So it’s common knowledge that the elderly, as they age, are plagued by deteriorating memory. But this isn’t just because their bodies are failing. It’s because they’re not able to get adequate amounts of restful sleep!
Scientists at UC Berkeley conducted surveys where they tested subjects of all ages on memory retention and then tested them again after a night of sleep. While most of the subjects performed on par with one another before sleeping, the elderly performed much more poorly afterwards. So seniors aren’t actually worse at remembering; their brains are actually impaired by the inability to process new memories brought on by lack of restful sleep!
So for those of us who are not getting adequate amounts of deep sleep, we’re basically performing at the cognitive level of senior citizens.
