过度追求完美的睡眠分数可能适得其反。医学专家警告称，这种被称为"睡眠最大化"的行为可能导致"正念睡眠强迫症"，一种实际上会恶化睡眠质量的心理障碍1。睡眠追踪设备自2009年首款商业化产品Fitbit Classic面世以来，已成为许多人监测睡眠的工具1。
然而，专家质疑这些设备的科学基础。医学专家阿兰娜·海尔博士表示："睡眠分数完全是编造的"1，并指出"睡眠科学中没有任何被认可的'睡眠分数'"1。牛津大学的研究进一步揭示了这一现象的危害：即使睡眠分数是随机生成的虚假数据，被告知睡眠不良的参与者在第二天报告了更强的疲劳感和精神警觉性下降1。这表明人们对数据的心理反应本身就足以影响实际睡眠体验。
睡眠追踪设备的准确性也受到质疑。Oura公司上月在旧金山遭起诉，指控其睡眠追踪准确率"等同于抛硬币"1。睡眠专家尼尔·斯坦利建议采取更简单的方法，建议卧室保持"相对凉爽、黑暗和安静"，而非执着于追求完美的睡眠条件1。
Medical specialists are cautioning against the pursuit of perfect sleep scores through wearable tracking devices, arguing that the practice—dubbed "sleepmaxxing"—can trigger a psychological condition that ultimately undermines rest.1 According to Dr. Alanna Hare, the numerical scores generated by these devices are fundamentally unreliable, as "sleep scores are completely made up" and "there is no recognized 'sleep score' in sleep science."1 The concern centers on a condition referred to as "orthosomnia," a form of obsessive focus on sleep metrics that paradoxically degrades sleep quality rather than improving it.1
Research has demonstrated the psychological power of sleep tracking data, regardless of its accuracy.1 An Oxford University study found that participants who were told they had experienced poor sleep—even when presented with randomly generated false data—reported heightened fatigue and diminished mental alertness the following day.1 This phenomenon underscores how the perception of poor sleep can become self-fulfilling.1 Adding to credibility concerns, sleep tracking company Oura faced a lawsuit filed last month in San Francisco, with allegations that its sleep tracking accuracy is "equivalent to flipping a coin."1
Sleep expert Neil Stanley recommends focusing on basic sleep hygiene principles rather than chasing optimal metrics, suggesting that bedrooms should simply be kept "relatively cool, dark, and quiet."1 The first commercially available sleep tracking device, the Fitbit Classic, launched in 2009, initiating what has become an increasingly pervasive trend of quantifying sleep.1
