Part 9/12:
The episode touched on the influence of seasons, especially in regions like Scandinavia where winter light deprivation causes symptoms of Seasonal Affective Disorder (SAD)—characterized by low energy, sleep disturbances, and mood dips. Conversely, longer summer days often induce heightened energy and activity levels.
Artificial lighting and lifestyle changes have diminished natural seasonality's impact, but intentional exposure to natural light remains a key factor in maintaining healthy rhythms across seasons. Dr. Hatar criticized daylight saving time for disrupting this natural cycle, which can exacerbate health issues by forcing the body out of sync with environmental cues.
