Chronic fatigue can be hard to explain to people who haven’t lived it. It’s not just “tired.” It can feel like your body battery never fully charges—no matter how early you go to bed, how many supplements you try, or how much you push through your day. Simple tasks can feel unusually demanding. Work meetings require more focus than they used to. Exercise can backfire. Even social time—something you want to enjoy—can feel like it costs more energy than you have.
When you’re already depleted, adding “one more hard thing” to your routine can feel impossible. That’s why many people explore non-invasive approaches that are comfortable, low-stress, and designed to work alongside a broader plan. Non-invasive light therapy (often called red light therapy, near-infrared light therapy, or photobiomodulation) is one option that may support recovery and energy—without needles, downtime, or intense interventions.
Dr. Linette Williamson, MD offers an integrative approach to fatigue care for patients near Del Mar and throughout the surrounding San Diego area. The goal is to help you feel more steady, resilient, and clear—by combining supportive therapies with a thoughtful look at what may be driving your fatigue in the first place.
What Is Non-Invasive Light Therapy?
Non-invasive light therapy uses specific wavelengths of therapeutic light applied externally to support cellular function and recovery. Many people first hear about it as red light therapy or near-infrared (NIR) light therapy, and in clinical settings you may also see the term photobiomodulation (PBM).
In plain language: the right light, delivered in the right way, may help your cells respond more efficiently—particularly in systems involved in recovery, inflammation balance, circulation support, and stress resilience.
How it differs from heat therapy, UV exposure, or tanning devices
This is an important distinction:
- It’s not heat therapy. While some people feel mild warmth, the intention is not to “heat tissue” the way a sauna or heating pad does.
- It’s not UV light. UV is the wavelength range associated with tanning and sunburn risk. Therapeutic red/NIR light is different and is not intended to tan the skin.
- It’s not a cosmetic tanning device. Clinical light therapy targets supportive wellness and recovery pathways, not pigmentation changes.
What “non-invasive” means for patients
Non-invasive means the therapy is delivered externally, typically with comfortable positioning and minimal disruption to your day. There’s no anesthesia, no incision, and no typical “downtime.” Many people incorporate sessions into a broader care plan that also addresses sleep, stress, nutrition, and underlying contributors.
How Light Therapy May Support Chronic Fatigue
Cellular energy support through mitochondrial signaling
Your mitochondria are often called the “energy factories” of your cells because they play a key role in producing ATP—the body’s usable energy currency. In photobiomodulation research, red and near-infrared light are often associated with supporting mitochondrial signaling, which may help cells function more efficiently.
What this can mean in real life:
- A steadier baseline of energy
- Less “wired but tired” variability
- Improved resilience when you’re trying to return to normal routines
Support for inflammation modulation and recovery
Many chronic fatigue patterns overlap with inflammation and immune stress—sometimes obvious, sometimes subtle. Light therapy is often used with the intention of supporting the body’s recovery response and helping modulate inflammatory signaling.
This doesn’t mean “turning inflammation off” (inflammation is part of healing), but rather supporting a healthier balance so you can recover more normally—especially after stress, poor sleep, illness, or exertion.
What patients may notice when recovery improves:
- Less prolonged soreness or heaviness
- Fewer crashes after busy days
- A smoother return to activity
Support for circulation and tissue oxygen utilization
Many people with fatigue describe feeling “draggy,” heavy, or slow to recover after exertion. Light therapy is frequently discussed in the context of microcirculation support (how blood moves through smaller vessels) and tissue-level recovery.
When circulation and oxygen utilization are better supported, some patients report:
- Improved stamina for everyday tasks
- Less fatigue buildup throughout the day
- A greater sense of physical “ease” during movement
Support for nervous system balance and stress recovery
Chronic fatigue often lives alongside nervous system overload—high stress, poor sleep, anxious energy, or feeling like your body can’t “downshift.” Light therapy sessions are commonly described as calming, which may support a more regulated nervous system state.
When your nervous system is better supported, you may notice:
- Improved stress tolerance
- Fewer adrenaline-like surges
- More stable energy (less boom-and-bust)
- An easier time winding down at night
Potential supportive effects on sleep quality and mental clarity
Sleep quality and mental clarity are two of the most common “secondary wins” patients hope for when addressing chronic fatigue. Since photobiomodulation is often approached through the lens of recovery support and nervous system regulation, it may be used with goals like:
- Falling asleep more easily
- Sleeping more deeply
- Waking with slightly more restoration
- Reduced brain fog and improved focus

TheraLumen: What It Is and How It’s Commonly Used
TheraLumen is an advanced, non-invasive light therapy device that delivers therapeutic wavelengths of light to support cellular recovery and resilience. In supportive wellness plans, TheraLumen is often used to help patients who are experiencing:
- Low energy and reduced stamina
- Brain fog and reduced mental clarity
- Stress-related depletion
- Slow recovery after activity
- Difficulty “bouncing back” despite good intentions and lifestyle changes
Sessions are designed to be comfortable and low-demand, making it a practical option for people who feel like they don’t have the bandwidth for more aggressive interventions.
HemaLumen: What It Is and When It May Be Considered
HemaLumen is another advanced light-based option that may be considered when fatigue patterns suggest a need for deeper recovery support. It may be incorporated into a fatigue-focused protocol when the care plan is targeting:
- More persistent or complex fatigue patterns
- Slower recovery capacity and resilience
- Support for whole-body restoration goals as part of an integrative strategy
HemaLumen is selected based on your history, symptom pattern, and how your body is responding to your overall plan.
What to Expect: Your Light Therapy Visit
Initial intake and symptom mapping
Your visit begins with a detailed review of:
- Energy patterns across the day
- Sleep quality and consistency
- Stress load and recovery capacity
- Nutrition and hydration habits
- Medical history and current medications/supplements
Goal setting
You and Dr. Williamson will define what “better” means for you. Common goals include:
- More stable energy
- Improved mental clarity
- Better sleep quality
- Improved recovery after activity

Session experience
During treatment, most patients find the experience relaxing. You’ll be positioned comfortably in a supportive environment. Sensations vary, but many people report minimal sensation beyond mild warmth or a calming feeling.
Aftercare guidance
After your session, you may receive recommendations such as:
- Hydration and electrolyte support
- Gentle movement and recovery-friendly routines
- Sleep support habits
- Tracking changes in stamina, sleep, brain fog, and post-activity recovery
How progress is measured
Progress is typically evaluated using real-life improvements such as:
- More consistent energy throughout the day
- Improved tolerance to activity without major crashes
- Reduced recovery time after exertion
- Clearer thinking and improved sleep quality
Take the Next Step Toward Steadier Energy
If you’ve been dealing with persistent fatigue, it’s not “just stress,” and it’s not something you have to keep powering through alone. When your energy is consistently low—especially when rest doesn’t restore you—it deserves a thoughtful evaluation and a plan that’s tailored to your body, your lifestyle, and your goals.
Non-invasive light therapy can be a supportive tool for many patients dealing with chronic fatigue, particularly when it’s part of a broader integrative strategy. By combining gentle, technology-forward therapies with personalized medical insight, nutrition support, hormone optimization when appropriate, and recovery-focused planning, the goal is to help you rebuild energy, resilience, and recovery capacity over time.
If you’re in Del Mar or the surrounding San Diego area and you’re ready for a next step, schedule a consultation to review your symptoms and determine whether non-invasive light therapy is the right fit for your fatigue support plan.
