Man the Red Light Therapy

Who Invented Red Light Therapy?

Ever wondered who sparked the glow-up trend of Red Light Therapy at Home? Short answer: NASA kicked it off—no joke! From space veggies to Red Light Therapy Panels and Beds, this tech has come a long way. Keep reading to discover how science met skincare (and muscle recovery)!

Man the Red Light Therapy

The Early Seeds of Light Therapy: From Ancient Discoveries to Modern Illumination

Understanding the Fundamentals of Light

Early Observations: Sunlight and Ancient Healing Practices

Long before science got involved, civilisations like the Egyptians, Greeks, and Romans turned to sunlight for healing. They understood its power to boost mood and aid health—even if they couldn’t explain why. Ancient temples even had sun rooms designed for therapeutic exposure.

Isaac Newton and the Spectrum of Light (1666)

In 1666, Newton made a breakthrough by splitting white light into colours using a prism. This discovery laid the foundation for understanding light as energy and its interactions with the human body. It was a turning point in how we see—and use—light.

The Advent of Artificial Light: Thomas Edison and the Electric Lightbulb (1879)

Edison’s invention of the electric lightbulb brought light indoors, changing human life forever. While he wasn’t targeting health benefits, his innovation made artificial light widely accessible. This would later pave the way for more targeted light-based technologies.


Pioneering Medical Applications of Light

Niels Ryberg Finsen: The "Father of Phototherapy" (Late 1800s – Early 1900s)

Danish physician Niels Finsen is considered the pioneer of medical light therapy. He began experimenting with focused light to treat skin diseases and chronic conditions. His work marked the formal birth of phototherapy.

Treatment of Lupus Vulgaris and Smallpox

Finsen’s use of concentrated light—especially ultraviolet—showed success in treating lupus vulgaris, a severe skin form of tuberculosis. Some early attempts also targeted smallpox, although less consistently. His methods brought real clinical impact.

Nobel Prize in Medicine (1903)

Finsen’s contributions were so revolutionary that he received the Nobel Prize in 1903. This official recognition validated light as a legitimate tool in medicine, sparking decades of curiosity and innovation.


The Birth of Modern Red Light Therapy: Key Inventions and Breakthroughs

The Laser and LED Revolutions

The Invention of the Laser: Theodore H. Maiman (1960)

In 1960, physicist Theodore Maiman created the first laser using a synthetic ruby. Though not intended for therapy, this opened the door to precise, controlled light applications across medicine and industry.

The Development of Light-Emitting Diodes (LEDs): Biard, Pittman, and Holonyak (Early 1960s)

Soon after, researchers like Biard, Pittman, and Holonyak introduced LEDs. These devices could emit specific wavelengths like red and near-infrared light. LEDs were safer, cheaper, and more accessible than lasers—perfect for future therapies.


The Accidental Discovery of Low-Level Laser Therapy

Dr. Endre Mester: The Hungarian Physician and His Unintended Findings (1967)

In 1967, Dr. Endre Mester of Hungary tried using low-powered lasers on mice to study cancer. The tumours didn’t shrink—but the mice grew more hair. This accidental result became the cornerstone of modern red light therapy.

Observations on Wound Healing and Hair Regrowth

Following this discovery, Mester found that low-level laser therapy helped wounds heal faster and stimulated tissue repair. He documented improved circulation and cell activity—all without harming the skin. A new field was born.


NASA’s Pivotal Role in Red Light Research

From Space Plant Growth to Human Healing (1990s)

In the 1990s, NASA used red and near-infrared light to help plants grow in space. They noticed side effects on astronauts—like faster wound healing. This unexpected benefit led to further human trials.

Advancements in Photobiomodulation (PBM)

NASA’s involvement propelled red light therapy into medical research. The concept of photobiomodulation (PBM)—light’s ability to modulate biological processes—became a focal point. This science underpins most Red Light Therapy Panels and Beds today.


The Evolution and Modern Applications of Red Light Therapy

Advanced Red Light Therapy

From Niche Treatment to Widespread Recognition

FDA Approvals and Clinical Validation (Early 2000s Onwards)

By the early 2000s, several red light devices gained FDA approval for specific conditions like joint pain and hair loss. Clinical trials began to support its safety and efficacy, helping to remove the “pseudoscience” label.

Growing Acceptance in Medical and Wellness Fields

Today, red light therapy is used across dermatology, physiotherapy, and even mental health care. Beauty clinics, gyms, and spas all offer sessions, and Red Light Therapy at Home has taken off too—thanks to user-friendly devices.


Key Mechanisms and Benefits of Red Light Therapy (Photobiomodulation)

Cellular Energy Production (Mitochondria and ATP)

Red light penetrates cells and stimulates mitochondria, the cell’s “powerhouse”. This boosts the production of ATP—cellular energy. More ATP means better performance and quicker recovery across tissues.

Collagen Production and Skin Rejuvenation

Red and near-infrared light help skin cells produce more collagen. This supports elasticity, reduces fine lines, and encourages a smoother, plumper appearance. Many use Red Light Therapy Beds and masks for this reason.

Reduction of Inflammation and Pain Relief

Photobiomodulation lowers inflammation by influencing oxidative stress and cytokine activity. This provides relief for conditions like arthritis, muscle soreness, and nerve pain.

Wound Healing and Tissue Repair

Red light improves blood flow and speeds up tissue repair. It’s useful for post-surgical healing, sports recovery, and chronic wounds. Even diabetic ulcers show improvement in some studies.

Hair Growth Stimulation

Devices using red light wavelengths can stimulate dormant hair follicles. Results vary, but many users report thicker, fuller hair over time—especially with consistent home use.


Different Forms of Red Light Therapy Devices

In-Office Treatments (e.g., Lasers, Professional Panels)

Clinics use high-powered lasers and large therapy panels for deep tissue treatments. These sessions are typically stronger and supervised by professionals, ideal for chronic issues or advanced skin therapy.

At-Home Devices (e.g., Masks, Handheld Devices, Panels)

Red Light Therapy at Home has exploded in popularity. You’ll find everything from face masks and handheld tools to full-body Red Light Therapy Panels. They’re safe, easy to use, and more affordable than ever.


Takeaways

  • Red light therapy wasn’t invented by one person, but evolved through discoveries from Newton to NASA.

  • Modern red light therapy combines lasers, LEDs, and biology, creating safe, effective treatments.

  • At-home options make it easier than ever to enjoy the benefits—no spa appointment needed.


Conclusion

From ancient sun worship to Nobel prizes and space-age breakthroughs, red light therapy has come a long way. Whether you’re after glowing skin, pain relief, or just curious about those Red Light Therapy Panels, now you know who started it all—and how it got here. Time to shine!
