What is the Go2Sleep ring and how does it work?

The Go2Sleep ring is a wearable sleep tracker designed to monitor various physiological parameters during sleep to aid in the assessment of sleep quality and detect potential sleep disturbances. It is worn on the finger, allowing it to track metrics such as heart rate, blood oxygen levels, and movement with its built-in sensors. The device functions by utilizing technology similar to that of pulse oximeters; it emits light that penetrates the skin, allowing it to measure the changes in blood vessels' size with each heartbeat, thereby calculating the different data points. This information is then synced to a smartphone app where algorithms analyze the data to provide insights on sleep patterns, generate reports, and offer suggestions for improving sleep. Additionally, it can also provide vibration feedback for certain events like apnea episodes or significantly low blood oxygen levels, in order to alert the user.
