Wearables and the impact of smartwatches on our health

In recent years, wearables—portable electronic accessories like smartwatches, fitness trackers, and other intelligent devices (such as rings and glasses)—have surged in popularity. These connected gadgets are primarily used by individuals looking to track their physical activity, monitor their health, or improve their overall well-being. While these technologies undoubtedly offer numerous advantages, they also come with certain risks that are important to understand.

Data tracking as a core feature

Tracking physical activity and boosting fitness

Wearables are powerful tools for monitoring various aspects of daily activity. Common metrics include step count, calories burned, and time spent exercising. These devices can also provide more detailed measurements during workouts, such as heart rate, average speed, and duration of effort. The ability to visualize this data can motivate users to engage in regular physical activity. In this sense, wearable technology can be a strong motivator for maintaining a consistent fitness routine.

Monitoring cardiovascular health

Wearables allow users to track several cardiovascular health indicators, like heart rate. However, it’s important to note that the data provided by these devices is not always accurate. Metrics like calories burned or steps taken can offer a general overview of physical activity but should not be used as a medical reference. These tools are not designed for diagnosis or as substitutes for consultations with healthcare professionals. Instead, they provide a long-term overview of activity patterns.

Tracking sleep and mental well-being

Beyond physical activity, many wearables include features to monitor sleep quality by tracking light, deep, and REM sleep cycles. This data can help users better understand their sleep patterns and identify potential anomalies. Some models go a step further, offering advice to improve sleep quality, such as avoiding screens before bedtime or practicing relaxation exercises. Additionally, certain smart devices include tools aimed at enhancing mental well-being. For example, breathing exercises or heart rate variability tracking can help manage stress and promote relaxation.

Potential health risks

Despite their benefits, smart devices are not without risks. While generally considered safe, some studies suggest that prolonged exposure to electromagnetic waves from electronic devices could have long-term health effects. Excessive use of wearables may also lead to technology dependency, potentially altering one’s perception of their body or physical sensations. Furthermore, wearing these devices for extended periods can cause skin irritation or allergic reactions. These risks add to the broader health concerns associated with frequent use of modern technologies like phones and computers.

Psychological impacts and cybersecurity concerns

Getting caught up in the data these devices provide is easy, leading to worry when goals aren’t met, or sleep quality falls short. This performance-driven mindset can have psychological consequences, including anxiety. Users may feel obligated to constantly measure their performance, compare themselves to others, and monitor their mental state (such as anxiety or stress levels). Furthermore, gamification features intended to encourage activity might foster compulsive behaviours. Finally, wearables pose cybersecurity risks, as they typically collect significant amounts of personal data, including location and sensitive health information.

Like any technology, wearables come with both benefits and risks. The key is to use them mindfully, for the right reasons. Remember that they should never replace professional medical advice.
