Just a few years ago, wearing a smartwatch seemed like something reserved for athletes or tech enthusiasts. Today, millions of people use smartwatches, bracelets, and rings to monitor their health in real time. And behind this trend lies much more than fashion or convenience: there is a gigantic business based on biometric data and artificial intelligence.
These so-called wearables have gone from counting steps to becoming veritable personal laboratories. A simple watch or ring can measure heart rate, blood oxygen levels, sleep quality, stress, body temperature, and even detect possible cardiac irregularities. Some devices are already beginning to offer alerts about hypertension, sleep apnea, or early signs of cardiovascular disease.
The big promise is very powerful: "This device could save your life." And, frankly, it's a difficult argument to ignore.
More and more people are willing to spend a few hundred euros on a device that helps them monitor their health 24/7. Especially after a certain age, the feeling of control and prevention has enormous emotional value. It's no coincidence that tech giants like Apple, Alphabet, Samsung, Huawei, and Garmin are investing billions in this sector.
The figures perfectly explain the interest. The global wearables market continues to grow strongly and already generates more than $125 billion annually, driven by digital health and personal monitoring. Furthermore, analysts predict that growth will continue in the coming years thanks to the integration of artificial intelligence and subscription services associated with these devices.
And here lies one of the most interesting aspects of the business: the real value isn't just in selling smartwatches or rings. The true treasure is the user data.
Each user generates thousands of biometric data points daily: heart rate, sleep patterns, activity levels, stress, exercise habits, diet, and even emotional states. All this information, analyzed using AI, allows for the identification of patterns and the making of predictions about a person's future health. For technology and pharmaceutical companies, this information is invaluable.
Imagine millions of users sharing anonymous data about sleep, physical activity, and cardiovascular diseases. This database could help develop medications, personalized health insurance, or predictive health systems. The problem is that very few users are truly aware of the extent to which they are sharing extremely sensitive information.
The important question is not only what these devices can do, but who controls the data and how it is used.
Europe has relatively strict privacy laws, such as the GDPR, but the speed at which technology advances often outpaces the ability of legislators to react. Meanwhile, tech companies continue to expand their digital ecosystems around health.
In fact, the business no longer revolves solely around hardware. Companies are seeking recurring revenue through premium apps, cloud storage, advanced analytics, and personalized health services.
The popularity of these devices is also receiving a huge media boost. In some tennis tournaments and sporting competitions, athletes are already allowed to use wearables to monitor physical parameters during training and recovery. Seeing elite athletes using smart rings or watches generates a very powerful advertising effect: if professionals use them to take care of their health, why shouldn't we?
And therein lies the key to success: these devices combine technology, medical prevention, and peace of mind. And that sells very easily.
Personally, I believe that wearables can provide real benefits, especially for older people or patients with certain medical conditions. Early detection of heart problems or sleep disorders can make a significant difference.
But I also believe we must demand absolute transparency regarding the use of our biometric data. Because when a company knows our physical condition, our habits, and even our stress levels, the product is no longer just us: it's also our information.
While users continue to be delighted with new gadgets that make our lives more convenient, Big Tech continues to consolidate ever-increasing economic and social power.
And everything indicates that this is just the beginning.
