It could be that the brain needs to fire up for short periods in order to help pump the increased fluid out to prepare for another rinse.
- clort 10y agoWhat I thought of, when I read that was that perhaps the shrinking is related to reduced blood flow or reduced blood absorption (does blood pressure raise or lower during sleep?) and this is also related to sleep itself, in the same way that a chokehold causes unconsciousness by restricting the oxygen reaching the brain
