Seven Resources on Treating Seasonal Affective Disorder with Integrative Medicine

Help Patients Cope with Seasonal Affective Disorder and Stress

Symptoms associated with SAD include depression, anxiety, mood changes, sleep problems, lethargy, and overeating. But what causes these things to occur? The reduced level of sunlight in the fall and winter months may affect an individual’s serotonin, a neurotransmitter that affects mood, according to a 2010 report by Dr. Darren Cottrell, a Locum Consultant at St. James Hospital in Portsmouth, England. Lower levels of serotonin have been shown to be linked to depression. Brain scans have shown that people who had seasonal depression in the winter had higher levels of a serotonin transporter protein that removed serotonin than in individuals who did not have seasonal depression, the report says.

In addition, melatonin, a sleep-related hormone secreted by the pineal gland in the brain, has been linked to seasonal depression, says a 2013 report by Stuart L. Kurlansik and Annamarie D. Lbay in the Indian Journal of Clinical Practice. This hormone, which can affect sleep patterns and mood, is produced at increased levels in the dark. Therefore, when the days are shorter and darker the production of this hormone increases. Melatonin can also affect an individual's circadian rhythm, or "biological clock", resulting in ‘internal clocks’ being out of sync with ‘external clocks’, or the usual sleep and wake rhythms. This can result in some of the symptoms associated with seasonal depression.

To treat seasonal depression, take a holistic approach to helping patients work through mental health issues, according to a recent release by the Tao Institute of Modern Wellness. Phototherapy or bright light therapy has been shown to suppress the brain’s secretion of melatonin. Light therapy has been shown to be effective in up to 85 percent of diagnosed cases. Patients remain in light up to ten times the intensity of normal domestic lighting up to four hours a day, but may carry on normal activities such as eating or reading while undergoing treatment.  The device most often used today is a bank of white fluorescent lights on a metal reflector and shield with a plastic screen. Cognitive behavioral therapy (CBT) has also been shown to be effective.
