With aging, human body changes. The elderly normally have problem in thermoregulation and sleep quality. Thus, a cold bedroom environment may cause the sleep problems of the elderly. This study focused on the effects of covering heating and mattress heating on sleep quality of the elderly. Experiment was carried out in the subjects’ own bedrooms in winter. Twelve elderly people were exposed to three conditions, following their daily sleeping schedule. Their sleep quality was evaluated subjectively using questionnaires and objectively with a continuously monitored wristband, called Fitbit Charge 2. Compared with no heating, the subjects felt warmer and had higher SE, longer TST, shorter SOL under two heating conditions. The subjects had shorter WASO and higher SE under covering heating, compared with mattress heating. These results suggest that bed heating improves sleep quality of the elderly in a cold environment, which is affordable and convenient for the elderly in cold winter, especially the covering heating.
