7. Understanding Seasonal Affective Disorder | Why Winter Feels Heavy
In this episode of MOHIvate, Dr. Mohi Sarawgee breaks down Seasonal Affective Disorder (SAD) -> the winter drop in mood, energy, and motivation that affects millions each year.
With a blend of science, psychology, and everyday language, she explains why shorter days and longer nights change our brain chemistry, why cravings and fatigue increase, why motivation disappears, and why none of this means you’re “weak,” “lazy,” or “unmotivated.”
You’ll learn:
•how light affects serotonin, melatonin, mood, and sleep
•why Vitamin D matters in winter
•why winter cravings are biochemical, not lack of discipline
•simple, realistic steps that actually help - from light exposure to nutrition and routine
•when SAD is mild vs. when it needs medical support
This episode is a gentle, science-backed reminder that winter isn’t a failure season - it’s a recalibration season.
If you’ve been feeling slower, heavier, more emotional, or “not yourself,” this conversation will help you feel understood, supported, and a little more hopeful.
