In December 1963/January 1964, 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 attended by Stanford sleep researcher Dr. William C.
For a healthy person, there is unlikely to be long-term health consequences from a single all-nighter. “I think about sleep deprivation as a physiological earthquake,” Simon says. “If it's a relatively rare event… the body can recover after a couple of days."
