CWI, I remember you once had posted some time back about sleeping experiements you were working on. I wanted to read it again and tried retrieving it from the other now defunct place without success. By any chance do you have a copy of it or just maybe someone else does?

What I want to see again is CWI's thread about his life experiences. I can't remember the thread title but it was about significant events in your life, and how they make you who you are.

I would like to see both of these. I have way to much experience with sleep deprivation and school and working night shifts in the spital.

Parenthood is good for inducing sleep deprivation. So is stress. I never saw anything about experiments, though, so if there's a link, I'd be interested.

It involved him testing himself on going without sleep for x amount of time and his mindset and other observations about himself under those conditions. |

Some dogs are better left sleeping. It helped me put it behind me to get those experience's out. Those are thoughts and places I'd rather not go back to. I've been able to sleep most nights since then, so I intend to let those dogs keep sleeping.
The sleep deprivation was not an experiment. It was yearly training. 5 days was my typical max before delusions and micro sleeps were a problem.
In my specific case, I would hear things on that 5th day that were not there. Everyone has a max time they can go without sleep before it begins to significantly reduce their mental capacity to function. Timing and reflexes begin to be affected in the first 24 hours, and severely so within the first 48 for most people. Some can go upwards of 4 days without dangerous effects.
By dangerous I mean falling asleep standing, severely impaired vision, motor skills, short term memory losses etc.
Eventually the person will begin to experience delusions the nature of which is subject to the individual.
It has always been my position that you must test your gear in a controlled environment before it test you in an uncontrolled environment. The most important piece of gear you have is your brain.
You must know your limits. If you know that in 3 days of sleep deprivation you will begin to flip out, then you know to get some rest somewhere before it causes a problem.
Forgeting your BOB, your rifle, or shooting at noises or apparitions, all not good for survival. Unless the person has been in spec ops training, most don't know what their limits are, nor the importance of them.

I know I'm good for the first 68 - 70 hours, but after that, I have no experience. That experience involved typing coherently (not just correct characters, but making sense in what I'd written), driving safely, and remaining functional until I was free to sleep. I have not tested myself past that point. There were no delusions, no naps, just a focus on completing the task at hand. Nevertheless, I wouldn't wish to repeat the situation. This took place while I was in college and I'm more than twice that age now, so it's logical that my endurance would have diminished. Life & death situations change everything, though, so it might be a good idea to test myself once school is out... minus the driving part.
This is one area that I hadn't thought about testing for survival purposes. The concept of guard duty and taking shifts was there, but the what-if aspect of having to cover extra hours hadn't really dawned on me.

Sorry cwi, I didn't mean to open a can of worms and rehash bad memories long put behind you. You did answer my question, thankyou very much, in regards to the sleep training and your observations. I agree it is good training and much food for thought to consider it's benefits if the need arises to subject oneself to lengthy spans of sleep deprivation, especially for unforeseen circumstances requiring you to do just that. Everyone should have an idea of their limitations without jeopardizing a situtation due to mental or physical fatigue. This should be a priority on everyone's preparedness list!  |

I strongly advise having a partner/friend help you if you test this. For obvious reasons, you won't be thinking right towards the end of it, you need a rested partner to externally judge when its time to call a stop to it.

For obvious reasons, you won't be thinking right towards the end of it, you need a rested partner to externally judge when its time to call a stop to it. Yes, that is a very important factor to mention. Ordinarily I don't nap in the daytime. For the past few months on occassion I have done some micro sleeping and that's what reminded me of that older thread. Just that little boost gets me far for the rest of the day until nightfall. I can see where micro sleeping would benefit me in tight situations until I'm afforded longer resting. Of course the body would eventually limit oneself to so many micro sleeps until it's extended to several hours of non-stop sleep. |

CWI, didn't intend to bring up bad memories. Just thought there was some thought provoking material in there that really made me think. Those dogs can lay in peace as long as you are sleeping well. Blessings, mark

I'm good without sleep for 24-36. Then I start to get really cranky. That's my 1st sign of deprivation issues.
I have a high metabolism and eat constantly. I get irritable after 12 hours without something in my stomach. Fortunately caffiene (tea/coffee) calms the stomach. So I have lots of Tea bags in my gear.

when i was a teen i suffered from severe insomnia (stress related) and the longest i went without sleep was 7 days, i dont realy remeber the last 3 as i was delirious apparently and had to be put into a chemical sleep as my brain just wouldnt shut down
i suffered less and less with it as time went on but even now i can go 2-3 days with no sleep and feel no major effects, i dont like to do it as i regulate my sleep very closely (one way to overcome insomnia) and going without makes me irritable but i dont sleep 8 hours at a time like most people, i tend to sleep 3-4 hours in every 12 hour period (i just cant sleep for 7-8 hours straight)
apparently what i do is called a paleo sleep system as most paleobiologists agree that this is how our hunter gatherer ancestors would sleep

I know that I suck without sleep. I am a natural night owl....so being up all night is no problem for me. I frequently play intense poker games for lots of money until 4:00 or 5:00 a.m. and I'm completely alert and focused and when it's all over it takes me a good 2-3 hours just to unwind so that I CAN fall asleep. But then I sleep and I sleep good and deep.
A few times I've had to keep going strong all day after incidents where I stay up all night and it turns ugly in a hurry. Usually at about 38-40 hours of being awake I become a danger to myself and others. Hallucinations (like seeing a moving cartoon when it's really just a tree.....) Incoherent speech. Delusions of persecution (paranoia). Extremely dangerous behind the wheel of a car (and we're talking absolutely no alcohol or substance abuse....just by lack of sleep I'm 10x worse than a drunk driver!!).
I've deduced that I would be a pretty valuable "night watch" group member, but I'd need a guarantee that I could sleep AT LEAST 6 hours in a row every 24 hours.

When I was young and had to stay up for extended periods I found 1/2 hour cat naps every four hours and I could go for a about 5 days before I started to have problems. I used to have the ability, some kind of internal alarm clock, I could decide to sleep for a period of time and I would wake up within a few minutes of the time. I also had the ability to go to sleep almost immediately, anywhere, any time of day or night, noise or not it just didn't matter. Now I can't sleep half the time and when I do sleep its a 50/50 chance I will wake up to an alarm. Its hell to get old. |
