For maintaining and improving health, it’s essential to have sufficient sleep both in quality and quantity. However, many Japanese have problems of sleep including severe sleep deprivation. Short sleep and sleep disorders increase the risk of lifestyle diseases such as obesity, high blood pressure, diabetes, cardiovascular disease and the risk of death.

To contribute to disease prevention and health promotion, we conduct a wide variety of sleep research in human environmental physiology in collaboration with Dr. Tokuyama and Dr. Abe. For example, we measure energy metabolism and evaluate biological rhythm to examine how bedroom’s environment or lifestyle affects sleep. Through various approaches such as EEG measurements during sleep in laboratory, assessment of sleep at home and human genetic studies to identify genes which regulate sleep, we aim to show lifestyle and sleeping environments to improve sleep quality, and to propose sleep style suitable for each individual based on genetic factors.
