THE SCIENCE BEHIND THE SCREAM

Many like being scared.  This is not new. 
 But it is on the rise.

On a hormonal level, 

the fight or flight reflex releases hormones that give us a subtle rise.  It can be addicting.


Your favourite slasher flick could actually help you shift the pounds ...

Research has shown that the spike in adrenaline levels that we experience when watching horror movies 

actually increases the metabolic rate (that’s how much energy the body uses).

 You could burn up to 184 calories watching The Shining!


On a psychological level, 

there is an appeal to vicariously experience, the forbidden, the bizarre, or the dark.

Creepy stories allow us to release the pent-up frustrations and angers which society says we must bottle up.

It is thought that the effect of being able to “survive” a scary film could actually have a positive impact of mental health, 

and experiencing fear in that controlled environment may actually equip you to deal with frightening and stressful situations in the future.


If you’re always fighting a cold around Hallowe’en,

 then there’s even more good news as some surprising research 

has shown that horror movies may actually boost your immune system.

The “fight or flight” response to danger kick starts white blood cell production in anticipation of healing wounds and fighting infection.


HAVE YOU EVER ASKED YOURSELF WHY SCREAMS ARE SCARY?

Scientists believe it's because there’s nothing else like it in all of human communication. 

 The frequency of a scream varied wildly compared to normal speech,

 fluctuating between 30 to 150 hertz, giving it a quality that scentists call its “roughness”. Turns out, the rougher the sound, the scarier it is.

 This is the same reason why sirens and alarms modulate up and down, it makes them unsettling and difficult to ignore.

It has to do with the warning calls of primates, 

signalling when danger is near, which are basically the alarms of the animal kingdom.


THE SCIENCE OF SCARY MUSIC IN SCARY MOVIES

 Composing the perfect scary music is a science as well as an art and has a surprising amount to do with the yellow-bellied marmot.

Say what?

 Daniel Blumstein, an expert on animal distress calls, found that baby yellow-bellied marmots would scream when they were being caught.

He found that people found music with more non-linear chaotic characteristics more frightening. 

He also found that the music was more likely to be disturbing if it went up in pitch as opposed to down, 

something that he was able to link to his expertise in animal calls, 

as the baby marmot’s scream gets higher the more frightened it is.

Basically, the reason why the soundtrack to PSYCHO is a work of genius is 

because it awakens the Mama Marmot in us all.


CAN YOU BE SCARED TO DEATH?

 Ah, yes

 Because fear basically elicits your fight, flight or freeze response, you get a huge dump of adrenaline in your system. 

This slows digestion, dilates the pupils, increases blood flow to the muscles, quickens breathing 

and it is what causes your heart to go like a race horse.
Unfortunately, if the old ticker isn’t in top shape 

then this stress can actually cause damage to the heart and even cardiac arrest.


 SO WHY DO WE LIKE TO BE SCARED?

It's all about being able to separate fiction from reality in the "fear from a distance" that is a horror movie.

The brain is a complex organ but the body is relatively simple. 

Exciting and stressful situations release the same chemicals, namely adrenaline, dopamine and endorphins,

 it is the context in which these are released that dictates whether or not we enjoy them.


SO DO YOU ENJOY SCARY MOVIES?

  1. I like scary movies--ghosts and stuff--but not slasher films. The adrenaline and fight/flight reaction could also be applied to thrillers and suspense films and shows, which I really like.

    1. Yes, I am not into slasher films -- too much gore not enough character development. And you're right, thrillers also ramp up the adrenaline rush, too. :-)

  2. No, I do not like scary movies, they usually give me bad dreams. When I used to be alone in my house and my cat would act as if she heard a noise, that would scare me. . .she was a black cat, too. I called her Chocolate. It's the things I don't like those rubber masks which cover the head either. Halloween is not my fave time of year.

    1. I left something hanging there: "it's the things I can't see which give me goosebumps and . . ."

    2. I watch fewer and fewer horror films these days because of the gore and revealing too much too soon. THE FINAL GIRLS has heart, humor, and satire in it all in one. I will re-watch that one.

      Midnight looks up and above often at night -- I figure he sees the ghost of Mark Twain crossing his eyes at him! :-)

      I am in the mood to watch the Boris Karloff version of THE MUMMY and then the 2000 version with Brenden Frasier. I am a big kid.

    3. I liked the Brendan Fraser version of the Mummy and the Mummy returns. He's a more humorous version of Indiana Jones and similar adventures. It's the bugs -scarabs that creep me out in the Mummy.

  3. So if you're in good shape, horror movies are really good for you!
    That's interesting about the pitch in music. Remember the movie Suspira and Green Goblin's unsettling score for the film? I think it was effective (although a bit weird) because it ranged higher and higher in pitch.

    1. That strange musical effect for the original THE DAY THE EARTH was eerily effective for the same reason. Brrr. :-)

  4. I am most definitely a afraid cat. I like reality based stories which can be quite horrendous.

    1. That was fraidy cat. I got to hook up my computer. The kindle spell check is wild with sneaky substitutes.

    2. I am more scared of stories based on true events, for they always end badly for the main characters. Life is like that. :-( Midnight and I are fraidy cats, too! :-)
