How many days can a human being live without sleep?

There is no single definitive answer to this question as it depends on various factors such as the individual's health, age, and overall well-being. However, most experts agree that the average person can go without sleep for approximately 3-4 days before experiencing significant cognitive and physiological impairments. Beyond this point, the body begins to shut down and the risk of serious health problems increases.

Some individuals have reported staying awake for longer periods of time, but these cases are rare and often involve the use of stimulants or other artificial means of staying awake. In general, it is not advisable to go without sleep for extended periods of time as it can have serious consequences for one's health and well-being.
