A study on the effects of 24 hours of sleep deprivation in young healthy adults revealed significant disruptions in emotional, cognitive, and physiological responses. Participants exhibited heightened negative emotions such as anxiety and depression, decreased cortisol levels, and increased inflammatory…
Scientists propose the Mind After Midnight hypothesis, arguing that the brain shifts into a markedly different mode when we stay awake after the biological night begins. During these hours, attention fixes more easily on threats, mood tilts negative and the…
The relationship between sleep and recovery from exercise-induced muscle injuries, with a focus on athletes and military personnel. Insufficient sleep combined with high training loads increases the risk of muscle injuries. Adequate sleep enhances muscle repair by regulating hormonal and…
A study on female university students found that poor sleep efficiency and frequent daytime naps significantly increase the risk of depersonalization disorder. Sleep efficiency improvements were linked to reduced depersonalization symptoms, while more frequent naps tripled the risk. No significant…
A study comparing sleep deprivation and alcohol on driving performance found that 24 hours of wakefulness impairs drivers more than being slightly above the legal alcohol limit. Sleep deprivation leads to slower reaction times, reduced lane control, and microsleeps. Coffee,…
Sleep deprivation kills flies and mice by causing oxidative damage in the gut, a process that antioxidants can reverse, according to a Harvard study.
Sleep deprivation significantly impairs cognitive and physical functioning, likening its effects to alcohol intoxication. Staying awake for 17 hours equates to a blood alcohol concentration (BAC) of 0.05%, while 24 hours is comparable to a BAC of 0.10%, surpassing the…
A systematic review of 21 studies on sleep deprivation shows that going without sleep for extended periods causes visual, auditory, and somatosensory hallucinations, progressing toward psychosis. Perceptual distortions appear after 24–48 hours of sleep loss, followed by more complex hallucinations…
New research confirms sleep deprivation triggers anger by disrupting the brain's ability to regulate emotions via the amygdala and prefrontal cortex.
