Eminent scientist Russell Foster, Professor of Circadian Neuroscience at Oxford University, shares some of his extraordinary life’s work, taking us on a fascinating journey through the science of our body clocks.

As work and recreation time has become increasingly blurred, we’ve neglected our 24-hour biological clock which guides us towards the best time to sleep, eat and think.

Using his own studies and those of other international sleep scientists, Russell explains how new science has proved that living out of synch with our clock not only disrupts sleep, but leaves us more vulnerable to infection, cancer, type 2 diabetes, heart disease and mental illness.

However, with the right knowledge, we can get back into our rhythm and live healthier, sharper lives.
