Discovery and History of LED Red Light Therapy: 1960s ~ 2020s

Discovery and History of LED Red Light Therapy

LED therapy, or light-emitting diode therapy, is a form of phototherapy that uses specific wavelengths of light to stimulate cellular activity and promote various therapeutic effects. As LED red light therapy, uses 600nm- 900nm wavelength, it has a history that dates back several decades. Here’s a brief overview of the history of red light therapy:

Discovery of Photobiomodulation Effects (1960s)

The use of light for therapeutic purposes began with the discovery of photobiomodulation effects in the 1960s. Endre Mester, a Hungarian researcher, accidentally discovered that low-level laser light had a stimulating effect on hair growth in mice. This marked the beginning of research into the potential therapeutic applications of ELD light.

Early Experiments and Research (1970s-1980s)

In the following decades, researchers conducted various experiments to explore the effects of low-level laser light on biological tissues. They discovered that certain wavelengths of light, particularly in the red and near-infrared spectrum (630nm, 660nm, 670nm, 810nm, 830nm, 850nm), had positive effects on cellular function and tissue repair.

NASA’s Involvement (1990s)

NASA became interested in the potential benefits of LED light therapy for astronauts. In the 1990s, NASA conducted studies to investigate the use of red light for accelerating wound healing and tissue repair in space. These studies further supported the therapeutic potential of red light.

Commercialization and Popularization (2000s)

As research continued to accumulate, the commercialization of red light therapy devices began to gain momentum. manufacturers and companies started developing and marketing LED infrared and red light therapy devices for home use, and red light therapy became more accessible to the general public.

Widespread Adoption (2010s-2020s)

In recent years, red light therapy has gained popularity in various fields, including sports medicine, dermatology, fitness, and wellness. Athletes use it for muscle recovery, dermatologists incorporate it into skincare treatments, and individuals seek it for its potential benefits in areas such as pain management, inflammation reduction, and improved circulation.

Ongoing Research (2020s-future)

Research into red light therapy continues, with scientists exploring its potential applications in areas such as ophthalmology, neurology, gynecology, dentistry, oncology, and metabolic disorders. The field is dynamic, and ongoing studies aim to further understand the mechanisms underlying the therapeutic effects of red light.


Today, red light therapy is used in various settings, including clinics, spas, and homes, with red light therapy devices ranging from handheld units to larger panels. While more research is needed to fully understand its mechanisms and optimize its applications, red light therapy has become a widely recognized and utilized form of non-invasive, low-risk therapy for a range of health and wellness purposes.
