I've never once heard that Daylight Saving Time caused an increase in heart attacks. I've always heard there were increased deaths due to "car accidents and other fatigue related deaths", as you put it.
My brother actually had his master memoir on the effects of lighting on driving. Much of that study was spent looking at daylight savings and he found a significant increase in accidents correlated with time changes.
I remember my psychology teacher saying that a reason against daylight savings is that there are more car accidents when we lose an hour of sleep. This would still be just the one day but I don't see how that could average out in the same way as heart attacks. Does daylight savings kill people this way?
So not heart attacks. Does the less sleep impact things requiring concentration (like say dealing with moving vehicles)? Does productivity go down the one day following the clock change (or vice-versa does anti-productivity go up)?
Definitely but I don't know of any studies to back it up, just personal anecdote. I suffer from a sleep problem where I often get periods where I don't get enough sleep, where I will get maybe 6 hours for 2-3 days. The first day I'm fine as expected. After that a few noticeable changes occur. Light sensitivity sets in causing enough eye strain to cause migraines if I don't use adequate sunglasses (polarized lens, wrap around frames). Focus becomes much more flighty. If I'm doing heavy work, I get to a point where it feels like if I don't take a breather I'll have a heart attack (so I take a breather and get a glass of cold water). My body temp rises faster and drops faster, to the point where my normal comfortable 72F room has me shivering. It's hard to maintain breathing rate, get winded much easier. Strength drops off enough by the end of the second day where if I'm working a task where I'm shaping metal over an anvil, I just have to put it aside until I do get more sleep. Appetite changes toward things that give more a boost of energy instead of things that make me feel full (usually shift from meat/starch heavy to fruit heavy diet as needed). Honestly it freaks me out. My father was the same way. He died of a heart attack before he was 60. Very few people seem to understand supplements, rocker chairs and all that nonsense don't work when it's not your typical stress induced sleep deprivation. Medications are just too risky with how often I go through it. So I work around it by working on physically heavy projects on days where I get sleep and mentally heavy projects on days I don't get enough sleep. Kind of works out, get both the physical and mental exercise in moderation by necessity. Still scares me though.
My brother actually had his master memoir on the effects of lighting on driving. Much of that study was spent looking at daylight savings and he found a significant increase in accidents correlated with time changes.
Did he remember to factor in the slight reduction of accidents through the summer because more driving occurs in daylight? (Some lucky latitudes also get to largely skip having rush hour at dawn or dusk during one of the changes.)
Sleep-deprivation is probably a little bit of an exaggeration for 1 hour missed - that one hour that anyone can freely prepare for by going to bed 1 hour earlier.
Yeaaah unless you're extremely sensitive to changes in the amount of sleep you get 1 hour less sleep on one day of the year isn't going to cause sleep deprivation any more than your regular sleeping habits do.
By that logic, since everybody dies, everything either accelerates or decelerates death, nothing actually causes or prevents it. I guess the question is, over what time frame do we decide that something is meaningful or not in a "causal" manner?
In fact, people having heart attacks a few days sooner might protect someone from committing accidental manslaughter. Let's do this pointless dance four times a month!
@@gressorialNanites but every time it goes forward again it prolongs the chance of preventable accidental manslaughter, so best would be to only move the clock back, and never forward.

Depends where you live, apparently. Wikipedia opens with: "Daylight saving time (DST), also daylight savings time (United States), also summer time (United Kingdom and others), ..." I'm English, have grown up and only lived (other than holidays) in the UK, and I tend towards 'SavingS' myself.
Linguistically, it is probably a mix up of the term Daylight Saving Time and the colloquial equivalent Daylight Savings. But the singular "-s" on verbs this term is subject to, feels wrong. 'Daylight Savings killS' should be 'Daylight Savings kill', just as with any other plural noun.
For people with that 's', it's probably like "local savings bank". You give away an hour at one point and get it back later, for some benefit over that period.
I've always heard it with an s, and taken it to be possessive. As in "daylight saving's time" like, the time we have given to the saving of daylight. It's not exactly congruous with the established laws of english, but thats an extremely overrated concept. Most things in english don't follow the rules of english or are morphed over time by people who misunderstand whats going on. The word "newt" was originally "ewt" but everyone would always say "an ewt" and people mistook it for "a newt" so much that newt has become correct

Plus the increased carbon emissions because DST leads to more energy consumption (more climate change leads to more death). Plus the wasted resources spent on custom programming diverts resources that could go to something more useful (like research into curing heart disease). That the video would latch onto the most insignificant factor and claim there's nothing to see is sad.
@@PeterDSMork Why does DST lead to more energy consumption? Surely it leads to less as we tend to get up after sunrise and stay up well after sunset - so we're using an hour less artificial lighting in the evening for 6 months, and most of that time, no additional lighting in the morning.
Lots of people (myself included) have to work both weekends and nights. In my case as a train driver, I will not miss changing the time at all. For us, who are at work as the clock goes forwards or backwards an hour, it can really mess with our work schedules. Time tables are also tricky - passengers sometimes struggle to figure them out on that night. So good riddance, daylight savings time.
Take something like time tables. At night, you usually have very few trains to choose from (at least outside major cities). Say you're taking a train at 2.30 am on the night the clock moves backwards an hour. Do you go to the station at the "first" 2.30 and risk having to wait for an hour for your train to arrive, or do you go the "second" 2.30 and risk having missed it by an hour? Similarly, when the clock moves forward an hour, there is no 2.30 am at all! Train companies have had to deal with this nonsense every year we've had daylight savings. So do you just have an extra train to make sure no one misses anything? That's an expensive solution, which means extra fuel is needed as well as calling in extra staff (who would probably otherwise have been enjoying their weekend off). Or do you just have that one train sitting somewhere at a station for an hour waiting for the time table to match up again? My company has tried both, and they obviously both suck for some reason.
Every company announces how they will deal with it beforehand. As a passenger, I would read the instructions. It's been happening since the World War I, it's not a new concept. I would be happy if they cancel it, just to see the disappointed faces of stupid people who don't know what impact will it have.
Since this clock moving takes place during weekends, and almost all my devices (computers, phone, radio thermometer) does it automatically, I've several times moved between dst and normal time without even noticing/remembering whole thing.
Ive never even heard of the heart attack hypothesis... Every time it has been brought up with me it has always been about the tiredness causing spikes in things like car crashes and the like. Now, I havent actually done my in depth research on this so it could also be a myth, but Im just kind of baffled as to why anyone even made the link to heart attacks in the first place.
"Less sleep only kills people that would have died anyways". In a sense, that's always true. Car crashes only kill people who would have died anyways. Also wow that's very morbid
This is true, and an instance of a car crash lowers the instances of car crashes later in the week, assuming that person was irresponsible and going to die in a crash anyway
Hey Matt, I've often heard the "Daylight Savings Kills People" thing, but I was always under the impression it had more to do with other things than just heart attacks. Like deaths in car accidents, or even suicides due to the just general stress of less sleep. I mean I like the video but I think this just shows it is still inconclusive since it only considers one form of possible death.
I live in Queensland Australia, we haven't had DST since a trial when I was a kid. I haven't been in DST since one year we went over the NSW border one new year Eve to celebrate an hour early, then come back and celebrate again! I like no DST in summer because I get up and do stuff in the morning before work...
Interesting, but for my knowledge heartattacks weren't the issue, at least in Finland. Most news articles I hace read about the subject focus more on psychological effects, that usually are negative in both ends, because changing your routine and schedule just simply upsets people. Or maybe finnish people are just pessimistic, and instead of enjoying an extra hour, we feel it's a bother. So, much more interesting stat for me would be suicide rates and how they correlate with daylight saving. As far as I know they correlate more strongly. And in Finland, we actually have a decent yearly dataset, Yay!
it may waste money though. They had it where I used to live in Oregon, US. But where I live now in AZ, US we don't have it. It seems like just one/two less things to worry about for everyone. I know someone must be studying the economic impact also, but I'm too lazy to look it up. I rather get an extra hour of sleep tonight.
My take on this: make sure you're getting enough sleep. I stopped using an alarm to wake up a couple of years ago, and just wake up naturally when my sleep cycle is over.
I just became a subscriber and I was all excited to get an early comment on a new video. 1 day old and it's already got 500+ comments. Damn, Matt, you have an active fanbase.
Also, you can't ignore the energy saving created by daylight savings. The reduction is use, reduces the cost of energy production, this increasing access and potentially saving lives.
I don't know about heart attacks but if I remember correctly there was a study done here in Australia over a few years that showed an increase is car accidents in the week following moving the clock forward an hour so that's something to consider too.
Neither pro nor con: I'm always tired when I get up. That one hour doesn't make any difference for me. Pro: Driving in darkness is annoying. DST shifts my driving times towards brighter times. Con: It makes programming around timezones a nightmare. The timestamp "4.11.2018 1:30" in UK local time is not unique. It references *two* different points in time. So you better not fill out any forms during that time unless they have an input for the UTC offset.
To be fair, what the EU Commission said it that they want to end the mandatory time change, where the EU even decides *when* it happens, and return to the previous system where each country was free to decide when or even if they changed the time at all.
Daylight savings is the most useless invention in modern day. Once upon a time, there was a time when people was so ruled by a certain number, that it was inconceivable for them to get up one hour earlier or later. So ingrained is the time they get up in the morning, that rather than changing that, they moved the sun 15º in sky. (turned back/forward the clock one hour) It really is astonishing how people are so used to getting up at a certain time in the morning, that rather than changing that, they caused whole nations to collectively re-set their clocks. repeatedly!
IIRC, Daylight Savings also causes more traffic accidents on the Monday after we’re robbed of an hour of blissful sleep. Dunno if it the rest of the week makes up for like with heart attacks.
While the article talks about myocardial infarctions, it does not appear to specify if they resulted in a death. It would be interesting to look at more data to see if the severity of the infarction changes resulting in more, less or the same amount of deaths with either daylight savings time period.
My issue with daylight savings is I would travel east to get to work, which with daylight savings i would have the sun peak over the hills four times a year, instead of the two times without daylight savings. Well, not killing, but as certainly blinding me while driving. Likewise, at the end of the day, traveling west, i would get the sunset......
While Matt certainly has a point with this measure of statistics, that only account for directly related possible deaths from heart attacks. However losing an hour of sleep and any heavy machinery (or cars) increases accidents. While heart attack could be said to be accelerated or delayed by lack of sleep but balance out over the course of a week. I doubt it would balance out for accidents.
Argument is the people were having heart attacks. This ignores the long term effects of the yearly changes. While those haven't been studied in detail, shift work has, and has been shown to hurt people's health. Schedule changes to sleep in general have severe long term health consequences. And this is before we do any research into whether the heart attacks were more severe, or if those few extra days might have made the difference between someone going to the hospital or not.
Well this wasn't what I expected. I assumed this would be about the increases in car accidents when we lose an hour. I've heard of that, but never saw statistics proving it. There are places that don't use daylight savings so we can use those as a control if we wanted to test it.
You can't "borrow" sleeping hours and "return" them later in your day to day life. You can't sleep more on weekends to cover for sleep deprivation on weekdays. Lack of adequate sleep (7 to 9 hours every night for adults) has profound negative effects on our health.
The resulting software bugs can certainly kill you. There was an accident in a steel manufacturing plant because molten steel was cooled one hour less, medication overdose because the hour happened twice, computer crashes at hospitals, etc. Told them as much in the survey.
Ummmm... Heart attacks are not the only way people die from lack of sleep. Motor vehicle and workplace accidents go up after the change in time. Daylight savings time DOES kill people. It also lowers productivity, and is just really inconvenient for everyone.
Daylight savings time gives you more light in the morning, when you are tired, going to work, most likely to crash, it reduces the light in the evening, when you are more awake and alert. So I would say that car crashes would go down due to dst
All I got from this is that we could have daylight savings every day and perpetually push people's heart attacks until the proverbial tomorrow, thereby eliminating cardiac arrest completely. Besides, I get tired of hot tar roofing in daylight anyway; might as well cycle it to nighttime about every month.
Daylight savings time is annoying. I usually wake up between 7am and 7:30am and whenever the clock is messed with I'll either wake up between 6am and 6:30am and feel annoyed because I woke up early and can't go back to sleep or wake up at 7:40 when my alarm is supposed to wake me and feel annoyed because my sleep got disrupted. All in all, I appreciate they are considering stopping the nonsense. Also it would give my dad a bit less to complain about :D
On the other hand, Daylight Savings does indeed saves lives by reducing road accidents, via more day light illumination for when people are actually driving.
Daylight savings saves lives for people in northen regions. During the winter in Norway you'd go to work during the dark and go home during the dark if it had not been for DLS which gives you a bigger chance to see the sun which while not a lot helps against winter depressions.
But there are only so many hours of daylight. Assuming a working day of 8 hours, with an hour of commuting in it then you'd need 9 hours or more of daylight to provide some of it both when going to work and coming home. Once you have less daylight than that in the day you can only have it one end. In extreme (more polar latitudes, don't forget the southern hemisphere!) cases you'd need a large shift in the clocks to have any of the 4 hours or less of daylight fall during either period of the day. So for those places where it would make the most difference ... it can't do so for long as both ends of the day will end up dark anyway! And here's the kicker ... the time of year you 'need' to move the daylight around is when you're not on DST anyway! We all get a 12/12 hour split of night/daylight at the Equinoxes. In the EU we go back the hour to non-DST about a month after that, and forwards in the spring a week after. So during DST there's almost always already over 12 hours of daylight each day from around 06:00 (or earlier) to around 18:00 (or mostly later). I live in England, and I know as a kid, going to school for local 09:00, and home at local 15:30, it was not night, but definitely not very bright at both ends. And that's only at around 52.5 degrees north.
During the winter here i Bergen Norway we usally have abou six hours of daylight during november-january with dawn usually around 8-10 and daylight from 10-16. By pushing the clock one hour later we get more light when going to work helping us wake up etc. There is no chance of us having light at both ends, but that extra hour gives us a chance to see the dawn at least. As far south as england etc there really is no need for DLS (why is the english abriviation DST? Daylight saving time?)
Nice find, There might be many more statistics bodged by the fact of the calendar day having 23 or 25 hours out of the solar day´s 24 hours or a leap day. At least when the data is about timestamps, counting events per day.
Thanks! There's a proposition on the upcoming California ballot (prop 7) to allowing the state legislature to change daylight savings time, so definitely a timely (haha) video.
I’m actually an undergrad at Michigan, but I had no idea that the medical research from here was being used this way. That being said, the math department is fantastic and would appreciate a visit if you were ever in the area :)
I was expecting someone to have forgotten to take into account that one of the days was 25hrs, 4.17% longer, and the other one 23hrs, 95.8% as long. Leading to more and then fewer deaths simply by the days being different lengths, giving people more or fewer hours in which to pop clogs.
I always restrict the changes to five minutes per day. So it takes 12 days until I have caught up with the DST. On the other eleven days, I have my own time.
I've heard the heart-attack statistic, but the secondary statistic I've heard is automobile accidents. This might be more prominent in the USA where public transportation is not as readily available as in Europe and elsewhere.
Honestly this is the very first time I heard about heart attacks. Was quite surprised about how large the impact was, but then you explained the huge jump. But what I heard was suicides, I can definitely see the added stress causing deaths that otherwise wouldn't occur and the reduction of stress half a year later merely delaying the attempt till the next thing pushes people over the edge (so to speak).

For us, who are at work as the clock goes forwards or backwards an hour, it can really mess with our work schedules. Time tables are also tricky - passengers sometimes struggle to figure them out on that night. So good riddance, daylight savings time.
One would have thought this is figured out for decades already.
Take something like time tables. At night, you usually have very few trains to choose from (at least outside major cities). Say you're taking a train at 2.30 am on the night the clock moves backwards an hour. Do you go to the station at the "first" 2.30 and risk having to wait for an hour for your train to arrive, or do you go the "second" 2.30 and risk having missed it by an hour? Similarly, when the clock moves forward an hour, there is no 2.30 am at all! Train companies have had to deal with this nonsense every year we've had daylight savings. So do you just have an extra train to make sure no one misses anything? That's an expensive solution, which means extra fuel is needed as well as calling in extra staff (who would probably otherwise have been enjoying their weekend off). Or do you just have that one train sitting somewhere at a station for an hour waiting for the time table to match up again? My company has tried both, and they obviously both suck for some reason.
Every company announces how they will deal with it beforehand. As a passenger, I would read the instructions. It's been happening since the World War I, it's not a new concept.
I would be happy if they cancel it, just to see the disappointed faces of stupid people who don't know what impact will it have.
Since this clock moving takes place during weekends, and almost all my devices (computers, phone, radio thermometer) does it automatically, I've several times moved between dst and normal time without even noticing/remembering whole thing.
I'm so glad we're finally doing this
Just pre-ordered! I'll now have a new book to pass along to my family for a good read.... in March
Ive never even heard of the heart attack hypothesis...
Every time it has been brought up with me it has always been about the tiredness causing spikes in things like car crashes and the like. Now, I havent actually done my in depth research on this so it could also be a myth, but Im just kind of baffled as to why anyone even made the link to heart attacks in the first place.
According to another 2014 study, canceling daylight saving will not change the mortality rate. It will remain equal to 1.0 per life.
I wonder about other health concerns like car crashes and stuff like that.
"Less sleep only kills people that would have died anyways".
In a sense, that's always true. Car crashes only kill people who would have died anyways.
Also wow that's very morbid
This is true, and an instance of a car crash lowers the instances of car crashes later in the week, assuming that person was irresponsible and going to die in a crash anyway
Just pre ordered my copy! I can’t wait till March!
Hey Matt, I've often heard the "Daylight Savings Kills People" thing, but I was always under the impression it had more to do with other things than just heart attacks. Like deaths in car accidents, or even suicides due to the just general stress of less sleep. I mean I like the video but I think this just shows it is still inconclusive since it only considers one form of possible death.
I live in Queensland Australia, we haven't had DST since a trial when I was a kid. I haven't been in DST since one year we went over the NSW border one new year Eve to celebrate an hour early, then come back and celebrate again! I like no DST in summer because I get up and do stuff in the morning before work...
You silly goose, you don't want an extra Tuesday, you want a Friday.
Interesting, but for my knowledge heartattacks weren't the issue, at least in Finland. Most news articles I hace read about the subject focus more on psychological effects, that usually are negative in both ends, because changing your routine and schedule just simply upsets people. Or maybe finnish people are just pessimistic, and instead of enjoying an extra hour, we feel it's a bother.
So, much more interesting stat for me would be suicide rates and how they correlate with daylight saving. As far as I know they correlate more strongly. And in Finland, we actually have a decent yearly dataset, Yay!
it may waste money though. They had it where I used to live in Oregon, US. But where I live now in AZ, US we don't have it. It seems like just one/two less things to worry about for everyone. I know someone must be studying the economic impact also, but I'm too lazy to look it up. I rather get an extra hour of sleep tonight.
My take on this: make sure you're getting enough sleep. I stopped using an alarm to wake up a couple of years ago, and just wake up naturally when my sleep cycle is over.
I just became a subscriber and I was all excited to get an early comment on a new video. 1 day old and it's already got 500+ comments. Damn, Matt, you have an active fanbase.
As someone who lives in Arizona, the consistency of time is rather nice.
Also, you can't ignore the energy saving created by daylight savings. The reduction is use, reduces the cost of energy production, this increasing access and potentially saving lives.
Behold the potential for use and abuse of statistics. Lovely explanation and summary. Thanks for this.
Haha..."magic square mistakes"...good one.
Preordered your book, although with tiday's exchange rates, I am paying and extra 33%
If this math error helped to end daylight savings, it was an error made in a noble cause.
I don't know about heart attacks but if I remember correctly there was a study done here in Australia over a few years that showed an increase is car accidents in the week following moving the clock forward an hour so that's something to consider too.
Matt out here asking the real questions, great job.
I don't preorder stuff, usually... but I really wanted to encourage the publishing of this book, I hope it helps!
Clock-piling. I am going to use that one.
Neither pro nor con: I'm always tired when I get up. That one hour doesn't make any difference for me.
Pro: Driving in darkness is annoying. DST shifts my driving times towards brighter times.
Con: It makes programming around timezones a nightmare. The timestamp "4.11.2018 1:30" in UK local time is not unique. It references *two* different points in time. So you better not fill out any forms during that time unless they have an input for the UTC offset.
To be fair, what the EU Commission said it that they want to end the mandatory time change, where the EU even decides *when* it happens, and return to the previous system where each country was free to decide when or even if they changed the time at all.
But it is written in white letters filling the screen in a video on youtube, it must be true !`
Well, it might increase the odds of a murderer having an alibi that holds up on the day when you fall back an hour.
Daylight savings is the most useless invention in modern day.
Once upon a time, there was a time when people was so ruled by a certain number, that it was inconceivable for them to get up one hour earlier or later. So ingrained is the time they get up in the morning, that rather than changing that, they moved the sun 15º in sky. (turned back/forward the clock one hour)
It really is astonishing how people are so used to getting up at a certain time in the morning, that rather than changing that, they caused whole nations to collectively re-set their clocks. repeatedly!
IIRC, Daylight Savings also causes more traffic accidents on the Monday after we’re robbed of an hour of blissful sleep. Dunno if it the rest of the week makes up for like with heart attacks.
While the article talks about myocardial infarctions, it does not appear to specify if they resulted in a death. It would be interesting to look at more data to see if the severity of the infarction changes resulting in more, less or the same amount of deaths with either daylight savings time period.
Great to get another book, I loved things to do in the 4th dimension. Can't wait for this one
I'm so glad I live in Arizona, we ignore daylight savings.
And trust me, I'm originally from Texas, I know how annoying DST is.
Good thing they're getting rid of it, it makes the curtains fade more as well..
I was half expecting that the stats would say that there are 4% more heart attacks on the day the clock is set back...because that day is 4% longer.
Daylight savings don't kill people, people kill people
time has killed every person so far.
In European Union, people kill daylight savings
Nah our bodies just stopped working, therefor killing us.
meint48 Technically, life kills people: 100% of people who lived then died right after…
We should propose a ban of people.
So if I turn my clock backward every day I become immune to heart attacks! We found the elixir of life xD
It's an interesting argument that Neuroscientist Matthew Walker discusses in greater depth in his book "Why we Sleep". I recommend it.
My issue with daylight savings is I would travel east to get to work, which with daylight savings i would have the sun peak over the hills four times a year, instead of the two times without daylight savings. Well, not killing, but as certainly blinding me while driving. Likewise, at the end of the day, traveling west, i would get the sunset......
While Matt certainly has a point with this measure of statistics, that only account for directly related possible deaths from heart attacks. However losing an hour of sleep and any heavy machinery (or cars) increases accidents. While heart attack could be said to be accelerated or delayed by lack of sleep but balance out over the course of a week. I doubt it would balance out for accidents.
Parker savings time
When I saw the thumbnail for this video I thought it was Norman Gunston
Extra Tuesday?! Genius!
Argument is the people were having heart attacks.
This ignores the long term effects of the yearly changes. While those haven't been studied in detail, shift work has, and has been shown to hurt people's health. Schedule changes to sleep in general have severe long term health consequences.
And this is before we do any research into whether the heart attacks were more severe, or if those few extra days might have made the difference between someone going to the hospital or not.
The elephant in the room: More sunlight is good for health and can save lives!
Well this wasn't what I expected. I assumed this would be about the increases in car accidents when we lose an hour. I've heard of that, but never saw statistics proving it. There are places that don't use daylight savings so we can use those as a control if we wanted to test it.
You can't "borrow" sleeping hours and "return" them later in your day to day life. You can't sleep more on weekends to cover for sleep deprivation on weekdays. Lack of adequate sleep (7 to 9 hours every night for adults) has profound negative effects on our health.
The resulting software bugs can certainly kill you. There was an accident in a steel manufacturing plant because molten steel was cooled one hour less, medication overdose because the hour happened twice, computer crashes at hospitals, etc. Told them as much in the survey.
Lesson learned: always take Monday off after changing the clocks. Just to be safe.
Congrats on 2^7 videos
Ummmm... Heart attacks are not the only way people die from lack of sleep. Motor vehicle and workplace accidents go up after the change in time. Daylight savings time DOES kill people. It also lowers productivity, and is just really inconvenient for everyone.
Daylight savings time gives you more light in the morning, when you are tired, going to work, most likely to crash, it reduces the light in the evening, when you are more awake and alert. So I would say that car crashes would go down due to dst
Well research shows that they do in fact go up. I think ASAPscience did a video on it
All I got from this is that we could have daylight savings every day and perpetually push people's heart attacks until the proverbial tomorrow, thereby eliminating cardiac arrest completely. Besides, I get tired of hot tar roofing in daylight anyway; might as well cycle it to nighttime about every month.
Well said! Cheers to falling back!
Daylight savings time is annoying. I usually wake up between 7am and 7:30am and whenever the clock is messed with I'll either wake up between 6am and 6:30am and feel annoyed because I woke up early and can't go back to sleep or wake up at 7:40 when my alarm is supposed to wake me and feel annoyed because my sleep got disrupted.
All in all, I appreciate they are considering stopping the nonsense. Also it would give my dad a bit less to complain about :D
On the other hand, Daylight Savings does indeed saves lives by reducing road accidents, via more day light illumination for when people are actually driving.
2:40, it's actually worse than this, as the 24% increase is in a 23 hour day and the 21% decrease is in a 25 hour day!
The day this video was uploaded my mother died of a heart attack. What a coincidence lol
Daylight savings saves lives for people in northen regions. During the winter in Norway you'd go to work during the dark and go home during the dark if it had not been for DLS which gives you a bigger chance to see the sun which while not a lot helps against winter depressions.
But there are only so many hours of daylight. Assuming a working day of 8 hours, with an hour of commuting in it then you'd need 9 hours or more of daylight to provide some of it both when going to work and coming home. Once you have less daylight than that in the day you can only have it one end. In extreme (more polar latitudes, don't forget the southern hemisphere!) cases you'd need a large shift in the clocks to have any of the 4 hours or less of daylight fall during either period of the day.
So for those places where it would make the most difference ... it can't do so for long as both ends of the day will end up dark anyway! And here's the kicker ... the time of year you 'need' to move the daylight around is when you're not on DST anyway! We all get a 12/12 hour split of night/daylight at the Equinoxes. In the EU we go back the hour to non-DST about a month after that, and forwards in the spring a week after. So during DST there's almost always already over 12 hours of daylight each day from around 06:00 (or earlier) to around 18:00 (or mostly later).
I live in England, and I know as a kid, going to school for local 09:00, and home at local 15:30, it was not night, but definitely not very bright at both ends. And that's only at around 52.5 degrees north.
During the winter here i Bergen Norway we usally have abou six hours of daylight during november-january with dawn usually around 8-10 and daylight from 10-16. By pushing the clock one hour later we get more light when going to work helping us wake up etc. There is no chance of us having light at both ends, but that extra hour gives us a chance to see the dawn at least.
As far south as england etc there really is no need for DLS (why is the english abriviation DST? Daylight saving time?)
Nice find, There might be many more statistics bodged by the fact of the calendar day having 23 or 25 hours out of the solar day´s 24 hours or a leap day. At least when the data is about timestamps, counting events per day.
Thanks! There's a proposition on the upcoming California ballot (prop 7) to allowing the state legislature to change daylight savings time, so definitely a timely (haha) video.
Parker Time
I’m actually an undergrad at Michigan, but I had no idea that the medical research from here was being used this way. That being said, the math department is fantastic and would appreciate a visit if you were ever in the area :)
I was expecting someone to have forgotten to take into account that one of the days was 25hrs, 4.17% longer, and the other one 23hrs, 95.8% as long.
Leading to more and then fewer deaths simply by the days being different lengths, giving people more or fewer hours in which to pop clogs.
I always restrict the changes to five minutes per day. So it takes 12 days until I have caught up with the DST. On the other eleven days, I have my own time.
I've heard the heart-attack statistic, but the secondary statistic I've heard is automobile accidents. This might be more prominent in the USA where public transportation is not as readily available as in Europe and elsewhere.
just to be nit picking, but when the clocks go back an hour, in the UK that happens at 2 AM and goes back to 1 AM, not 1 to 12.
This filming angle could well be the cause of a heart attack.
0:41 Daylight saving hour at midnight just gave me a heart attack! And try to tell me that your clock is tilted, that would be pure madness.
One time, as we switched from Daylight Savings Time to Standard Time, I legitimately showed up to work an hour early. And it was my first day.
I wonder most about frail seniors in assisted living who experience 1 hour of forced jet lag twice a year when their schedules are suddenly changed.
I hope you can't get a heart attack for 1 hour as I've been flip flopping between day and night shifts for 2 years now at +/- 12 hours.
It means that all conditions for heart atack are preperd few days earlier. So potentialy we could regognize them somehow
_Everybody_ who has a heart attack is "only dying earlier" - because nobody lives forever.
If you murder someone 3 days before their doctor predicted they'd die of a pre-existing condition, it's still murder.
Honestly this is the very first time I heard about heart attacks. Was quite surprised about how large the impact was, but then you explained the huge jump.
But what I heard was suicides, I can definitely see the added stress causing deaths that otherwise wouldn't occur and the reduction of stress half a year later merely delaying the attempt till the next thing pushes people over the edge (so to speak).
So the fact that my sleep schedule changes basically every day means I'm gonna die like...yesterday
