Model-predicted outcomes based on environmental variables. In creating these graphs, we used the median value of all other variables (a female with MOCA score of 25, SPPB score of 10, comorbidity score of 5, who lives in private housing, in a weekday with a day length of 12.3 hours, and bedroom nighttime humidity of 44.2%). In rows two and three, nighttime ambient temperature was set to 22 °C. TST is total sleep time, SE is sleep efficiency, and RSTLS is sleep restlessness.
