New Study Finds That Sleeping Too Much May Cause Your Brain To Decline


We've always heard to get enough rest, you'll need to sleep around 7-8 hours a day. However, did you know that there is such thing as having too much sleep? Getting too much sleep may be bad for your mental faculties and cause conditions like Alzheimer's disease and other cognitive problems in the future.


According to a new study which was conducted by researchers from the Washington University School of Medicine, sleeping too much can result in the same cognitive decline as someone who is getting too little sleep - Balance is definitely key!


The research team studied 100 elderly adults around their mid to late 70s over a length of between 4 to 5 years. Numerous cognitive and neuropsychological tests were conducted to identify signs of cognitive decline during the studies. Individual participant scores on the tests were then added into a single score called the Preclinical Alzheimer Cognitive Composite (PACC) score, in which a higher score signified better cognitive function in the long run.


The researchers also monitored the amounts of sleep participants got using a single-electrode encephalography (EEG) device planted on the participants' foreheads. After combining all factors like age, genetics, and the presence of proteins linked to the development of dementia, they concluded that sleeping for less than 4 and a half hours, and more than 6 and a half hours a night had links with mental and cognitive decline over time.


That said, people are encouraged to keep tabs on their sleep patterns to ensure enough quality rest at night. At the end of the day, sleep is based on your needs and preference!
