alarmclockWhen you turn your clocks forward and “lose” an hour on March 14 to observe Daylight Saving Time, you may find yourself running behind. But, that’s not the only day you could be running late. You may also want to keep your eye on the clock around 8 am during the first two weeks of your menstrual cycle and around 8 pm during the third week of your cycle. The reason? Fluctuating hormones make your internal clock run slower at those hours, so you feel like you have more time than you really do, according to a study in the journal Neuroscience Research.
