What is the connection between hormones and mood swings?

Mood swings are one of the most commonly reported experiences across the menstrual cycle, and hormones play a major part in that emotional ebb and flow. Estrogen, for example, is often mood-lifting. When it rises in the follicular phase, women tend to feel clearer, more confident, more social, and more emotionally balanced.

But as estrogen dips and progesterone rises in the luteal phase, it’s normal to feel more sensitive, introspective, or easily overwhelmed. Progesterone can have a calming effect, but in combination with PMS symptoms like bloating, fatigue, or disrupted sleep, emotional fluctuations can feel amplified. If stress is high or lifestyle factors are out of balance, these shifts may feel even more intense.

The Sturdy Women’s Fitness App acknowledges that emotional well-being is inseparable from physical wellness. Sturdy’s approach to training integrates mental and emotional health by encouraging sustainable movement, promoting rest when needed, and offering options for lower-intensity workouts during more sensitive weeks. Through its supportive tone and functional structure, the app helps women feel successful—not pressured or discouraged—through hormonal mood changes.

By aligning workouts with how your body and mind are likely to feel, Sturdy helps reduce the emotional friction many women experience throughout the month.
