High night-to-night variability in ambient temperature is associated with increased sleep timing irregularity
Our findings highlight that high night-to-night temperature variability is associated with a 20%-50% increase in sleep timing irregularity, with central and southern regions being more affected. Given that sleep irregularity is associated with adverse health outcomes, targeted interventions to mitigate the impact of temperature variability on sleep health is an important public health priority.
