The longest time a human being has gone without sleep is a topic that has fascinated people for decades. In 1963, 17-year-old Randy Gardner broke the Guinness World Record by staying awake for 11 days and 24 to 264 hours. Gardner's record has been broken multiple times, with the current record holder, as of 1997, being Robert McDonald, who went 453 hours and 40 minutes (18 days and 21 hours) without sleep. Due to the health dangers of severe sleep loss, Guinness World Records no longer accepts new attempts for this category.

What You'll Learn
Randy Gardner's record
Randy Gardner, born around 1946, is an American from San Diego, California, who once held the record for the longest amount of time a human has gone without sleep.
Between December 1963 and January 1964, the then 17-year-old Gardner stayed awake for 11 days and 24 minutes (264.4 hours), breaking the previous record of 260 hours held by Tom Rounds. Gardner's record attempt was monitored by Stanford sleep researcher Dr. William C. Dement, and his health was supervised by Lt. Cmdr. John J. Ross. Two of Gardner's classmates from Point Loma High School, Bruce McAllister and Joe Marciano Jr., kept a log of the experiment.
During the experiment, Gardner experienced nausea and memory problems. However, on his final day, he appeared to be in excellent health and presided over a press conference, stating, "I wanted to prove that bad things didn't happen if you went without sleep." Gardner's sleep recovery was observed by sleep researchers, who noted changes in sleep structure during his post-deprivation recovery. After completing the experiment, he slept for 14 hours and 46 minutes, and then for an additional ten and a half hours the following night. Follow-up sleep recordings taken one, six, and ten weeks later showed no significant differences from his baseline.
Gardner's record was broken multiple times until 1997 when Guinness World Records ceased accepting new attempts for safety reasons. At that point, the record was held by Robert McDonald, who stayed awake for 18 days and 21 hours (453 hours and 40 minutes). Some sources also report that Gardner's record was broken a month later by Toimi Silvo, who stayed awake for 11 and a half days (276 hours) in February 1964.

Sleep deprivation effects
Sleep deprivation can have a wide range of negative effects on the body and mind, and these effects become more severe the longer a person goes without sleep. After 24 hours without sleep, people start to exhibit signs of impairment, similar to the effects of alcohol intoxication. Some of the initial symptoms of sleep deprivation include daytime sleepiness, nausea, and trouble with memory and concentration.
As sleep deprivation continues, more severe symptoms can develop, including "microsleeps" (momentary lapses into sleep that last a few seconds), uncontrollable eye movements (nystagmus), impaired judgment, impulsive behaviour, and visual and tactile hallucinations. Sleep deprivation can also negatively affect mental health, making it harder to manage and process emotions and increasing the likelihood of experiencing symptoms of depression and anxiety.
In the long term, sleep deficiency has been linked to various chronic health problems, including heart disease, kidney disease, high blood pressure, diabetes, stroke, obesity, and depression. It can also interfere with daily functioning, impacting work, school, driving, and social interactions. Sleep-deprived individuals may have trouble learning, focusing, and reacting, and they may struggle to judge other people's emotions and reactions.
It is important to note that attempting to go for long periods without sleep can be dangerous and potentially life-threatening. Guinness World Records no longer accepts attempts to break the sleep deprivation record due to safety concerns and the potential for serious health consequences.

Guinness World Records' policy change
Guinness World Records policy change
The Guinness World Records is a reference book that has been publishing world records across various categories since 1955. One such category was the longest time a human has gone without sleep. The record was set by Randy Gardner, who stayed awake for 11 days and 24 minutes (264.4 hours) between December 1963 and January 1964. He was 17 years old at the time. Gardner's record was broken multiple times until 1997, when Guinness World Records ceased accepting new attempts for safety reasons.
The decision to stop tracking sleep deprivation records was made due to the harmful and detrimental effects of sleeplessness on human health. Sleep deprivation can cause serious cognitive and behavioral changes, including moodiness, problems with concentration and short-term memory, paranoia, and hallucinations. It can also have long-term side effects, and in some cases, lead to death. Lab rats deprived of sleep die within a month, and people with the rare disease fatal familial insomnia (FFI) can also die within three months of losing the ability to sleep.
Craig Glenday, the Editor-in-Chief of Guinness World Records, acknowledged the importance of sleep as a fundamental part of human nature and recognized the dangers of sleep deprivation. He stated that challenging the extremes of something so absolute is key to understanding human nature.
As a result of this policy change, Guinness World Records no longer provides information about sleep deprivation records in its recent editions. The last Guinness World Record for sleep deprivation was awarded in 1986 to Robert McDonald, who stayed awake for 18 days and 21 hours (453 hours and 40 minutes). McDonald reportedly did not suffer any long-lasting negative effects and has continued to live a happy life.
While Guinness World Records no longer monitors sleep deprivation records, it is worth noting that the current record has not been broken for over 36 years, suggesting that the human limit for staying awake may indeed be around 19 days. However, the existence of microsleeps, or momentary lapses into sleep that are difficult to detect, makes it challenging to accurately determine the true upper limit of human wakefulness.

Robert McDonald's record
In 1986, Robert McDonald set a world record for staying awake for the longest period. McDonald went approximately 18 days and 21 hours (453 hours and 40 minutes) without sleep. This record has not been broken since.
McDonald's record came a decade after Randy Gardner's extensively documented 11-day sleep deprivation experiment. Gardner's record was broken multiple times until 1997 when Guinness World Records ceased accepting new attempts for safety reasons.
McDonald did not appear to suffer any long-lasting negative effects from his sleep deprivation. By all accounts, he has continued to live a happy life. He now has a son, Robert Jr., with whom he built a life-size replica Viking ship from 15 million ice-cream sticks in 2006.
Despite McDonald's apparent lack of ill effects, sleep deprivation is known to have harmful effects on the human body and mind. Even small amounts of missed sleep can negatively impact mental and physical health. The detrimental effects of sleep deprivation have been well-documented, with symptoms including irritability, impaired decision-making, cognitive rigidity, loss of motivation, higher blood pressure, paranoia, memory issues, mood changes, visual problems, hallucinations, and difficulties with speech.
Due to the potential health dangers of severe sleep loss, Guinness World Records no longer tracks sleep deprivation records.

Other record-breakers
While Randy Gardner holds the record for the longest period without sleep, there are several other notable mentions.
Firstly, in 1964, Robert McDonald went without sleep for 18 days, 21 hours and 40 minutes, totalling 453 hours and 40 minutes. This record was recognised by Guinness World Records until 1997 when they ceased accepting new attempts for safety reasons.
In 1964, Toimi Silvo from Hamina, Finland, reportedly stayed awake for 11 and a half days, or 276 hours, from February 5 to February 15.
In 1977, Maureen Weston from Peterborough, Cambridgeshire, England, set a Guinness World Record by staying awake for 449 hours during a rocking-chair marathon.
In 2007, Tony Wright attempted to break Randy Gardner's record and managed to stay awake for 266 hours. Wright spoke about the toll it took on his body and mind, highlighting the dangers of sleep deprivation.
In addition to these individuals, there have been other notable attempts at breaking the record for the longest time without sleep, including a 7-year-old boy from Kentucky, Wyatt Shaw, who fell asleep for 11 days in 2017, and a man from Austin, Texas, who drove home after a 3-night LAN party in his twenties and was saved by the cats' eyes in the road.
