How Watching TV Changed My Heart Rate (and What It Revealed About Your Nervous System)

Ever notice your heart rate spike for no obvious reason? Here’s what I discovered on the treadmill and why it matters for your health.

During my morning workout, I noticed something strange. My heart rate monitor showed a jump from Zone 3 to Zone 4 as soon as I started watching TV.

At first, I thought it was just excitement from the show, but then I realized I had tilted my head slightly to look up at the screen. That small change in posture altered how my body moved and how my nervous system responded.

This small observation reminded me of what I look for in my office through HRV, EMG, and Thermography testing:

• HRV (Heart Rate Variability) shows how your body adapts to stress.

• EMG tracks how your muscles are working and compensating.

• Thermography reveals patterns of tension or imbalance in your nervous system.

Tiny shifts like changing your head position can create big differences in how your body functions. These tests help uncover what your body is saying before it becomes pain.

If you’ve been feeling off or just want to understand your body better, we can measure exactly how your nervous system is adapting.
