• Losing One Hour of Sleep Could Affect Mood, Focus and Health
Ontario residents will move their clocks forward by one hour on Sunday, March 8, 2026, marking the start of daylight saving time and the annual “spring forward” time change.
The shift means clocks will jump from 2 a.m. to 3 a.m., resulting in the loss of one hour of sleep for most people across the province.
Health experts say that even a small change in sleep patterns can affect mood, focus and overall wellbeing, often producing what some describe as a “time change hangover” similar to mild jet lag.
Sleep Disruption and Health Risks
Dr. Mark Boulos says sleep deprivation can have significant health consequences, particularly for people who already struggle with sleep disorders.
According to experts, reduced sleep has been linked to increased risks of accidents, reduced concentration and possible impacts on heart health.
Maintaining healthy sleep habits — often referred to as “sleep hygiene” — can help reduce the impact of the time change. This includes avoiding electronics before bedtime, keeping a consistent sleep schedule and ensuring at least seven hours of sleep each night.
Children Often Affected More Than Adults
Sleep specialists say children can experience greater difficulty adjusting to the time change.
Alanna McGinn explains that longer daylight hours can make bedtime challenging for younger children, who may resist going to sleep while it is still bright outside.
Parents are encouraged to gradually adjust bedtime routines in the days leading up to the time change by shifting schedules 15 to 30 minutes earlier each day.
Creating a darker sleeping environment with blackout curtains or white noise machines may also help children fall asleep more easily.
Mental Health Impact
Sleep disruption can also affect mental health.
Psychotherapist Terrilee Kelford says the sudden shift in sleep schedules can disturb the body’s natural rhythm, which influences hormones linked to mood and stress.
Experts say people who experience anxiety or depression should pay particular attention to sleep routines during the transition.
Tips to Reduce Time Change Impact
Health professionals recommend several strategies to ease the adjustment:
- Get natural sunlight early in the morning
- Maintain consistent sleep and wake times
- Limit cellphone and screen use before bed
- Stay active and exercise regularly
- Maintain healthy eating and hydration habits
Not All Canadian Regions Change Clocks
While most of Canada observes daylight saving time, some areas do not follow the seasonal clock change.
Regions such as Yukon and most of Saskatchewan maintain the same time throughout the year, and a few communities in northern Ontario also do not observe daylight saving time.
Despite ongoing discussions about eliminating seasonal clock changes, Ontario will continue to follow the traditional daylight saving schedule for now.
