Screen time and sleep: what the research actually shows

A March 2026 report from the Sleep Health Foundation tracked 1,200 Australian adults and found those who used phones or tablets within 60 minutes of bedtime recorded 25 percent less deep sleep on average than those who switched off earlier.

Remote work patterns have lifted daily screen exposure across Geelong since 2024, with many residents finishing emails or streaming shows late into the evening in homes near the waterfront. This shift matters now because Barwon Health recorded a 12 percent rise in sleep-related GP visits between July 2025 and June 2026, coinciding with higher device use after sunset.

Locals already use the Barwon River walking trail for morning light exposure that helps reset circadian rhythms, while the Geelong Waterfront parkrun on Saturday mornings draws hundreds who report steadier sleep after consistent early activity. Barwon Health runs free sleep education sessions at its Belmont clinic on the second Tuesday of each month.

Key mechanisms from the data

The foundation study measured melatonin levels and found blue-light exposure after 9 pm suppressed the hormone for up to three hours in participants aged 35 to 55. A separate June 2025 Australian Bureau of Statistics survey showed 42 percent of regional Victorians checked social media in bed on weeknights, a habit linked to longer time falling asleep.

Researchers noted that even dim screens on the lowest brightness setting still delayed sleep onset by an average of 19 minutes when used for more than 30 minutes before lights out.

Next steps for Geelong residents

Barwon Health recommends setting a device curfew at 9 pm and replacing late scrolling with a 20-minute walk along the Eastern Beach rock pool path. Participants in the clinic program who followed this routine for four weeks reported falling asleep 14 minutes faster on average. Residents can book a session through the Barwon Health website or call the Belmont clinic on weekdays between 9 am and 4 pm.
