Sleep is essential for human survival, and while it may not directly cause death, sleep deprivation can increase the risk of morbidity and mortality in several ways. The effects of sleep loss are progressive, and after a night or two without sleep, individuals may experience irritability, cognitive impairment, and weakened immunity. Prolonged sleep deprivation can lead to severe physical and mental symptoms, including hallucinations, paranoia, and an increased risk of accidents and injuries. Additionally, there are rare genetic disorders, such as fatal familial insomnia, where death can result from a lack of sleep. Understanding the impact of sleep deprivation is crucial, as it can indirectly contribute to premature death by increasing the risk of various health conditions and accidents.

What You'll Learn
Sleep deprivation psychosis
Sleep is essential for both the body and the mind. Going without sleep can have nasty side effects, and chronic sleep deprivation can even lead to death, although this is rare.
The early effects of sleep deprivation psychosis include irritability, anxiety, and a sense of being disconnected from your thoughts and feelings. After 48 hours without sleep, more severe symptoms, including hallucinations and an inability to think clearly, will likely occur. The longer you are deprived of sleep, the greater your risk becomes for severe, long-lasting effects of sleep deprivation psychosis.
The symptoms of sleep deprivation psychosis include:
- Auditory and visual hallucinations (hearing or seeing things that aren't there)
- Delusions (believing things that clearly have no basis in reality)
- Depersonalization (feeling detached from your thoughts and emotions)
- Derealization (feeling detached from your surroundings)
- Disordered thinking, which can include problems forming logical thought patterns or maintaining a clear train of thought
- Inability to speak in a manner that is logical and understandable
- Severely disorganized behaviour, which can include behaviour that is unusual or unexpected for a given situation, or could refer to sudden agitation

Increased risk of accidents
Sleep deprivation can have serious consequences, and can even be life-threatening. While it is rare to die from a lack of sleep, chronic sleep deprivation can contribute to an early death by increasing the risk of accidents, injuries, and chronic health conditions.
One of the most significant risks associated with sleep deprivation is the increased likelihood of accidents and injuries. Studies have shown that getting less than seven hours of sleep over a 24-hour period significantly increases the risk of being involved in a car accident. Operating heavy machinery or driving a car while sleep-deprived can be extremely dangerous, as reaction times are slowed and cognitive function is impaired. This can lead to poor decision-making and increased risk-taking behaviour, which can have fatal consequences.
In addition to car accidents, sleep deprivation can also increase the risk of other types of accidents and injuries. For example, individuals experiencing sleep deprivation may be more prone to falls or other accidental injuries due to decreased coordination, balance, and concentration. They may also be more likely to engage in risky behaviours or activities that can result in harm.
Furthermore, sleep deprivation can also increase the risk of accidents and injuries by exacerbating existing health conditions. For instance, individuals with heart disease, lung disease, or diabetes may find that their symptoms worsen due to a lack of sleep, increasing the likelihood of a health crisis. Sleep deprivation can also trigger seizures in individuals with epilepsy, which can be life-threatening, especially during sleep when emergency medical response may be delayed.
The effects of sleep deprivation on the body and mind can significantly increase the chances of accidents and injuries, highlighting the importance of adequate sleep for overall health and safety. While it may not directly cause death, the indirect consequences of sleep deprivation can be severe and even life-threatening. Therefore, it is crucial to prioritize healthy sleep habits and seek professional help if struggling with sleep deprivation or sleep disorders.

Negative health consequences
While it is rare, chronic sleep deprivation can lead to death. Sleep is essential for maintaining good health, and not getting enough sleep can have nasty side effects.
After 48 hours without sleep, you will experience physical and mental symptoms, including a foggy head, difficulty concentrating, irritability, and a weakened immune system. After three days, things get worse: you may experience extreme exhaustion, a racing heart, mood changes, and problems with emotional regulation. You may also find it difficult to focus on conversations, work, or even your own thoughts.
Prolonged and recurrent sleep deprivation has serious additional health consequences that are associated with an increased risk of death. For example, it increases your risk of diabetes, heart disease, and weight gain, which in turn increases your risk of cardiovascular disease, stroke, and some cancers. Sleep deprivation also increases your risk of accidents and injuries, which can be life-threatening.
In addition, sleep deprivation can induce ROS accumulation and oxidative stress in the gut, which can eventually trigger cell death. This has been observed in mice and flies, and similar oxidative processes may occur in the human gut during chronic sleep deprivation.

Intestinal ROS accumulation
The intestine is composed of many distinct cell types that respond to commensal microbiota or pathogens with immune tolerance and pro-inflammatory signals, respectively. Reactive oxygen species (ROS) are essential in maintaining normal intestinal physiology. ROS produced by mucosa-resident cells or by newly recruited innate immune cells are essential for antimicrobial responses and the regulation of signalling pathways, including processes involved in wound healing.
Impaired ROS production due to inactivating patient variants in genes encoding NADPH oxidases as an ROS source has been associated with Crohn's disease and pancolitis. Overproduction of ROS due to up-regulation of oxidases or altered mitochondrial function was linked to ileitis and ulcerative colitis. Maintaining a redox balance is crucial to preserving gut homeostasis.
Deregulation of the mitochondrial electron transport chain (mETC), with increased mitochondrial ROS (mtROS) levels, was observed in inflammatory bowel disease (IBD) patients, and decreasing mtROS ameliorated colitis. Tightly controlled ROS generation by enzymes expressed in non-phagocytic cells, for example, enterocytes or fibroblasts, is essential. Low physiological levels of ROS are indispensable for a variety of signalling pathways, including gene transcription, protein kinase activation, and phosphatase inhibition, thereby regulating cytokine production and coordinated cell motility.
The importance of maintaining physiological levels of ROS in the gut is highlighted by the chronic intestinal inflammation present in patients with inactivating gene defects in NADPH oxidase. Intestinal oxidative stress depends on the balance of ROS. Excess ROS are widely implicated in intestinal inflammation and cancer.

Microsleeps
The dangers of microsleep are not limited to driving. In the medical field, for example, studies have shown that needlesticks and injuries with sharp instruments occur more frequently during night shifts or extended work hours when medical workers are more likely to experience microsleeps. Similarly, a microsleep episode was recorded as a factor in the 2016 Croydon tram derailment, highlighting the potential consequences for public safety when certain workers experience microsleeps.
While microsleep episodes themselves are not dangerous, they can lead to incidents resulting from a lack of awareness. The risk associated with microsleeps depends on the environment and the potential consequences of losing awareness momentarily. For example, microsleeps while driving or operating machinery can be life-threatening, while microsleeps on a couch at home are unlikely to cause harm.
To minimise the occurrence of microsleeps, it is important to address sleep deprivation and improve sleep habits. This may include planning for 8 hours in bed, which typically results in 7 hours of sleep for most adults. Additionally, taking short breaks, power naps, and consuming caffeine can help reduce drowsiness and the likelihood of microsleeps in the short term.
