Carmel, CA Alzheimer’s Risk Doubles For Those Sleeping Nine Hours Or More Per Nightby Richard Kuehn on 03/16/17
I always thought that sleeping in was good for you but researchers say no! A new study found that older adults who sleep more than nine hours a night after not doing so when they were younger more than doubled their risk of developing dementia a decade later. The increased risk was not seen in those who had always slept that much each night. The researchers suggest that as Alzheimer’s-related changes occur in the brain, people may inadvertently sleep longer as their bodies attempt to remove abnormalities, although additional research on the subject is needed. However, some think that excess sleep could be an early warning sign of dementia coming on.
