The Healing Power of Red Light Therapy: How It Supports Your Brain, Skin, and Nervous System

If you've ever found yourself basking in the late afternoon sun and feeling an unexpected sense of calm wash over you, you’ve already had a hint of what red light therapy can do. This isn’t just about spa trends or shiny gadgets—red light therapy is a scientifically backed way to support your nervous system, enhance emotional balance, and nourish your skin at a cellular level.

In this post, I’m diving into the real science behind red light therapy—focusing especially on the nervous system and brain—and sharing the top five devices that are actually worth your investment. (And no, I don’t make a penny from sharing these—I just love doing the research so you don’t have to.)

What Is Red Light Therapy? A Quick Science Primer

Red light therapy (RLT), also known as low-level laser therapy (LLLT) or photobiomodulation, uses specific wavelengths of red (typically 630–660 nm) and near-infrared (NIR, 810–850 nm) light to stimulate mitochondrial function in your cells. This light penetrates deep into your tissues, where it interacts with the cytochrome c oxidase enzyme in your mitochondria.

Here’s the magic part: when red and NIR light hit your cells, they essentially recharge your mitochondria—your cellular batteries—boosting ATP (energy) production, reducing inflammation, and improving cellular communication.

Red Light and the Nervous System: A Calm Brain is a Resilient Brain

For those of us managing ADHD, anxiety, overstimulation, or the aftermath of chronic stress (hi, nervous system warriors!), red light therapy can be a powerful ally.

Here’s how red light therapy supports your nervous system:

1. Reduces Neuroinflammation: Chronic inflammation in the brain has been linked to depression, anxiety, cognitive fog, and neurodegenerative disorders. Red light therapy helps regulate microglial activation (your brain’s immune response), reducing inflammation and oxidative stress in the brain.

   
   

2. Boosts Mood and Emotional Balance: Studies show red and NIR light can increase the production of serotonin and dopamine—your feel-good neurotransmitters—by enhancing mitochondrial function in key areas of the brain like the prefrontal cortex. Some research even suggests it may help those with depression or PTSD.

   
   

3. Supports the Vagus Nerve and Parasympathetic Activation: Applying red light to the neck or upper chest (near the vagus nerve) can increase parasympathetic tone—shifting you from fight-or-flight into rest-and-digest. This can help lower heart rate, regulate digestion, and improve emotional resilience.

   
   

4. Improves Cognitive Performance and Focus: Clinical trials have demonstrated improvements in working memory, attention, and executive function after red light application to the forehead and scalp. Great news for ADHD brains and anyone working on mental clarity and emotional regulation.

   
   

Skin Deep… But Not Superficial: Red Light for Skin Health

While I like to focus on the nervous system, I’d be missing a major benefit if I didn’t mention how red light therapy supports the skin. It stimulates collagen production, reduces inflammation, speeds wound healing, and improves skin tone and elasticity.

This makes it a beautiful, side-effect-free way to support the nervous system and nourish the skin—especially helpful if you have skin flare-ups related to stress, like eczema or acne.

Other Health Benefits of Red Light Therapy:

• Reduces joint pain and stiffness

• Enhances muscle recovery post-exercise

• Improves sleep quality (when used in the evening)

• May support thyroid function (especially in Hashimoto’s)

• Helps regulate circadian rhythms

Red Light + Routine = Nervous System Magic

Here’s my suggestion for integrating red light therapy:

• Morning:Use a red light panel on your face, chest, or scalp while journaling or stretching. It can gently energize your mind and reduce inflammation from the get-go.

• Evening:Apply red light to the neck, chest, or behind the ears (vagus nerve area) before bed. This signals your nervous system to downshift and prepare for deep rest.

A Note on Safety

Red light therapy is considered very safe when used appropriately—avoid staring directly into the light and follow time recommendations (typically 10–20 minutes per area). Always talk to your healthcare provider if you have any concerns or medical conditions, especially if you're pregnant or managing a chronic illness.

Red light therapy is incredible, but it doesn’t work in a vacuum. In a future blog post (in the works- hopefully posted soon!), we’ll explore how nutrition can enhance mitochondrial function, emotional balance, and nervous system healing—including some surprising mood-boosting foods and supplements. (Spoiler alert: eggs, salmon, and dark chocolate are on the list.)
