Reset your body clock – how light affects your mood everyday

Our bodies have an innate ability to tell the time – it evolved so that we were inclined to rest when it was safe, and were keener on travelling or hunting and gathering when food was plentiful. The sun and our body’s ability to perceive its light kept our internal clocks ticking along consistently.   But today, many of us spend most of our days indoors, and much of our nights in artificial light. We’ve confused our internal clocks, and that can wreak havoc on our bodies and minds.   Dr Jacob Crouse is on a mission to improve the lives of people living with depressive and bipolar disorders – and it turns out light may be one of the keys to fulfilling that mission. Jake explains why people affected by bipolar disorder tend to have more disrupted ‘circadian rhythms,’ and what his research reveals about everybody’s need for the right light at the right time.   +++  The Solutionists is podcast from the University of Sydney, produced by Deadset Studios.
