Using wrist temperature to infer sleep

Sleep is a crucial and substantial biological process. While many wearables monitor sleep, they focus on estimating when people are asleep, but do not take into account circadian rhythms. Circadian rhythms are the biological processes that influence sleepiness and wakefulness. Research has shown that wrist temperature is influenced by our circadian rhythm. We are investigating how sleep and sleepiness are reflected in wrist temperature and how these patterns are influenced by age and dementia. The results of this research are expected to result in a better understanding of sleep that could inform sleep management strategies that support better sleep quality.
