Ten years ago, a watch only told you the time. Today, a watch can tell you how fast your heart is beating, how many steps you took, how deeply you sleept, and even how stressed you are. These devices, called wearables, have moved from the wrists of sports fans to the wrists of ordinary people. And they are changing how we think about health.

The appeal is easy to understand. A wearable turns abstract ideas — "exercise more," "sleep better" — into numbers you can see. If your watch tells you that you only slept five hours last night, you are more likely to go to bed earlier tonight. If it shows that your heart rate stays high during rest, you may decide to see a doctor before a small problem becomes a big one. In this sense, wearables are not just gadgets. They are tools that help people take responsibility for their own bodies.

But there is another side. A watch that measures everything can also create anxiety. Some people check their heart rate dozens of times a day. Others cannot sleep because they are worried about their sleep score. The device that was supposed to improve health becomes a source of stress. And the numbers are not always accurate. A wearable may count a car ride as steps, or misread a heartbeat during exercise. Treating the device as a doctor, rather than as a rough guide, can lead to unnecessary worry.

The best way to use a wearable is the same as the best way to use any tool: with common sense. Let the numbers guide you, but do not let them rule you. Notice when your body feels tired, even if the watch says you are fine. Go for a walk because it feels good, not only because the step count is low. Technology can tell you a great deal about your body. But it cannot tell you how to live. That part is still yours.

十年前，手表只告诉你时间。今天，手表能告诉你心跳多快、走了多少步、睡得有多深，甚至你有多紧张。这些设备叫做可穿戴设备，已经从运动爱好者的手腕走到了普通人的手腕。它们正在改变我们对健康的看法。吸引力很容易理解。可穿戴设备把抽象的概念——"多锻炼""睡更好"——变成你能看到的数字。如果手表告诉你昨晚只睡了五个小时，你今晚更可能早点上床。如果它显示你休息时心率仍然很高，你可能会在小问题变成大问题之前去看医生。从这个意义上说，可穿戴设备不只是小器具。它们是帮助人们为自己的身体负责的工具。但还有另一面。一块测量一切的手表也可能制造焦虑。有些人一天查几十次心率。另一些人因为担心睡眠分数而睡不着。本应改善健康的设备变成了压力的来源。而且数字并不总是准确的。可穿戴设备可能把坐车计成步数，或者在运动时误读心跳。把设备当成医生而不是粗略的指南，可能导致不必要的担忧。使用可穿戴设备的最好方式和使用任何工具一样：用常识。让数字引导你，但不要让它们支配你。注意你的身体什么时候感到疲倦，即使手表说你很好。去散步是因为感觉好，而不只是因为步数低。科技能告诉你很多关于你身体的事。但它不能告诉你如何生活。那部分仍然是你的。
