World’s first smart sleep tech wearable using blue-green light

Light therapy with retimer involves exposure to blue-green light for a prescribed amount of time at a specific time of day. The wave length of the light used has been found to be most effective in changing our ‘body clock’, or circadian rhythm.

Prof. Leon Lack

Professor Leon Lack is a Research Professor of Psychology at Flinders University. He is also a Clinical Psychologist who treats insomnia and circadian rhythm disorders at the Adelaide Institute for Sleep Health (AISH). Leon earned his PhD from The University of Adelaide and received his Bachelor of Arts from Stanford University in the USA.

He is acknowledged internationally as one of the world’s leaders in circadian rhythms and the behavioural management of insomnia. He has published over 200 scientific articles, book chapters, and books since 1980. He has received many large research grants from the Australian Research Council and National Health and Medical Research Council. For the last 30 years he has also directed a clinic for the non-drug treatment of insomnia at AISH and has supervised many clinical Masters and PhD students in this area. He was a co-founder of the Australasian Sleep Association where he was president from 1989 to 1992.

Dr. Helen Wright

Helen is an avid researcher in the areas of sleep, circadian rhythms and insomnia. Her research at Flinders University pioneered the different wavelengths of light (colours) effects on the re-timing of the body clock. Consistent with other contemporary research from other labs, her work confirmed that blue and blue-green light were the most effective for re-timing the body clock. She is particularly interested in cognitive behaviour therapy for insomnia and bright light therapies for the treatment of insomnia experienced by adolescents and adults.

Helen is author on a number of peer-reviewed journal articles. She has also co-written a book for the general public describing how to improve sleep and daytime functioning.

Helen earned her PhD from Flinders University of South Australia, and also holds a Masters in Psychology (Clinical).
