# While Our Forebears Relied on Their Senses to Gauge Their Wellbeing, We’re Growing More Dependent on Devices

The human experience has seen remarkable transformation. Historically, our forebears tuned into their inherent senses to assess their wellbeing—trusting their instincts to gauge hunger, readiness for physical activity, and even the quality of their rest. Nowadays, a significant number of us are shifting away from these internal signals towards a more measurable approach, largely fueled by cutting-edge devices.

It is now feasible, often via a single wearable gadget, to monitor heart rate, step count, exercise intensity, sleep quality, and additional metrics. These technological wonders promise to connect subjective feelings with objective data, providing tools to enhance our self-awareness and improve our health. Yet, despite their empowering nature, they bring about their own set of challenges and inquiries regarding dependency, precision, and balance.

So, how precise are these advanced trackers? Should we depend entirely on them, or is there still merit in tuning into our own perceptions? And, importantly, are there ways to integrate technology into our lives while continuously honing our natural capability to evaluate ourselves?

Let’s delve into these themes, examining where technology aids, where it may hinder, and how you can adopt it in a balanced manner.

## How Precise Are Fitness Trackers Really?

Let’s clarify one thing: not all trackers—or the data they yield—are on par. The effectiveness of a fitness tracker hinges on a blend of its hardware, software, and the datasets available for its algorithms to utilize. Certain metrics, such as **heart rate** or **step count**, are generally quite reliable. Nevertheless, other measurements, like calories burned or movement velocity, frequently exhibit considerable discrepancies from actual values.

For example, while your smartwatch may assert you burned 500 calories in a workout, research indicates that calorie estimates can vary by as much as 27-93%. That’s a substantial margin of error! Activity-based metrics can also be plagued by inconsistencies, especially if the algorithms misinterpret actions (e.g., confusing typing for walking).

### What This Implies for You
For metrics that are challenging to quantify accurately, treat your tracker as a guide rather than absolute truth. It still provides valuable information but shouldn’t necessarily dictate your health-related choices. (For a thorough exploration of the reliability of particular progress indicators, consult this detailed resource.)

## When Is Monitoring Beneficial (And When Isn’t It)?

Fitness devices offer us greater insights into our behaviors and bodies than we’ve ever experienced. That’s undeniably thrilling, but it also presents the issue of “too much information.” Samantha Kleinberg, a computer scientist with a focus on decision-making, articulates the paradox well: “Even a small amount of surplus information has a significant negative effect on our decision-making.”

Monitoring is most beneficial when it delivers **clear, actionable feedback**. Conversely, it becomes a hindrance when it overwhelms or stresses us, especially when we become fixated on metrics that don’t significantly contribute to health or performance improvements.

### The Inverted U of Data Management
Visualize an inverted U-curve representing the balance of information. At the apex of the curve, you find the “sweet spot”—enough data to make informed choices but not so much that you end up paralyzed by analysis. Too little or too much information pushes you down either side of the curve, resulting in suboptimal outcomes.

## Indicators That Tracking Is (Or Isn’t) Benefiting You

Unsure whether your fitness tracker is a helpful tool or is beginning to induce stress? Reflect on these indicators:

### **Indicator #1: Tracking reduces stress and boosts your confidence.**
Zak, a dedicated runner, found it difficult to believe that “easy” zone 2 cardio could be effective. However, utilizing a heart rate monitor led him to witness tangible improvements, such as a lower resting heart rate and quicker recovery times. This objective confirmation helped Zak trust his training regimen.

**When tracking reinforces your methods or inspires you to maintain consistency, it’s a positive influence.** However, if it creates additional anxiety—like the new parent distressed by a sleep score they can’t control—it may be wise to take a step back.

### **Indicator #2: Tracking increases your motivation and capabilities.**
Data is most beneficial when utilized as a catalyst for taking meaningful action. Take Margaret, for instance, who employed a sleep tracker and discovered that consuming wine before bedtime negatively influenced her rest. With that insight, she made lifestyle changes that enhanced her overall wellbeing.

Conversely, tracking can have adverse effects. Jan, a casual cyclist, became fixated on chasing performance metrics obsessively, prioritizing trail times over enjoyment. The emphasis on numbers ultimately led to burnout, erasing the joy of the activity.
