The circadian rhythm controls many aspects of our lives, hormone release, hunger, and sleep. Before the invention of the light globe, this important mechanism was set and reset it by the rise and fall of the sun.

My guest today, professor Sean Cain, Associate Professor of Psychology at Monash University, suggests humans may be even more sensitive to light than we already acknowledge.

His laboratory work focuses on individual sensitivities to light and how these insights may help us understand the influences of poor human health, including sleep disorders, metabolic diseases, and depression. He's the current president of the Australasian Chronobiology Society. So Sean, what is chronobiology and how does it fit in with your career right now?.

Marnie Ogg is talking to some of the brightest minds in their field, about the topic of light pollution and ways to protect our night skies.
