UQ School of Health and Rehabilitation Sciences researcher Associate Professor Asad Khan spoke to Nine News about a UQ-led study linking frequent intake of soft drinks and junk food with sleep disturbance.
The study found frequently eating processed food and carbonated soft drinks can cause stress-related sleep disturbance.
Dr Khan said having soft drinks more than three times a day and fast food more than four days per week are significantly associated with sleep disturbance in all but low-income countries.
"If you are sleep deprived then you are likely to have that kind of hormone which is actually making you hungrier so you are going to have more food," he said.
