That being said, it can also play havoc on your internal clock, particularly if you're already sleep-deprived. Dr Charles Samuels is the VP Clinical for the Canadian Sleep Society and he tells CHSJ News there's data to support a greater frequency of accidents after time change.
Samuels says the Canadian Institute of Health Research actually recommends you get caffienated before you get behind the wheel as your body adjusts to the time change.
While he says the time change isn't something you need to worry too much about, you should actually be concerned with how much sleep you're getting in general. Samuels cautions that most adults are carrying around an accumulated sleep debt of as much as 7 hours, and could reap major benefit by simply laying down for a 15 minute nap at the end of the work day.
