Winter depression is usually diagnosed as seasonal affective disorder (SAD). It usually begins during the fall, according to the Mayo Clinic, and can continue throughout the winter season, making life harder than it needs to be. Overcoming winter depression may be as simple as taking a vitamin D supplement, although other treatment options are also available.
Signs and Symptoms
According to health website Family Doctor, signs and symptoms of SAD include "a change in appetite, weight gain, a drop in energy level, fatigue, a tendency to oversleep, difficulty concentrating, irritability and anxiety, increased sensitivity to social rejection, avoidance of social situations and a loss of interest in the activities you used to enjoy." Consider seeking treatment if you are experiencing sadness for days at a time or are unable to engage in daily activities, according to the Mayo Clinic.
Vitamin D
According to researchers at the Department of Medicine at Union Memorial Hospital in Baltimore, Maryland, SAD occurs when the body lacks stores of vitamin D. According to their study, published in the Journal of Nutrition, Health and Aging in 1999, most people affected by SAD showed significant increase in health after taking a vitamin D supplement. Based on these findings, taking vitamin D or eating more vitamin D-rich foods may relieve sufferers of SAD of their depressive symptoms.
Light Therapy
According to health website Family Doctor, light therapy can be helpful in combating SAD; specialized light boxes are available for purchase to help SAD sufferers. During a light therapy session, you will sit in front of a specialized light that affects the brain chemicals connected to mood; such light can help you feel more positive. The light is supposed to mimic outside, natural light. It is unknown exactly how this light therapy works or how it is effective, so talk to your medical specialist before attempting this type of therapy on your own.
Medications
If symptoms are severe, medical intervention may be necessary, according to the Mayo Clinic. Bupropion may be used to treat SAD, although other antidepressants may be prescribed. Generally, your health practitioner may suggest that you begin taking an antidepressant before the winter season begins in order to maintain a healthy attitude before any symptoms occur.
Psychotherapy
Your doctor may suggest psychotherapy or other behavioral therapies to help treat your symptoms of seasonal affective disorder. This type of behavioral therapy is similar to what psychiatrists often use to treat clinical depression. During treatment, you will learn techniques to help alter your thoughts and actions so they are more positive and uplifting.
