scientists, but one thing’s for sure: it is something essential in our
lives. It has a crucial role in immune function, metabolism, memory, learning,
and other vital functions, sleep has
many great benefits in the body, especially in the brain. This is just one of
the many benefits of sleep in the brain: it organizes the flow of fluids that
can wash away build-ups of proteins as well as wastes around neurons, from the
study,
When you
sink into a deep sleep, a cycle of activity starts behind your closed eyelids.
First, a slow electrical wave pulses through the brain. A few seconds later,
the amount of blood within the brain drops. Then a wave of cerebrospinal fluid
reverses its usual direction of flow and moves upward through large cavities in
the lower and central portions of the brain. The pattern repeats about three
times a minute for the duration of non-REM sleep, the typically dreamless
phases when your eyes remain still.
In a
recent study, researchers observed the rhythmic sequence uniting these three
phenomena in humans for the first time and found the causal links between them.
Their finding clarifies how sleep may protect the brain’s well-being by driving
elements of an obscure “plumbing system” found in the brain only a few years
ago.
In the near future, this newly discovered mechanism might be
the basis for new treatments to prevent cognitive decline in patients with
Alzheimer’s disease as well as other conditions, more about this study over at Quanta Magazine, well I do not know much about it, but for myself there is nothing better than a good nights sleep to start the day.
