Have you or anyone you know experienced depression that coincided with the changing of seasons? Seasonal affective disorder (SAD), more commonly referred to as seasonal depression, or major depressive disorder with seasonal pattern, is depression that strikes predominantly in the fall to winter and lifts during the spring and summer when there is more natural sunlight.
Are you at risk?
SAD affects women at rates four times higher than men, with 20-30 years of age being the most common age of onset. Some risk factors include age (SAD is more common in young people), history of major depression and proximity to the poles. There is also a correlation between those diagnosed with SAD and a family history of psychiatric disorders, with 55 percent having a severe depressive disorder and 34 percent having used alcohol.
Some causes of SAD include an irregular circadian rhythm, and unbalanced serotonin and melatonin levels—two neurotransmitters responsible for mood and sleep patterns. Lack of sunlight seems to reduce serotonin production, increase formation of melatonin and throw the body’s internal clock off.
What are the signs?
Those with seasonal depression are likely to experience various signs and symptoms, some more obvious than others. Here are some behavioral changes to be aware of:
What should you do?
While there are a variety of treatment options available for people experiencing SAD, there are also some things you can do to practice self-care, or to support someone in your life who may be experiencing SAD. Early intervention is key in preventing and lessening symptoms of SAD and other forms of depression. If you are concerned about someone in your life, here are a few ways you can support them:
If you are experiencing symptoms of SAD, don’t be afraid to ask for help. When in doubt, turn to your community. Reach out for resources about dealing with depression. Websites, books, support groups, help lines and specialty organizations for depression and suicidal thoughts are good places to start.
As always, if you or someone you know are thinking about suicide or experiencing an emotional crisis, call the National Suicide Prevention Lifeline at 800-273-TALK (8255), or text the Crisis Text Line at 741741.
