# Are Fitness Trackers Making Us Healthier? A Comprehensive Exploration of the Advantages and Disadvantages of Technology

Throughout the majority of human history, individuals depended on their senses to assess their physical well-being. Hungry? Eat. Tired? Rest. Out of breath? Slow down. Nonetheless, in today’s world, wearable fitness devices have emerged to offer real-time, data-driven evaluations of our health.

Now, with a quick glance at our wrists, we can monitor our heart rates, step counts, calories burned, sleep quality, and even blood oxygen saturation. Some of these metrics align with our feelings, while others present unexpected revelations—like those additional 500 calories sneaking in through barbecue sauce.

In the best instances, **fitness trackers serve as a link between our subjective impressions and objective facts.**

This distinction is vital because, although self-evaluation is valuable, humans often struggle to accurately assess their experiences. But to what extent should we depend on these devices? And can we enhance our innate ability for self-monitoring?

In this piece, we’ll explore:
✅ **The true accuracy of fitness trackers**
✅ **When tracking benefits us (and when it doesn’t)**
✅ **Ways to cultivate better self-awareness through cautious technology use**

Let’s begin.

## What is the Accuracy of Fitness Trackers?

Before placing trust in a device for health guidance, it’s important to **recognize its limitations**.

Fitness trackers are generally reliable for measuring specific metrics—such as number of steps, heart rate, and sleep patterns¹—while other data points, like calorie burn and recovery status, tend to be significantly less precise.

Here’s the reasoning:

– **Steps and heart rate:** These metrics can be easily measured with accelerometers and optical sensors, and most fitness trackers perform well in capturing these with minor error margins.
– **Calories burned:** This depends on algorithms that use generalized data and estimates, leading to **considerable inaccuracies** for many individuals due to their unique metabolic differences.
– **Sleep tracking:** While devices can monitor movement and heart rate to estimate different sleep stages, they **cannot substitute for a clinical sleep study** in identifying sleep disorders.

Thus, while current fitness wearables can yield valuable insights, they should not be deemed infallible.

## When Is Tracking Beneficial?

Fitness trackers give us more data than ever. **But is having more data necessarily advantageous?**

Samantha Kleinberg, a decision-making researcher, indicates that **even small increments of extra information can complicate decisions rather than simplify them**².

Insufficient data might leave you unaware, whereas excessive data can be overwhelming. The ideal scenario? **Tracking that facilitates better choices and enhances your well-being.**

Here are **three indicators** to determine if your tracking practices are truly beneficial:

🔹 **Sign #1: Tracking reduces your stress and affirms your progress.**
📉 If tracking provides reassurance by demonstrating that your diet or exercise plan is effective (e.g., a lower resting heart rate from Zone 2 cardio), it can **boost motivation and maintain consistency**.

🚨 **Caution:** If daily tracking heightens stress—like compulsively checking a sleep score as a sleep-deprived parent—it could be counterproductive.

🔹 **Sign #2: Tracking boosts motivation and supports behavioral changes.**
If **immediate feedback encourages** you to make healthier choices (e.g., forgoing a second glass of wine after realizing its negative effects on your sleep), tracking can be an effective self-improvement aide.

🚨 **Caution:** If tracking **distracts you from enjoying an activity**—such as shifting weekend biking into a competition instead of a pleasurable experience—it may be time to reassess your data usage.

🔹 **Sign #3: Tracking aids you in *gaining a deeper understanding of yourself***
For instance, many individuals **overrate** the intensity of their workouts, while others **underrate** their physical capabilities. Effective tracking can **help reconcile these perceptions**, leading to enhanced training results.

🚨 **Caution:** If tracking **causes a disconnect from your instincts**, that’s a concern. An example? Some individuals lose touch with their natural hunger/satiation signals when they start relying *solely* on calorie tracking applications.

## How to Utilize Technology to Enhance Your Self-Assessment

Tracking devices are here to stay, but human intuition and perception remain crucial for optimizing health. Here’s how you can refine your self-assessment skills while still leveraging technology judiciously:

### 1️⃣ Reflect on your feelings before checking the metrics.

Rather than instantly reviewing data, **take a moment to connect with your own physical sensations first.**
