Sleep is a basic human need, just like eating and drinking, and is vital for our health and well-being. Sleep deprivation can have severe consequences on our health, and the longer we go without sleep, the more intense the side effects become. After 24 hours without sleep, stress hormones such as cortisol and adrenaline increase, causing fatigue, irritability, and difficulty concentrating. After 36 hours, these symptoms worsen, and by 72 hours, our ability to regulate our emotions and perceive the world around us is severely compromised. Going without sleep for 96 hours (4 days) will likely have serious physical and mental health consequences, and may even result in death.

What You'll Learn
Hallucinations and distorted reality
Sleep is one of our most basic bodily functions, and it plays a vital role in our physical, cognitive, and mental well-being. While the exact reasons why we sleep are still unknown, we do know that restorative processes occur during sleep that are necessary for our health.
Sleep deprivation can have serious negative effects on the body and mind, and it can even be dangerous to go without sleep for just one day. After 24 hours of no sleep, stress hormones like cortisol and adrenaline increase, causing cognitive impairment similar to that of someone with a blood alcohol content of 0.1%. This can lead to reduced reaction time, slurred speech, and slowed thinking.
As sleep deprivation continues, these symptoms worsen, and new ones may emerge. After two days without sleep, individuals can expect increased irritability, anxiety, foggy memory, impaired thinking, and possible hallucinations. Some people may also experience mood swings, with some feeling depressed and others euphoric.
After three days without sleep, the urge to sleep will strengthen and may become uncontrollable. Microsleeps, which are brief periods of sleep that usually last a few seconds, may start to occur. Perception becomes severely impaired, and hallucinations may become more complex. Individuals may start to see, hear, or feel things that aren't actually there. Visual phenomena may include simple percepts, such as flashes, lights, and dots, as well as complex hallucinations. Auditory hallucinations may also occur.
After four days without sleep, the distortion of reality becomes even more severe, resembling acute psychosis. The urge for sleep will be unbearable, and individuals will experience frequent and longer microsleeps. Hallucinations will likely continue and may become more intense and persistent.
It is important to note that the effects of sleep deprivation can vary, and some individuals may experience hallucinations earlier or later than the timelines mentioned above. Additionally, while dying from sleep deprivation is rare, it is possible. Therefore, it is crucial to prioritize sleep hygiene and seek professional help if you are struggling with sleep deprivation or insomnia.

After 24 hours without sleep, an individual may experience cognitive impairment similar to that caused by alcohol intoxication. This can include reduced reaction time, slurred speech, and slowed thinking. They may also develop anxiety, irritability, and daytime sleepiness.

Emotional dysregulation
Sleep is necessary to keep our central nervous system functioning properly. However, going without sleep for 4 days can have severe consequences on emotional regulation.
After 24 hours of no sleep, the stress hormones cortisol and adrenaline increase to compensate for the fatigue you're battling and help you function. As your body keeps pumping cortisol into your bloodstream, raising your heart rate and blood pressure to keep you alert, the additional stress can increase feelings of anxiety and mood swings. If you were cranky, on edge, and zombie-like before, those symptoms will likely worsen after 36 hours with no sleep.
At 48 hours and beyond without sleep, you may develop depersonalization and derealization, causing problems with perceiving yourself and reality. You may also experience auditory and complex visual hallucinations, such as thinking you hear a dog barking or seeing fully formed images. These symptoms can cause severe emotional distress, as you struggle to differentiate between what is real and what isn't.
Additionally, sleep deprivation can negatively impact your ability to manage and process your emotions. It can make you more prone to mood changes, irritability, and emotional dysregulation. You may find yourself experiencing increased negative emotional responses to stressors and decreased positive emotions. This can further compromise your decision-making processes and creativity.
Microsleeps also increase in length and frequency at this level of sleep deprivation. These are fleeting moments of involuntary rest that can be incredibly dangerous, especially if you're driving or operating heavy machinery.
Overall, going without sleep for 4 days can have severe consequences on emotional regulation, leading to increased stress, anxiety, mood swings, hallucinations, and emotional distress.

Physical health consequences
Sleep is vital for health, and experts recommend that adults get at least seven hours of sleep every day. Sleep plays a crucial role in our physical, cognitive, and mental well-being. While a few people have managed to go as long as 11 days without sleep, this is not a common or safe practice. The longer one goes without sleep, the more severe the effects.
After 24 hours without sleep, stress hormones like cortisol and adrenaline increase to compensate for fatigue and help the body stay activated. This leads to symptoms such as anxiety, irritability, daytime sleepiness, reduced reaction time, slurred speech, and slowed thinking. The cognitive impairment at this stage is comparable to having a blood alcohol content of 0.1%, which exceeds the legal driving limit in most places.
After two days without sleep, symptoms intensify and include increased irritability, anxiety, foggy memory, impaired thinking, and possible hallucinations. The individual may feel depressed or euphoric, with significant deficits in concentration, motivation, perception, and other higher mental processes.
By the third day, the urge to sleep strengthens and may become uncontrollable. Microsleeps, which are brief periods of unintentional sleep, become more frequent and longer. Hallucinations, illusions, and delusions may occur, and the individual's perception of reality may be severely distorted, resembling acute psychosis.
After four days without sleep, an individual may begin to experience slurred speech or unsteady walking. Hallucinations become increasingly complex and frequent. As people approach the 120-hour mark, they may experience a rapid and severe decline in mental health, with symptoms of psychosis, complex delusions, and violent behavior.
