Seasonal Affective Disorder is a subtype of major depressive disorder that follows a predictable seasonal pattern — typically beginning in autumn, deepening through winter, and lifting in spring. It is caused by a combination of disrupted circadian rhythm, serotonin dysregulation, and melatonin overproduction triggered by reduced daylight hours.
SAD is significantly more than the “winter blues.” It involves full depressive episodes that meaningfully interfere with work, relationships, energy, and quality of life. Research estimates SAD affects approximately 5% of the population, with a further 10 to 20% experiencing subsyndromal seasonal depression — real and significant, even if below the clinical threshold.
Although Florida's seasonal light variation is less extreme than northern states, seasonal depression occurs regularly across the state — particularly in individuals with biological sensitivity to light changes or a history of depression. At Serene Minds, all sessions are conducted via secure, HIPAA-compliant online video — available statewide from the comfort of your home.
“Seasonal depression is not about dreading cold weather. It is a biological shift that therapy can help you understand, manage, and move through — rather than simply survive.”
