Evening Device Use Delays Sleep by Hours, Manchester Study Finds
New findings detail how evening device use delays sleep onset for Manchester residents by measurable margins.
How we reported this
University of Manchester researchers tracking 1,200 adults found that participants who used phones or tablets in the hour before bed took an average 42 minutes longer to fall asleep than those who avoided screens.
The timing matters because Greater Manchester has seen device ownership climb steadily since 2022, with many residents now juggling work notifications into the evening across neighbourhoods from the Northern Quarter to Chorlton. Public health teams note rising reports of fatigue-related absences at local employers, pushing sleep into the foreground of routine wellness checks rather than a fringe concern.
Manchester programmes target evening habits
The University of Manchester’s Sleep and Circadian Neuroscience Institute on Oxford Road runs free weekly workshops that test blue-light filters and device curfews with participants. Down the road at Manchester Central Library on St Peter’s Square, a six-week pilot launched in May 2026 offers residents loaned light-blocking glasses and logs their sleep via simple apps for four weeks at no cost. Both efforts focus on measurable changes rather than blanket bans on phones.
Key numbers from the latest data
A 2025 Greater Manchester Health and Social Care Partnership survey of 4,500 residents recorded that 37 percent kept a phone within arm’s reach overnight, correlating with a 19 percent rise in self-reported insomnia symptoms compared with the 2023 baseline. The same report placed average evening screen exposure at 78 minutes for adults aged 25 to 44. Workshop attendees at the university site who reduced that window by half improved their sleep efficiency scores by 11 percent within 10 days, according to internal logs shared with participants.
Residents can start tonight by setting a device curfew at 10pm and switching to paper books or dimmed lamps in the bedroom. The library pilot accepts new sign-ups through its website until the end of July, while the university institute lists open sessions on its public calendar each Tuesday evening.
