Wearable Technology in Circadian Rhythm Research: From Monitoring to Clinical Insights

This review article explores the role of wearable technology in circadian rhythm research, providing an in-depth examination of its applications, benefits, limitations, and future potential. Wearable devices continuously monitor physiological parameters such as movement, heart rate, skin temperature, and light exposure, allowing researchers to analyze circadian rhythms in real-world settings. By collecting data on circadian phase shifts, amplitude, and stability, these devices offer valuable insights into the relationship between circadian rhythms and health outcomes. The article discusses the various types of wearable devices and key data collected by these devices. Additionally, it outlines analytical methods used to interpret circadian rhythms. The article also highlights the association between circadian rhythm disruptions and increased risks of cardiovascular disease, diabetes, and neurodegenerative disorders. Finally, the review addresses current challenges in wearable-based circadian research and future direction, including limited validation against gold-standard methods, restricted access to raw data, and algorithm transparency issues.
