Your Brain is Restored During Sleep, and You Wake Up Refreshed and with A Clear Mind

Your brain
is restored during sleep,
and you wake up refreshed
and with a clear mind.
The first purpose of sleep
is restoration.
Every day,
your brain
accumulates the metabolic waste
as it goes about its normal neural activities.
While this is completely normal,
too much has been linked
to neurological disorders
such as Alzheimer's disease.

Alright, how do we get rid of metabolic waste?
Recent research has suggested
that sleep plays a crucial role
in cleaning out the brain each night.
While these toxins can be flushed out
during waking hours,
the researchers have found
that clearance during sleep
is as much as 2 hours faster.

The way this process happens is remarkable:

During sleep,
brain cells actually
shrink by 60 percent,
allowing the brain's waste-removal system
called the glymphatic system
to essentially "take out the trash"
more easily.
The result?
Your brain is restored during sleep,
and you wake up refreshed
and with a clear mind.
