So, here is it, Monday.  How do you feel?  Did you drag yourself into work, feeling more tired than when you left on Friday?  It doesn’t make a lot of sense, does it?  After all, you had the weekend to relax and sleep in.  Well, new research out of the University of Texas Southwestern says that may be the problem right there.  Turns out that the concept of making up for lack of sleep, by sleeping in late on the weekends, is a myth.

While we may have sleep debts, catching up on our zzz’s on our days off disrupts our circadian cycle, the very thing that governs our internal body clock, triggering us when to wake up in the morning or go to bed at night.  So, if you want to feel refreshed on Mondays, better to pass up on the extra hours of sleep and stick close to your regular weekday wake and sleep times says the Globe & Mail. Either that, or find a way sneak off for a power nap.
