Oct. 21--Feeling a bit down around this time of year isn't uncommon -- in fact, many Americans experience mood drops as winter moves in.

Millions of people in this country suffer from some level of Seasonal Affective Disorder, often dubbed the "wintertime blues," with the effects often being worse in places with long winters like Minnesota.

To address the issue, Austin-based chiropractor Dr. Kelly Nesvold will give an informative presentation Thursday at Riverland Community College.

Nesvold said one main thing he stresses this time of year is taking Vitamin D supplements.

SAD is often triggered by decreased sunlight, and it is sunlight that largely produces Vitamin D in the body, Nesvold said.

That vitamin is often associated with bone health, but it is also essential in disease prevention, muscle performance and gum health, among other things.

"We often don't get enough Vitamin D from October to May," Nesvold said.

Nesvold said there are other important things a person can do to prevent seasonal depression.

The doctor said a healthy diet is important, as is exercise -- even in small amounts.

Nesvold said a quick, 10-minute walk during a lunch break can often give someone more energy for a few hours.

In addition to his focus on the wintertime blues, Nesvold's presentation will look at how people can improve their overall health.

He said his focus is always on simple things that can be easily adopted -- such as chiropractic adjustments to desk chairs and proper sleeping positions.

Nesvold's easy tips are all part of what he calls the "five facets of health" -- nutrition, exercise, good posture, positive mental attitude and spinal alignment.

And to make strides in those areas, the doctor says simplicity is best.

"Doing several simple things that are healthy for you can make a big difference," Nesvold said.
