What Causes Seasonal Depression?

About this video

Brecka explains seasonal affective disorder. He claims reduced sunlight in darker months affects brain chemistry, hormones, energy, and vitamin D status, contributing to sluggishness, oversleeping, and carbohydrate cravings, and he frames recovery and prevention as multi-directional before teasing a list of mitigation strategies.

Key takeaways

• Brecka attributes seasonal depression partly to light-driven changes in brain chemistry
• He links lower sunlight to reduced vitamin D and serotonin activity, in his explanation
• He presents SAD as biological, physiological, and social rather than single-cause
