EFFECT OF UNIFORM THERMAL ENVIRONMENT WITH CENTRAL AIR CONDITIONING ON RESIDENT SLEEP INDEX

Abstract

The thermal environment of a house is a factor that affects sleep quality. Thus, for maintaining good health, it is important for houses to have an appropriate thermal environment. The influence of ventilation and air conditioning on a house’s thermal environment cannot be ignored. Here, we investigated differences in ventilation and air conditioning equipment by comparing and evaluating the sleep quality of residents using individual air conditioners or central air conditioning. The results suggested that the central air conditioning group had reduced sleep latency, which might increase sleep efficiency in summer.
