Even after an extra hour of sleep, changing your clocks for Daylight Saving Time can actually make you feel like you have jet lag.
Speaking to Shane Foxman on the CKNW Weekend show, Dr.Maureen Ceresney from the UBC Hospital Sleep Disorders Program says our internal clock plays a big role, and how we perceive light exposure and what time we usually wake up can affect us.
“For some of us, if we are a little more sensitive to the affects of the light, that clock shift happens. We go to bed later and we’re still waking up at that early time that we’re waking up yesterday. So, we’re running a little shorter on sleep.”
Dr. Ceresney also says the time change in the spring is actually harder because the internal clock runs on a schedule longer than 24 hours.
She says even losing as little as a half hour of sleep can affect us.
“Certainly there’s data to show that around the time change both this time of year and in the spring time that there’s actually more traffic accidents. Stuff like that happens more often because we are a little less with it”.
Further, everyone’s sleep pattern is different because people are genetically wired differently she says the averages can range from 6 to 10 hrs of sleep.
