Your brain is a garbage can! Harmful waste proteins collect between brain cells during waking hours. These toxins are washed away during sleep (Glymphatic System).
REGULATION OF MOOD
Good sleep is required to allow time for the cognitive or “thinking” parts of your brain to connect with the emotional areas of your brain, to keep your mood stable and well balanced (Prefrontal Cortex/Amygdala).
AID IN MEMORY AND LEARNING
Sleep plays a critical role in helping a person focus and learn efficiently. It is also needed to keep a memory stable in the brain and allow you to recall that information in the future (Cerebrum and Hippocampus).
INTERNAL CLOCK RHYTHM
Circadian rhythm is the natural system designed to regulate sleepiness and wakefulness. Light is a strong driver of this system, traveling through the eyes retina’s, sending messages to the brain to stay alert (Suprachiasmatic Nucleus).
NAVIGATE JUDGEMENT
The “reward center” of the brain, where we derive pleasure, can be negatively affected if you do not get enough sleep. You are more likely to take risks, like drowsy driving or using drugs (Striatum/Prefrontal Cortex).
