We all have those days when we realise that we should have gone to bed earlier the night before. The next day we might feel groggy, slow or short-tempered, but how much does this cost in terms of money? According to a new economics report a collective lack of sleep is costing the Australian economy over 66 Billion dollars. This figure takes into account the lost productivity at work and the related health and medical bills that come along with a lack of sleep.

Considering that we have probably been sleeping for 8 out of 24 hours in a day or over a 3rd of our lives Australians should be pretty good at this by now. To discuss the effects of sleep deprivation and to understand more about the sleeping patterns of Australians The Daily was joined by Dr. Siobhan Banks, Associate Professor at the Centre for Sleep Research at the University of South Australia.
