How to Beat Seasonal Affective Disorder (SAD) | TUH #224

About this video

Brecka explains seasonal affective disorder as a light-driven form of depression: as days shorten, he says, circadian rhythm disruption raises melatonin, lowers serotonin and vitamin D activity, producing sluggishness, oversleeping and carb cravings. He cites research he says finds bright light therapy comparable to antidepressants for SAD, while noting medication still has a role and physicians should be consulted. He then lists seven lifestyle themes he presents as mitigating SAD — morning light, movement, nutrition, consistent sleep, social connection, mindfulness and nature, and purpose and gratitude.

Key takeaways

• Brecka frames SAD as a measurable brain-chemistry response to reduced light, not weakness or laziness
• He says risk rises the farther people live from the equator
• Brecka cites reviews finding bright light therapy can rival antidepressants for seasonal depression
• He presents connection, sleep consistency and morning light as daily habits that retrain the seasonal rhythm
