Chronic fatigue can be discouraging—especially when you’re doing “all the right things” and still wake up tired, struggle to focus, or feel like your recovery tank is always running low. Dr. Linette Williamson, MD offers an integrative and functional medicine approach for patients near Rancho Santa Fe who want a more complete, root-cause look at fatigue and a plan designed around their body, lifestyle, and goals.
At Dr. Williamson’s practice, fatigue care is individualized, evidence-informed, and systems-based. Rather than chasing symptoms with a one-size-fits-all protocol, the focus is on identifying what’s driving your low energy—then building a realistic plan you can follow. For some patients, that plan may include non-invasive light therapy as a supportive, in-office option to help encourage healthier cellular signaling and recovery capacity.
Living with chronic fatigue can affect nearly every part of daily life: your energy, focus, motivation, ability to exercise or bounce back, and even your mood and sense of resilience. That’s why Dr. Williamson emphasizes a steady, safety-first path forward that prioritizes consistency and measurable progress. Improvement is personal—some people notice changes sooner, while others progress more gradually as underlying factors are addressed.
What Is Non-invasive Light Therapy?
Non-invasive light therapy is an in-office wellness modality that uses specific wavelengths of light applied to the body in a controlled, comfortable setting. The goal is to support the body’s natural recovery processes through cellular signaling—especially pathways involved in energy production, circulation support, and resilience.
This is not the same as:
- Tanning beds, which use ultraviolet light and are designed to darken skin
- Heat lamps, which primarily provide warmth
- One-size-fits-all home gadgets, which vary widely in quality, wavelength accuracy, and dosing consistency
In an integrative medical setting, light therapy is selected and paced based on how you respond—especially if fatigue is accompanied by sensitivity, headaches, sleep disruption, or fluctuations in stamina.
Types of non-invasive light therapy used in integrative settings
You may also hear light therapy described as photobiomodulation, a term commonly used for light-based approaches intended to influence cellular function without heat or invasive procedures. In practical terms, integrative light therapy is often delivered in one of two ways:
- Whole-body applications: designed for broad support when fatigue feels systemic
- Targeted applications: focused on areas associated with tension patterns, recovery needs, or specific symptom clusters
Another important distinction is in-office systems vs. consumer devices:
- In-office therapy is typically more consistent in wavelength output and dosing, with guidance on pacing and monitoring.
- Consumer devices can range from helpful to ineffective, depending on build quality, light specifications, and how they’re used.
At Dr. Williamson’s practice, advanced, non-invasive light options may be incorporated into a broader functional plan when appropriate, including devices such as TheraLumen and HemaLumen.
Why patients seek light therapy for fatigue
Patients near Rancho Santa Fe often explore non-invasive light therapy because it fits into real life: it’s comfortable, non-invasive, and can be paired with lifestyle and functional medicine strategies. The most common goals include:
- Support for energy and recovery: helping the body rebuild resilience rather than pushing through depletion
- Support for mental clarity and daytime function: improving how you feel as you move through work, family life, and commitments
- Support for stress resilience and overall vitality: especially when fatigue overlaps with stress load, disrupted sleep, or a sense of “running on empty”
For many patients, the value is not in a single session, but in consistent care—where light therapy is one piece of a comprehensive plan designed to address the drivers of fatigue and track progress over time.
How Light Therapy May Support Chronic Fatigue
Cellular energy and mitochondria support
Many people with chronic fatigue describe a “low battery” feeling—like your body can get through the day, but with less reserve, slower recovery, and more effort for the same tasks. One reason fatigue can feel so persistent is that energy happens at the cellular level, largely through structures called mitochondria, which help convert nutrients and oxygen into usable energy.
Non-invasive light therapy is often discussed in integrative care because specific wavelengths of light may help support cellular signaling involved in energy-related processes. Rather than forcing stimulation, the goal is to encourage healthier function and resilience so your body can produce and manage energy more efficiently over time.
Circulation and recovery support
When fatigue is tied to poor recovery—after workouts, busy weeks, travel, or stress—circulation and tissue support can matter. In integrative models, light therapy is commonly used with the intention of supporting microcirculation and the body’s natural repair processes.
Recovery capacity influences fatigue patterns in a practical way: if your body has a harder time “resetting” after physical or mental demands, you may notice more crashes, longer bounce-back time, and reduced stamina. Supporting recovery can be a meaningful part of a chronic fatigue plan, especially for patients balancing a full schedule in Rancho Santa Fe and surrounding areas.
Nervous system and stress physiology support
Chronic fatigue frequently overlaps with the fatigue–stress–sleep loop:
- Stress signaling increases tension and drains recovery bandwidth
- Sleep becomes lighter or less restorative
- Daytime fatigue grows, and the body relies on adrenaline or caffeine to keep going
- The cycle repeats
Non-invasive light therapy can be incorporated as part of a broader plan that supports nervous system regulation and resilience. When paired with consistent sleep strategies, stress support, and nutrition that stabilizes energy, many patients find it easier to build steadier momentum instead of riding the peaks and crashes.
Inflammation balance support
Fatigue often shows up alongside inflammation patterns—body aches, heaviness, brain fog, or a sense of being run down. In integrative care, light therapy is commonly used as a supportive option within an inflammation-aware plan that also addresses the most common drivers of inflammatory load, such as sleep disruption, gut imbalance, metabolic stress, nutrient gaps, and chronic stress physiology.
Non-invasive Light Therapy Options at Dr. Linette Williamson’s Practice
In-office advanced light devices
At Dr. Linette Williamson, MD’s practice near Rancho Santa Fe (Encinitas), non-invasive light therapy may include advanced in-office devices such as TheraLumen and HemaLumen. Sessions are designed to be comfortable and straightforward.
A typical visit generally includes:
- A brief check-in on symptoms, sleep, and recent recovery
- A guided, non-invasive light application in a supervised setting
- A plan for pacing and follow-up based on how you respond over time
How Dr. Williamson chooses the right approach
Dr. Williamson matches the method to your specific fatigue pattern and overall health picture, including:
- Your goals (energy, clarity, stamina, recovery, resilience)
- Sensitivities (light sensitivity, headache patterns, sleep disruption)
- Schedule realities (what you can do consistently)
- The functional drivers identified in your evaluation (sleep, stress physiology, hormones, gut health, nutrient status, metabolic patterns)
Combining light therapy with other integrative supports
Non-invasive light therapy is often most helpful when it’s part of a complete fatigue strategy. Dr. Williamson may coordinate light therapy with supportive care such as:
- Nutrition and metabolic support to stabilize energy and reduce crashes
- Sleep optimization and recovery planning
- Stress physiology support to improve resilience and restore steadier rhythms
- Gut and digestive support when symptoms or history suggest it’s contributing
- Hormone evaluation and balance when clinically indicated
- Additional in-office therapies offered at the practice, such as hyperbaric oxygen therapy and advanced integrative therapies, when appropriate for your care plan
Measuring progress
Dr. Williamson emphasizes measurable progress so you’re not guessing whether things are improving. Common tracking points include:
- Energy levels throughout the day
- Sleep quality and how refreshed you feel in the morning
- Stamina and recovery time after activity
- Brain fog, focus, and mental clarity
- Mood and stress tolerance
Whole-Person Support for Better Energy and Resilience
At Dr. Linette Williamson, MD’s practice, chronic fatigue care is guided by a simple, steady philosophy: personalize, measure, and adjust.
