s a way for your body to
shake you up! Whenever you feel stressed or anxious, you
might yawn as your body prepares itself to deal with it. Yawning also has psychological reasons. You’ve probably noticed that it can be contagious
– that’s because we’re a highly social species, and as such, we need to synchronize
our cycles of sleep with each other. In short, when one person starts to yawn from
fatigue, he or she sends a signal of fatigue to others around and makes everyone sleepy. Well, it turns out, yawning is magic! 6) What are eye floaters? Have you ever seen these strange ghostly looking
flies that seem to float aimlessly right in front of your eyes? Or maybe even inside your eyes? Don’t be afraid, these aren’t flies at
all. They’re eye floaters. They’re especially easy to see if you look
at the blue sky or other light and clear scenes. Floaters aren’t exactly objects; they’re
just tiny imperfections in one special part of the main body of an eye, called the vitreous. We can see them because these structural imperfections
stand in the way of the light that passes from pupil to retina, which forms your vision. So you don’t have to rush to an optometrist
the next time you see them; they’re usually perfectly harmless! 7) Why does falling asleep sometimes feel
like literally falling? The worst kind of waking up is when you jerk
or jump, startled, with the terrible sensation that you fell off your bed, or a cliff. It turns out this happens right after you’ve
fallen asleep, at the exact moment all your muscles simultaneously relax. Your brain may mistake it as a distress call,
because normally if all your muscles relaxed, you’d fall. To prepare you for the fall, your brain will
naturally send a lot of quick signals to your muscles to make them work again. This phenomenon even has a special name – hypnic
jerks. The same thing also happens on a smaller scale,
making your legs or arms twitch when you’re falling asleep. 8) Why do your legs feel lead-heavy when you’re
afraid? When startled, or just scared, your legs might
become as heavy as tree trunks; your heart will be pumping and your skin will get covered
in goosebumps. These are all result of the same process – a
reaction to adrenalin coming into your blood flow. When adrenalin kicks in, it triggers what’s
called the ‘fight or flight’ reaction. This reaction causes increased muscle tension
and blood flow, making your legs feel heavy. All your body systems become highly alert,
getting ready to act hard, and act fast. But at the same time, the reaction could go
two different ways: you might run like an Olympic athlete, or you may not be able to
move a single muscle. The reason is that there are two kinds of
reactions to a dangerous situation. You can deal with it by overcoming it, or
you can avoid it completely. 9) Why do your fingers get all wrinkly from
water? Because it’s easier to pick fruits from
trees in rainy weather with hands like that. No, seriously, let me explain! The wrinkling itself happens when small blood
vessels constrict under the skin; but that’s not the most interesting part. Scientists discovered that if the nerves in
your fingers are damaged, the wrinkles won’t appear at all, no matter how long they’ve
been under water. That means that wrinkling happens because
of a specific reaction of our body to water; it’s not just a quality of the skin itself. So, it must be important for some biological
reason! Further tests have involved trying to collect
wet glass marbles with dry hands, and with wrinkly wet hands, and they proved that it’s
much easier to collect those marbles with wet hands. The same goes for feet too – it’s much
easier and safer to stand on a wet surface with your feet covered in wrinkles. I guess it’s nature’s way of improving
our grip in a slippery situation! 10) Why do joints pop? Even if you don’t always notice that horrifying
sound because of your own bad habit to crack joints, you’d recognize it anywhere. To be fair, it’s even worse when you just
stand up from your desk and hear a click, as if you’ve somehow hurt yourself or broken
something. That’s not the case at all. It’s been proven that cracking joints doesn’t
even affect our wellness that much. The clicking and cracking sounds happen when
a serious force pushes on a joint, bending it in a way that causes a small bubble of
gas to escape, and deflate. Um, sort of like a joint fart. This bubble appears naturally in every joint
of your body, and doesn’t pose any threat, just like joint cracking itself. Do you have a bad habit of cracking your joints? Or are you one of those that can’t stand
the sound? Let me know down in the comments! 11) What makes your stomach growl? Belly bubbles, gut rumble, a rumbly in your
tumbly – call it whatever; we all know this embarrassing sound too well. What’s not as well-known is what causes
it. In basic terms – your brain is mocking you
for not eating. I know it sounds strange, but how else would
you explain this: When your stomach is empty, your brain sends a signal to start the process
of digesting something and transporting it further down the digestive system. But there’s nothing to move except gas,
which is what makes all the noise. So just put something down there, will ya? Hey, if you learned something new today, then

  1. All of these happen to me and I never knew why, now when I watched this video, I learned 11 things that always happens to me, thanks.

  2. I knew someone who was seeing floaters and he decided that he was going blind, even after seeing an eye doc. He also thought he was going to die because of elevated liver results….again a doc told him that it was fine. It just meant that he was overweight.

  3. Why was this video taken down then reuploaded?

    Maybe it was Obama? Sonytv? Vaccines? Or maybe it was 5-Minute Crafts?
