Duration of Sleep Avoidance: Impact of Sleep Deprivation on Human Physical and Mental Health
In 1964, a remarkable feat of sleep deprivation was achieved by a Californian high school student named Randy Gardner. At the tender age of 17, Gardner held the world record for staying awake without sleep, an astonishing duration of 264 hours, or 11 days and 25 minutes [1][2][4].
During this groundbreaking experiment, Gardner's mental state was meticulously monitored. After several days without rest, he began to experience concentration problems and short-term memory loss [2]. This underlines the significant impact that sleep deprivation can have on cognitive functions.
While there have been claims of longer durations, such as 453 hours (18 days, 21 hours, and 40 minutes) in 1986, these records are not officially recognised or widely verified like Gardner's [5]. In fact, Guinness World Records has ceased accepting attempts to break the sleep deprivation record due to safety concerns [2].
Thus, Randy Gardner's 11-day awake record remains the most credible and accepted duration for staying awake without sleep. This feat serves as a stark reminder of the importance of sleep for our overall health and wellbeing.
Sleep deprivation can have a host of short-term and long-term effects. In the short term, it can lead to drowsiness, reduced alertness, decreased concentration, impaired judgment, short-term memory problems, stress, and a higher risk of accidents [3]. After 72 hours without sleep, symptoms and fatigue intensify, causing extreme fatigue, difficulty multitasking, severe concentration and memory issues, paranoia, depressed mood, and difficulty communicating with others [3].
After 24 hours without sleep, cognitive function is impaired, reaction time is reduced, and the risk of accidents increases significantly. This is comparable to having a blood alcohol content (BAC) of 0.10 percent, which is illegal to drive with in the U.S. [3]
Chronic sleep deprivation can increase the risk of several health conditions, including obesity, diabetes, and heart disease [6]. It can also lead to symptoms such as fatigue, sleepiness, concentration difficulties, reduced coordination, irritability, increased appetite, mood changes, and reduced alertness [7].
In a 2015 study, two astronauts experienced impaired cognitive functioning, increased heart rate, and a reduction in positive emotions after staying awake for 72 hours [8]. Sleep deprivation can even be fatal in certain circumstances, such as causing dangerous accidents or through rare sleep disorders like fatal familial insomnia (FFI) [9].
To promote a better quality of sleep, it's essential to practice good sleep hygiene. This includes maintaining a consistent sleep schedule, winding down before bedtime, and avoiding caffeine in the evening [10]. The recommended sleep duration for adults between 18 and 60 years is at least 7 hours per night [11][12]. Adults should not stay awake for more than 17 hours to meet the CDC's sleep recommendation [11].
As we strive to balance our busy lives, let's not forget the importance of a good night's sleep. Randy Gardner's record serves as a warning of what can happen when we push our bodies too far, and a reminder of the importance of prioritising rest.
