The benefits of good sound sleep are well-known and include improved metabolism, immunity, heart-function, and better concentration. A recent study published in the Journal of Neurotrauma has revealed that sound sleep helps the brain to heal faster from traumatic injury . In this study, the researchers used a new technique to measure the effect of sleep on healing traumatic brain injury.
They used magnetic resonance imaging (MRI) to examine the degree of enlargement of perivascular spaces in the brain , an important part of the brain’s waste clearance system known as the glymphatic system . The glymphatic system collects the metabolic proteins accumulated in the brain and clears them off during sleep. During trauma or brain injury, brain blood vessels are saturated with metabolic proteins, and a night of sound sleep could help clear the waste, thereby improving the recovery from the…
