Daylight Savings: Body Clocks Reset - ABC News

We cross multiple time zones all the time and keep a pretty erratic sleep schedule...

I wonder how this effects our health on a daily basis...not just twice a year?

"More than 1.5 billion men and women are exposed to the transitions involved in daylight saving time: turning clocks forward by an hour in the spring and backward by an hour in the autumn," wrote Imre Janszky and Rickard Ljung, health and welfare researchers in Sweden. "These transitions can disrupt chronobiologic rhythms and influence the duration and quality of sleep, and the effect lasts for several days after the shifts."

Janszky and Ljung said that sleep deprivation can affect the cardiovascular system, leading the vulnerable to have heart problems in the days following Daylight Saving time changes.

Take some sleep deprivation courses and find out for yourself.

Not as much as dispatch calling at 2 am with a hot load.

Daylight Savings: Body Clocks Reset - ABC News

We cross multiple time zones all the time and keep a pretty erratic sleep schedule...

I wonder how this effects our health on a daily basis...not just twice a year?

The researchers found the change affects the health of the 'vulnerable', [elderly? confused? ] but that's not most of us. Humans are amazingly adaptable: the introduction of efficient artificial light was a much bigger change, and we adapted to that without much trouble.
In my experience, we can 'get used' to nearly anything, even erratic sleep schedules, if we continue to do it. Those who don't find it comfortable quit doing it and find something that offers a predictable schedule, like working in a cubicle devoid of natural light, lol.

Many studies were done on those of us who worked shifts at the agency. For the most part we worked a 6-2 rotating shift. 6 days on, two off, changing shifts every week. All studies, including the one by John's Hopkins said the same thing. Shift work kills. It shortens lives by years. Our shifts were just ONE of the contributing factors to the early age of death there. The AVERAGE age of death was 52. NOT counting accidents. Few I knew when I worked there are alive today. Lack of proper sleep is DEADLY.

 

[Ragman]

Shhhhhh!
I'm trying to sleep.

 

[layoutshooter]

Yeah, the "Z" monster is coming!!!

 

[iceroadtrucker]

In the Service We called going from one time zone to another the Timewarping. Shooter now Marine you know darn skippi you can stay up for 136 hours with only 30min of rest once every 24 hours. & marine you will not have a problem doing so. Thats an order Marine. ARUGH!!!! Hellinacellweek. ROTFLMAO HG!!!

Just personal experience, I can't say what others feel or need, but with me if we could stop our 14 hr clock (HOS) and take a nap it would be much better. There have been many times that I have had to "push" through because I could not afford to stop. How safe is that? Many times when we have been sitting, I would get extremely sleepy...take a nap and then be awake 3/4 of the night...short naps are great!

My van doesn't go fast enough to make crossing multiple time zones a problem. Maybe if I cross a time zone on November 2 at 02:00 just as we go off Day Light Savings Time I'll turn into a zombie or something.

On December 31, 1999 I talked my two kids and 7 neighbor kids, we were all staying at a hotel, into riding in the hotel elevator just before the stroke of midnight. Midnight came and went and all the kids are still with us. So much for Y2K.

Just a little research says that's BS: there's nothing to back it up but a lot of questionable 'studies' [people reporting their experiences sleeping & driving or on shift work] most conducted by groups with an agenda [the Academy of Sleep Medicine, whose 'research' is often cited as supporting things like the apnea regs DOT is considering, are a group whose members have a decided interest in promoting the existence of sleep disorders, but no actual facts behind it].
The only truly independent research I found was conducted on animals, and may or may not be the same for humans.
The most that can be said with certainty is that sleep deprivation has been "associated with an increased RISK of high blood pressure, heart attack, obesity & diabetes" which is a whole lot of maybe/maybe not, we don't really know, could be other factors involved, etc.
Even the [presumably unbiased] CDC states that sleep disorders have been "insufficiently linked to motor vehicle accidents, industrial accidents, medical and occupational errors" - hardly sounds like "lack of proper sleep is deadly" is anything like a proven fact.

Shift work, in and of itself, doesn't kill, and isn't the problem. Those who work first or second shifts don't have the same problems as those who work third shift. It's the third shift workers who tend to have the most problems, and the shorter lifespan if they work third shift for most of their lives. But changing shifts, as Layout noted, can be an even bigger problem, since it takes 2-4 weeks to get use to a change like that, and when you're changing shifts every week you never get the chance to get accustomed to it.

Third shift isn't necessarily the same thing as sleep deprivation or sleep disorders. Many third shift workers aren't sleep deprived or have sleep disorders at all. Having managed 24 hour restaurants and worked plenty of third shift jobs, I've been more interested in those types of studies, and they all say the same thing, that third shift workers have more health related problems than the other shifts, and they tend to not live as long.

In expediting, where the thought of a regular shift and regular hours of sleep is amusing at best, the potential for increased health problems is certainly there, because it's not only mostly night work, but it's wildly varying shift work much like Layout was talking about, only it happens more often than once a week. That's why in expediting you need to grab as much sleep as you can whenever you can, because you need more of it in order to counter balance the disrupted natural biological rhythms.

I used to work 3 shifts, 1 week turnaround...it was nasty...as Turtle said...NOT good.

 

[Monty]

Lack of sleep makes me .... sleepy!

Yupper thats correct If you get a co driver dont get a newbie. Not worth the headache.

Somebody mentions HOS.... That's why I'm glad I'm in a van. I can take a nap without having to worry so much, and yes it does make a difference. If nothing else, pressing on when you're tired because you've got that blasted 14 hour clock staring you in the face can't be good.

The "Law of Unintended Results" strikes again.

This is why I like HOS, I have to get sleep and not be an idiot by driving on four hours in a 48 hour period.

I can't say I've ever done that. Somewhere along the line my body won't let me pull off a stunt like that, and I'll have to stop for a few more hours. Maybe not all at once, but the accumulated time will be more than four hours in forty-eight. By that time, Tinkerbell has flown in through your passenger side window and she's giving you directions to your next stop. Thanks but no thanks.

I think because it varies wildly it is easier to deal with than weekly rotating shifts. We never really get an established pattern (1 week) so that in it self becomes our "pattern" and like you said: "Grab as much sleep as you can, whenever you can..." At least we have the luxury of going out of service sleeping or just OOS when ever is necessary.

I used to run a night linehaul that started between 8:00-9:00 P.M. It took me a few months to adapt to it. I mentally and physically set my internal clock 12 hours off. It worked fairly well with my family's schedule until the weekend.

Moot's point was largely ignored by the FMCSA in their latest scam of the new HOS PRM.
according to the FMCSA we are incapable of getting ANY sleep. unless it is between midnight and morning.
and we must follow a scheduled sleep pattern.
just one more thing to add to the court challenge following the new rules to come.
