Sleep monitoring involves tracking various aspects of sleep, such as duration, quality, and patterns. This can be done using devices like fitness trackers, smartwatches, or dedicated sleep monitors. These tools often measure heart rate, movement, and even breathing to provide insights into how well a person sleeps. The data collected from sleep monitoring can help individuals identify sleep issues, such as insomnia or sleep apnea. By analyzing this information, people can make informed changes to their sleep environment or habits, ultimately improving their overall health and well-being.
