Over the decades, research has shown the important role sleep plays in our overall health
A recent study published in the journal BMC Medicine has revealed that individuals with high levels of beta-amyloid in their brain may benefit from deep sleep in terms of protecting against memory loss. Researchers from the University of California, Berkeley have discovered that beta-amyloid, a primary protein linked to Alzheimer’s disease, could be a key driving factor.
There are four main stages of sleep. The third stage of non-rapid eye movement (NREM) sleep is known as deep sleep or slow-wave sleep. Deep sleep is the most restful stage, with slower heart and breathing rates and longer brain waves, making it difficult to wake up from.
According to the researcher, deep sleep played a crucial role in memory retention. Furthermore, the study found that individuals with high levels of beta-amyloid in their brains experienced a significant cognitive reserve boost and improved memory function with an increase in deep sleep duration.
