Environmental health nursing is the field in which we consider nursing through the relationship between living environment and human. As F. Nightingale described in “Notes on Nursing” that environment is important factor for health, the environment is one of basic concepts in nursing. Given nursing can be defined as activity that arranges current living environment in order, the living environment is wide concept including not only physical but also psychological environment, In Environmental Health Nursing lab, we perform many studies, in wide fields, which contribute to promotions of health and safety.

Research and Education

The main research themes of our staff are as follows.
1. Shift-worker’s health
2. Relationship between living environment and human sleep-wake cycles
3. CPAP treatment adherence of OSAS patients
Appropriate methodology to each objective of our themes can be selected from laboratory experiments, epidemiological study using cohort method, to case studies as evidence of hypothesis. Electroencephalogram, body temperature, heart rate activity can be measured in our laboratory. Our intervention and support activity can be possible for promoting community-based people’s health.
Research results and experiences over the studies are feed-back to part of education contents in the two classes entitled “Principles of Nursing” and “Basic Techniques for Nursing” which were prepared for the first and second grades of the bachelor course.
Actual experiences of nursing before graduate school are very valuable for making graduate students’ research purpose. The research studies of many themes are currently going on. Previous researches were commended from several academic meetings and Kyoto University (President Award). These academic activities make our students encouraged.
