For the last 50+ years, we’ve been changing our clocks twice a year. While this was originally supposed to save energy, the disruption to our circadian rhythms has led people in countries engaged in this practice to wonder if it is still worth it anymore. While the vast majority of people feel we should “lock our clocks”, deciding on what permanent time to stick with is less clear. Are the choices arbitrary, or are there compelling reasons for one option over the other?

Speaker: Dr. Mike Antle

Dr. Michael Antle is a neuroscientist, Professor, and the Department Head of Psychology at the University of Calgary. He earned his PhD at Simon Fraser University in 2001. For the last 22 years, he and his research team in Calgary have been examining the inner workings of our brain’s circadian clock. This clock regulates all the daily rhythms of our body, including our sleep-wake cycle. Dr. Antle frequently applies his expertise in circadian rhythms to the public conversation around the biannual clock changes.
