You’re Not Stiff—You’re Blue Light Toxic!
You've tried everything—foam rolling, yoga, mobility drills, chiropractic care, physiotherapy, even acupuncture—and yet, your body still feels tight, immobile, and stuck. Sound familiar?
If your range of motion hasn’t improved despite all your best efforts, it might be time to shift your focus away from your body and look toward a lifestyle factor that's hiding in plain sight: your light environment!
Light influences every single cell of your Body:
Most people think of light simply as a way to brighten a room. But light is a biological signal that directly affects our nervous system, metabolism, and tissue health. The kind of light we’re exposed to—especially in today’s world of constant screen use and artificial lighting—has a profound impact on how our bodies function and feel.
One of the biggest culprits? Artificial blue light.
Blue Light and Mitochondrial Dysfunction
Blue light isn't inherently bad—it’s a natural part of sunlight. But when it's isolated and chronic, as it is in artificial lighting from screens, LEDs, and fluorescent bulbs, it becomes a problem. One of the ways it damages our health is by disrupting mitochondrial function.
Specifically, blue light can inhibit cytochrome c oxidase, a crucial enzyme in the mitochondrial electron transport chain. This chain is how our cells produce ATP—our body’s energy currency (Wang et al., 2016). When this enzyme is inhibited, not only is energy production compromised, but the formation of structured (exclusion zone) water inside cells is also impaired. This structured water is essential for maintaining tissue hydration, elasticity, and optimal function (Pollack, 2013).
Light, the Nervous System, and Fascial Tension
Exposure to artificial blue light keeps us stuck in a sympathetic (fight or flight) nervous system state. This has a ripple effect on our muscle tone and fascial tension. When muscles are subtly and chronically contracted due to stress, they pull on the fascial network—a continuous web of connective tissue that wraps around and through every muscle and organ in the body (Schleip et al., 2012).
Just like a fitted sheet that's been tugged too tight on one corner, this fascial tension can create a sensation of stiffness, restrict mobility, and even cause pain—no matter how much you stretch or roll it out.
The Healing Power of Sunlight
On the other hand, full-spectrum Sunlight does quite the opposite!
• Stimulates cytochrome c oxidase, boosting mitochondrial function and energy production (Wong-Riley et al., 2005)
• Promotes the production of structured water, aiding in tissue elasticity (Pollack, 2013)
• Encourages a parasympathetic (rest and digest) nervous system state, helping muscles and fascia relax (LeGates et al., 2012)
• Enhances mood, immune function, and circadian rhythm regulation (Holick, 2008)
In short, natural light helps your body relax, hydrate, and move better—at a deep, cellular level.
Takeaway: Fix Your Light, Free Your Body
Next time you’re about to grind through a foam rolling session or stretch out those tight hips, take a moment to ask: What kind of light am I doing this under & living under?
We personally block all artificial blue light throughout the entire day and night as much as we can by wearing blue light blocking glasses, using warm/red lighting after sunset, and minimizing all tech use at least 3 hours before bed. Most importantly, we get outside during the day to soak up that full-spectrum sunlight and try to do as many of our activities outside grounded to earth as much as we can ⚡
