The article highlights the capabilities and limitations of wearable technology for health tracking: 

​

• 📈 Wearables excel at step counting and heart rate monitoring, providing useful insights into daily activity and cardiovascular trends, although they may not always be precise.

• 🛌 Sleep tracking has improved, yet devices only infer sleep stages based on movements and heart rate, making their accuracy less reliable compared to clinical studies.

​

• ⚠️ While these devices offer significant data, they can lead to a false sense of certainty, especially regarding calorie counts, which are often estimated rather than accurately tracked.

​

• 😟 Constant self-monitoring can cause anxiety and diminish intrinsic motivation, with users potentially becoming obsessed with numbers rather than enjoying healthy habits.

​

• 🧠 To maximize benefits, use wearables as supportive tools, focusing on trends and personal feelings while consulting professionals when needed for health concerns.
