Smartwatches, fitness trackers, and smart rings offering non-invasive blood glucose monitoring are gaining popularity, but the FDA cautions against relying on their readings. These devices, while convenient, often lack the accuracy and reliability of traditional blood glucose meters.
Why the FDA’s concern? Non-invasive glucose monitoring technology is still relatively new and unproven. Current methods often rely on indirect measurements like optical sensors or sweat analysis, which can be affected by numerous factors – hydration levels, skin temperature, and even the type of lotion used. This can lead to significant inaccuracies, potentially resulting in dangerous health decisions for individuals with diabetes.
What are the alternatives? For accurate blood glucose monitoring, the FDA continues to recommend using FDA-cleared blood glucose meters and consulting with a healthcare professional for appropriate testing and management strategies.
The future of non-invasive glucose monitoring? Research and development in this field are ongoing, with promising advancements in sensor technology and data analysis. However, until these technologies undergo rigorous FDA approval and demonstrate consistent accuracy comparable to traditional methods, relying on them for critical health decisions is strongly discouraged.
In short: While smartwatches and similar devices offer many convenient features, using them to monitor blood sugar can be risky. Always consult with your doctor and use FDA-approved methods for managing your diabetes.
What’s the difference between smartwatches and health watches?
Smartwatches and health watches both tell time, but that’s where the similarity ends. Health watches, or fitness trackers, prioritize fitness tracking features above all else. Think step counting, heart rate monitoring, sleep analysis – these are their core functionalities. They’re stripped-down devices focusing solely on health metrics.
Smartwatches, however, offer a much broader feature set. While many include robust fitness tracking capabilities rivaling dedicated health watches – often with GPS and advanced metrics like VO2 max – they also boast features like notifications for calls and messages, app support, music playback, contactless payments, and even voice assistants.

How much can you trust smartwatches?
Smartwatches are handy, but don’t treat them as gospel. A 2025 study involving Apple Watch 2, Fitbit Charge 2, and Alta showed accuracy issues of around 10-15% in step counting. You can generally trust the step count during brisk walks, but less so during household chores or slow ambling. This inaccuracy stems from the limitations of the sensors; they struggle to differentiate between actual steps and other movements.
Accuracy also depends on the watch model and your individual physique. Newer models generally offer improved accuracy, but factors like arm swing and body type still affect readings. Some watches use GPS, boosting accuracy outdoors, but this drains battery life faster and doesn’t work indoors.
Beyond step counting, other metrics like heart rate and sleep tracking also have inherent inaccuracies. These readings are estimates, not precise medical-grade data. While helpful for general fitness tracking and motivation, rely on professional medical advice for health assessments.
Consider this: The variations are part of the equation. Consistent use over time gives you a better overall picture than focusing on daily fluctuations. Don’t obsess over minute discrepancies – the bigger picture of your activity level is what truly matters.
Can smartwatches be trusted for accurate pulse readings?
So, I was looking into those smartwatches that track your heart rate, right? Turns out, according to a study published in JAMA Cardiology, they aren’t as accurate as you might think. American scientists found that fitness trackers, including smartwatches, don’t measure heart rate precisely enough. This is a bit of a bummer if you’re relying on them for serious health monitoring.
I did some digging, and it seems the accuracy varies wildly depending on the brand, model, and even your skin tone. Some watches perform better than others, but generally, if you need precise heart rate data, a dedicated medical-grade device is recommended. Think of it like buying clothes online – sometimes you get exactly what you expected, other times… not so much. Smartwatches are great for general fitness tracking, but for precise medical information, they’re not quite reliable enough yet.
What are the drawbacks of smartwatches?
So, you’re thinking about smartwatches? Great! But let’s be real, there are some downsides to consider before clicking “buy.”
Inaccurate Data: This is a BIG one. While many fitness trackers boast impressive features, studies show that up to 80% of data – things like calories burned and heart rate – can be inaccurate. I’ve personally experienced this – my smartwatch told me I burned 1,000 calories on a walk, which is just…not believable. Always take the data with a grain of salt and don’t rely on it for precise medical-grade information.
Limited Battery Life: This is another major drawback. Most smartwatches need charging every one to two days. Imagine forgetting to charge it before a long hike or a weekend trip – you’ll be left with a very expensive paperweight. Some models last a little longer, but expect to find yourself constantly plugging it in.
Other things to think about before buying:
- Compatibility: Check if the smartwatch is compatible with your smartphone’s operating system (Android or iOS). Incompatibility can severely limit functionality.

Here’s the breakdown for your peace of mind:
- Non-ionizing radiation: Smartwatches use radio waves, which are non-ionizing. This means they don’t have enough energy to damage DNA, unlike ionizing radiation (like X-rays).
- Research backs it up: Multiple large-scale studies haven’t found a link between low-level non-ionizing radiation and serious health issues. You can easily find these studies online if you’re a total research nerd.
- Comparison is key: Smartwatches emit significantly less radiation than other everyday devices like microwaves or cell phones. So it’s really not a huge concern.
Now, go forth and conquer your fitness goals with your fabulous new smartwatch, worry-free!
Who shouldn’t wear smartwatches?
As a frequent buyer of smart gadgets, I’ve learned that while smartwatches, smart rings, and even smart scales offering fitness tracking are fantastic, they’re not for everyone. Crucially, you should avoid using these devices if you have a CIED, ICD, or CRT – that’s a cardiac pacemaker, implantable cardioverter-defibrillator, or cardiac resynchronization therapy device. The electromagnetic interference from these wearables can potentially disrupt the function of these life-saving medical implants. This interference isn’t always obvious; it can manifest as erratic readings or even malfunctioning of the implanted device.
It’s not just about the watch itself. Even the sensors in smart scales, which may seem innocuous, still emit electromagnetic fields, though generally weaker than a smartwatch. The cumulative effect of multiple devices could become problematic. Always check with your cardiologist or the manufacturer of your implanted device for specific guidelines. They can advise on safe distances, compatible devices (if any exist), and potentially necessary precautions. Ignoring this advice could have serious health consequences.
Manufacturers are improving compatibility, but for now, err on the side of caution. If you have an implanted cardiac device, prioritize your health over the convenience of a fitness tracker. There are other ways to track your activity.

How accurate are smartwatch readings?
Smartwatches offer a convenient way to track your blood pressure, but their accuracy shouldn’t be taken for granted. The technology used in smartwatches is significantly less precise than that found in medical-grade blood pressure monitors. Expect a margin of error; individual smartwatch accuracy varies, but a 15-20% deviation isn’t uncommon. This means the readings should be considered estimates rather than definitive medical data.
Several factors contribute to this inaccuracy. Smartwatches typically use optical sensors that measure blood flow changes in your wrist, while medical devices utilize inflatable cuffs that directly measure pressure in the brachial artery. This fundamental difference in measurement methods leads to inherent limitations in smartwatch readings.
Movement, improper placement of the watch, and individual variations in skin tone and blood vessel structure can all further impact the accuracy of smartwatch readings. Additionally, the algorithms used to interpret the optical sensor data vary between manufacturers and device models, leading to inconsistent results.
While smartwatches can provide a general overview of blood pressure trends, they shouldn’t be used to diagnose or manage hypertension. Always consult a healthcare professional and use a validated medical device for accurate and reliable blood pressure measurements, especially if you have pre-existing conditions or suspect hypertension.
For accurate blood pressure monitoring, consider investing in a validated home blood pressure monitor. These devices are inexpensive, easy to use, and provide significantly more reliable results compared to smartwatch readings. Regular, accurate blood pressure monitoring is crucial for maintaining cardiovascular health.
