Did you get a good night’s sleep? Did the extra hour in bed make you wake up feeling refreshed? If you answered “yes” to either of these questions, you have your amazing brain to thank.
Researchers at Boston University have gained a greater understanding as to what happens in the brain during sleep. As the brain’s activity slows down and your neurons stop firing, you gradually settle into sleep. It’s during this serene period that your brain starts its housekeeping. While you sleep, blood rapidly drains out of the brain, resulting in a loss of pressure, with cerebrospinal fluid (CSF) rushing in to restore balance.
