Researchers testing how coronavirus pandemic has affected our sleep

Sleep experts concerned about the detrimental effects the pandemic is having on our sleep are investigating the use of light therapy.

The Woolcock Institute is researching the link between home lighting and sleep patterns among Australians who are spending more time indoors during COVID-19.

"I think they're staying at home longer, they're not getting as much natural sunlight than they did before and it's disrupting their sleep patterns," Associate Professor Christopher Gordon from Woolcock Institute of Medical Research said.

Dr Gordon is putting that link to the test by recruiting 80 people over the age of 50 across New South Wales.

Participants in the study wear watches to measure their sleep and a small sensor is used to monitor light exposure over one week.

"We know that light is really important in regulating the body clock," Dr Gordon said.

Stage two of the study will involve participants visiting the laboratory to receive specific doses of light with the aim of improving their sleep.

They will be exposed to blue-enriched light during the day and blue-depleted light in the evening.

"We know people with sleep disturbances are often prescribed sleep medication and that can work for a short period of time but it's not a long-term solution," Dr Gordon said.
