Well, I still think it's more a case of your body adjusting to the new time.
And actually, time zone travel is relevant. If you go to the Equator, you'll
get 12 hours of daylight and 12 hours of darkness, whatever time of year you
Sunrise and sunset actually change by a lot more than an hour between winter
and summer. I think there's about 7 hours of difference in light between the
longest day and the shortest day. I doubt if you need to make adjustments
that reflect that change in its entirety, yet it is a massive one in terms of
daylight. I tend to adjust my basals to deal with different dawn syndrome
patterns between summer and winter, but not to the extent of 7 hours'
difference. So on the scale of things, a sinlge hour's difference isn't that
But who am I to say you don't need to change your basals to take Daylight
Saving into account? If you think you do, then far be it from me to stop you!
Hmm, do you think I can get funding for a research project to look at what
happens to my basal needs when I go to the Equator for 6 months and then
Antarctica for 6 months?
