Sleep-tracking devices became more common in 2025 as many people looked for ways to improve daily energy and focus. Smartwatches and rings are widely used to record movement and heart rate during rest, allowing devices to estimate sleep quality. Market researchers reported steady growth as users showed strong confidence in wearable technology. However, doctors emphasized that the results should be viewed as general guidance rather than exact medical facts.
Experts explained that most devices are effective at identifying when someone is asleep but less precise when describing sleep stages. Because of this limitation, specialists advised users to observe long-term patterns instead of judging one night’s results. Some users reported feeling anxious after checking sleep scores every morning, especially when results did not meet personal goals. Doctors said this reaction can reduce the benefit of tracking and distract people from healthy routines. Instead, professionals recommended focusing on habits such as regular bedtimes and reduced screen use. Researchers added that future devices may help detect health changes earlier, making sleep tracking more valuable if used responsibly.
