Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Hour time and your time: Take a moment to plan for the change to Daylight Saving Time

Ontario Tech sleep researcher offers strategies to help adjust to the one hour time change on the second Sunday of March


As sure as the arrival of spring each March, comes the weekend where we change our clocks to move forward one hour to Daylight Saving Time.

For about a century, most Canadian communities have been adjusting clocks in the spring to take greater advantage of longer daylight hours afforded to the northern hemisphere in the warmer summer months.

But with the time change comes a brief physiological adjustment, says Ontario Tech University sleep researcher Dr. Efrosini Papaconstantinou of the Faculty of Health Sciences.

“Although the time change happens in the middle of a weekend to minimize impact (Sunday, March 13 this year), many people find that the following day, on Monday, might feel a bit out of step,” says Dr. Papaconstantinou. “In fact, it can take several days for the body to catch up with the time shift. The ‘lost hour’ generally comes at the expense of valuable REM (rapid eye movement) sleep, which is part of the second-half of the overnight cycle where the brain consolidates our memories and what we learned during the previous day.”

Sleep, of course, regulates mood and cognitive function.

“The consequence of losing that hour of sleep is decreased reaction time the next day, which makes us more prone to accidents. Any loss of sleep, particularly for anyone who may be feeling sleep-deprived going into the time-change weekend, can leave people feeling ‘extra’ groggy.”

Young children often have a more difficult time with the change, whereas adults can turn to options like having an extra cup of coffee on the Monday.

Strategies for navigating the time change

Our brains like to take cues from our surroundings and really like regularity. To reduce the impact of Daylight Saving Time, adjust your bedtime and wake time gradually in 15-minute increments over several days. Once you’re in Daylight Saving Time, make sure to keep a consistent schedule.

Some other basic sleep hygiene tips include:

  • Avoid alcohol and/or caffeine within four hours of bedtime in the coming days.
  • Keep your communications devices turned off to avoid the light from smartphones and computers.
  • A dark room with relatively cool temperature can also be extremely helpful in transitioning to an effective night of rejuvenating sleep.
