Embracing Summertime Mood Challenges: Reverse SAD Explained

In this episode of PA Mindset Matters Mini Mindset, hosts Jessica Spissinger and Mercedes Dodge review the third and final seasonal onset mood disorder discussing “reverse seasonal affective disorder,” or summer-onset depression. They note it’s less common than winter-onset SAD (about 0.5–2.5% vs. 5–10%) and can be missed because summer is assumed to be a season which most people enjoy. However, for those who struggle with summer depression, it may present atypically with agitation, irritability, restlessness, insomnia, appetite loss, and weight loss, sometimes resembling anxiety or manic irritability, and is linked to prolonged daylight, humidity, heat, and circadian disruption (including spring time change). They emphasize planning ahead, screening for seasonal patterns over at least two years, and prioritizing environmental management (dimming evening light, reducing screens, blue-light blockers, blackout curtains, temperature control, avoiding the “indoor trap,” and timing outdoor activity). We review psychotropic, lifestyle and treatment planning approaches.
