ABSTRACT
The comfortability and safety on resort were investigated in terms of resort environments focusing on atmosphere temperature.<br>With regard to the comfortability, first, a discomfort index (DI) defined with atmosphere temperature and relative humidity was demonstrated to be associated with indicators of autonomic nerve activities derived from heart beat variability at the level around DI-70 which was classified into the category of “comfortable for most of people”.<br>Secondarily, it was suggested that the index could be available to evaluate comfortability for given time courses at different resort points with an example of its hourly average in 24 hours a day for a representative month in each season. With regard to the safety, first, stroke incident rate of each month was associated with monthly average atmosphere temperature when the relationship was analyzed using around ten thousands patients data for 7 years from the community-based stroke registration for in Toyama prefecture. On top of that, it has been demonstrated that the atmosphere temperature on one and two days prior to the stroke development was independently effective on the risk of cerebral hemorrhage and subarachnoidal hemorrhage development with the adjustment for patient's sex and age, calendar year, season, relative humidity and atmosphere pressure. Secondarily, morning raise in blood pressure was affected by the room temperature (10°C and 25°C). The lower temperature the more raise in blood pressure.
