The data is in: The springtime change to DST is the event that is the most disruptive to our sleep in 2019. The methodology that we used to make this determination is by analyzing bedtimes for the days following the time change. Our wake times tend to be fixed due to kid schedules, work schedules, and other obligations. Yet we have some latitude with our bedtime. The later we got to bed, the shorter our sleep opportunity. The data shows that it takes about two weeks in the Spring to get back to balance. That’s very disruptive.
P.S. Personally I hope that this year we stay on DST and do not revert in the fall.
