Sleep tracking is a field of research focused on monitoring and analyzing a person's sleep patterns and quality using various technologies and devices. This can include wearable sensors, smartphone apps, or bedding with integrated sensors to track factors such as sleep duration, sleep stages, heart rate, and movement during the night. The data collected from these devices can provide insights into a person's sleep behavior, identifying trends and potential issues such as sleep disorders or poor sleep hygiene. Sleep tracking research aims to improve understanding of sleep health and promote better sleep habits for overall well-being.
