Seasonal Affective Disorder and emotional shifts during seasonal transitions

As seasons change, psychological and emotional shifts are often observed. Seasonal Affective Disorder (SAD) is a clinically recognized condition characterized by recurrent seasonal patterns of depression, typically manifesting in autumn and winter due to reduced sunlight exposure.

Biological mechanisms linked to SAD include disruptions to the circadian rhythm, decreased serotonin levels which affect mood, and increased melatonin production leading to excessive sleepiness. Common symptoms include fatigue, apathy, changes in appetite—specifically cravings for carbohydrates—and weight gain. Vitamin D deficiency may also exacerbate these symptoms.

On an individual emotional level, the transition from summer involves different processing styles based on birth months. For instance, those born in April may face self-doubt, while those born in July may require more time for emotional healing. August births are encouraged to view rest and joy as significant rather than focusing solely on productivity.
