It ’s that time of year again , folk music . The Night are drawing in , there ’s a nip in the breeze , and the street are fulfil with tiny demons and hob arm with goodie old bag for treats – and , if you ’re unlucky , certain tricks for those who displease them . That ’s proper friends , it ’s spooky time of year .

These mean solar day , Halloween is a mostly civil social function , but thatwasn’t always the typeface . Back in the nineteenth and early twentieth centuries , it was a night of dangerous prank and vandalism . Rather than concern about their houses getting TP’d , there were reports of people literallydying of frighton their front porch .

Of course , that was over 100 old age ago , when medical knowledge was n’t as advanced as it is now . We ’re certain the medical examiner record the cause of decease as well they bang how , but you’re able to’treallybe scared to death – can you ?

Is it really potential to die of fright ?

“ Yes , it utterly is , sort of,”Dr Philip Lee , consultant physician in acute medication and medicine for the elderly , told IFLScience .

“ Can one be frightened to dying ? Yes , ” Dr Martin Samuels , a neurologist and program director for Interdisciplinary Neuroscience at Brigham and Women ’s Hospital , toldABC Newsback in 2006 .   He ’s an expert on the phenomenon of sudden death , and he ’s dedicated year to studying the how second , why s , and who s of death by fright .

“ There is definitive evidence that one can be scared to expiry under sealed and very specific circumstances . ”

How   can you fail of fright ?

When it comes to being scared to death , there are basically two means you may go , aver Lee .

“ If you have an underlying centre shape , or hardened arteria due to high line of descent atmospheric pressure , smoke , cholesterol , etc , then the chance of you dying of a sudden shock does increase , ” he explained . “ Either from a heart blast , or a stroke . ”

In this case , the reason of death is a huge surge of Adrenalin from the learning ability , which pushes the trunk into quick fight - or - flight style . Your heart beats faster , your pupils distend , and blood flows to your sinew , all in a prehistoric endeavour to escape risk .

However ,   a sudden influx of adrenaline into the heart can cause a grave stipulation hollo ventricular fibrillation – where the heart quivering ( or “ fibrillates ” ) rather than beating decently , and bloodline is not pumped through the organic structure . Thatcan be fatalon its own , but it ’s especially dangerous when fuse with another issue of the internal secretion surge : the release of Ca into the ticker .

“ Calcium cannonball along into the heart cellular telephone , which causes the heart muscularity to squeeze powerfully , "   explained Dr Robert Glatter , an emergency physician at Lenox Hill Hospital in New York , toLive Sciencein 2015 . " Basically , in a monolithic answer , the calcium keeps on pouring in , and the heart sinew ca n’t relax . ”

“ It ultimately leads to a drop in blood pressure , because without blood for the mentality , you lose consciousness , ” he explain . “ It does n’t have to be a individual with pre - existing heart disease , although those people would certainly be at higher risk . ”

This is n’t the only path it can happen . Under the veracious portion , a sudden fright – or , in fact , any strong emotion – can take you out bybreaking your pump .

“ [ It ’s ] a circumstance called takotsubo cardiomyopathy , where a sudden shock or grief causes heart failure and you die from that , ” explained Lee . “ Basically too much noradrenaline [ or ] epinephrine , and the bottom of your heart stops pumping properly . ”

Takotsubo cardiomyopathy israre – although potentiallynot as rare as we think – and while it mostly affects women , it can strike anybody . Other than the fact that it can be triggered by sudden stress , researchersdon’t know too muchabout how it happens , either .

“ I have caseful of tiddler with absolutely no sum disease who died on entertainment - park rides , ” Samuels told ABC News . “ It would be like get an tremendous dose of speed or ecstasy . ”

Oh , and the name ? It fall from the grisly consequence the condition has on your heart . The left heart ventricle balloons out , so that it “ looks like a sportfishing pot for devilfish from Japan , ” Lee tell IFLScience .

“ Tako = devilfish , ” he explain . “ Tsubo = pot . ”

But does it really encounter ?

Getting scared to demise may be rare , but it ’s far from theoretical – there ’s plenty of example of people being frighten off their mortal coil throughout history .

In 1855,Hannah Rallinsonof Sheffield , England buy the farm after being tell a peculiarly scary ghostwriter story – her death , the medical examiner ruled , was “ certainly … because of the fright she had received on the previous daylight , up to which prison term she was in perfect wellness and spirits . ” And two years after that , a teen , Robert Mitchell , become flat after a farmhand dressed up in a blanched sheet to scare him on his path to collect some milk .

Then there ’s the case of Kenneth Lay , the founder and CEO of energy company Enron . In 2001 , the company crumble into the prominent bankruptcy in US account at that percentage point . Shareholders charge a $ 400 billion lawsuit , and Lay , along with several other executives , were indict for a diversity of charges – only Lay , unlike the 21 others who faced trial , never saw a 24-hour interval in prison . Why ? You guessed it – the fright of getting his deserts killed him , pronounce Samuels .

“ He was in his 60s , probably go to prison , likely for life , nothing he could do about it , ” he toldABC . “ All you could say is that it is the perfect set up for the sudden death . ”

Another doctor , cardiologist Dr Holly Anderson , order ABCabout a 60 - year - older fair sex ’s reaction to bad news show about her husband ’s health . As the span leave the doctor ’s office , Anderson recite , the charwoman feel a sudden tightness in her chest and she was ineffective to breathe .

“ After I had whisked her off to the emergency room and glom her up to an ECG , I was surprised to see her whole heart had stopped moving , yet she had perfect blood supplying to the philia , ” Anderson said . ” She was so emotionally overwhelmed about her husband ’s condition it literally stopped her heart . ”

In fact , it ’s likely more rough-cut than you consider . According to Samuels , there ’s about one sudden destruction every day in any major metropolis – a number which increase after major calamity . For good example , after theFukushima disasterin 2011 , the rate of sudden cardiac and unexpected demise in nearby Iwate prefecturemore than doubledcompared to the former class , and in 1994 , when Los Angeles suffer one of the strongest earthquakes ever put down in the US , rates of sudden cardiac death instantly increased by afactor of five .

“ My own view is that any homo is potentially at peril . We all carry this short bomb inside us , ” Samuels toldABC . “ We ’re all at risk . If the situation is just right , if the tension is bad enough , if it ’s discriminating enough , if there ’s no room out , any of us can die . ”

shivery ! So should I be disturbed ?

Well , when it do to pass away of intense stress , you should likely not , uh , strain about it too much . Just think about “ Mrs AB ” , an apparently respectable 43 - year - old Canadian woman who dropped dead after underage and uneventful surgery . Puzzled , her doctors spoke to her sister , who uncover that a portion teller nearly four decade originally had told the adult female she would die at 43 .

“ We enquire if the severe excited latent hostility of the patient superimposed on the physiologic strain of operation had any bearing upon her expiry , ” thedoctors concluded .

In any case , it takes a big event to affright a individual to decease – and it may not be the sort of matter you bear .

“ citizenry ’s conscious conception of how panicked they are is n’t correlated at all with the anxious system ’s literal reaction , ” Samuels explained in a 2012 audience forNPR . “ In the yesteryear , the great unwashed have essay to give multitude what are call stress tolerance trial . They show them spiders and see how high their blood pressure would go , how tight their fondness rate would go . It turns out that there ’s not much correlation between what people say frightens them and what indeed really does scare them and cause this autonomic violent storm . ”

In other words , while a life - changing event like a tsunami or the death of a loved one could feasibly frighten away you to death , you ’re unlikely to meet the Grim Reaper this weekend while pass out candy .

“ you could have a sudden cardiac - related event interrelate to an adrenaline surge , but I think it would be a stretch to say you could get that from someone coming in a werewolf costume to your front door,”saidDr Vincent Bufalino , a cardiologist and president of Advocate Medical Group in Downers Grove , Illinois . “ This is the variety of affair that you ca n’t prepare for . If it happens , it happen , and you hope your consistence does n’t overreact to that event . ”

Samuels agrees . “ I do n’t believe there are any studies showing that Halloween falls into this category [ of events that can cause sudden end ] , ” he told ABC .

But if something does take you by surprisal , there ’s some good advice out there on how to cope . The best part is , it ’s easy – you ’re doing it right now .

“ Things like taking a few cryptical breaths might seem kind of silly , but when you ’re breathe , it makes the heart slow down a little bit , ” advised Humaira Siddiqi , the headman of psychological medicine at Kaiser Permanente in northern Virginia , inThe Atlantic . “ You ’re consciously slowing down the body ’s good-hearted response , and when you do that , the grip the sympathetic organization has on the body is loosened , and you ’re allowed now to relax and get [ in ] controller . ”

“ It ’s a good affair that we have the fear response . It ’s a just thing that we have anxiety , and it ’s even a good thing we have depression , because they are signal or appal that something ’s wrong , ” she added . “ We ’ve evolved with care as an adaptive mechanism . If something like that could kill us off , we would not have evolve with it . ”
