Ten Weird Things Our Body Does and Why
Our body does curious things, like yawn or
hiccup just to name a few. But why does this happen? After doing some
research, I've compiled a list of 10 of the most common-yet-odd things
our body does with simple scientific explanation of the “how” and “why”.
These are the questions you've always asked yourselves but have never
gotten answers to.
Alcohol-Induced Blackouts:
If you ever indulged and consumed large amounts of alcohol, there's a
good chance that you cannot recall some of the time while you were
intoxicated. Studies show that alcohol can prevent the brain from
transferring data from short-term to long-term memory. It interferes
with your brain's receptors that transmit glutamate, a compound that
carries signals between neurons. They are in-charge of sending signals
between parts of the brain. This causes some neurons to work, while
others are blocked, effectively preventing different parts of your brain
from communicating with each-other and you from remembering events that occurred during that time.
The Appendix:
For years, doctors treated the appendix as a vestigial organ that is
more harmful than useful. Appendixes can become inflamed and rupture,
posing a serious threat to our life. Doctors would perform unnecessary
appendectomies on healthy appendixes for years, as a preventative
measure. After years of research, however, researchers finally
discovered the reason we still have the appendix – it provides a safe
haven for the good bacteria that live in our guts in times of severe
sickness, keeping them safe while the body fights the infection allowing
them to return to the digestive system, boosting our immunity .
A Lump in your Throat:
Have you ever felt like there’s something in your throat when you know
full well that there isn’t anything there? This is most common when we
get bad news or when we’re on the verge of crying. This reaction is part
of the “Fight or Flight” mechanism in humans when they are under severe
stress or are in danger. Part of the response includes hastened
breathing. This is aided by your vocal chords expanding to allow more
air intake. When you then try to swallow, your muscles effectively work
against each-other, causing the lumpy sensation.
That shiver down your spine
That shiver in the base of your spine, often accompanied by goosebumps,
can happen in different situations. It often occurs while you’re
experiencing a stressful situation, when your brain releases large
amounts of adrenaline into your system, increasing your alertness and
reaction time. Adrenaline also causes hair to stand on end and your
muscles to contract. This can also happen when experiencing other
intense emotions, such as love or when you hear music you really like,
as they too can cause the release of adrenaline.
Wrinkled Fingers/Toes:
You probably noticed that after spending a
prolonged time in a bath or a pool, your fingers and toes become
wrinkled. Scientists now believe they’ve solved this mystery;
Experiments have shown that people with wrinkled fingers/toes have a
better grip of wet surfaces. It is believed that this has helped our
ancestors use tools better in watery conditions. Their enhanced
abilities improved their survival rate, leading to the gene that causes
finger-wrinkling to become as wide-spread as it is today.
Motion sickness:
Many of us can suddenly feel sick when
they’re in a vehicle in motion, such as cars, ships and airplanes. The
feeling is usually that of dizziness and nausea, with possible vomiting.
The reason for this is that your body senses one thing, while your eyes
see something different – for example: you’re sitting in ship, and
while it looks like the water is calm, your inner ear senses that the
ship is rocking. This leads to a sense of imbalance within the inner ear
which in turn leads to nausea, which, if not cured, can lead to
vomiting.
Tickling:
We’ve all been tickled sometime in our life. It can be fun, but most
people don’t like it and would rather avoid it altogether. Recently, a
researcher named Christine Harris offered an explanation that might
surprise you: She claims it may be a way to teach us fighting skills.
She points out that tickling is often performed by family members,
causing the recipient to convulse and try to “escape” from the sensation
quickly, and thus teaching the recipient how to escape from an attacker
without causing physical or psychological harm.
Phantom Vibration Sensation:
Do you ever feel like your phone is
vibrating, pull it out only to discover that it isn’t? This is a known
medical condition, called “phantom vibration syndrome”. Currently, the
most likely explanation for this is that your brain is misinterpreting
signals it is getting from your body due to slight movement of the
fabric of your clothes, believing it’s the phone.
Yawning:
It’s so contagious, just looking at a picture of a person (or animal)
yawning, or even reading about it now, may cause you to yawn. In 2014,
an encompassing theory finally emerged, explaining that the body yawns
to cool down the brain. Yawning draws in cold air and increases the
circulation in the brain, removing excess heat. It’s known that our
brain heats up during stressful situations and before exercise, as well
as when we’re tired. And when we’re bored – the increased circulation
keeps the brain more alert.
Hiccups:
Everyone goes through a bout of hiccups during their life, and except in
rare cases, this involuntary reaction dissipates quite quickly.
Scientists now believe that hiccups evolved as a way for infants to
expel air from their stomach, allowing them to burp themselves and
effectively suckle milk. This theory is corroborated by the fact that
only mammals hiccup.
