Attention, Sleepyheads! Too Much Sleep May Raise Your Risk Of Dementia

by Brandon Topp

Love to sleep in? You might want to watch just how many z-z-z's you're catching each night: A recent study published in Neurology found that averaging more than nine hours of sleep per night makes you more likely to develop dementia. Consider that a wakeup call, avid sleepyheads, and one that adds to the growing list of habits linked to dementia — a disease that 47.5 million people suffer from, according to the World Health Organization

Looking at your mental health from both short-and-long term perspectives is an important part of building lasting relationships, like those we feature on our original series Altar’dEach episode follows a couple who we separate for 90-days of physical training and personal growth before reuniting for their wedding.

Like the show's devoted lovers, consider your long term health by looking at these new findings on the relationship between dementia and sleep:

The Study Tells Us Multiple Things About Dementia. 

The study came from Dr. Sudha Seshadri of Boston University School of Medicine, and it monitored nearly 2,500 participants with an average age of 72. Subjects reported how many hours they slept each night at the beginning of the study; ten years later, they updated the researchers on their sleep numbers. 

The 234 cases of dementia observed in this group after the decade-long follow-up showed that individuals who slept over nine hours every night were twice as likely to get dementia. Additionally, Seshadri said in a statement, “Participants without a high school degree who sleep for more than nine hours each night had six times the risk of developing dementia in 10 years as compared to participants who slept less.” 

The variable of education level, as well as the sleep numbers, tells us a lot about how to prevent dementia. The main take away is that keeping an active mind from a young age is important. Bottom line, if you’re in school, finish it out. If you’re a parent, encourage your kids to pursue an active education. Additionally, simply be conscious of sleeping within the seven-to-nine hour window recommended by the National Sleep Foundation

FYI: Sleeping Too Little Can Also Raise Your Risk Of Developing Dementia. 

This piece from Medical Daily points out that getting too little sleep can also lead to dementia. It reads, “Missing out on deep non-REM (rapid eye movement) sleep may allow proteins linked to dementia to have easier access to the brain.”

This just heightens the importance of trying to stay within that recommended window of seven-to-nine hours, and keep those exceptional evenings to a minimum.
