I hadn’t really thought deeply about the impact that light has on me until I had this chat with Dr Shelley James. The type of light I’m exposed to (natural or artificial) and the duration of that exposure has an impact on everything from my cognitive function, mood, memory, emotional state and mindset to my physical health, nervous system, brain chemistry, productivity, creativity and the outcomes that I produce on Planet me. Shelley suffered a Traumatic Brain Injury and one of the consequences was that she spent years in darkness and quiet due to her extreme sensitivity to light, noise and various other stimuli. She is an international expert on light and well-being, TedX and keynote speaker, WELL Advisor and Visiting Lecturer at the Royal College of Art. She is also a trained glass artist and electrician. Light is as important to the healthy function of every cell in our bodies as food, water and air and Shelley is on a mission to inspire others to harness the power of light to be healthier, happier and save the planet too.
