Does the cooler weather having you feeling a little blue? It could be more than just a bad day. Seasonal Affective Disorder, or SAD, is a type of depression that comes and goes with the seasons, typically starting in late fall and easing up in early spring.

Amy Graham is a registered nurse and the director of the Senior Life Solutions department at Taylorville Memorial Hospital. She says the disorder is partially caused by the amount of light during the day.

Graham says there are multiple ways to cope with and reverse SAD.

Graham says friends and family should keep an eye on each other, as those dealing with SAD sometimes are the ones that don’t see the signs that they have it.
