Seasonal Depression Affects Older Adults

As the days get shorter and the evenings/nights get longer some of us may suffer from the "winter blues", also known as Seasonal affective disorder (SAD).

SAD is a type of depression that usually affects people during the winter months. It's more likely to affect people whose time spent outdoors is limited by severe weather, reduced mobility, or illness. With decreased exposure to sunlight a person's natural "body clock" rhythm can change and less sun exposure during shorter winter days can cause changes in brain chemistry – like serotonin and melatonin levels.

Serotonin is known as the happy chemical as it regulates mood, while melatonin is a hormone that plays a role in our sleep habits. When there are changes to these chemicals and hormones, it can cause symptoms of depression.

Risk factors of SAD:

• SAD is more common in women than men

• People with a family history or personal experience with depression

• Low blood levels of vitamin D

• Living far from the equator where there's less sunlight increases the risk of SAD. 

Symptoms of SAD can include:

• Lack of energy

• Feeling sluggish

• Loss of interest in activities

• Irritability and agitation

• Increased need for sleep and/or problems with sleep
