Biological and social impacts of seasonal transitions

Overview

Health experts continue to address the physiological and psychological challenges associated with seasonal transitions. As the season shifts toward autumn, the transition can trigger ‘autumn fatigue’ or seasonal asthenia, characterized by physical and mental exhaustion, decreased concentration, and mood changes. Reduced exposure to natural light disrupts circadian rhythms and melatonin production, while the shift from flexible summer routines to structured schedules further complicates adaptation.

Recent research highlights that the return to school and work routines can cause difficulty waking, low energy, and appetite changes. Doctor Valerijus Morozovas notes that the body may require several weeks to adjust to these new schedules as cortisol and melatonin secretion recalibrate. Furthermore, studies in the ‘Journal of Physiological Anthropology’ confirm that lower daylight levels affect sleep-wake cycles, while research in the ‘New England Journal of Medicine’ indicates a slight average weight increase of approximately 0.48 kilograms from early autumn to the new year.

Newer developments emphasize the gut-brain axis; research in ‘Nature Microbiology’ suggests decreased gut microbiota diversity can lower serotonin and increase cortisol, contributing to lethargy. Beyond biology, the transition can influence social dynamics, such as ‘cuffing season’—a phenomenon where individuals seek closer romantic connections for stability—and ‘cocooning’ rituals centered on home-based comfort. However, psychologists warn that the social media portrayal of autumn aesthetics can create undue stress.

As the transition progresses toward winter, experts highlight risks to respiratory health, noting that cold, dry air can exacerbate asthma. The upcoming winter time transition, scheduled for late October 2026, is expected to further disrupt circadian rhythms. Professor Alfredo Pontecorvi notes the body must resynchronize internal rhythms, which may cause fluctuations in cortisol and growth hormone. To manage these shifts, experts recommend morning light exposure, light therapy lamps, consistent sleep schedules, and strategic midday ‘power naps’ to restore mental clarity.

Claims

What the coverage asserts, and how many sources carry each claim.

[● 5 SOURCES] Reduced daylight affects the internal clock that regulates the sleep-wake cycle.
[● 5 SOURCES] The body secretes more melatonin, a hormone involved in sleep regulation, during the night.
[● 5 SOURCES] Bright artificial light in the evening can shift the internal clock and make falling asleep more difficult.
[● 5 SOURCES] A study of Swedish office workers showed annual changes in daylight intake and the daily rhythms of melatonin and cortisol.
[○ 1 SOURCE] A US study of 195 adults found average weight increased by 0.37 kg between Thanksgiving and the New Year.
[○ 1 SOURCE] During the winter, weights were on average 0.48 kg higher than in early autumn.
[○ 1 SOURCE] The body undergoes a natural adaptation to seasonal changes involving lower temperatures and less sunlight.
[○ 1 SOURCE] The body consumes more calories in cold weather to maintain its internal temperature.
[○ 1 SOURCE] Reduced sunlight exposure can impact serotonin levels, potentially causing mood fluctuations.
[○ 1 SOURCE] Cold and dry air can narrow airways and increase mucus production, worsening respiratory issues.
[○ 1 SOURCE] Asthma symptoms may include wheezing, chest tightness, or a persistent dry cough.
[○ 1 SOURCE] Reduced sunlight in autumn can increase melatonin levels and decrease serotonin levels. www.ad-hoc-news.de
