Isn't that the reason why the change happens on Sundays so that you can sleep in and get accustomed to it. People travel a lot now-a-days across multiple timezo

  As a former frequent business traveler, I can tell you it is amazing what even one timezone will do to you with regards to sleep. I reside in the CST, and traveling to the west coast would take me a few days to acclimate, and then I would fly back home to only fly to the east coast the next week. Don't underestimate the impact of how a single hour of time can impact the brain. Two timezone differences to the human body can be huge.

  If you have the luxury of being able to sleep well regularly then an hour here or there can be accommodated for without terrible disruption. However, a lot of people work more than 40 hours a week, and have significant commute times as well. Typically what ends up suffering is sleep. When people are chronically sleep deprived shifting an hour earlier can have a huge impact (e.g. going from 6 hours of sleep to 5, or even 5 to 4). Also, sleeping in on Sundays doesn't help. By definition if you don't use the new time to control when you wake up on Sunday morning then your sleep schedule will not be adapted to the new schedule at all. All that will be different is you will have a stronger incentive to go to bed an hour earlier due to the time on the clock, though your body will still be set to fall asleep and wake up an hour later.
