Drugs Eradicate the Need For Sleep

MattSparkes writes "New Scientist is running an article on lifestyle drugs that claim to help you function on little or no sleep. I'm dubious, but the interviewee in the article claims they work well. 'Yves (not his real name), a 31-year-old software developer from Seattle, often doesn't have time for a full night's sleep. So he swallows something to make sure he doesn't need one.'" But, sleep is where I'm a Viking!

Not good.....

[BWJones]

Speaking as a scientist who used to study sleep and sleep disorders, I have to say this is troubling. Sleep has evolved for a purpose and a number of studies have shown that sleep is necessary or crucial to consolidate long term memories, stabilize mood and more. If you are a simple automaton in your job, then *perhaps* you might be able to get away with something like modafinil for short periods of time, but if your job requires thought and the use of memory and higher cognitive function, then you are doing yourself a disservice by taking these drugs. I worry that the long term effects will not become apparent until years later, like I suspect might happen with PDE inhibitors like Viagra, Cialis and Levitra.

Humans have evolved an organized architecture of sleep where we progress through a number of stages of sleep. In other words, sleep is an active state that is not homogenous in that there are five generally accepted states of sleep separate from consciousness. Stages 1 and 2 are light sleep whereas 3 and 4 are deeper, more restful states of sleep with lower brain metabolic rates and more cortical synchronization. Stage 5 or REM sleep is actually a very active stage of sleep with very high metabolic requirements rivaling that or exceeding wakefulness and its thought that REM sleep may be necessary for memory consolidation. The trick is that the architecture of sleep is broken up into various stages and you do not really approach the most intense REM periods until after you have progressed back and forth through some of the other stages including a more brief period of REM sleep earlier in the night. So, the most intense REM period is late into sleep and often early in the morning. If you short change yourself of the other sleep periods, you reduce the quantity and quality of your REM sleep period.

I've always wondered about the need for sleep. For an animal to allow itself to go into an extremely vulnerable state every day for hours it must have a VERY good reason for doing so. The fact that sleep has been passed along in our genes even in the face of natural selection (sorry creationist museum) shows this. I think we've barely penetrated the real reasons for sleep.

Re:Not good.....

[Golthur]

Not that I necessarily agree with this, but Carl Sagan hypothesized in Dragons of Eden that mammals were originally nocturnal, and evolved sleep so as to be still (and thus more difficult to spot) during the day when the reptiles (which dominated all niches when mammals first evolved) were active.

The fact that sleep has been passed along in our genes even in the face of natural selection (sorry creationist museum) shows this. I think we've barely penetrated the real reasons for sleep.

In fact, there are animals that don't appear to sleep, but actually do (dolphins, for example). What they do is sleep half their body and brain at a time. So there's obviously some benefit, as they've evolved the necessity to remain awake, but still get the sleep they need. (Unless it really happens to be some anomaly of evolution (another strike against creationism), like the appendix or spleen, that affects basically the entire population of living creatures). But I would think the dolphins proved otherwise, since they'd be the first to do away completely with sleep.

But a concern is still the long term side effects. By playing with stuff like this, would it lead to mental insanity later on due to paranoia or schizophrenia? We are, after all, playing with the mental state of mind (I'm sure tired muscles still remain tired even after popping the pills, even though the brain says it's fresh). The fact that the miliary trials concluded that it's only useful to about 48 hours wakefulness seems to imply that it doesn't reduce the need for sleep, just reduces the feelings of the need for sleep/sleepiness. We may end up with a population of zombies in a decade or two's time.

Anyhow, when did pill-popping become fashionable? I fear the day where it's "uncool" to not stick some drug in you as part of your daily routine in order to get through the day (as opposed to treating disease). Or the "there's a drug for everything" mentality.

Re:Not good.....

[BWJones]

Actually, you *are* a eukaryote and most of us posting here on Slashdot are with the exception of those that have foed me I suspect. :-)

Seriously though, worms, jellyfish and other "lower" invertebrates do exhibit periods of inactivity as do even prokaryotes such as bacteria. This period of "inactivity" is often crucial for normal physiological processes to occur. The important thing to note here is that through evolution, "higher" organisms appear to have accumulated a number of circadian clocks related to a variety of physiological functions and the "higher" up an organism is, the more clocks for various functions are accumulated.

Re:Not good.....

[Anonymous Coward]

, like the appendix or spleen

The appendix and spleen are NOT vestigial organs. While you can survive without them, your immune system is stronger if you keep them.

You can survive without your right arm, therefore it's vestigial, correct?

Statements like that (e.g., the appendix and spleen do not perform necessary functions) make evolutionists look stupid. Please research physiology before you try to prove evolution with misguided "facts."

And yet we snore, toss and turn, twitch, and sometimes talk in our sleep. Nothing says easy meal more than a loud unconscious mammal.

Re:Not good.....

[Frangible]

Exactly. Sleep-cheating drugs are nothing new-- look at methamphetamine. It's about 100 years old and is very effective, moreso than modafinil, for treating narcolepsy. People stay up for over two weeks with it (nevermind 48 hours!) but after a point an interesting thing happens where the brain hemispheres start taking turns shutting down and going into REM sleep. To the user, half their brain is dreaming and the other half awake, leading to an odd fused state of hallucinations that cannot be distinguished from reality. It's interesting to note this same behavior happens in some mammal (I don't recall which) that naturally does not sleep.

Beyond the acute effects though most mammals pushed through drugs like meth to avoid sleep simply die in studies after a month. The circadian cycle is needed for proper homeostasis. Sleep deprivation causes symptoms of ADHD (ironically, treated with stimulants), obesity via lower leptin and higher ghrelin levels, and a very nasty cycle of altered immune, inflammatory and glial response.

One other interesting thing to note is that the human circadian cycle specifically tracks dawn and dusk, via the CLOCK genes mPer1 and mPer2 -- mPer1 being dawn and mPer2 being dusk. If there is no gradual "dusk" period before sleep, direct changes in gene expression -- outside of sleep deprivation -- result in a persistently lowered level of tyrosine hydroxylase, interfering with dopamine levels. Dopamine is of course a neurotransmitter associated with motivation, goal seeking behavior, wakefulness, attention, etc. So therefore perish the dusk, perish the dopamine. And yet this commonly happens -- artificial lighting, computer / TV screens, etc right up to the moment of sleep destroy melatonin production and any sort of proper expression of mPer2 activity. Over time this results in low cortisol and catecholamine levels during the day (fatigue), higher levels at night (as the melatonin/hormonal peaks become disturbed), and increased hunger/activity during the missing dusk period, as you in essence train the natural oscillation to favor alertness at that time -- when it cannot be sustained.

Taking stimulants, be they modafinil, the neurotoxic ampakines, or amphetamine, only partially reverses some of these things. They increase neurotransmitter and cortisol levels -- but also do this when their levels should be lower! Chronic levels of cortisol alters body composition to favor muscle catabolism (breakdown), fat retention, annihilation of the thyroid hormone T3 into reverse T3 thus fucking up thermogenesis and the metabolism, and causing atrophy of the hippocampus and disruption of memory. This also results in suppression of the immune system, increased inflammatory response, increased stress/anxiety, etc etc.

Do any of these things sound like "happiness" you would take a pill for? Shut down the computer and TV, and artificial lighting sources at least an hour before bed. Relax, in dim light. Train yourself with a normal schedule in sync with the sun. You'll have greater alertness during the day, lower hunger, higher energy, better memory, and sleep better.

We are a nation of stimulus junkies, always wanting to be entertained by something novel, with no thought for relaxation, rest, or recovery. When our novelty seeking behaviors disrupts our normal diurnal behaviors, the answer isn't to take drugs and start the cycle anew, but to perform these behaviors in moderation and balance.

Try turning off your electronic shit a bit early tonight and relaxing before sleep at a normal, consistent time. In a week, you'll be surprised at the huge difference it makes.

We haven't heard from that guy in a while. Apparently, he was killed in a single-car accident at 4 a.m. on I-80 in central Nevada. Misjudged a curve due to a lack of depth perception while his left eye was sleeping.

Re:Not good.....

[jc42]

Uh birds sleep too.

Yeah, but there was the recent research showing that many birds sleep on just one side of their brain at a time. ;-)

One thing I thought interesting about the report was that some of their test subjects were cockatiels. We have 'tiels, and we've often seen them apparently asleep, but if you can move to see their other eye, you find it open and alert (while the first one is still closed). Apparently part of what triggered the research was people reporting this sort of thing in their pet birds.

The researchers instrumented the birds' brains (with very light-weight instruments ;-), and found that when the birds were in this state, with one eye open and one closed, their brain activity matched the pattern, with one hemisphere quiet and the other one active.

A curious aspect to this is that birds' eyes are, like ours, wired into both sides of the brain. But the "asleep on one side only" pattern exists, and matches the eyes.

The hypothesis is that birds generally don't need as much sleep as they get, so they stay half-alert to watch out for predators, maintain their grip on their perch, etc. And the alert side can send a wake-up signal to the sleeping side if anything interesting happens.

What are you talking about? Snoring is a defensive measure. Hell, it probably sounded like a large herd of vicious animals roaring when you put enough humans together snoring in unison.

And if that's not enough, I imagine that these early humans probably didn't do much in the way of bathing. Nothing says "I just tossed my lunch" than being downwind from a large pack of primitive humans.

Re:Not good.....

[Schmendr1ck]

A little bit of fact checking here:

1) We actually do know quite a bit about what the brain does during REM sleep, and there are several theories on why REM sleep is necessary. But yes, these are theories and we don't know for certain which one, if any, is correct.
2) I was unable to find any scientific evidence or reported cases of permanent psychological damage or death due to sleep deprivation, except in the case of an exceedingly rare biological disorder called Fatal Familial Insomnia. Of course, sleep deprivation can cause errors in judgment and reduced reaction time that can lead to death, but that wasn't what the parent meant.
3) The radio DJ the parent mentions was a guy named Peter Tripp. Yes, he did a publicity stunt where he stayed awake for about 10 days and hallucinated. However, he lost his job because he was caught accepting thousands of dollars in payola from the record companies. He more likely "faded into obscurity" because of the scandal. Shortly afterwards he got out of the radio business and into other careers where he was more successful.

This doesn't mean I disagree - I think drug-induced sleep deprivation has the potential for serious side effects and needs a heck of a lot more study before we all start taking our morning Modafinil. However, don't support a good argument with bad data. (Most of this info comes from Wikipedia - see Sleep Deprivation, Peter Tripp, and Fatal Familial Insomnia. All three entries appear to be well-referenced, feel free to spend an afternoon checking it out.)

[Warg! The Orcs!!]

I heard once in a psychology class (but have been unable to corroborate) that we too would be able to see in the UV range were it not for our lenses. The human eye lens is apparently slightly yellow and this filters out the UV. Patients who were given early artificial lenses reported being able to see new colours because the artificial lenses were clear.

The bugs! They are crawling up my legs!

But, sleep is where I'm a viking!

Don't worry, Taco! After 100 hours or so awake, you'll BE a viking, raping and pillaging and showing those pink elephants who's boss!

Re:The bugs! They are crawling up my legs!

[corychristison]

This reminds me of the time I tried to stay awake for as long as I could. I hit 93 hours or so. Note that this incident did not involve any drugs. Legal or otherwise.

I was still fairly young then, at the age of 14 or so. I was out with friends on the final night of my experiment and I started to see things and totally freaked out. One of the hallucinations was indeed a miniature pink elephant. As well I thought a tree was a very large spider. I have a terrible fear of spiders. After my friends managed to get me into the house and calmed me down, I suddenly got up and went out into the back yard to jump on the trampoline. It was -10 degree's Celsius or so and I was just wearing Jeans and a T-Shirt. I couldn't tell the difference. All I remember is having them waking me up and having to be rushed to the hospital. I was jumping on the trampoline and slipped. I flew off and cracked my head on a mound of ice. I'm just glad one of the springs didn't break or on the trampoline and hit me in the ass or something. It was fairly cold.

I stayed in the hospital for the night as the thought I may have had a concussion. I still don't remember any of that week. What I told you now is what my friends have told me. I also heard that earlier on in my experiment [first 24 hours I suppose] I had exclaimed to my friends that my toothpaste had started talking to me the next day at school.

Now I enjoy my sleep.

Pills? No thanks. I prefer the natural method of recovering from a hard days work writing code. :-)

The Only Profession Requiring No Sleep

[eldavojohn]

Doctor: Now, what seems to be the problem?
Patient: I got it bad, doc, I barely get any sleep ... I need some modafinil--or my life will fall apart!
Doctor: Now hold on there, I don't go around giving prescriptions of that to just anyone! You're young, you look like you're in good shape, why don't you get any sleep?
Patient: Well, it's just that ... I'm a ... software developer.
Doctor: My GOD! Why didn't you say anything? *yells out the door* Nurse! I'm going to need a lifetime's supply of modafinil--stat!
Patient: Oh thank you, doc, thank you so much!
Doctor: Everything's going to be alright, plus it seems your company's health care is willing to provide 100% of the funding for this with no deductable, can't say I've seen that before. Now you say that you're married as well? Then I'm going to recommend you take two of these every day with fifth of bourbon ...

The other flip side of a no-sleep drug

[inviolet]

So this pill will surely have some side-effects, and some of them will likely be negative. Fine.

Now think about the value of your time. You get ~100 years here on Earth and that's all. You are wired to spend about a third of that time unconscious. An entire third of your life will be spent not doing or experiencing anything.

How much effort do you expend just to shave ten minutes off your commute? Or to save three minutes standing in line?

What, then, would 33 extra years be worth?

As someone that has actually used Modafinil

[alexfeig]

I did sleep studies for a year. I was the guy that brought patients in, hooked up electrodes for brain activity, belts for breathing, electrodes on the legs for leg movement, etc -- then I sat in a small office staring at a computer screen for sometimes 12 hours on end watching them sleep making sure nothing went wrong, as well as making notes on potential sleep disorders. Apnea, Periodic Leg Movements, mainly. Obviously this job required that I work graveyards. After about 8 months on the job, my sleep schedule began to skip. I met my wife, I was trying to maintain a social life in the afternoons, etc. I started staying up when I got home until sometimes 2PM before going back to work at 8PM. Bad news. We obviously had a doctor on the staff, and he called us sleep techs into a room and we discussed the latest discoveries, etc. What came up was Modafinil. He mentioned that while he recommended Melatonin, Modafinil is approved for graveyard workers. Shortly thereafter I started taking Modafinil. I'll tell you, it works. Caffine is a terrible substitute. I used to drink so much coffee on top of caffine pills I OD'd more than once on it. Modafinil had 0 side effects (for me), other than the occasional slight bit of anxiety. It kept me awake, and it made me feel like I didn't even need sleep. When I'd get home, I could easily go to sleep because while it made you not FEEL like you didn't need to sleep, actually falling asleep wasn't difficult. When I would wake up I felt rested. I used Modafinil for about 4 months total -- and if I ever feel compelled to ruin my life with another graveyard shift, I'll be taking it up again. It's a marvellous drug.

The Horror - Watch Capitalism Adapt

[shambalagoon]

The true horror of this drug is that if it does become commonplace and people need less sleep, my bet is that capitalism will adapt itself to this new reality and we will soon be working 14-16 hour days.

Dont believe it? Look what happened as women entered the workplace in larger numbers in the last few decades (of course this is a good thing). As the number of workers increased, the relative incomes fell. When once a single worker could bring in enough money to support himself, his spouse, and his 2.5 kids, now it is almost necessary for both parents to work to be able to make ends meet. Think what it would be like if capitalism hadnt adapted to this influx of workers - each parent could work a 20-hour week and have the same relative income as 50 years ago.

Likewise, as waking time becomes less scarce, those willing and able to work longer hours will get the jobs and steadily raise the bar and the expectations of what's a normal amount to work each week. Maybe they'll get paid more and the increasing wealth will cause the cost of goods and services to rise, which increases the need for working the longer hours.

IANAE (I am not an Economist) so I'm probably wrong on some details, but this seems like a likely general trend, IMHO.

From a meth addict's perspective

[halo1982]

I'm 24 now and has been prescribed amphetamines and various stimulants since I was six years old due to ADHD. First Ritalin, then as a teen I moved onto adderall, and then about two years ago I discovered this wonderful (italics for emphasis on sarcasm) drug called methamphetamine. I thought it was great, I could go 48-72 hours programming and get more work than I ever thought possible done and then crash for 8 hours, repeat. This wears on you after a few weeks and I'd start sleeping 14 hours, then 24, etc. Eventually I just kinda went crazy, lost my job, etc. At first I don't think it was the euphoria the drug induces that made it so hard to quit, it was the productivity it induced. I became addicted to getting 6 days of work done in 2, and then it all kind of went down hill from there. I've been clean 277 days and half of the time thats just because I cut off contact with all the people I could get it from. This is not something you want to mess with. While I think "meth is bad" is pretty universal, you would be surprised how many software developers I bought/sold to for the exact same reason as I. And I live in a smaller city, I'd think this would be much more rampant in major areas such as LA, New York, Seattle.
Anyway the article this drug is about is Modafinil, also known as Provigil, a narcolepsy drug, which I've been prescribed for ADHD. And it does the same damn thing. Your body needs sleep, trust me I know, no matter what it is after two or three days your mind begins to break down. This drug certainly doesn't help with that, and if you RTFA (what are the chances of that?) the software developer in question mentions some of the things I pointed out. This worries me, greatly, because after going through a year of hell I'm now seeing articles like this discussing the potential for a "sleep-free" lifestyle, I have very little doubt in my mind that such a thing is not possible without great damage to the brain.

I am not everyman and I do have an extremely addictive personality, but I've seen friends who don't (have addictive personalities) fall into the same trap as I did under the allusion of "work more, work faster, sleep is for wimps!"
Anyway this is just my experience, but I thought I would share...

Need for sleep

[dargaud]

I read a paper in computational theory that went more or less like this. They proved via lambda calculus (the base maths of computational theory) that any sufficiently complex system needs a 'cleanup function'. In practical computer terms, it's the infamous garbage disposal process where lost pointers are dropped, unused pages are flushed from memory, seldom used memory commited to long term storage (mem to cache, cache to disk, disk to tape, etc...), data reorganised (in databases) or compressed, etc... During this period few, if any, real computing activity can continue; this translates as "if you don't reboot regularly, your computer will crash or you need a good garbage disposal process which will slow down your system for a while".

Now if you believe (like many) that the brain is no more than a big computing unit, then it must abides by those rules and the sleep is nothing else than the physical manifestation of 'garbage disposal'. Keep it up for too long and it will... crash.
