2. The Origins of Red Light Therapy
The history of light therapy dates back to ancient civilisations that recognised the healing properties of sunlight. Ancient Egyptians, for instance, utilised sunlight to treat skin diseases, while Greeks and Romans built sun temples for therapeutic purposes. However, the modern scientific approach to light therapy began in the early 20th century.
A pivotal moment in the history of red light therapy occurred in the 1960s, when Hungarian physician Dr. Endre Mester conducted experiments demonstrating the effects of low-level laser light on healing. His groundbreaking research showed that exposure to laser light significantly accelerated wound healing and hair growth, marking the beginning of a new era in light therapy.
Mester’s work laid the foundation for extensive research into the therapeutic applications of light, ultimately leading to the development of LED technology. Unlike lasers, LEDs offer a broader spectrum of light and are more versatile and accessible. Today, red light therapy is widely used in various clinical settings, aesthetic practices, and home care devices, with ongoing research expanding its potential applications in health and wellness.
3. Understanding LED Red Light Therapy
LED (Light Emitting Diode) red light therapy utilises specific wavelengths of light to stimulate biological processes within the body. Unlike traditional lasers, which produce concentrated beams of light, LED therapy emits a broader spectrum, allowing for more uniform treatment across larger areas of skin.
Key Mechanisms of Action
The therapeutic effects of red light therapy can be attributed to several key mechanisms:
