Research Facilities

Our lab have access to a state-of-the-art, purpose-built, five-bedroom en suite facility for polysomnography and circadian assessment. We also equipped with various technologies and computer programmes to facilitate sleep research and assessments.

Polysomnography (PSG)

Polysomnography (PSG) is the gold standard of sleep assessment for research and diagnostic purpose. It involves the recording of multiple physiological variables during sleep, including brain activities, heart rate, breathing, eye movements, and muscle movements.

PSG can provide real-time information about what the person’s brain and body are doing while sleeping. It is the most accurate way to identify different sleep stages.

Our lab is equipped with four PSG system that can be run concurrently each night. Click on the video and learn more about the process of conducting PSG.

An actiwatch with a 14 days actigraphy

Actigraphy is a non-invasive, commonly used assessment tool in sleep research designed to examine the sleep-wake pattern and activity level during the day. Actigraphy can provide important information to facilitate the diagnosis of circadian rhythm related disorders. The user will typically wear this watch-like device on the wrist of their non-dominant hand over a couple of days while going about a normal routine.

This graph on the left shows a person’s sleep-wake pattern over several days as measured by actigraphy where the blue area indicates inactivity (aka sleeping) while the black lines represent activities level. If you are curious about your sleeping habit, join one of our many studies and have a try!

Re-Timer Light Therapy Glasses

Re-Timer is a portable light therapy glasses designed to improve your sleep by delivering light therapy. The device works by delivering bright light into your eyes and help you to adjust your body clock by moving it to earlier or later, depending the time of the day you use the device. This form of treatment is effective for treating circadian rhythm related disorders and mood disorders.

We are currently using the Re-Timer glasses in our cognitive behavioural therapy and bright light therapy for insomnia with delay sleep phase clinical trial. If you are interested in the study, please sign up or reach out to us.

Cognitive & Visuomotor Tasks

We utilise a wide range of cognitive and visuomotor tasks to study the effects of sleep loss and sleep disruption on human performance.
