Less sunlight and cold temperatures are often the cause of the winter blues.

"You're more tired, you're just not feeling the energy you normally would, you maybe aren't as interested in social activities, kinda want to hibernate a little bit," Mankato Clinic Psychologist Dr. Darcie Jacobs said.

You can even crave more carbohydrates.

However, there's a difference between the winter blues and seasonal affective disorder, Jacobs said.

"It's honest to goodness major depression," she said. "Just seems to be really affected by the shortening days and lack of daylight."

There are a number of ways to beat the winter blues. The first is to take advantage of the sun when it's out.

"Finding things that you like to do, even if it's just taking the dog for a walk for 15 minutes, is going to be helpful to our mood," she said.

Making plans to socialize, exercising and eating healthy all help improve your mood too.

If you're noticing your functioning is really down, it could be a sign of seasonal affective disorder.

"That you are just not wanting to get out of bed, it's starting to affect your work productivity, your relationships, and you're starting to see the effects of that, then you really want to consult your doctor," Jacobs said.

If it is season affective, things like light therapy, medication, testing vitamin D levels can help.
