Our Research

Emerging research is confirming the importance of sleep, and how destructive a lack in duration or quality of sleep can be to the health and wellbeing of individuals and even society at large. Kakuichi Institute is making efforts to help improve sleep through our work with earthing technology, and we are in the process of testing new technologies that may further assist in the improvement of sleep and wellbeing.

Why 'Sleep'?

"If we all slept enough? ...Our healthcare burden would plummet, we would have better mental health and fewer suicides... our business would be more productive, global economies would be healthier, our roads would be safer and our children would be smarter... sleep is the very best insurance policy you could ever wish for."

- Dr. Matthew Walker, Professor of Neuroscience at the University of California, Berkeley

People often overlook the importance of sleep, and large proportions of the population do not get sufficient sleep to live healthy lives.

In the United States alone, roughly 10% of the population is affected by a sleep disorder 1, and 1 in 3 adults get less than the minimum 7 hours sleep per night 2. Sleeping less than 7 hours per day is associated with an increased risk of developing chronic conditions such as obesity, diabetes, high blood pressure, heart disease, stroke, and mental illness 3, all of which are problems that commonly present themselves in our unhealthy society.

In order to remediate the problems caused by poor sleep, we must first understand them. Please see this video by sleep scientist Dr. Matthew Walker, professor of neuroscience and psychology at the University of California, Berkeley. Dr. Walker explains in detail the importance of sleep, and the consequences of insufficient sleep. Dr. Walker also stresses the correlation between poor mental health and lack of sleep, showing that every single mental illness coincides with a lack of sleep.

Studies

  • REM sleep selectively prunes and maintains new synapses in development and learning, Peking University (Sep 2016)

    REM sleep has multifaceted functions in brain development, learning and memory consolidation by selectively eliminating and maintaining newly formed synapses.

  • Sleep Drives Metabolite Clearance from the Adult Brain, University of Rochester (Sep 2016)

    Metabolic waste products of neural activity were cleared out of the sleeping brain at a faster rate than during the awake state... The restorative function of sleep may be a consequence of the enhanced removal of potentially neurotoxic waste products that accumulate in the awake central nervous system.

  • Manipulating circadian clock neuron firing rate resets molecular circadian rhythms and behavior, Vanderbilt University (Nov 2014)

    People who had most of their daily exposure to even moderately bright light in the morning had a significantly lower body mass index (BMI) than those who had most of their light exposure later in the day.

  • Timing and Intensity of Light Correlate with Body Weight in Adults, Northwestern University (Apr 2014)

    People who had most of their daily exposure to even moderately bright light in the morning had a significantly lower body mass index (BMI) than those who had most of their light exposure later in the day.

  • Happy as a Lark: Morning-Type Younger and Older Adults Are Higher in Positive Affect, University of Toronto (Jun 2012)

    Our results demonstrate that morningness is associated with higher positive affect among both younger and older adults. Morningness was also associated with better subjective health.

  • Human relational memory requires time and sleep, Columbia University (May 2007)

    Relational memory, the flexible ability to generalize across existing stores of information, is a fundamental property of human cognition. Little is known, however, about how and when this inferential knowledge emerges.

    These findings demonstrate that human relational memory develops during offline time delays. Furthermore, sleep appears to preferentially facilitate this process by enhancing hierarchical memory binding, thereby allowing superior performance for the more distant inferential judgments, a benefit that may operate below the level of conscious awareness.

Our Experiments

At Kakuichi Institute, we set out to improve the health of the individual and society. We believe there is no better way to do this than to improve the duration and quality of the time we spend sleeping, which makes up roughly 1/3rd of the time we spend alive. In order to do that, we are experimenting with new tools that may improve sleep. Early results from our experiments are extremely promising.

Cymatics and Sleep

Kakuichi Institute is currently experimenting with cymatic therapy in application to humans, through a new unique bed design incorporating speakers playing light cymnatic frequencies during sleep. Our study into the outcomes of this therapy is ongoing, and we plan to publish our research into Cymatics and Sleep in the near future.

Earthing and Sleep

Extensive research data shows that people may live healthier lives if they are regularly connected to the Earth, with reduced pain and inflammation, and improvements to mood, circulation, and most importantly, to sleep duration and quality. To that end, we have created sleep aids, and they are available from our sister site, earthing.jp.
