While heart rate monitoring remains accurate, calorie counts can miss the mark by up to 93%. Experts warn that this reliance on inaccurate data, combined with a fixation on sleep scores and optimization tools, may worsen insomnia. Users are increasingly treating sleep as a performance metric, which professionals suggest transforms a natural process into a source of stress and sleeplessness.Why it mattersThe rise of sleepmaxxing has led users to emp https://www.live-feeds.com/feed/scientists-discover-a-serious-problem-with-sleep-trackershttps://www.live-feeds.com/feed/scientists-discover-a-serious-problem-with-sleep-trackers#u61114Tue, 08 Sep 2026 06:52:11 +0000Researchers have identified a serious problem with sleep trackers that may negatively impact user sleep quality.
