ST. CLOUD -- It's the time of year when the sun goes down earlier and darkness sets in by dinnertime.

That change from Daylight Saving Time to Central Standard Time can trigger sadness and depression in some people. It's called Seasonal Affective Disorder, also known as SAD.

Scott Palmer is the Director of CentraCare Health's Behavioral Clinic. He says symptoms include lethargy, sadness, depression and moodiness.

If you think you might suffer from SAD, you should talk to your doctor. He says there are some ways to treat SAD, including some home remedies like light therapy and exercise.
