PHILADELPHIA (CBS) — We are now on Standard Time which means we got an extra hour of sleep Saturday night. However, for those with insomnia, it can be especially difficult to adjust to the time change.

If you’re one of the millions of people who have trouble sleeping, then that extra hour of sleep today is more of a curse than a blessing.

“For some people that really would mean for their bodies that they are sleeping in one hour later than they normally do and that delay in that one hour may for some people cause a dysregulation,” says Dr. Karl Doghramhi, Director of the Sleep Disorders Center at Thomas Jefferson University Hospital.

Doghramji says it’s critical for those with insomnia to keep their normal bed time and wake up time regardless of the clock change.

“Some people need to be very, very exact in the time that they wake up to keep that system going on a regular basis.”

It helps to get exposure to sunlight in the morning and avoid taking long naps. Also, don’t eat three to four hours before bedtime and limit your caffeine and alcohol.
