内容記述 Japanese people are known for their short sleep time, which is resulting from their late bedtime. Light\
exposure, especially with short wave length, has significant effects of delaying circadian rhythms. Room lightsused in Japanese houses are mostly “bright and white” fluorescent or LED devices. There are many laboratory experiments demonstrating the effects of light on sleep and wake patterns, however, light effects have not been confirmed in actual house settings. We conducted an intervention study of changing light condition in actual houses. We provided “dim and umber” type light devices to the house with “bright and white” type light devices. In experimental group, where the lights were changed to the “dim and umber types, sleep and wake patterns were advanced significantly, compared to the control group. While in the control group with “bright and white” light type, the residents showed significant delay in their sleep and wake patterns, only within a week period. In the experimental group, they showed significant improvements in their mental health. There are possibilities of beneficial changes, if the “dim and umber” type light settings are introduced into Japanese houses.
