CLEVELAND - A sleep expert in Cleveland says bright light and exercise can help avoid sluggishness with the end to daylight saving time on Sunday.

Michael Decker is an associate professor of nursing at Case Western Reserve University and studies sleep disorders. He compares the sluggish feeling of turning the clocks back and the days getting shorter to jet lag.

Decker suggests getting a morning dose of sunshine and using blue-light emitting bulbs where we spend daytime hours. He also says daily exercise can help avoid darkness-induced doldrums in the winter.

Daylight saving time ends Sunday at 2 a.m. The clocks go back one hour. Daylight saving time returns at 2 a.m. local time March 9.
