A questionnaire investigation on people’s sleep and health in constant temperature and humidity environment in China

In recent years, constant temperature and humidity air-conditioning systems have been widely used and promoted in residential buildings all over the world. At the same time, the influences of long-term stable indoor environment on people’s lives, especially on sleep quality and health, have attracted wide attention. Therefore, in this paper, a questionnaire investigation on people’s sleep and health in constant temperature and humidity environment was carried out in China. By comparing the questionnaire investigation results from the users of constant temperature and humidity air-conditionings with unused, it could be found that people living in constant temperature and humidity houses have better performance in sleep quality, but worse health condition. These results suggested that constant temperature and humidity air-conditioning had an effect on human bodies. The findings can also inform future study on the role of thermal environment on sleep and health.
