What are the behavioral signs of sleep deprivation?

The behavioral signs of sleep deprivation are well-documented and include a range of negative effects on an individual's cognitive and emotional functioning. Impairments in cognitive function manifest as difficulties in concentration, decision-making, and problem-solving. Sleep-deprived individuals often experience irritability, leading to mood swings and an inability to cope with stress, which can further impact their social interactions and overall mental health. Additionally, the increased likelihood of accidents, whether due to reduced alertness or slow reaction times, is a significant risk associated with lack of sleep. These combined factors illustrate how sleep deprivation can severely hinder an individual's daily functioning and safety, confirming that option C accurately represents the consequences of insufficient sleep.
