How long can the human body can go without sleep?

Answer 1

sorry last person waffled too much and didn't answer your question properly

The record for the longest period without sleep is 18 days, 21 hours, 40 minutes during a rocking chair marathon. The record holder reported hallucinations, paranoia, blurred vision, slurred speech and memory and concentration lapses.

One of the most common questions about sleeping is that, "Do we actually need sleep?" The answer is yes, although our bodies can be trained to do with gradually less sleep. There may be some people who claim that they need no sleep at all, but you will find that they tend to take occasional five to ten-minute naps during the day. We need sleep for our body to relieve stress, to grow, and also to balance our bodily chemicals.

Around the beginning of the century it was thought that chemicals such as lactic acid, carbon dioxide, and cholesterol were collected in our brain while we were awake and were depleted during sleep. But about sixty years later we began experimenting on how long a human body could go without sleeping. Randy Gardner, a 17-year-old high-school student from San Diego, stayed awake for eleven complete days. Although he felt nauseous at times, had difficulty reading, and suffered temporary memory lapses, he had no long term emotional or physical side-affects of the experiment. Measurements have been taken, however, to prove that there are some chemical changes during sleep deprivation that concludes the fact that our body needs sleep.

There was a study done during ww2 you can find it on the net, and it is some strange stuff about how people were forced to stay awake. but it all depends on the person i.e. age, weight, how much they have to eat drink ect. any numbr of things to take into consideration. but your body will shut down and make you sleep.
