Research theme





Outline of the research

Japan is one of the countries with the longest life expectancy, and while life expectancy continues to grow, the incidence of dementia continues to rise. It is said that there are about 10 years between healthy life expectancy and average life expectancy, and the challenge is how to shorten these years. When we look ahead to these 10 years, I would like to examine what we should do preventively in our daily lives, from the stage before cognitive and physical functions decline. My study’s goal is to clarify what and how much we should do to extend our healthy life span. I also aim to conduct research so that what we examine through research can be delivered to those who need it as soon as possible.

Thoughts on research

My ultimate goal in my research is to make it possible to easily and objectively measure both mental and physical health based on quality of life and happiness. Health is known to be influenced by psychological well-being and physical health. By clarifying the health status based on quality of life and happiness, I believe that deviating from this status will lead to prediction of the risk of some diseases and improvement of lifestyle to prevent diseases before they occur. I would like to think about health to reduce future diseases and problems.
