Randy Gardner ( record holder ) - wikipedia Randy Gardner ( record holder ) For other people named Randy Gardner, see Randy Gardner. Randy Gardner c. 1948 Occupation Record holder Known for Longest time without sleep Randy Gardner ( born c. 1948 ) is the holder of the scientifically documented record for the longest a human has gone without sleep. In 1964, Gardner, a high school student in San Diego, California, stayed awake for 264.4 hours ( 11 days 25 minutes ). This period of sleeplessness broke the previous record of 260 hours held by disk jockey Tom Rounds of Honolulu. Gardner 's record attempt was attended by Stanford sleep researcher Dr. William C. Dement. Gardner 's health was monitored by Lt. Cmdr. John J. Ross. A log was kept by two classmates from Point Loma High School, Bruce McAllister and Joe Marciano Jr. Accounts of Gardner 's sleep - deprivation experience and medical response became widely known among the sleep research community. Contents 1 Health effects 2 Recovery 3 Subsequent record information 4 See also 5 References 6 Further reading 7 External links Health effects It is often claimed that Gardner 's experiment demonstrated that extreme sleep deprivation has little effect, other than the mood changes associated with tiredness. This is primarily due to a report by researcher William Dement, who stated that on the tenth day of the experiment, Gardner had been, among other things, able to beat Dement at pinball. However, Lt. Cmdr. John J. Ross, who monitored his health, reported serious cognitive and behavioral changes. These included moodiness, problems with concentration and short term memory, paranoia, and hallucinations. On the eleventh day, when he was asked to subtract seven repeatedly, starting with 100, he stopped at 65. When asked why he had stopped, he replied that he had forgotten what he was doing. On his final day, Gardner presided over a press conference where he spoke without slurring or stumbling his words and in general appeared to be in excellent health. `` I wanted to prove that bad things did n't happen if you went without sleep, '' said Gardner. `` I thought, ' I can break that record and I do n't think it would be a negative experience. ' '' Recovery Gardner 's sleep recovery was observed by sleep researchers who noted changes in sleep structure during post-deprivation recovery. After completing his record, Gardner slept 14 hours and 40 minutes, awoke naturally around 8 : 40 p.m., and stayed awake until about 7 : 30 p.m. the next day, when he slept an additional ten and a half hours. Gardner appeared to have fully recovered from his loss of sleep, with follow up sleep recordings taken one, six, and ten weeks after the fact showing no significant differences. No long term psychological or physical effects have been observed. Subsequent record information According to news reports, Gardner 's record has been broken a number of times. Some of these cases are described below for comparison. Gardner 's case still stands out, however, because it is so extensively documented. It is difficult to determine the accuracy of a sleep deprivation period unless the participant is carefully observed to detect short microsleeps, which the participant might not even notice. Also, records for voluntary sleep deprivation are no longer kept by Guinness World Records for fear that participants will suffer ill effects. Some sources report that Gardner 's record was broken a month later by Toimi Soini, in Hamina, Finland, who stayed awake for 111⁄2 days, or 276 hours from February 5 - 15, 1964 and the Guinness World Records record is 449 hours by Maureen Weston, of Peterborough, Cambridgeshire in April, 1977 in a rocking - chair marathon. Because of the policy against maintaining this record, recent editions of Guinness do not provide any information about sleep deprivation. More recently, Tony Wright on May 25, 2007 was reported to have exceeded Randy Gardner 's feat in the apparent belief that Gardner 's record had not been beaten. He used 24 - hour video for documentation. The Australian National Sleep Research Project states the record for sleep deprivation is 18 days, 21 hours, 40 minutes.
