Blue Lights To Reset Internal Clocks
holy_calamity writes "Researchers at RPI are testing the effects of putting blue LEDs inside cars to keep drivers alert. People driving through the night are much more likely to cause accidents because our circadian rhythms just want to sleep — blue light at around 450nm wavelength can fool them into thinking it's morning and keep them awake."
.. there really is justification for people pimpin' their rides????
Thank You for your cooperation.
I'm rarely awake before 2pm, you insensitive clod!

Yes, I know there are times that we've all had to drive with less sleep than we should have... but is this a good answer?
To me it would seem to inspire false confidence on the part of the driver, where they might think that they could stay up and not have to worry about falling asleep driving since they had their blue lights blinking or whatever.
I'm thinking that the real solution is making people in the public more aware of the dangers of driving with too little sleep. Everyone knows they shouldn't drink and drive (yet many still do) but not enough people realize how dangerous driving when tired is.
Most of all, i hope they don't put these in 18-wheelers are another way to squeeze yet more driving time out of the guys.

For me, when I start to see the blue light is when I normally GO to sleep.
I have found that soft red light used to illuminate my dash certainly doesn't keep me awake. Maybe a brilliant electric blue would at least keep me more awake. Whether it "simulates morning" or if it's simply brighter/more intense, as long as it works is all that I care about.
I know bright light can certainly do that. I was working as an extra on a movie night shoot. They had banks of thousand Watt lights all over. I was up till dawn but never felt drowsy at all.
Interesting. VW uses this wavelength for its gauge lighting in most of its cars. I always thought it was for looks (as the red/blue combo does look pretty good). Perhaps the blue was chosen to help enhance nighttime alertness as well.

"blue light at around 450nm wavelength can fool them into thinking its morning and keep us awake"
I need to install one of these on top of my monitor!
Is the light going to reduce night vision? Will we end up with aware drivers seeing less? Perhaps if we knew how bright the light had to be, we could tell.
I need to try this in the cubicles of developers over there.

Is it really unusual for a third of accidents to happen at night? Sounds about the proportion of the day that's spent in darkness.
That's like doping in sports: you don't realize you're destroying your body, and after prolonged use you end up in a wheelchair. I wouldn't be surprised to see the number of nightly accidents go up in the long run when the blue lights are introduced.

This must be why, in recent years, I have felt increasingly alert upon entering my server room.
And here I was thinking all those PC, external hard drive, UPS and KVM (?!) makers were just being vindictive.

How soon until they can put this in textbooks? Now that would be handy...
I find a flashing blue light in the rear view mirror certainly wakes me up.
Seriously though, it would be better to just not drive when tired. Also wouldn't screwing around with your internal body clock mess you up more?
I use a special full spectrum light to keep me from going into involuntary hibernation in winter. It is really bright, especially in the morning, and not alway very pleasant. If only blue light is enough from 2.5 to 7 lux it might be a good alternative to prevent burning and tired eyes before the days begins. It makes you wonder what biological basis there is for blue light to set circadian rythm.
Smoke me a kipper, I'll be back for breakfast!
It's going to take more than a blinking LED to convince my body that I haven't worked a double-shift at 7-11.
Are you kidding? Every time I drive on a long trip I stew about the high beam light being bright blue. It ruins my night vision every time I accidentally look right at it. I keep thinking about taping a red lens over it. Well, maybe that irritation keeps me awake.
I can fall asleep with the sun out, the TV on, and the radio. But when the Wii starts flashing blue I just start looking and can't go to sleep. I always thought it was because I was a Nintendo Fanboy, but I guess the Blue Light has an effect.
Who are these circadian rhythms, and why do they want to sleep? Also, if they sleep, can I still stay awake?
I'm not going to discount the possible correlation between certain wavelengths and sensing it's daylight. But it sounds problematic to me. One blue LED has amazing illumination power, so not only will it likely affect your night vision but it will illuminate all the flaws in your windscreen, as well as enhance the reflection of your self.
Those of us unfortunate enough to buy hardware with blue leds on it can share this fact, it's damned annoying.
There is no sanctuary. There is no sanctuary. SHUT UP! There is no shut up. There is no shut up.
Make this your screen color and stare at it when you get up. I assume most of us here do. :)
The only problem is that blue light ruins your night vision, which would conceivably cause more accidents.
If you're tired just find a motel and go to fucking sleep!
Blue wavelengths also have the nasty side effect of destroying night vision almost instantly, fooling the pupils to contract - likely for the very same reason it fools the rest of the body into thinking its daylight too.
Not a desirable or safe side effect when making something specifically intended to be used for driving in the dark. It's why the military uses red lights in their vehicle cabins and cockpits.
When I read the headline I thought they meant internal clocks in electronics... now that would be fun wouldn't it :P
You could just play death-metal at full volume. It more than keeps me awake. In fact, every time I listen to DethKlok, I feel like head-butting an ox.
Help fight spam
Perhaps I should email that company with a question to see what response I get:
"So if your blue light device is designed such that I no longer need to worry about driving when I'm really tired, does that mean that if I do fall asleep at the wheel, spin out of control and kill an innocent pedestrian, it will have been as a result of the failure of your device to do its job such that I can pass on all legal liabilities to you then?"

How about red lights flashing at about 4Hz for exercise?
Perhaps a good way to force product turnover. Of course, it is probably limit your drivers.
I prefer the "u" in honour as it seems to be missing these days.
Of course, the best thing would be to find a place to take a good rest. The second best thing is to talk to the driver on a subject he or her has good knowledge about. Ask him or her on the subject extensively during the drive. That will activate the portions of the brain that does the thinking and keep the driver very awake. Driving, particularly at night, can be done very well while under hypnosis, which is nothing but a normal state of partially asleep. It will work for a couple of hours.
TFA mentions "light showers" at rest stops... ok, not too intrusive, optional, but may lead you to push yourself harder than you should.
Blue LEDs in your face?
HELL NO!
I tape over the blue led for my brights because even that is too much of a hit on my night vision.
"Shifting it (body's clock) by eight hours takes at least 10 days, and very few people are capable of doing that,"
BS
Some of us are able.
Some of us are natural night people.
Some people have different sleep patterns (body working on a longer day).
You gotta wonder who this hypothetical "normal" person they talk about is, and how much his life must suck.
As this is regarding truckers though, you can bet there will be "un-official" deployments of this.
One other poster/former trucker has posted about being taught how to lie on the logs the very first day.
Anything a company can do for money, it will.
Now I can proportion blame for all hte times I couldn't get to sleep. It was Dell's fault for putting blue LEDs on my laptop and charger which sit on the desk in my bedroom. Bastards ruined my sleep patterns.
What if Tetris was invented by Nazis?

I always found blue instrumentation lights very annoying and I vowed never to buy a car with them. This article might provide a rational explanation for my tastes. I also don't like red instrumentation lights, amber is bearable, green is best. Maybe it's just a traffic light syndrome :-)
So now we will get jet lag from driving a car at night?
How long until our brain gets used to this signal just being that "blue widget" again and starts filtering it out?

One that hath name thou can not otter
I have one of these bright light lamps that uses an array of blue leds that emits light with the wavelength around 460 nm. Actually the leds are only blueish, and emit a bright white light. I imagine the article is talking about the same thing, so the leds don't resemble the "super blue" leds that everyone is annoyed with.
I'm a bit skeptical though If I would like to use this kind of device in my car, because this simulation of the sun can mess up your sleep rhythm if you take it regularly while driving, or so I could imagine. I use the bright light every morning, to make me wake up and boost my moods generally during the dark winter time, which lasts a long time in Finland and can really bring my moods down.
I also suffer (when viewed from the modern societys point of view, where you go to work from 8-16 and that's it) from an irregural rhythm of sleep, so I feel really energetic during the nighttime, so I need all the help I can get.
Maybe the idea is good, but I'm not sure if I want to be artificially kept not from sleeping while driving my car. Why not take a break ? This brings us down to the question of the modern society and the ideas that companies come up to boost peoples "work effectivity". I would rather take a siesta during the day than drink coffee and look at bright lights, but sadly that is not possible in so many places.

FYI: I saw a program last night that showed how insomnia and sleep deprivation adversely affected the thalamus. A damaged thalamus can cause coma and death, with on going dementia as being the classic symptom.
Don't be apathetic. Procrastinate!
Light, in general, suppresses the production of melatonin by the retina, and melatonin plays a role in maintaining circadian rhythms. Higher levels of melatonin make you more sleepy, which is why melatonin is sold OTC as a sleep aid.
One of the treatments for some sleep disorders is called "light therapy", and involves having a fairly bright light in view for about an hour after you wake up. This inhibits melatonin production and resets the circadian cycle to keep that as your wake-up time (which also places your go-to-sleep time at an appropriate time of day). Recent studies indicate that the suppression of melatonin production peaks around 450nm, so a blue light around that wavelength is far more effective per lumen than broad-spectrum light.
So, if you're a person who does a lot of night driving (you work the night shift, you drive trucks at night, etc.), this is great for you, because you can get by with a much dimmer light, perhaps even one in the vehicle while you're driving. If you just need this for one or two nights, you're a bit likely to give yourself jet lag by screwing up your sleep schedule.
FTA:
"Nearly 30% of all fatal accidents involving large trucks in the US happen during the hours of darkness"
So, 70% of accidents still occur during the day.
There's a reason trucks drive at night: it's when there are no cars on the road. No soccer moms riding the left lane under the speed limit, no kids blitzing through traffic. A large number of truckers prefer night driving; I'm actually surprised there aren't MORE accidents at night.
Cool tech, but I hate when they throw in useless statistics to try and justify it.
So the answer to sleep deprevation is to extend sleep deprevation? Brilliant (not). Those truckers that already spend 12 to 18 hours on the road may now be spending even longer periods thanks to blue light science. Hmmm...what could possibly go wrong?

http://en.wikipedia.org/wiki/Circadian_rhythm
Disruption
Disruption to rhythms usually has a negative effect. Many travelers have experienced the condition known as jet lag, with its associated symptoms of fatigue, disorientation and insomnia.
A number of other disorders, for example bipolar disorder and some sleep disorders are associated with irregular or pathological functioning of circadian rhythms. Recent research suggests that circadian rhythm disturbances found in bipolar disorder are positively influenced by lithium's effect on clock genes.[14]
Disruption to rhythms in the longer term is believed to have significant adverse health consequences on peripheral organs outside the brain, particularly in the development or exacerbation of cardiovascular disease. Timing of medical treatment in coordination with the body clock may significantly increase efficacy and reduce drug toxicity or adverse reactions. For example, appropriately timed treatment with angiotensin converting enzyme inhibitors (ACEi) may reduce nocturnal blood pressure and also benefit left ventricular (reverse) remodeling.
Shift work, particularly the night shift, has in December 2007 been listed by the World Health Organization (WHO) as a "probable cause" of cancer.[15]

Seriously, I bought a Sony stereo for my truck, and it doesn't support dimming at night - I ended up putting a piece of black plastic over the face so I could see oncoming traffic.

Bought a whole bunch of Ultraviolet LED's surplus. Don't know what they use them for. I put a bunch of them on a proto board, each with a series resistor, then connected all of those in parallel. It was really bright. Very interesting.
This changes w/age. People in their fifties have usually an internal clock of some 24 hrs. Some can have even 30 hours or more at their twenties. Old people can have internal clocks of 19-20 hrs, which is why they tend to get tired early in the evening and then start waking up in the very early morning hours.
Some of us don't think clearly until after the sun has been down a few hours. Some of us have been that way since we were six despite the fact that we were raised by dads who kept us on a military time clock--and it didn't make one damn bit of difference, because we could invert the clock in one day by staying up until morning.In my case I don't think it's really about my internal clock, as you could really time your clock by me when I was a baby, regarding both sleeping and eating. My folks made me get up at 07:00 every morning in the week for the 17 years I lived w/them. Now I'm soon 34, and I have a day off from work, and I woke up at 13:48. Any why ?
Because it was supposedly so important to watch a few more videos from Beyond Belief 2.0. I went to bed at 05:30 (am), just because I was so darn stubborn to keep on watching the videos about a subject that I found highly interesting. I actually played solitaire for the last few hours just to keep myself active so that I don't get too sleepy.
My theory is that at least some of the so-called night people are just like me: They're too intensive, too driven and too interested in things to let go of the day - it's like every day you go to bed it's a little death. And don't get me wrong, it's wonderful to get there when you're really tired, but the thing is that I still don't want to go to bed at night. I can say that to me going to bed feels like a punishment every and each day, and I drag it off for as long as I just can. If I didn't do this, I'd probably be more effective many days, because I would've slept as much as I really needed, had I gone to bed in good time.
I have a friend who has an intensively driven personality just like me, and he tends to do just the same things - stay awake just for the sake of it, like I guess we did when we were children. It was just so much fun to be able to stay up after your bedtime. Maybe this is in part is an effect of how we're brought up. Some Freudian would surely conclude that I want to stay up every night just to defy my parents who always put me to bed when I was a child.
Only when I got to be an adult did I realize that morning people aren't "faking it". Get this: they are really rather happy its morning! All that "good morning" stuff--its sincere to them. And you have to lie and say "good morning" right back to them or they won't understand you. Well, if I wasn't always tired in the morning w/having to get to work, maybe I'd feel better about mornings, too. As it is, I pay the price for not going to bed in time especially in the mornings.The lyf so short, the craft so long to lerne
I thought that we had hit the pits with Toyota's MAINT REQUIRED flashing LED on the dashboard. It undoubtedly was the dumbest piece of instrumentation I had ever seen. Let me explain -- The flashing of this led has nothing to do with the mechanical state of the car. Nope, no instrumentation connected to that LED except a timer. Reset it buy pressing a few buttons here and there and you dont need MAINT ! Then it got worse. BMW comes up with a even lousier idea -- If your car changes lanes, and you dont have the blinker on, the steering wheel vibrates ! And now this. In all honesty, the mind bleeds.
Guys, if you want to _really_ make better cars give us more muscle, smoother gearboxes, better crash safety and mileage. Also, do not cover up lack of innovation with eye-candy. Please leave the driving to the customer.

40 years ago, truckers had blue lights mounted under their dashboards precisely to stay awake.
and they have these twin blue led lights mounted above the rear view mirror pointed diagonally down. i can't figure how to turn them off. i thought they were for reading maps at night. perhaps honda's r&d guys are ahead of the curve here?

So this is why it is a good idea for pedestrians to have blue-lit umbrellas.
Sure blue light can cause loss of night vision and the answer to sleep deprivation is not more sleep deprivation piled on top. But, exposure to blue light does cause macular degeneration of time.

Maybe it's just because we just had a rough night with #1 (20 months) and #2 (3.5 weeks), but... Wonder if say, 30 min with a blue led headset while breast- or bottle-feeding could give a new mom a little lift.
I'm sure Windows users see the opposite effect. I know whenever I get the blue screen of death, I usually just decide to go to sleep.
The blue lights in my rear-view mirror sure wake me up!
Have gnu, will travel.
I used to make long road trips in a car with blue lighting (though, probably not 450nm) and that never helped me.
My current car has blue back-lighting in the instrument cluster though, again, probably not 450nm.
Morning light has never kept me from sleeping.
Over all, I just sleep when I'm tired. Maybe two hours, maybe four hours, maybe 10 hours. But always when I'm ready to sleep, or genuinely bored.
I'm more like a Fraggle: I can nap at the drop of a hat.
I'm not sure of the wavelength, but the blue light on my Wii keeps me awake while driving, though it's still difficult to play games that require the nunchuck.

Anyone who puts blue light in the interior of a car that is driven at night is an fool. It is a long established fact that blue light temporary night vision; deep red is less harmful to your night vision.

I'm colorblind you insensitive clod!
Here's a funny little science story. Scientists who study the effect of light on the retina are all, oh, sciency and technical. So when they talk about the wavelength of light hitting the retina, they want to be sure they're really talking about light at the retina.
In adult humans, the eye lens yellows with age (perhaps an adaptive response to help shield us from harmful blue light). Now, these sciency guys know that those yellow lenses alter the frequency of light. So, even though they are shining a wavelength of, say, 505nm into the eyes of their adult human subjects, in all their research papers they mathematically correct for the distortion of yellowed lenses and therefore always publish a wavelength like 450nm. Because that's what the wavelength will be after it goes through the yellow lenses of adult humans.
Here comes the funny part: lots and lots of other folks reading those scientific papers miss the whole yellowed lens trick, so they go off and do things like build a million blue "light therapy" boxes that are operating at the wrong frequency for adults. So, you get some folks who get the inevitable placebo effect, others who get little or no effect at all, and using light to affect melatonin is set back another ten years (which puts it almost to 0!).
In this state (MN) I believe it is considered "unlawful" to have blue lights inside your car as that color, along with red, is reserved for the emergency vehicles...

DOT's been riding company's backs about this. The law now states that you can't drive more then 11 hours a day, and can't drive or be on duty more then 70 hours in 8 days. (so no more then 8.75 hours per day average) If the company pushes you to break this law, the DOT can fine them big time. My company checks my location via gps every hour and if it doesn't match my logs, they'll fire me. I just met a guy that had that happen to him. He was using speed averaging, which, for those who don't know, means changing your logs so it shows you've been driving 65, etc. the entire trip, despite having driven over hills and through traffic.
As far as the blue lights go, I rarely turn on my brights because the blue "brights" light indicator on the dash bothers my eyes too much. I do however have "foot well" lights that are red and light up my feet. They're there for the same purpose, to help keep drivers awake during night driving.
BTW: Truck driving is a pretty nice skill to fall back on if you're in IT. There's always a high demand for drivers, and it's easy to pick back up between jobs. I found out from my recruiter that many of the new drivers she's seen are former programmers.
"That's so plausible, I can't believe it!" - Leela
I have noticed that most people, myself included, cannot focus their vision on "deep blue" (sapphire blue) glowing signs at night, those remain "fuzzy" no matter how hard you concentrate.
That's mainly because the layout of the eye's cones (the color receptors) is a sparse hexagonal array of blue sensors filled in with a randomly-blotchy sea of red and green sensors. The blue image is lower resolution than the red, green, or black-and-white. (I'm not sure if there's also an issue with chromatic aberration causing the focus to be less accurate in blue. But that would be appropriate given the sensor layout.)
Some older taillight designs take advantage of this to produce a distance cue at ranges far beyond binocular vision usability: They have a blue jewel in the midst of the red lens. When the car is close you see red with a blue dot. When it's farther away the blue "leaks" out due to the lower resolution and the whole taillight appears purple. Still farther and the blue leaks beyond the red, producing a purple taillight with a blue aura. Result: You can keep track of the car at all distances but see red only when the car is close enough to be an immediate hazard.
Unfortunately government regulations now penalize showing colors other than red to the rear.

Some states have laws forbidding passing on the right, others do not.
They were commoner in the past than now, because many have been repealed due to their tendency to imped traffic on high lane-count expressways. (I think California may have been the one to start repealing the rule.)
= = = =
What drives me nuts is that driver education classes no longer teaches a safety rule they once taught: NEVER hold the same speed as the car in the adjacent lane. To do so causes accidents two ways:
1) It turns a pair of cars into a two-lane rolling roadblock (or more into a multi-lane roadblock ditto) impeding other drivers who want to go faster (whether legally or otherwise). The result is a number of closely-packed cars behind the cars that are pacing each other. This leads to chain-reaction collisions if something causes one or both of them to suddenly brake.
2) Pacing a car means you aren't moving relative to it. So you're not triggering the motion detection mechanism in the driver's peripheral vision system. After a minute or so he forgets you're there. Then he may turn into you during a lane change or when avoiding an obstacle. Or he may startle the next time he notices you and swerve, brake suddenly, or otherwise behave erratically - and startle YOU, causing you to do the same. A near-miss if he swerves or changes lanes may also cause YOU to brake. (In addition to direct problems between the two of you, if you've collected a pack this may be the start of the chain reaction accident.)
I've always thought the rightmost continuous lane (i.e. the one that doesn't keep disappearing down exits and rejoining after) should be marked, and the speed limit should rise five MPH per lane on those to its left. That would encourage a smooth flow of traffic, with the cars on the left slowly passing those to their right. While holding exactly the same speed may cause accidents, the problems arise mainly from significant speed differences between cars and the surrounding obstacles (stationary or other cars). So though traveling faster, the drivers on the left have less processing load from tracking the nearby cars going roughly the same speed than those on the right who are dealing with cars entering or exiting, debris and cars stopped in the shoulder, nearby roadsigns and other visual destractions, etc.

Yes, I know there are times that we've all had to drive with less sleep than we should have... but is this a good answer? To me it would seem to inspire false confidence on the part of the driver, where they might think that they could stay up and not have to worry about falling asleep driving since they had their blue lights blinking or whatever.
IMHO designing car lighting so that anyone who drives at night ends up with jet lag as a way of life is a Really Rotten Idea (tm).
