It's that time of the year again, Sunday morning we will roll the clocks forward into daylight saving time.  It's a bittersweet deal that simultaneously signals spring and wreaks havoc on sleep.  For most people "springing forward" means a sleepy Monday.  But for some it takes a heavy toll on mood and productivity.

"Sleep is an absolutely necessary biologic time," explained Sleep Physician at Lehigh Valley Health Network, Dr. Joseph Schellenberg.  "It's a time of healing and restoration."

Schellenberg says changing the clocks is very similar to jet lag.

"Affects what's called your  circadian rhythm, and that is your body clock."

Your body clock is also known as the sleep-wake cycle, and when it doesn't match up with light-dark cycles people can feel out of sync, tired and grumpy.  Daylight saving time has even earned blame for car accidents and workplace injuries.

"Sleep deprivation can definitely affect performance," shared Schellenberg.

That sleep deprivation can affect heart health.  Studies show there's a spike of heart attacks the first few days after the time change.

"If you're not getting enough sleep your body will be in a slightly more stressed state and is not having enough time to repair itself," added Schellenberg.

If you want to be on your A-game this work week, health experts say there are some things you can do to minimize the effects of losing an hour.

"The big thing on this particular weekend, don't stay up later then you usually would on that Saturday night."

And he says avoid the urge to sleep in Sunday.  Getting up at regular time is best for your body.

"The sooner you can get yourself onto your normal sleep-wake cycle the more rapidly you'll adapt," advised Schellenberg.

The time change happens Sunday morning at 2AM, so don't forget to move your clocks ahead one hour.
