DESCRIPTION:
With the conflict between Iran and America plus people talking about
World War 3 we wanted to investigate why war is addictive.
TRANSCRIPT:
If you're like me you woke up on Jan 1st 2020 like hashtag new year new me
babe made yourself a smoothie started to meditate and then BAM we're at
World War 3 memes started we kept refreshing Twitter we watched the news
obsessively and honestly I felt weirdly fascinated by the concept of war a
variety of psychological studies have found that soldiers who returned from
war actually end up missing it we all clamor to the cinema to watch movies
about war and it turns out there is a reason why it has to do with our shared
history and your body archeologists believe that we were less violent as
hunter-gatherers because we were more nomadic and we had less
possessions essentially we just had less to fight over now I stay put in my
home I have things like my phone which I'm literally in love with and if anyone
does touch her though she'll feel bad laughs as humans when we started
to stay put create agriculture build walls and borders and our populations
grew that's when the concept of a large-scale war actually began and our
physiological response to it created an innate fascination your body is
controlled by the brain and nervous system which is acted on by hormones
hormones are chemical messengers released from glands in your body that
influence the nervous system to regulate your behavior and physiology
if you are experiencing armed conflict firsthand playing call of duty or even
just reading about an impending war your brain will initiate a stress response
the hypothalamus will release corticotropin-releasing hormone which acts
on the pituitary gland of the brain to release adrenaline tropic hormone
into your bloodstream at this point the ACTH is pumping through your
body where it ends up passing through these little adorable adrenal glands
that chill on the top of your kidneys these glands use the ACTH signal
to now release adrenaline and noradrenaline into your blood which act
on receptors throughout your body your heart rate increases your breath
quickens blood vessels constrict and you experience a feeling that is
unsettling and thrilling known as the fight-or-flight response designed over
years of human evolution to protect you from danger your physical strength
is temporarily increased your body has a decreased ability to feel pain and
other hormones like cortisol and dopamine are released which make your
attention hyper focused the stress response is a natural high a natural
biological process where you become focused hyper present and amped
to fight the neuroscientist Jim Foss explains that by activating your arousal
and attention systems stressors can also wake up the neural circuitry
underlying wanting and craving just like drugs do the stress
created by playing Call of Duty or watching a war movie is a really clever way to
target this system and the Hollywood Machine does a good job at creating a
lot of war movies that feed into this biological urge you get to leave the theater
and go home and return to home yo stasis because you're safe and sound
which is one theory why civilians make it a rush from these movies because
for the most part we'll never have to face war as for the soldiers who have
returned from war and claim that they miss it the studies show that they have
become accustomed to these higher levels of stress and therefore they feel
that it's necessary to feel that stress all the time their brains will be wanting to
seek out these feel-good hormones and this leads them to think that they miss
the stress of war although acute stress may lead to a natural high chronic stress
has extremely negative effects on your body especially due to the hormone
cortisol which over time decreases your immune function causes impaired
digestion increased nervousness susceptibility to infection fear and desensitization
if stressors are too strong and too persistent and individuals who are biologically
vulnerable it can lead to disease living life is to be an impressionist dance with
stress a biological response that the concept of war hijacks if people don't
understand that the body can actually crave acute stress then we may end up
treating war like a thrilling game and if that's the case with our world leaders then
we may all be in danger which is ironic because we evolved the fight-or-flight
response to keep us safe from immediate danger but if we don't understand it
properly it may be the exact biological response that leads to another sad
devastating war during these precarious times it does feel scary so you can
share this video with people so they can understand more about what's happening
and their thanks for watching and we will see you next week for a new science video
QUESTIONS:
1.Explain what Hijacks are.
2..Discuss how bad news affect our brain.
3.What comes to mind when you hear the word war?
