Screen time and sleep: what the research actually shows
Recent findings link evening device exposure to measurable drops in sleep quality for adults in coastal New South Wales.
How we reported this
Adults who scroll phones or tablets in the hour before bed lose an average of 48 minutes of restorative sleep each night, according to data compiled by the Sleep Health Foundation in its March 2026 national survey.
The timing matters because blue light from screens suppresses melatonin production, a hormone that signals the body to wind down. This effect shows up most clearly in people aged 25 to 44 who work from home or study online after dark. With more residents in the Illawarra region relying on screens for both work and entertainment, the pattern has become harder to ignore.
Local routines under pressure
Many Wollongong residents finish the day near Crown Street Mall before heading home along Harbour Street. Some then join evening classes at the Nan Tien Temple wellness centre on Berkeley Road, where screens are banned after 8 pm to encourage better rest. Others cycle the coastal path through Stuart Park and return to lit-up living rooms, extending their device time well past sunset. These habits cut into the seven to eight hours of sleep recommended by local GPs at the Wollongong Hospital sleep clinic.
Community programs at the Illawarra Sports and Recreation Centre on Gipps Street now include a monthly screen-free evening session aimed at shift workers. Participants report waking less often during the night when they leave devices in another room.
Evidence from the numbers
A 2025 University of Wollongong study tracked 312 adults across the Illawarra for four weeks and found that those who reduced screen time after 9 pm gained 34 minutes of total sleep on average. The research used wrist-worn trackers and logged device use through phone settings. Participants who paid the $45 fee for the six-week follow-up workshop kept the gains three months later.
Small changes produce results. Setting phones to night mode by 8:30 pm, charging devices outside the bedroom, and replacing late scrolling with a short walk along the rock pools at North Wollongong all help restore natural sleep cycles. Residents concerned about ongoing sleep issues should speak with a local medical professional for personalised guidance.
