Sleep deprivation is a state where a person does not get enough sleep, either for a short period or over a long time, and it has well-documented effects on the brain and body in scientific literature. Sleep is critical for cognitive processing, emotional regulation, and sensory integration, and when it is reduced or disrupted, normal brain signaling begins to break down. One of the most common causes of sleep deprivation is insomnia, a disorder defined by persistent difficulty falling asleep, staying asleep, or getting restorative sleep despite having adequate opportunity. Chronic insomnia is associated with increased risk of anxiety, depression, cardiovascular disease, and long-term cognitive impairment. Stress, irregular sleep schedules, shift work, psychiatric conditions, and stimulant use are frequently reported contributing factors. As sleep loss accumulates, the brain’s ability to accurately interpret sensory information becomes impaired. Research shows that after approximately 24 to 72 hours of sustained sleep deprivation, individuals may begin to experience perceptual disturbances and hallucinations. These can include visual distortions such as shadows, flashes of light, or movement in peripheral vision, auditory phenomena like hearing voices or sounds, and tactile sensations such as tingling or the feeling of something crawling on the skin. These experiences occur because sleep deprivation disrupts communication between the thalamus and cortex, causing internally generated signals to be misinterpreted as external stimuli. Cognitive performance declines significantly during sleep deprivation. Attention span shortens, reaction time slows, working memory becomes unreliable, and decision-making is impaired. Emotional regulation is also affected, leading to increased irritability, emotional instability, heightened stress responses, and reduced impulse control. Neuroimaging and neurochemical studies suggest that these effects are linked to altered dopamine signaling and reduced activity in the prefrontal cortex, a region essential for reality monitoring and executive function. Severe or prolonged sleep deprivation can produce symptoms that resemble psychotic disorders, including paranoia, dissociation, and complex hallucinations. However, research consistently indicates that these symptoms are often reversible once normal sleep is restored, distinguishing sleep-loss-induced hallucinations from primary psychiatric conditions. Treatment and prevention strategies described in the medical literature emphasize non-pharmacological approaches such as cognitive behavioral therapy for insomnia (CBT-I), regular sleep-wake schedules, circadian rhythm stabilization, and sleep hygiene practices. In some cases, short-term pharmacological interventions are used under medical supervision. Restoring sufficient, consistent sleep is shown to normalize neural activity and reduce perceptual and cognitive disturbances #sleep #pov #relatable #insomnia #fyp credit @/ tonylisenkoo
