有一种焦虑叫“手表说我没睡好”。随着智能穿戴设备的普及，越来越多人开始依赖智能手表或手环监测自己的睡眠质量。这些设备通过心率、体动等数据判断你是否进入深睡、浅睡或快速眼动阶段，并给出“睡眠评分”。然而，当看到连续几天“睡眠不足”“深度睡眠过少”的提示时，一些人反而陷入新的焦虑——明明感觉睡得不错，却被数据否定。这种由健康科技引发的心理压力，被称为“数据焦虑”或“量化自我焦虑”。更严重的是，有人会因过度关注数据而辗转反侧，反而真的影响了睡眠。专家建议，智能设备的数据可作为参考，但不应成为评判健康的唯一标准。真正的睡眠质量，应结合自身白天的精神状态、情绪和专注力来综合判断。放下对数字的执念，或许才能睡得更安心。
There’s a kind of anxiety called “My smartwatch says I didn’t sleep well.” With the rise of wearable technology, more and more people rely on smartwatches or fitness trackers to monitor their sleep quality. These devices use metrics like heart rate and body movement to estimate whether you’re in deep sleep, light sleep, or REM stages, then assign a “sleep score.” However, when users repeatedly see alerts like “insufficient sleep” or “low deep sleep,” they may develop new anxieties—even if they subjectively feel well-rested. This tech-induced stress is often referred to as “data anxiety” or “quantified self-anxiety.” In some cases, people become so fixated on the numbers that they lie awake worrying about their sleep metrics, ironically worsening their actual sleep. Experts advise treating wearable data as a helpful reference—not an absolute verdict on health. True sleep quality should be assessed holistically, based on daytime alertness, mood, and cognitive function. Letting go of obsession over numbers might be the key to truly restful sleep.
