Sleep is an essential human function, and going without it can have serious health consequences. Despite this, many people have attempted to go without sleep for as long as possible, with American Randy Gardner staying awake for 11 days and 24 to 25 minutes (or 264 hours) between December 1963 and January 1964, breaking a world record. Gardner's record has been beaten several times since, but Guinness World Records no longer accepts new attempts for safety reasons.

What You'll Learn
Randy Gardner holds the record
Gardner's record attempt was attended and monitored by Stanford sleep researcher Dr. William C. Dement, and Lt. Cmdr. John J. Ross of the US Navy Medical Neuropsychiatric Research Unit. Two of Gardner's classmates from Point Loma High School, Bruce McAllister and Joe Marciano Jr., kept a log of the experiment.
Physiological and cognitive tests began to reveal the negative effects of sleep deprivation on Gardner. After two days of zero sleep, his eyes struggled to focus, he showed signs of ataxia, and he found it difficult to identify objects based on touch alone. By day three, he became moody and uncoordinated, and by day five, he started to experience hallucinations. After breaking the record, Gardner slept for 14 hours and 46 minutes. He woke up naturally and felt groggy but not any more so than usual. He stayed awake until around 7:30 p.m. the next day, when he slept for an additional ten and a half hours.
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). Gardner's case remains notable due to its extensive documentation.

Sleep deprivation's negative health impact
Sleep is essential for maintaining physical and mental health. Sleep deprivation can have a negative impact on various body systems, organs, and processes. The effects of sleep deprivation can range from mild to severe and can accumulate over time. Here are some of the negative health impacts associated with sleep deprivation:
Mental Health and Cognitive Abilities:
Sleep deprivation can negatively affect your mental health and cognitive abilities. It can make it harder to manage and process emotions, leading to increased feelings of depression and anxiety. Sleep-deprived individuals may also experience impaired decision-making, creativity, and problem-solving skills. They may have trouble with learning, memory, focus, and reaction time. Prolonged sleep deprivation can even lead to hallucinations and trigger mania in people with bipolar mood disorder.
Cardiovascular System:
Chronic sleep deprivation can have long-term damaging effects on heart health and circulation. It increases the risk of developing high blood pressure (hypertension), high cholesterol (hyperlipidemia), and vascular disease, which can lead to an increased risk of stroke and heart attack.
Metabolic System:
Sleep deficiency can disrupt the body's metabolism and affect hormone regulation. It increases the risk of developing Type 2 diabetes and obesity. Sleep helps regulate the hormones that control hunger (ghrelin) and fullness (leptin). Lack of sleep can lead to higher levels of ghrelin and lower levels of leptin, making individuals feel hungrier than when they are well-rested.
Immune System:
Sleep is crucial for a healthy immune system. Sleep deprivation weakens the body's natural defenses, making it harder to fight off common infections and diseases. It can also increase the risk of developing certain cancers.
Nervous System:
Sleep deprivation can impact the central nervous system, which is responsible for sending and processing information in the body. It can increase pain sensitivity, making individuals more susceptible to pain.
The longest anyone has intentionally stayed awake without sleeping is a matter of some debate. Randy Gardner, a 17-year-old American, holds a well-documented record of staying awake for 11 days and 24 to 25 minutes (approximately 264 hours) between December 1963 and January 1964. However, there have been subsequent claims and records, some of which exceeded Gardner's feat, but Guinness World Records ceased accepting new attempts for safety reasons. It is important to note that sleep deprivation can have severe negative consequences, and attempting to break sleep deprivation records is strongly discouraged.

The difficulty of accurately measuring sleep deprivation
Determining how long someone has been awake without sleeping is challenging due to the possibility of undetected microsleep episodes. Microsleeps are brief periods of sleep that can occur without the individual's awareness, lasting from a fraction of a second to several seconds. These moments may be challenging to identify, especially if the person is not being carefully observed. Therefore, it is difficult to accurately measure sleep deprivation and determine the exact duration of wakefulness.
The accuracy of self-reported sleep duration is questionable, as individuals might not be aware of microsleep episodes or may unintentionally underestimate their sleep duration. Additionally, factors such as caffeine consumption or other stimulants can mask the symptoms of sleep deprivation, making it harder to assess the actual level of wakefulness.
Furthermore, the measurement of sleep deprivation is not just about the number of hours spent awake but also includes evaluating cognitive and physiological changes. Sleep deprivation can cause moodiness, lack of coordination, hallucinations, and difficulties with memory and focus. These symptoms can vary among individuals, making it challenging to establish a standardized metric for assessing the effects of sleep deprivation.
The potential health risks associated with severe sleep loss have led organizations like the Guinness World Records to discontinue accepting records for voluntary sleep deprivation. This decision underscores the recognition of the harmful consequences of sleep deprivation, which can include fatal insomnia and increased risk of stroke.
The current record for the longest period without sleep is attributed to Randy Gardner, who stayed awake for 11 days and 24 to 25 minutes (approximately 264 hours) in 1963-1964 when he was 17 years old. While Gardner's record-breaking attempt was extensively monitored and documented, subsequent attempts to break this record may not have received similar scrutiny, making it challenging to accurately measure and validate claims of extended sleep deprivation.

Sleep deprivation records no longer kept by Guinness World Records
The record for the longest time without sleep is held by Randy Gardner, who stayed awake for 11 days and 24 to 25 minutes (264.4 hours) from December 1963 to January 1964. He was just 16 or 17 years old at the time. Gardner's record was then broken multiple times until 1997, when Guinness World Records ceased accepting new attempts for safety reasons. The last person to hold the Guinness World Record before the category was removed in 1989 was Robert McDonald, who stayed awake for 453 hours and 40 minutes (18 days and 21 hours).
Randy Gardner's record attempt was carefully observed and well-documented. He appeared to be in excellent health, and after completing his record, he slept for 14 hours and 46 minutes. However, he reported experiencing serious insomnia around 2007, decades after his sleep experiment, and believed his participation in the 1960s sleep study was a contributing factor.
Due to the potential health dangers of severe sleep loss, the Guinness Book of World Records has stopped listing records for voluntary sleep deprivation. They no longer acknowledge sleep deprivation attempts or responds to attempted records of sleep deprivation as they feel they are too dangerous and could cause participants to suffer ill effects.

Other sleep-related world records
While Randy Gardner holds the record for the longest period without sleep, there are several other sleep-related world records.
Firstly, the record for the longest recorded dream in terms of REM sleep duration was set by David Powell in 1994. During a sleep study, Powell experienced a REM phase that lasted 3 hours and 8 minutes, which is recognised as the longest REM cycle recorded in a lab setting.
Another unique record is held by Ben Burfoot of the UK, who completed the Virgin Money London Marathon in 2019 in a sleeping bag, with a time of 3 hours, 41 minutes, and 59 seconds.
In addition, Maureen Weston of Peterborough, Cambridgeshire, holds a sleep-related world record. In 1977, she stayed awake for 449 hours during a rocking-chair marathon, breaking Randy Gardner's record.
Other notable mentions include the world's largest sleepover, the fastest time to fall asleep on stage, and the longest line of human-mattress dominoes. These records showcase the fascinating and quirky world of sleep-related achievements.
