Extended Wakefulness
🧠Psych - 161/200
Hey Reader,
Another day, another interesting study researched for you. Totally fresh!
Let’s talk about Extended Wakefulness.
What is it?
Modern society enables a shortening of sleep times, yet long-term consequences of extended wakefulness on the brain are largely unknown. Essential for optimal alertness, locus ceruleus neurons (LCns) are metabolically active neurons that fire at increased rates across sustained wakefulness.
We hypothesized that wakefulness is a metabolic stressor to LCns and that, with extended wakefulness, adaptive mitochondrial metabolic responses fail and injury ensues.
Why do I need to know?
Artificial lighting, longer work commuting times, night-shift work, and increasing availability of computers and televisions have all contributed to shortened sleep times (Centers for Disease Control and Prevention, 2012).
Sleep loss, however, impacts negatively on cognitive performance, including mood, attention, memory, and executive function (McCoy and Strecker, 2011).
SLEEP IS IMPORTANT. DON’T SKIP IT.
