Circadian misalignment shiftwork study

Take part in a clinical trial investigating how the enhancement of Slow Wave Sleep (SWS) improves next-day cognitive performance.

Sleep difficulties are prominent throughout society and increase in prevalence as people undertake shift work. A reduction in the duration and depth of SWS in shift workers who may be sleep-deprived is likely to affect their next day cognitive performance. Due to the prevalence of sleep difficulties in shift workers and the number of individuals in the future that will undertake shiftwork, ways to improve sleep and promote cognitive function are of high importance.

The purpose of this study is to look at the effects of auditory stimulation on SWS quality transmitted through a device during sleep. Qualifying participants will be tested on their overnight cognitive performance during simulated night shifts over two weekends, a week apart in our Sleep Lab. You will be reimbursed for your participation in the study.

This study will take place at the Woolcock Institute of Medical Research, and has received approval from the Monash University Human Research Ethics Committee (Protocol No. 2017-8329). 


You may be eligible to participate in this study if you:

  • Between 30-50 years of age
  • Without chronic or neurological illnesses
  • Have a regular sleep wake cycle 
  • No sleep disorders
  • Normal hearing
  • Be able to stay inside a sleep lab for extended periods
