Discussions regarding seasonal mental health transitions focus on the biological and psychological impacts of changing light levels. Early reports highlight Seasonal Affective Disorder (SAD), a clinical condition involving recurrent depressive patterns, fatigue, and appetite changes linked to disruptions in circadian rhythms, serotonin levels, and melatonin production. Subsequent observations expand on the phenomenon of ‘autumn anxiety,’ a non-clinical state characterized by irritability, low mood, and fatigue during the transition from summer to autumn. Recent scientific insights emphasize that as the sun sets earlier, the brain receives signals to increase melatonin production, which can lead to increased sleepiness and reduced productivity. Reduced sunlight can also lead to lower serotonin levels, which is linked to mood regulation. Neuroscientist Dr. Alison Breger notes a ‘physiological impulse to sleep longer in winter’ due to shorter days and the metabolic energy required to maintain body heat. Psychiatrist Dr. Veselin Gerev explains that reduced sunlight can lead to lower serotonin levels, potentially causing melancholy or SAD. As the transition into September and October progresses, the reduction in daylight hours—such as in Skopje, where daylight decreases from over 13 hours to less than 12 by month's end—disrupts internal biological clocks. In regions far from the equator, these oscillations may be more pronounced. In Argentina, weather patterns such as persistent cloudy days and heavy rainfall driven by El Niño have also been linked to lethargy and irritability. Beyond SAD, experts identify ‘autumnal asthenia,’ a condition involving muscle fatigue, sleep difficulties, apathy, and lack of concentration. To mitigate these effects, specialists recommend 20 to 30 minutes Psychologist Jorge Lareo Otero explains that the arrival of morning or early afternoon natural light, maintaining consistent sleep schedules, autumn and engaging in moderate seasonal time changes can exacerbate pre-existing anxious-depressive symptoms, leading to increased psychological consultations. Symptoms of autumnal asthenia include physical activity. While supplements like Vitamin D or magnesium are discussed, experts advise consulting a physician, noting they cannot replace light fatigue, muscle weakness, emotional apathy, and sleep. cognitive challenges that can impact social, family, and professional life.
