What effect can sleep deprivation have on an individual?

• A. Immediate and sustained improvement in cognitive functions
• B. Heightened awareness and alertness
• C. Occurrence of microsleep episodes
• D. Increased motivation to sleep

Answer: (C)

Sleep deprivation can significantly impact an individual's cognitive and physiological functions. One of the most notable effects is the occurrence of microsleep episodes. These episodes are brief periods of sleep that occur when a person is awake and can last for a few seconds to several minutes. During microsleep, the brain momentarily shuts down, leading to lapses in attention and awareness. When an individual is sleep deprived, their ability to maintain focus and alertness diminishes, which can trigger these involuntary microsleep events. These episodes can happen without the person's conscious awareness, posing various risks, particularly in situations requiring sustained attention, like driving or operating machinery. In contrast, immediate and sustained improvement in cognitive functions, heightened awareness and alertness, and increased motivation to sleep do not accurately reflect the effects of sleep deprivation. Instead, they suggest a state of well-restedness and optimal functionality, which is the opposite of what occurs due to lack of sleep. Continuous sleep deprivation leads to cognitive decline, reduced alertness, and an overwhelming desire to sleep, making microsleep a critical concern in the context of inadequate rest.
