Beginning with sun worship in prehistory and sunshine therapies in ancient Egypt, Greece and India, light has long been associated with the sublime, the divine and healing. Yet only recently have we begun to understand how different parts of the light spectrum, from infrared to ultraviolet, can affect our physical and psychological well-being. Covering the historic, scientific and spiritual aspects of light and its role in energy medicine, Anadi Martel explores the vibrational nature of light and the interaction between light, biology and consciousness. He demonstrates light's incredible effects on the physical, energetic and cognitive dimensions of life and examines several forms of light therapy, including chromotherapy (colour therapy), heliotherapy (sun therapy), actinotherapy (ultraviolet therapy) and thermotherapy (infrared therapy). He details how to use light therapy daily, get optimal benefits from sunlight and avoid the health risks of new artificial lighting such as compact fluorescents and LEDs. Combining his own 30 years of research with practical insight from the many phototherapy pioneers he's encountered, the author examines scientific studies on how specific wavelengths of light influence our cells and DNA, brain function, sleep patterns and emotional stability, speed the healing of wounds and are effective in the treatment of disease, including arthritis, stroke, Alzheimer's, Parkinson's and brain and nerve injuries. Exploring the spiritual aspects of light, the author explains why auras and halos have been used to represent sages and saints of all traditions, revealing the intimate link between light and consciousness. Investigating the many laser, monochrome, audiovisual and infrared machines designed to heal disease and treat emotional disorders, Martel, also, reveals promising medical applications for light that are currently in development, inviting the reader not only to appreciate the complexities of light but to maximise its therapeutic dimensions. · Shares scientific research on how different wavelengths of light influence our cells, brain function, sleep patterns and emotional stability · Examines several forms of light therapy, including chromotherapy, heliotherapy, actinotherapy and thermotherapy · Explains how to use light and colour therapy, maximise the benefits of sunlight and avoid the health risks of new light sources such as compact fluorescents and LEDs
