A weekend lie-in may be more beneficial than we realise. Dr Liu and researchers from the University of Sydney have found that insulin sensitivity can be improved by catching up on sleep at the end of a busy week, and retaining the body’s sensitivity to insulin reduces the risk of developing Type 2 diabetes – a chronic illness that is a major cause of death.
In the study, men slept an average 6.2 hours of sleep each work night, but then regularly caught up on their sleep at the weekends, sleeping an average extra 2.3 hours per night. Dr Liu said: “The good news is that by extending the hours they sleep, adult men – who over a long period of time do not get enough sleep during the working week – can still improve their insulin sensitivity”.
