Evening Device Use Disrupts Sleep Cycles, Research Reveals

Adults who scroll on phones or tablets in the hour before bed lose 42 minutes of total sleep time on average, according to a 2025 review from the Canadian Sleep Research Network that tracked 1,200 urban participants over six months.

The finding arrives as more Kensington Market households report irregular rest amid longer work-from-home schedules and rising evening screen habits. Local wellness groups have noted increased inquiries about sleep since spring, when several neighbourhood programs began logging participant sleep logs alongside device logs.

Programs on Augusta and Baldwin

The Augusta Community Hub runs a weekly evening session on Baldwin Street that pairs device curfews with breathing routines. Attendance reached 68 people last month, with slots filling through the end of July. A block away, the Kensington Market Wellness Collective on Nassau Street offers a four-week series that starts July 15 and charges $45 for residents who bring their own sleep trackers. Both sites sit within the core market grid bounded by Spadina and Bathurst.

Researchers at the network tracked melatonin levels in a subset of volunteers and recorded a 19 percent drop when screens stayed on past 10 p.m. The same group compared results with earlier 2023 data from the same cohort and found the gap widened by an additional 11 minutes during winter months when daylight hours shorten.

Practical steps that fit market routines

Residents can test a one-hour screen cutoff by placing chargers in a kitchen drawer rather than beside the bed. The Augusta hub provides free printed timers for anyone who attends its next drop-in on July 12. Those who want longer-term tracking can borrow a basic light meter from the wellness collective for a $10 deposit, then return it after two weeks with their notes. Early reports from the current cohort show average bedtime shifting earlier by 25 minutes within the first week of the change.
