As we’ve all heard since grade school, it’s important to get at least a full eight hours of sleep every night. Dr. Max Cynader of the Vancouver Coastal Health Brain Research Centre at UBC explains, sleep is critical to our brain’s health, functionality and to our memory.
According to Cynader, if we don’t get enough sleep “individual groups of brain cells actually go to sleep intermittently during the day.” But Cynader says that the importance of sleep stretches far beyond simply keeping our brains active and energized. It is also critical to memory formation and problem solving.
