Sleep tracking is the process of monitoring your sleep patterns to understand how well you rest each night. Many people use devices like smartwatches or fitness trackers that can measure how long they sleep, how many times they wake up, and even the different stages of sleep, such as REM and deep sleep. This information can help you identify habits that improve or disrupt your sleep quality. By analyzing your sleep data, you can make informed changes to your bedtime routine or environment. For example, if you notice that you sleep better when your room is dark and cool, you can adjust your surroundings to promote better rest. Ultimately, sleep tracking can lead to healthier sleep habits and improved overall well-being.
