Heart disease runs in my family. My dad underwent triple bypass surgery—a wake-up call that hit hard. It wasn’t just about his health; it was about our family’s future. It made me start paying closer attention to what’s happening inside my own body. I’m not just concerned about fitness or weight anymore—I’m focused on resilience, recovery, and reducing long-term cardiovascular risk. That’s how I ended up deep-diving into two powerful tools that may be working quietly behind the scenes: Heart Rate Variability (HRV) and Red Light Therapy (RLT).
Understanding HRV and Why It Matters
Heart Rate Variability (HRV) is the measure of the tiny fluctuations between heartbeats, controlled by the autonomic nervous system. A higher HRV generally reflects better adaptability, stress resilience, and parasympathetic (rest-and-digest) activity. A lower HRV often signals overtraining, chronic stress, poor sleep, or an imbalance between sympathetic (fight-or-flight) and parasympathetic nervous tone.
In short: HRV is a real-time window into how your nervous system is handling life—including stress, recovery, and cardiovascular strain.
For people with a family history of heart disease, like me, monitoring HRV is one way to get ahead of problems long before they become symptoms. It doesn’t replace imaging or diagnostics, but it gives daily insight into how lifestyle factors—sleep, training, nutrition, and recovery—are stacking up against inherited risk.
Red Light Therapy and the Nervous System
Enter red and near-infrared light therapy—a topic that came up in a fascinating conversation between Dr. Gabrielle Lyon and performance coach Joel Jamieson. Red light therapy is often known for improving skin tone, joint health, and muscle recovery, but it’s also gaining traction for its impact on nervous system regulation and HRV improvement.
How? At the cellular level, red light therapy:
Enhances mitochondrial function, allowing cells (including nerve cells) to produce more ATP (energy).
Reduces inflammation, especially in areas like the vagus nerve and cervical spine.
Supports blood flow and nitric oxide production, which helps with cardiovascular function.
All of this has direct effects on the parasympathetic nervous system—the part of our autonomic system that calms us down, slows heart rate, aids digestion, and promotes recovery.
What Joel Jamieson and Dr. Lyon Highlighted
In their podcast, Jamieson emphasized that HRV is not just a tool for athletes—it’s a proxy for healthspan and recovery potential. More importantly, they touched on how nervous system imbalances often go unaddressed in traditional medicine, especially when it comes to cardiac care.
Joel shared how chronic stress and poor autonomic balance can lead to subclinical issues that aren’t captured by standard bloodwork or even EKGs. Red light therapy, especially when applied consistently to the upper chest, neck, and spine, may help reset this balance by enhancing vagal tone—which in turn can raise HRV and promote cardiac resilience.
The Genetic Foreshadowing I Can’t Ignore
My dad’s heart problems didn’t start in his 70s. They were brewing decades earlier—manifesting as high cholesterol, creeping blood pressure, shortness of breath during activity. By the time he needed a triple bypass, the damage was done. But that doesn’t have to be my future.
Looking at his health history has shifted my focus from “fitness” to biological regulation—things like inflammation, nervous system tone, and cellular energy. These are all areas where red light therapy and HRV overlap.
By using daily HRV tracking through wearables like the Oura Ring or Whoop, I can see how my body is recovering—or not—from workouts, work stress, late nights, or illness. When my HRV dips, I know I need to step back, prioritize rest, maybe even do a 15-minute red light session to calm my system.
How I Use Red Light Therapy
Here’s what my current protocol looks like:
Daily morning session: 10–15 minutes of red/near-infrared light therapy (660nm and 850nm) on the chest, neck, and upper spine. This targets the vagus nerve and helps prime the parasympathetic system.
Evening wind-down: Occasionally, I’ll add a second short session if HRV has been low or if I’ve had a high-stress day. It helps transition into sleep.
Mobility + RLT combo: Doing light stretching, breathing exercises, or mobility work during red light therapy amplifies the calming effect and improves circulation.
I pair this with HRV trend monitoring—looking for 7-day averages and shifts rather than obsessing over daily spikes or dips.
The Research Is Catching Up
While red light therapy is still a growing field, studies have shown promising links between photobiomodulation and:
Reduced blood pressure through vasodilation
Improved HRV markers in athletes and chronically stressed individuals
Enhanced vagal tone and heart rate recovery after exercise
Lower inflammatory markers and oxidative stress
For people with a genetic predisposition to cardiovascular disease, this isn’t just biohacking—it’s a preventative wellness strategy rooted in science.
From Fear to Empowerment
Family history can feel like a ticking clock. But tools like HRV and red light therapy have helped me shift from passive worry to proactive care. Instead of waiting for symptoms, I’m tracking signals. Instead of guessing about stress, I’m measuring it.
Red light therapy may not reverse genetics—but it gives me a daily way to nudge my body toward balance, support my nervous system, and protect my heart.
Final Thoughts
If you have a family history of cardiac events like I do, I encourage you to look beyond traditional metrics like weight and cholesterol. Explore your nervous system health, your recovery capacity, and your HRV trends. Layer in red light therapy—not as a cure-all, but as a recovery tool—and you might be surprised how much calmer, more energized, and in control you feel.
Your genes may write the opening chapter, but the rest of the story is still yours to shape.
