Daylight Saving Time and Your Health

Most of Canada shifts between standard and daylight saving time (DST) each year in an effort to “save” natural light. Clocks will get set one hour back on Sunday, Nov. 6, 2022 when the DST period ends. Although you may be excited about gaining another hour in your day, DST can wreak havoc on your physical and cognitive health for several days, weeks or even months.

The disruption of DST can negatively impact your health. Your internal clock regulates critical processes, including liver function and the immune system. Interruptions to the circadian rhythm, your body’s 24-hour biological cycle that regulates wake and sleep, can also impair your focus and judgment.

While you may be tempted to use the extra hour to indulge in various activities, health experts recommend using that time for sleep. To help make the DST transition easier, consider going to bed 15-20 minutes early in the days beforehand to help your body get used to the difference. If you have specific health concerns, talk to your health care provider.
