How long can a human being survive without sleep?

 

Sleep is a crucial aspect of human health and well-being, and the exact amount of time that a person can survive without sleep varies depending on the individual. However, most adults require an average of 7-9 hours of sleep per night to function properly.

Studies have shown that complete sleep deprivation (going without sleep for several days) can have serious negative effects on both physical and mental health. In some extreme cases, sleep deprivation has resulted in death.

The longest recorded period without sleep is 11 days, achieved by a man named Randy Gardner in 1964 as part of a science fair experiment. However, it's important to note that this type of prolonged sleep deprivation is not recommended and can have serious negative consequences on a person's health and well-being.

Even short-term sleep deprivation can have negative effects on the body, such as impairing cognitive function, reducing immune function, and increasing the risk of accidents and injuries. It's important to prioritize getting enough sleep for optimal health and well-being.
