I sure do.  (Daylight saving is setting the clocks back an hour to give extra sunlight at the end of the day.)  It messes with my bodyclock and interferes with my usual routines – especially the heat being later interfering with when I eat my evening meal.  When its hotter later, then I eat later.  And this can lead to me not being ready to go to bed at the normal time.

You would think we would adjust to only an hours difference fairly quickly, but we don’t.  This is enough to gladden the hearts of daylight-saving-haters everywhere.

Surprisingly, for such a big change, there has been little research done on the impact of daylight saving.

 However there has now been a study done in Europe.  Till Roenneberg of Ludwig-Maximilian-University in Munich, and others, have studied how and whether people adjust to daylight saving.

Their research involved a large survey of 55,000 people and a study more intensive study of the sleep patterns of 50 people during the time around the beginning and ending of daylight saving.

The bottom line: we don’t adjust to daylight saving.

“after taking the seasonal adjustment into account, our results show that the human circadian clock does not adjust to the DST transition,” says Roenneberg.

This post is really a bit of self-indulgence.  It was just so gratifying to have my experience confirmed by this research.  I’ll try to get back to my usual style of providing information that can be immediately useful to you in my next posts.
