If you forgot to change your clock before you went to bed for Daylight Saving Time you may have missed an appointment or deadline.

The annual tradition of losing an hour's sleep in the spring has historically been seen as a money-saving measure, cutting back on electricity, but these days the time-shift seems to cost us in health.

Studies show there is an increase in accidents and work related injuries the week after the time change. Researchers also say the setback in slumber can slow productivity at work.

There is good news though. The extra hour means more sunshine. After feeling like hibernating all winter, Seasonal Affective Disorder often fades this time of year.
