Is Daylight Saving Time Bad For You?
Hugh Pickens writes "According to experts on circadian rhythms, the hour shift in sleep schedule from Daylight Saving Time can have serious effects on some people's health, particularly in people with certain pre-existing health problems. One study found that men were more likely to commit suicide during the first few weeks of Daylight Saving Time (DST) than at any other time during the year, and another study showed that the number of serious heart attacks jumps 6% to 10% on the first three workdays after DST begins. Dr. Xiaoyong Yang, an assistant professor of comparative medicine and cellular and molecular physiology at Yale University, theorizes that shifts in biologic rhythms could trigger harmful inflammatory or metabolic changes at the cellular level, to which these individuals may be more susceptible."
I was going to say, FINE! Fix it: keep DST all year round!
It sounds like the heart attacks (at least) would have happened anyway at a later point, if someone is that vulnerable to small changes.
As someone who suffers from SAD, depression, etc. I can attest to the fact that a strict sleep schedule is incredibly important to keeping me healthy and functional. DST rudely smashes all my carefully laid schedules and plans.
It may not seem like much, but even shifting things by a single hour and put me (and people like me) a very difficult spot. Light boxes and sunrise simulator alarm clocks help, but what helps the most is strict consistency in sleep/wake times. This is especially harmful to people with bipolar disorder because it can trigger a manic or depressive episode.
DST sucks!
How does this compare to people who travel one time zone over, let alone multiple time zones? Aren't these people (millions) in worse shape?
I saw an editorial cartoon perhaps 30 years ago. In the cartoon, Richard Nixon is depicted sitting in a rocking chair saying "I need to make this blanket longer, so that we can stay warm in the winter. So I'll cut one foot of the blanket off at one end, and sew it onto the other end." That's everything you need to know about Daylight Savings Time.
In other news, I believe that waking up to an alarm clock is hazardous to my health.
Parity: What to do when the weekend comes.
How about this modest proposal: let's grind up the "weak" and turn them into cat food! In fact, let's have sweeps on a yearly basis. This will finally solve our problems and allow humanity to advance to the next level. One may even go so far as calling it a.... final solution.
To solve the problem is VERY simple, but the politicians don't like it. When you move to summer time, move the clocks 1/2 hour forward instead of 1 hour... and then LEAVE them there. No more going forwards and backwards wasting time changing countless clocks and gadgets, and no more bickering about moving the timezone multiple hours forward like the UK had recently just to please some European fascists.

Concerning TFA: I guess it pushes only those people over the edge that were close to it anyway.
Apart from that: I hate DST.
If they dont want to waste daylight in summer, people should fix their timetables instead of fiddling with everybody's clocks.
The problem with DST is the free lunch mentality that goes with it. It was the first response of Congress to the "energy crisis" of the early 70's, and has remained the solution of choice for similar problems ever since. People genuinely believe they are getting "an extra hour of daylight", and expect other little bonuses to be handed to them just as painlessly. Sorry for the rant, but it's long been a pet peeve of mine.
Goddamn right, Daylight Savings Time is bad for me.
It fucks with my sleep cycle -- messes it up for a week or more -- every six months, like fucking clockwork.
Repeal it, stop it, get rid of it forever.

...OR "Shit shit shit shit I'm late for work I'm gonna be fired again!" gets to you ...
Everytime I read one of these "studies" that "shows" stuff, I can't help but think that the researcher is a press whore or is just trying to get more funding by throwing out a ridiculously convoluted "theory" to explain a simple observation. After all, the "people get stressed out when they're late for work" hypothesis doesn't get you as many grants.

One more hour of having your wife in bed with you, that would but a strain on my heart.
Turing the clock one hour ahead is bound to screw people up. So why not just turn the clock back 23 hours? The time will be the same, and we all can take that extra "Daylight Savings Day" as an opportunity to lounge around, doing nothing productive.

Next up: shifting to the metric system.
Why don't they average it out to half an hour and just leave it there? Instead of swapping an hour twice a year, swap half an hour one time and don't bother doing it again.
I think the best part of DST is the opportunity to have this semi-annual anti-DST rant-fest. It's better than sunlight!
I am not a crackpot.
I enjoy flexi-time.
thank God the internet isn't a human right.
If the government gets rid of DST for the health benefits of a few then they should be required to make new laws for other causes of stress too: How about doing federal taxes, job interviews, coming home to the wife after a sneak trip to a strip club, traffic jams, law suits, the bogyman, XMAS shopping, public speaking, jock itch, earthquakes, tornadoes, ice storms and the list could go on forever. More so for some and less for others. Maybe our government should not try to protect us from all stresses in life?
The winter is terrible whatever we do with the clocks so I vote for keeping summer time all year round - because the summer is better for the extra hour of outdoor time in the evening. When you have slaved away for decades in an office you come to realize that this evening time is very valuable, I would even go so far as to say that double summer time GMT+2 would suit us in the UK with so called summer time GMT+1 for the winter. As for suicides and health problems - well stuff em I say, the gene pool could do without wimps who cant cope with the clock shift. I worked 4 on, 4 off, 12 hour shifts in my younger days and it does mess with your health but earning money doesn't always come for free. Fix the rest of capitalism before you get excited about trivial things like DST.
Facts are history now plebs have politics for religion on social media.
When DST is active, they "gain" an extra hour of sunlight in the evening. An hour that is likely used in household stuff as people come home from work (read: lights are probably on, anyway).
Why can't we just have it at 1/2 hour and leave it at that?
As someone that has to deal with DST and timezones in the IT world I say we go with straight GMT and get rid of all of the rest. Then let local areas adjust accordingly. So in central time zone areas we go to work @ 14:00 GMT and get off at @ 23:00...

...and it's been working out fine thus far.
Back during the last time change (autumn of 2010), I decided to not change my alarm clock's time. My computer and laptop would auto-adjust, and I'd still have to change the times on my DSLR camera, e-reader, and Nintendo DS. But the alarm clock time remains the same. When the alarm clock shows "9:30 PM", I go to bed (even though it's actually 8:30 PM). When the alarm clock shows "4:00 AM" (even though it's actually 3:00 AM), it sounds and I wake up.
The effect is that my day shifts by an hour twice yearly, but I do not. It was strange for the first week or two, having everything around me shifted by an hour (giving me an extra hour in the dark morning, and an hour less after work), but that's much better than the two weeks it would have taken me to even begin to adjust to an altered sleeping schedule.
Soon I'll find if shifting my day back (moving an hour from my morning to my afternoon) will feel as strange as it did in the autumn. One thing I do know for sure, I won't lose an hour of sleep in the transition.
Fine, as long as the regular business hours occur while it's light outside where I live...
Right, do you begin to see a problem with this now? Not to mention that some people simply can't handle a nocturnal lifestyle...
It's bad for me. Twice a year it causes me severe depression as I'm reminded that I'm living in a country where the people that pass the laws think they can "gain" an hour of daylight by changing the clocks. For fucks sake, just wake up sooner and leave the clocks alone.
In other news, I'm kind of tired of time zones as well. I should disagree with some one on the phone about what time it is. it's the same time every where. What difference does it make if the sun rises at 06:00 or 18:00?
We have daylight savings to *save daylight*. Because in winter-time, we have less sun.
The human mind is closely connected to the sun. Less sun means less happines. Your health might also be connected to this. E.g. you move less when there is less sun, and you get less excercise.
I also have to point that there seem to be no study that proves that removing DST means less suicides or heart attacks.
Be that as it may, not having daylight savings time makes people spend more time in the dark, which may also cause depression.
Yes - the problem is that we have to change it at all, not that the sun goes down an hour later (and comes up an hour later). I prefer the light at the end of the day myself, so, indeed, make it DST year round. Problem solved.
My name is BMO and I live in Rhode Island. We here in the Northeast US are far enough east that during the winter, we go to work in the dark and we come home in the dark. Unless you have windows in your office or stock room or machine shop, or whatever, you never see the sun except on weekends. It's like being divorced and having partial custody - of sunlight.
The Eastern time zone is so wide that it stretches all the way to the Eastern border of Illinois. This is just nuts. When DST finally shows up in March, suddenly the sun sets at a reasonable hour.
New England and NY should secede from the Union and join the Maritime Provinces simply to get a sane time zone.
I'm sorry for ranting, but I'm tired of my Seasonal Affective Disorder and I can't wait for DST to get here. See? My SAD is showing!

DST starts roughly 80 days after the solstice and ends roughly 50 before the soltice. Changing clocks based onthe season rather than the actual amount of daylight or the time of sunrise is wasteful.
Since there are only around 300 million people in the USofA ... and none of them can drive more than 1 car at a time ...
All we'd need to do to completely eliminate the carbon footprint of our cars is to ...
Replace 300 bulbs.
Or 100 people replace 3 bulbs each.
I think your time scales are out of sync.
The problem are the earlier sunsets -- oh I miss you Sun!
For those areas affected, for the next DST, just go 30 minutes in the appropriate direction and then STOP CHANGING THE CLOCKS FOREVER AFTER.
Tada, Simple cure and one final gig for the Y2K / DST programmers.
Having DST in winter is useless because of that later rise of the sun, around my place it'd mean the sun would only rise around 10 o'clock.
When I hear about the health issues of some it makes me wonder how they cope with a night out in town...
"The likes of Facebook and WhatsApp are free to those whose privacy is of zero value."
In other words, people who are already in trouble feel compound effects with other changes in their lives.
Can an hour or two really have such a severe effect? If that was the case, shouldn't there be a massive effect when travelling and crossing time zones? A quick PubMed search didn't throw up any studies with jetlag and suicide or heart attack.
You're talking about results of a self-selected study, essentially. Most people who travel have a choice about when to do it, and don't do it when they're not up for it. Start involuntarily loading millions of people into airplanes with no regard whatsoever for their current health status and moving them to new time zones, then see what effect jetlag has on their health.
"Convictions are more dangerous enemies of truth than lies."
the summer is better for the extra hour of outdoor time in the evening.
Hate to break it to you; it's a number on a display. You're not getting an extra hour, you're getting a different number.
fix the rest of capitalism before you get excited about trivial things like DST.
As long as people actually appear to think that they magically get extra time because the numbers on the display say one thing I'm afraid fixing capitalism is out of reach. After all, if the boss turned the clock back eight hours I'd assume that people would just keep working at the end of the day...
Fine, as long as the regular business hours occur while it's light outside where I live...
Right, do you begin to see a problem with this now?
Yes. Regular business hours should be 24/7.

Changing the clock is idiotic. If anything, working times should be shifted, not "time" itself.
For the last years, since I don't watch broadcasted TV anymore, I only became aware of the DST day because my computers showed a different time than the clock in my microwave.
DST is also known to significantly boost traffic accidents after the switch, as people are tired and make more mistakes while driving.
It's time to abandon this archaic switch.

Or, better yet... keep standard time year 'round so that on the equinox, the sun will rise at approximately 6AM and set at approximately 6PM.
File under 'M' for 'Manic ranting'
The question I have is how much does DST have to do with it and how much is simply the time of year? It is possible that people are simply trying to stay awake longer than the available light. I have read elsewhere that being up after dark is not good for you, though like every other study I have to ask myself how much is this based in the factor being studied and how much is this simply a life-style factor?
Jumpstart the tartan drive.
"outdoor time" implies "time outdoors after work but before the sun goes down" So DST does in fact affect "outdoor time" if you're on a fixed work schedule.
I don't think anyone actually thinks they get more free time.
What you do get though is light that lasts longer into the evening which is great for those of us who don't live near the equator (and by Scandinavian standards Italy and the continental US are pretty damn close to the equator).
Where I live the sunrise in mid-december is generally around 9:30-10:00 in the morning with sunset just after 14:00. In fact, with standard office hours we basically have sunset before 17:00 betweeen late october and early february with sunrise during this period occurring at the earliest at about the same time as you're on your way to work in the morning.
If we used summertime all year round the period during which sunset occurred before the time that most people get off from work would be shortened to mid-november to mid-january which means more sunlight overall. That's the difference most people would be interested in.
This is counting dusk and dawn as time when the sun is up. If you count it as time when the sun is down then we don't actually get to experience sunlight after work until the end of february (and considering that this isn't summer dusk and dawn but rather the sun lazily dragging itself over the horizon just enough that it's no longer pitch black I don't really want to count dusk and dawn in the winter as time when the sun is up).
I know I'm not alone in preferring more light in afternoons and evenings even if it means that the sun won't be up until after the morning coffee break rather than before...

Time is a human invented concept to explain movement in the fourth dimension. It doesn't necessarily have to exist, but our concept of hours and calenders help us explain the phenomenon of why right now the state of the world is different from where it was in the perceived past. With that said, a different number is the same as an extra hour; its all relative and made up anyways.

Actually, I think that if the switch to Standard Time occurred at 2am on a Monday, and then the switch to DST occurred at 4pm on a Friday, everyone would be happy.
It basically gives you an hour longer to sleep in on a Monday in the fall, and lets you off work an hour early on a Friday in the spring, giving you the weekend to start re-adjusting. Everyone gets what they want with the least amount of stress.

Here in Canada, most of us are far enough north that our summers are bright, DST or not. Here in Vancouver at "only" 49 degrees north, the latest sunset (if we stayed on standard time) is about 2025 PST, with twilight until nearly 2200 PST in June and July. Further north it's brighter, later. I've been in Yukon (63 degrees north) in May when it was like a bright overcast day at 0100. How much more do people want?
By the same token, our winters are dark, no matter what we do. The earliest sunset in Vancouver is about 1600 PST, and the latest sunrise is about 0800 PST.
I think messing with the clocks is pointless. There may be a sweet spot, say, around 40 degrees north, but Canada is well north of that.
...laura
I'd be fine with that...if I got off at 4!
And I know that I am not alone in preferring more light during mornings instead of afternoons and evenings. If mornings would be darker than they currently are, it would be even more difficult to get up, especially if you are night owl.
Well, for a large part of the year mornings here in Sweden are pitch black with normal time so from our point of view having DST all year round wouldn't make much of a difference there, we'd still be getting to work while it was pitch black for quite some time but at least when we got off from work in the afternoon there'd be a few less weeks when it would already be pitch black again.
As I stated, with normal time we have "sunrise" (beginning of dawn) around 9:30-10:00 in december with sunset (end of dusk and beginning of actual darkness) around 14:00, in practice we have a couple of hours of sunlight in the middle of the day. Saying you want "more" sunlight in the morning implies you're lucky enough to live somewhere where the sun is actually up in the morning all year round...

We could go to 10 minute time zones! Or just have everyone set their clock to GMT and just have some people getting up and going to work at 2am...
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
Given that the whole basis of our calendrical system is that at "noon", or "midday", the sun is supposed to be at the meridian point of its path across the sky, that is the most logical way to do it. Especially since nowadays, a significantly greater portion of the year, including most of when there IS sunny weather, is spent off of that kilter.

Daylight Savings Time is just getting your ass out of bed earlier while pretending you're not. If you like to have light in the afternoon after you get out of work, go to work earlier and leave earlier. You're probably a techie like most of us, so you can probably work flexible hours like most of us. It's different if you're a factory assembly line worker and everybody has to be there at once for the line to roll, or a schoolteacher who's got to be there when class starts. (It's also different if you're a farmer and your cows are going to get up at dawn whatever time the clock says, but since most small farmers tend to also have town jobs, having dawn be later is a real pain.)
So stop messing with everybody else's clocks and get your ass out of bed earlier if that's what you want to do. Real morning people do it anyway (as do people with little kids.) Non-morning people don't want to get up anyway, and often don't. It's only you half-assed morning people who insist on adjusting the clocks to pretend you're not getting up as early as you are.

Someone might want to explain that it isn't time that changes... just the hands on a watch (or clock). The "circadian" stuff stays exactly the same.
No one ever had to evacuate a city because the solar panels broke!
An early estimate of the 8.9 magnitude quake's effect on the planet shows it sped up rotation by about 1 microsecond.
So all we need is enough huge earthquakes to change the day by an hour -- ergo, no more need for daylight saving time! Okay, there might be a few undesirable side-effects...
I guess you didn't get it. Isn't the question "Is Daylight Saving Time Bad For You" ?
How about going further and ask yourself "what's the point of DST" ?
What grand socialist/communist/fascist design is it to herd a nation of people to wake up earlier when the "market" of businesses itself can just as easily define an earlier starting time for business? They've easily defined varying closing times depending on the needs of their business already.
There's no meaningful, proven savings, so why bother messing with everybody's clock? Everybody means every nation gets dragged in because it's costly to have mismatched starting times between countries.
It's a useless anachronism that gets worse when Presidents like Bush come along and push tweaks to it that again don't help or fix anything except make it more "fun" to have more darkness in the winter. We have GMT -- we should just stick to that.
Regular business hours aren't 24/7 because some businesses don't get enough customers at night to make it profitable for them to remain staffed and open for business. What you propose doesn't fix that.

At least in the developed countries, we should move to constantly adjusting time, anchored either at sunrise (always fixed amount of daylight in the morning) or at sunset (fixed amount of daylight after work). So probably, to stay in familiar time ranges, either sunrise would be at 06:00 every morning, or sunset would be at 18:00 every evening. Of course then we'd need time areas instead of time zones, for example each state being it's own time area in the US, and time in that zone set by some suitable point in each area.
Or it wouldn't have to be anchored exatly at sunrise or sunset either, but that could drift too. The point is, there would not be a large change two times a year, which both maximizes the damage and reduces the advantages as it still isn't optimal for large part of the year and for different locations at different latitudes.
So each clock would be set to UTC, and would calculate the correct local time to show for it's set time area. Clocks would probably show time both in local time and in UTC, as for example TV schedules would need be in UTC except for very local channels. Technology is approaching point where there is no real need to have synchronized clocks accross large areas: businesses are largely inter-time zone already so exact local time in any give time zone doesn't mean much, and we're moving from broadcast media to time-shifted and on-demand delivery of media content.
And then there would be extra coolness to mechanical clocks able to show correct local time for any given time zone, as I believe the mechanism would need to be quite complex, possibly out of scope of building such a thing out of Legos, even :-)
Some people are morning people. Such people struggle to stay awake at night and spontaneously wake up in the morning.
Some people are night owls. Such people struggle to get up in the morning and aren't sleepy in the evenings (even with only 5 hours sleep the night before).
And you want to make it even more difficult?!? Why? If you want to get up earlier, then do so, but don't force us night owls to struggle even more than we already do.
At least morning people only need to keep their engines running in the evenings (hard enough), whereas night people must actually get them started in the mornings (even harder). And if a morning person really wants to, he/she can actually go to bed earlier, much earlier, and many do. Night people don't have the option of getting up any later.
And it's not just a matter of "going to bed earlier". Do you think I haven't tried that? What about all the years I went to school and work? Do you think I didn't try? (Uni doesn't count. Fewer contact hours. ;) I've solved it for the time being by becoming a freelancer.
For some people, going to bed earlier simply doesn't seem to work. I don't know why. And I would not be surprised if this is the cause of many health issues, but because it's the norm, these issues would fall below the radar.
If you want light at the end of the day, try moving further North...you'll get light long into the night - far enough north and you'll get 24 hours of the stuff (in the summer when the DST is in effect).
Problem solved: instead of changing clocks, make school/work/pub closing times all run one hour earlier.
Same effect, just it also makes the sun correct so that the middle of the day (and daylight hours) is (approx) 12 noon not 1pm every day (or 2pm on double summer time).
Going to sub-Sahara Africa is an interesting experience - dawn is (approx) 6am +/- 30 mins, dusk is (approx) 6pm +/- 30 mins all year round - none of this day light saving clock changing.

Kinda pointless up north. My city has 8h of daylight for most of December and part of January, for example. If you split it around noon, it would come up at 8:15am and be down by 3:45pm on the 21st, and we're only 300mi north of Seattle.
Most of Canada has DST, but my region doesn't. Well. Sort of. We're ahead of the sun by 1h year round. (So in the above case, sun is up at 9:15 and down at 4:45).
Never saw much use for DST myself, seems like something you'd trick kindergarteners with.

I live in Finland which is even somewhat darker during wintertime than Sweden. But I know that the darker the morning (not necessarily only at the exact time I wake up) is, the harder it is for a night owl like me, to wake up early.
In my opinion people should wake up even later during wintertime. It is quite unnatural to wake up in darkness.
You are able to enjoy a sunset more because an arbitrary device now has a higher number displayed on it?
The sunset doesn't occur any later, it occurs at the exact same time, they only difference is what that time is called. What's to stop you just getting up earlier?

Warning: this article may contain humor, sarcasm, parody, and perhaps even irony. Read at your own risk.
Seriously. If we really wanted to "save daylight" we'd be IN DST during the winter, NOT during the summer WHEN WE HAVE THE MOST DAYLIGHT!!! Besides, you can't "make more daylight" or even "save" it. The amount of daylight is set by the orbit of the Earth around the sun and the Earth's axial tilt, NOT by some arbitrary clock setting. All DST does is de-tune people from the natural rhythms of nature. It's illusory and false. That is all. .... by the way, how the heck does one get a carriage return to actually work in these comments. my paragraphs always get run together ...... :D
Hear, hear. I'm a semi-pro cyclist and I'd prefer more daylight in the late afternoon/early evening for training.
Are YOU using the TOOL, or is the TOOL using YOU? Think about it!
I live in Minnesota, which is in the northern continental U.S at 45 degrees north. When I was younger I had a factory job that ran from 7:00 to 17:00 Monday through Friday, and 7:00 to 12:00 on Saturdays. The shop had no windows or natural light except for a few small, north-facing windows in the truck dock and office areas. It was not a great neighborhood, and windows invited burglars and vandals. The interior lighting was provided by lines of bare fluorescent bulbs that were significantly dimmed by layers of grime sprayed continually by the machinery. One of the occasional tasks to do when it was slow was to mop the light bulbs with a rag on a stick. The lunchroom was interior and also had no windows. There was enough light to work by, but not much more.
In December and January, we would arrive at work before dawn, and leave after dusk. On Saturdays, we would leave the cave-like darkness at high noon, and on those clear winter days I often felt like a vampire being exposed to the sunlight.
It seems that daylight savings time was geared expressly towards making a job like mine slightly more tolerable. The only problem is it never helped me when I could have used it. I didn't need "more daylight" in the summer hours, I needed to have more daylight opportunities in the winter!
All in all, Daylight Savings Time means almost nothing to me except inconvenience.

Naw...can't do that... It's gotta be someone or something else's fault!
In jobs where they have shift-rotation (monitoring something 24hours/day), shift-rotation plays all sorts of havoc with people's biological clocks -- much more severely than DST...
I wonder if there is a reciprocal effect on the shift to 'Standard' -- i.e. do health problems rise, or do they fall? I.e. is it the change in time or the 1 hour less sleep we have over a weekend?
To the person with health probs "caused" by DST -- seriously, just think about planning the shift over 10 days. I.e. change the time you go to bed/get up by 6 minutes a day starting 5 days before the change. It should be gradual enough to not disrupt your body clock.
Also you might find melatonin or tryptophan to help shift your body clock. I found it useful to "pre-shift" my body-clock to 'European-time" when I went on vacation, so I had no jet-lag when I got there (I wanted to enjoy the short time I had there, so I did the time-adaptation before the trip).
Personally, I'd prefer we stay on DST all the time, as I'm usually a late riser, and if I want to do anything outdoors, the extra time in the evening helps -- but a true-computer geek wouldn't really care -- "what's daylight"?... :-)
But, what do you do with all the extra, fat cats wandering the streets?
Do we start culling the weak and grinding them up into dog food?
