Sleep Deprivation Weakens Control and Fuels Emotional Instability
A brain imaging study reveals that sleep deprivation leads to a significant reduction in activity in the prefrontal cortex, the area responsible for decision-making, impulse control, and social judgment. After just 24 hours of sleep debt, this critical part of the brain shows diminished function, while the amygdala, linked to emotional responses, exhibits increased activity. This shift in brain dynamics not only alters cognitive abilities but also contributes to behaviors like cyber loafing, highlighting the broader implications of inadequate sleep on productivity and emotional regulation.
