Lack of Sleep Linked to Increased Risk of Dementia

A new study released in the scientific journal Nature Communications has stated that people age 50 or 60 who regularly slept six hours or less each night were more likely than those who slept seven hours to be diagnosed with dementia.

The study, which was recently reported in both the Wall Street Journal and the New York Times, shared the results of a 30-year longitudinal study comprising of 8,000 participants. 

Study Findings

This study is one of the most persuasive findings yet to suggest that people who are in their 50s and 60s who don’t get enough sleep may be more likely to develop dementia when they are older.


While controlling for factors such as mental health, cardiac, metabolic, issues, the study researchers found that 50-year-olds who were sleeping 6 hours or less a night had a 22% higher risk of developing dementia later in life. Sixty-year-olds were 37% more likely to develop the disorder. 


The field of sleep science presents many challenges. For example, the long-term effects of sleep quality are inherently difficult to study and understand, as they require years of data collection and observation to fully understand.  What sets this study apart from others is that it looks at study subjects over a long period, over 25 years.  Most studies published about sleep and dementia span 20 years or less.

While the field of sleep science and research is still very young, in many ways and there are lots to learn. As we learn more and more about sleep there is a consistent theme, sleep is being proven to be more and more important to both short-term and long-term health.

Start Prioritizing Restorative Sleep Now

“Short sleep is something that we have control over, something that you can change,” says Pamela Lutsey, an associate professor of epidemiology and community health at the University of Minnesota, who was not involved in the research.

Dr. Kristine Yaffe of UCSF adds to this literature as she points out that it is important to not only get more sleep but specifically more restorative sleep, including deep and REM sleep

How Remrise Can Help Increase Restorative Sleep

Remrise has worked with scientists from Harvard and Stanford to develop an all-natural sleep aid that actually promotes restorative sleep. 

We rigorously tested and developed the best formulation with thousands of participants and identified the following benefits of Remrise:

  • Improved restorative sleep by 180%
  • 46% reduction in sleep onset latency
  • 40% reduction in minutes awake throughout the night

Unlike other sleep medications, Remrise doesn’t knock you out and prevent restorative sleep (REM & deep). Our ingredients promote and increase REM & deep sleep, and are safe to use every night. 

As our competitors are not solving the root cause of sleep deprivation (Read: Remrise vs The Rest), Remrise is non-habit forming, drug + hormone-free, and best of all, doesn’t leave you with a groggy wake-up call in the morning.

What our customers have to say

Our customers have reported an average increase in time slept of almost 2 hours, with over double the amount of time spent in deep sleep.

“I sleep so deep with the sleep powder. I feel like it's a great night of sleep and my Oura ring (sleep tracker) shows I get at least 2 hours of deep sleep when I drink it before bed.” - Renee B. 

“I was having trouble sleeping through the night. After I started drinking Remrise before bed, I started allowing deeper and got more restful sleep and my dreams returned. I can’t live without it now!” Kara K.
