Study: To Reduce Dementia Risk, Get 'Goldilocks' Amount Of Sleep

A new study reports that when it comes to sleep, it's actually possible to get too much of a good thing.

According to UPI, research shows getting too much or too little sleep may increase the risk for cognitive decline, or dementia, in older adults.

Chinese researchers analyzed the sleep habits of more than 20,000 English and Chinese adults age 48 to 75.

They found that people who slept for fewer than four hours or more than 10 hours per day showed evidence of declines in cognitive function.
