Studies suggest that this disconnect between body time and clock time can result in restlessness, sleep disruption and shorter sleep duration. Other studies have suggested links between time change and increases in heart attacks, suicides and accidents, though scientists say more study is needed.

I've never understood why a) we needed to shift time (as if people didn't understand that the day ebbs and flows as far as sunlight) and b) why one time couldn't be used for the entire globe (UTC?). Seriously, if they said a soccer match was going to start at 1600, why can't 1600 be the same worldwide?
