Evening Screen Time Cuts Sleep Duration for Central Residents, Study Shows

Central Health Department records from the first half of 2026 show that adults logging more than three hours of screen time after 8 p.m. averaged 47 fewer minutes of sleep per night than those who switched off earlier.

The pattern surfaces at a time when many locals already juggle work emails and streaming on the same devices well into the evening. Public health staff note the timing coincides with longer daylight hours and the launch of new after-hours fitness classes that keep people indoors and online later than in prior years.

Programs on the ground

The Riverside Wellness Center on Oak Street runs a six-week pilot that supplies participants with blue-light blocking glasses and tracks their sleep via wearable devices. A second effort, the Central Active Living initiative based at the Maple Park recreation building on 12th Avenue, added evening device-free zones starting June 1. Both sites report steady sign-ups from residents in the nearby Riverfront and Hilltop neighborhoods.

A March 2025 study in the Journal of Sleep Research tracked 1,200 adults across similar mid-sized cities and found each additional hour of pre-bed screen exposure raised the odds of reporting poor sleep by 19 percent. Central Health Department staff applied the same methodology to local survey responses collected in April and recorded nearly identical results. The department spent $18,400 on the local data collection, covering recruitment at three community sites and analysis by two statisticians.

Residents who want to test the findings themselves can start by setting a device curfew at 9 p.m. and joining one of the free workshops the Riverside Wellness Center schedules for July 14 and July 21. Staff there recommend checking in with a primary care provider before making larger changes to routines.
