New research shows that getting deep sleep can help prevent Alzheimer’s disease.
Alzheimer’s disease is caused by amyloids and tau tissue that build up on brain tissue where they should not be. This research shows that deep sleep prevents this from happening.
Keyword here “deep” sleep. Not cat naps. The body temperature should drop and the brain should produce slow, rhythmic electrical waves for this cleansing sleep to happen. Scientists liken it to a dishwasher that runs at night, cleaning out the day’s damage if there is any in order to keep the brain clean and healthy.
