Screen Time Before Bed Delays Sleep by Hours, Research Shows

A 2025 University of Queensland analysis found that adults who used phones or tablets in the final hour before bed took 23 minutes longer to fall asleep than those who avoided screens.

The timing matters because melatonin production peaks between 9pm and 11pm in most adults, and blue light from devices suppresses that hormone by up to 50 percent according to the same review. Toowoomba residents already report average sleep of just six hours and 40 minutes on weeknights, below the seven-hour threshold linked to higher daytime fatigue.

Evening routines near Ruthven Street

People living close to Ruthven Street can reach Laurel Bank Park gardens in under ten minutes for a screen-free stroll after dinner. Further east, the Picnic Point Escarpment walk offers a 1.8-kilometre loop with city lights visible but no need to carry a phone. Darling Downs Health runs a free six-week sleep workshop series at its Margaret Street clinic that starts again on 22 July and includes simple device curfew guidance.

Both parks stay open until 8pm during winter, giving families a practical alternative to scrolling on the couch. The spring flower festival community group has added a monthly twilight walk on the first Friday at Laurel Bank, starting at 6:30pm, where participants leave devices in a basket at the gate.

Practical steps that fit local schedules

Turning off screens at 8:30pm and switching to paper books or radio reduces the delay to under five minutes, the University of Queensland data showed. Charging phones outside the bedroom costs nothing yet lifts total sleep time by roughly 35 minutes a night in the study group. Locals can test the change for one week and track results with the free sleep diary template available at Darling Downs Health reception.

Next month the same clinic will host a drop-in session on 14 August from 5pm to 6:30pm focused on household routines that protect sleep without extra spending.
