I was with the Army and had to go 36 hrs without sleep while keeping watch on a suspected terrorist house (I won't say where).\nBut it was the worst time of my career - and it was the wrong house!

Lack of sleep is one cause.

In 1965 Randy Gardner broke the record for consecutive sleeplessness. He stayed awake for 11 days in a row without sleeping and made it into the Guinness Book of Records.\n\nThe longest lethargic sleep incident is mentioned in the Guinness Book of Records. It happened to Nadezhda Lebedina (born in 1920 in Russia's Dnepropetrovsk region). The woman had a very big argument with her husband in 1954 and fell asleep because of the stress for 20 years. Nadezhda recovered only in 1974: doctors concluded that she was an absolutely healthy individual.

I have fallen asleep at school before.  I fell asleep on guard duty once when I was in the Army.  Thank God I was not in combat.  And I have been in that zone in / out state while at my present location.

I have a friend who once stayed up for 4 consecutive nights. By the end of it, he was in pretty bad shape.

Cruel experiments on mice were done decades ago where the mice were kept awake and died after 23 days. The muscles just can't take it, the heart cannot keep up. In sleep the heart slows and less stress on the diaphram. In humans severe mental illness can be caused by no sleep. In fact, there have been cases of people having halucinations due to severe sleep deprivation. But it is not believed that a person would die like mice from no sleep. Ordinarily a person would just sleep where they stand if it came down to it, or collapse on the floor, wherever they are.

when I was younger I also had problems sleeping, my Mother bought a tape of the ocean, like the waves coming in, and I still use that same tape today.  It takes me at most 20 mins to pass out.

I was once caught alone in a snowstorm on a glacier in the Beartooth mountains in Montana.  After spending a long night\nin a makeshift shelter I tried to hike out the next day using map and compass with visibility about 10 feet.  At one point  I climbed quite high on the glacier and stopped to survey the situation.  When I put my hand back to prop myself up--\nnothing there!  I was at the top of a cornice at the edge of a 300 foot cliff.   Never been so scared in my life.  My heart didn't stop pounding for 20 minutes.

I went almost a week with only a couple 30 minute naps.  It depends on who you are and how much energy inducing stuff you drink normally.

This is an interesting one which I think depends on what we THINK we need. Most folk in UK seem to generally consider we need 8 hours or thereabouts. I joined a group once which stated that if you needed more than 4 hours there was something the matter with you. This struck me as quite ridiculous on first hearing it but I gradually realised that our perception and conditioning are an enormous influence. I now KNOW I can manage quite well with 5 or 4 hours but have the capacity to sleep for 12 hours too. I am truly blessed to be able to drop off almost the minute my head touches the pillow.

Indefinitely.  I'm not sure what the record is, but people have remained comatose for many years.

Ive heard that the average human being can go without food as long as they still have water for a full month.  I've personally gone 2 weeks without food.  Just to see.  Then I got so hungry that I got sick.  And I had to eat.  But at least I know what my limit is now!
