Sleep tracker comparison reveals Garmin as most reliable among three devices

A month-long comparison of three sleep trackers—Oura Ring, Garmin Forerunner 165, and Eight Sleep Pod Cover—revealed significant differences in sleep data. While Garmin and Oura provided similar results, Eight Sleep often reported higher sleep hours, which the author found questionable. The author noted that Eight Sleep may have inaccurately detected sleep due to factors like scrolling on a phone in bed. Garmin's readings were deemed the most reliable, while Oura was favored for its comfort and ease of use. The author plans to test additional sleep trackers in the future to gather more data and improve accuracy in sleep tracking.
