Why do shorter days and less sunlight trigger Seasonal Affective Disorder for some people?
In short: As winter approaches, many people dread the shift toward shorter, darker days. This video explores how the transition from summer to winter impacts our internal body clocks and why this disruption can lead to Seasonal Affective Disorder.
Our internal circadian rhythms are responsible for regulating our sleep and wakefulness cycles. When the amount of sunlight decreases during the transition to winter, these biological clocks must adjust to the change in daylight.
For some individuals, this adjustment process is not seamless, potentially triggering Seasonal Affective Disorder. The video examines the connection between these environmental shifts and the resulting impact on human mood and behavior.
