The longest recorded time a human has ever gone without sleep is 18 days, 21 hours, and 40 minutes, which resulted in hallucinations, paranoia, etc. However most people can only last 4-6 days without stimulants, and about 7-10 days before the body will be unable to function and long term damage can be caused.
It all depends on the person, and what they do.
For example most people sleep everynight.
People who smoke Meth can go nearly a week without sleeping, maybe even longer.
I don't do any drugs and I can stay up for 2 days if I really want to.
There is no definite answer to your question. Humans can stay awake until the body can no longer handle it,
once your body can't take it any more, it will shut down in it's own way and there will be no choice but to sleep.
How long a person can stay up at a time depends on the person.
People often start feeling the effects of sleep deprivation by the 2nd and 3rd day.
By the fourth or fifth day people often suffer hallucinations.
11 days, or 264 hours, is the current record. The experiment was called off at that point.
After 96 hours of conciousness, the brain cells begin to die.
You can go for ever with out sleep. It would be difficult but it is possible.
No more than a week
3 days
Most people can survive for around 11 days without sleep, but extended periods of sleep deprivation can lead to serious health consequences such as cognitive impairment, mood swings, and even hallucinations. It is crucial to prioritize and maintain healthy sleep habits for overall well-being.
For as long as he/her can go without food, water, and sleep.
An elephant go without water for 24 hours;1 day
not that long
Different animals can survive without water for different periods of time. For example: A fish can not go very long at all without water but a camel can go a very long time without water. Humans can go without water for about 98 hours but after that they are almost dead.
Like breathing, sleep is a fundamental human requirement. It has even been said that one could survive for three times as long without food as one could without sleep. One of the better known experiments on this subject, found that depriving rats entirely of sleep resulted in their death, or near-dying state, within 11-32 days.
Perhaps, you didn't know, but humans need to sleep. I don't know how you are still alive if you didn't know about it. Humans usually sleep at night and do the rest at the midday.
Because you don't touch it and it goes to sleep. You can change how long it waits to go to sleep on the settings.
Years and years as many jungle tribes never went to a toilet
Humasn go to sleep because we get tired. Proper rest is part of a proper diet.
some animals that can survive the winter and not the summer go for long summer sleep.
I would say without irreversible health problems 10 days maximum.
