From smartwatches to rings to mattress sensors, sleep trackers have become a common part of nightly routines. With a glance at your phone each morning, you can see your “sleep score,” REM percentage, heart rate, and even estimated oxygen levels.
But do these devices actually improve sleep—or can they sometimes make it worse?
Let’s explore the benefits and the limitations.
A good night’s sleep depends on more than just the right mattress and pillow. Temperature plays a major role in how well you rest. If you’ve ever tossed and turned because you were too hot or shivered under too many blankets, you know how disruptive temperature fluctuations can be. That’s where temperature-controlled beds come in. Designed to keep your sleep environment at just the right level of comfort, these innovative beds are becoming increasingly popular among people who want to optimize their sleep quality.
