Withings BodyScan 2 Review: Worth Its Weight
Withings BodyScan 2 Review: Worth Its Weight
Withings BodyScan 2 评测：物有所值吗？
WIRED Rating: 9/10 WIRED 评分：9/10
THE GOOD: Dozens of health metrics measured, with weekly deep-dives (or more on demand). Very user-friendly hardware makes it easy to get a good scan. Professional ECG reading is arguably worth the price of entry. 优点： 可测量数十项健康指标，并提供每周深度分析（或按需进行更多分析）。极其用户友好的硬件设计，让获取高质量扫描数据变得简单。专业的 ECG（心电图）读数功能可以说值回了票价。
THE BAD: Extremely expensive, and it all but requires a subscription. Withings intelligence can be confusing (and contradictory). 缺点： 价格极其昂贵，且几乎强制要求订阅服务。Withings 的智能分析有时会令人困惑（甚至自相矛盾）。
I’m going to be honest from the start: No, you probably don’t need a $600 scale in your bathroom if you are just doing occasional weigh-ins. Hell, I don’t even know that elite athletes need to make this kind of extreme outlay even if they need to periodically check on how their training is going. 我先坦诚地说：如果你只是偶尔称个体重，那么你的浴室里大概并不需要一台 600 美元的体重秤。说实话，即便对于需要定期检查训练进展的精英运动员来说，我也不确定他们是否有必要进行这种极端的投入。
But I’m going to make the case for the Withings BodyScan 2 anyway. After spending several months with the device, the scale and its ecosystem have forced me to dig deeper into my health than ever before. At this point, I’m not sure I could go back to an older-model scale—even a very smart one like the original Withings Body Smart, which I used for years. 但无论如何，我还是要为 Withings BodyScan 2 说几句好话。在使用这款设备几个月后，它及其生态系统迫使我比以往任何时候都更深入地了解自己的健康状况。到了现在，我不确定自己是否还能用回旧型号的体重秤——即使是我用了多年的、同样非常智能的初代 Withings Body Smart。
Getting a Handle on Health
掌控健康
There’s not much to distinguish the BodyScan 2 hardware from other smart scales aside from its handlebars, an indication that this device belongs to the now-burgeoning full-body scanner or body composition scale category. The device is, however, sleeker than most of its competition, featuring a svelte handle that somehow finds room for a small color LCD screen without the need for any extra bulk. All of your body metrics are showcased on this screen in real time, as they’re being measured, alongside any quick tips from Withings about how to get the best reading each time you hop on. 除了手柄之外，BodyScan 2 的硬件与其他智能秤并没有太大区别，这表明该设备属于目前正在兴起的全身扫描仪或身体成分分析秤类别。不过，这款设备比大多数竞争对手更精致，其纤细的手柄巧妙地容纳了一块小型彩色 LCD 屏幕，而无需增加额外的体积。当你站上去测量时，所有的身体指标都会实时显示在这块屏幕上，同时还会显示来自 Withings 的快速提示，教你如何每次都能获得最佳读数。
The unit offers two types of weigh-ins. Daily scans take about 30 seconds and include weight, an estimate of muscle and fat percentage (whole body and segmented across torso, arms, legs, and viscera), an estimate of basal metabolic rate, vascular age, and pulse wave velocity—though only a portion of these measurements are displayed live on the display. 该设备提供两种称重方式。日常扫描大约需要 30 秒，包括体重、肌肉和脂肪百分比估算（全身以及躯干、手臂、腿部和内脏的分段数据）、基础代谢率估算、血管年龄和脉搏波速度——尽管其中只有一部分测量结果会实时显示在屏幕上。
All of that is fairly par for the category, and it’s not until the big guns come out that the BodyScan 2 really starts to show off its biggest tricks. By default, you’re prompted to take a more intensive 90-second “longevity scan” every seven days, and I’ve come to simultaneously welcome and dread the weekly encounter. Here you’re subjected to a battery of tests, including all of the above plus measurements of blood oxygen level (SpO2), nervous system responsiveness, and—most notably—a full six-lead electrocardiogram that includes the ability to detect atrial fibrillation. 这些功能在同类产品中相当标准，直到“重头戏”登场，BodyScan 2 才真正开始展示其绝活。默认情况下，系统会提示你每七天进行一次更深入的 90 秒“长寿扫描”，我对这种每周一次的体验既期待又畏惧。在这里，你要接受一系列测试，包括上述所有指标，外加血氧水平 (SpO2)、神经系统反应性测量，以及最值得注意的——完整的六导联心电图，其中包括检测心房颤动的功能。
While some of these are, of course, more useful than other measurements—I’m still not sure how my nerve response score (76) could possibly be of any real, clinical use—it’s the ECG that makes the BodyScan 2 truly stand out in the field. Watching those heart-driven waveforms crawl across the BodyScan 2’s handlebar LCD is a nerve-wracking thrill. It’s perhaps no wonder that my pulse rate quickens every time I complete one of the tests, nervous about what the system may uncover lurking inside my chest. 虽然其中一些指标显然比其他指标更有用——我至今不确定我的神经反应评分（76 分）能有什么真正的临床用途——但正是 ECG 功能让 BodyScan 2 在该领域脱颖而出。看着那些由心脏驱动的波形在 BodyScan 2 的手柄 LCD 屏幕上缓慢爬行，这是一种令人紧张的刺激感。难怪每次完成测试时我的脉搏都会加快，因为我总是担心系统会发现我胸腔内潜藏着什么问题。
The Subscription Will (Also) Cost You
订阅服务（同样）需要付费
When finished, the BodyScan 2 invariably sends you to the Withings mobile app for the details, which is where things really get interesting. The Withings app is easy to navigate if you just want a quick look at your vitals either in the moment or over time, but new additions driven by the BodyScan 2 really take things into a whole new world. 测量完成后，BodyScan 2 会自动将你引导至 Withings 移动应用程序查看详情，而这正是事情变得真正有趣的地方。如果你只是想快速查看当前或一段时间内的生命体征，Withings 应用程序非常易于操作，但由 BodyScan 2 驱动的新增功能确实将体验带入了一个全新的境界。
You’ll need a subscription (I know, I know) to unlock everything, specifically a new service called Withings+, which costs $10/month or $100/year. It’s a big ask, but to be frank, there’s not much reason to purchase the BodyScan 2 without it. 你需要订阅（我知道，我知道）才能解锁所有功能，具体来说是一项名为 Withings+ 的新服务，费用为每月 10 美元或每年 100 美元。这是一个不小的要求，但坦率地说，如果没有它，购买 BodyScan 2 的意义就不大了。
Withings+ is built around an AI health assistant that is basically the equivalent of what would happen if Claude knew everything about your body and lifestyle. Of course you can ask it questions about various readings or health strategies, but you’ll probably spend more time checking out the various charts and graphs that are generated every time you step on the scale. Your health data is sliced and diced to offer insights about your vascular age and your heart age (not the same thing, it turns out), as well as generating all manner of scores ranking various other aspects of your health. Withings+ 的核心是一个人工智能健康助手，它基本上相当于一个了解你身体和生活方式所有细节的 Claude。当然，你可以向它询问有关各种读数或健康策略的问题，但你可能会花更多时间查看每次称重时生成的各种图表。你的健康数据会被拆解分析，从而提供关于血管年龄和心脏年龄（事实证明这是两码事）的见解，并生成各种评分来评估你健康的其他方面。
This can all get quite obtuse—understanding your Readiness score vs. your BodyPath score vs. your Health score can take a lot of digging, and results can often be in conflict. As well, some of this information requires extra hardware. For example, I have a sleep monitor under my mattress but don’t habitually carry a step tracker or fitness monitor. As such, Withings+ tends to wildly underestimate my steps—nor can it reach any conclusions about my nutrition, since I don’t digitally track what I eat, either. Maybe this is all part of Withings’ subtle way of encouraging me to buy more of its products to track all this stuff. 这一切可能会变得相当晦涩——理解你的“准备度评分”(Readiness score)、“身体路径评分”(BodyPath score) 和“健康评分”(Health score) 之间的区别需要深入研究，而且结果往往会相互冲突。此外，其中一些信息需要额外的硬件支持。例如，我在床垫下放了一个睡眠监测器，但并没有习惯佩戴计步器或健身追踪器。因此，Withings+ 往往会严重低估我的步数——它也无法对我的营养状况得出任何结论，因为我也没有数字化记录饮食的习惯。也许这正是 Withings 鼓励我购买更多产品来追踪这些数据的隐晦方式。
Withings+ isn’t always spot-on—it called out poor sleep from two nights previous rather than last night in answering a simple health question—but it’s surprisingly easy to get lost in its deep analytics, even if I don’t think there’s much I’m really going to be able to do about my heart’s “responsiveness” rating (a measure of how quickly it starts pumping after receiving an electrical signal to beat). At the very least, the information is something I intend to discuss with my doctor at my next appointment; you can even generate a PDF summary of your entire health picture to share with your medical team. Withings+ 并不总是准确的——在回答一个简单的健康问题时，它指出了前天晚上的睡眠质量不佳，而不是昨晚——但它确实很容易让人沉浸在其深度分析中，即使我认为我对于心脏的“反应性”评分（衡量心脏在接收到跳动电信号后开始泵血的速度）其实做不了什么。至少，这些信息是我打算在下次就诊时与医生讨论的内容；你甚至可以生成一份完整的健康状况 PDF 摘要，与你的医疗团队分享。
The objectively most interesting feature of Withings+ however is that it allows you to have your ECG read by a human physician. The feature is buried a bit in the app, and it’s not automatic: You have to manually request an ECG analysis. 然而，Withings+ 客观上最有趣的功能是，它允许你让专业医生解读你的心电图。该功能在应用程序中隐藏得较深，且不是自动触发的：你必须手动请求进行心电图分析。
