Seasonal changes and the phenomenon of autumn anxiety

The transition from summer to autumn can trigger a phenomenon often referred to as ‘autumn anxiety,’ characterized by increased anxiety, low mood, irritability, fatigue, and loss of interest in daily activities. While not a formal medical diagnosis, experts note that these feelings often recur annually during this season.

Medical professionals suggest that reduced exposure to sunlight plays a significant role. Lower light levels can lead to decreased serotonin—a hormone affecting mood, appetite, and sleep—and increased melatonin, which promotes drowsiness. Additionally, a decrease in vitamin D levels due to less sun exposure is linked to depressive symptoms.

Psychologists distinguish this experience from Seasonal Affective Disorder (SAD), which is clinically classified as major depressive disorder with a seasonal pattern. Other contributing factors include changes in routine, such as returning to school or work, and shifts in sleep patterns. To mitigate these effects, experts recommend maximizing daylight exposure, engaging in regular physical activity, and seeking professional help, such as cognitive behavioral therapy, if symptoms interfere with daily life.
