How do hormones affect mood?

Every woman is different and so is her reaction to hormone fluctuations. Studies show that stress and overall health impact mood more than hormones, but some women experience depression that comes and goes with their period. And about 1% have a medically recognized condition known as premenstrual dysphoric disorder (PMDD). Higher levels of hormones do not cause these mood changes. It has more to do with how a woman’s body processes hormones.
