Hormones influence nearly every system in the body; metabolism, sleep, energy, and especially mood. For many women, emotional shifts can feel sudden or seem to come out of nowhere. In fact, they often reflect real, predictable biological patterns. Understanding these patterns can help women reduce self-blame, communicate their needs more clearly, and recognise when psychological support or medical evaluation may be useful. As therapists, we see how often women pathologize themselves for what is, in part, normal hormonal variability. This article highlights the main hormonal influences on mood and how they interact with stress, trauma, and daily life.
The Menstrual Cycle: A Monthly Emotional Landscape
Oestrogen
- Typically rises in the first half of the cycle (follicular phase).
- Often associated with improved mood, motivation, and mental clarity.
- Can enhance serotonin and dopamine activity, which contributes to feelings of well-being.
Progesterone
- Rises in the second half of the cycle (luteal phase).
- Has a calming effect for some women, but for others contributes to irritability, low mood, or emotional sensitivity.
- Sudden drops in progesterone and oestrogen before menstruation can contribute to PMS or, in some cases, more severe PMDD, which includes intense mood swings, depression, and anxiety.
Tracking cycle-related mood patterns can help identify when emotional shifts are hormonally influenced rather than signs of failure or instability.
2. Hormones and Stress: The Cortisol Connection
Cortisol, the body’s main stress hormone, interacts with reproductive hormones in ways that can amplify emotional experiences.
- Chronic stress can disrupt the menstrual cycle and intensify mood symptoms.
- Many women report of feeling more anxious, overwhelmed, or fatigued during times of hormonal fluctuation when stress levels are also high.
- From a therapeutic perspective: Supporting self-regulation, boundary-setting, and stress reduction can significantly ease hormone-related emotional shifts.
3. Mood Changes Across Reproductive Life Stages
Adolescence
Hormonal surges paired with identity formation and social pressures can make teens especially sensitive to emotional dysregulation.
Pregnancy
Oestrogen and progesterone soar, leading to:
- Heightened emotional responsiveness
- Increased need for rest and support
- Potential vulnerability to perinatal anxiety or depression, especially in those with a history of mood disorders
Postpartum
Rapid hormonal drops combined with sleep disruption and new-parent stress can contribute to:
- Maternity blues (common and short-lived)
- Postpartum depression or anxiety (more persistent, requiring attention)
Perimenopause
This transition often brings:
- Unpredictable hormone fluctuations
- Mood swings
- Irritability
- Increased anxiety
Women frequently describe feeling “not like myself,” which can be deeply unsettling without proper understanding.
Menopause
While hormone levels are lower overall, emotional steadiness often returns once fluctuations settle.
4. Hormones Don’t Act Alone
Hormones influence mood, but they don’t determine it. Psychological factors intertwine with biology:
- History of trauma can increase sensitivity to hormonal shifts.
- Internalised expectations (e.g., “I should be on top of things”) intensify distress.
- Relationship dynamics often become flashpoints during hormonally sensitive times.
- Sleep, nutrition, exercise, and social support all modify hormonal effects.
This means that therapy and lifestyle changes often significantly reduce hormone-related symptoms, even when biology is part of the picture.
5. How Therapy Can Support Clients
1. Self-Compassion Over Self-Criticism
Reframing hormonal mood changes as biological patterns, not personal flaws to reduce feelings of shame.
2. Emotional Regulation Strategies
Mindfulness, grounding techniques, and cognitive reframing can be especially helpful during hormonally vulnerable phases.
3. Tracking Patterns
Encouraging clients to track mood, sleep, and cycle patterns can empower them to anticipate shifts and plan accordingly.
4. Communication Skills
Helping women articulate their needs to others, during sensitive times in their cycle, can transform relationship dynamics.
5. When to Seek Medical Input
If mood symptoms are severe, disruptive, or cyclical, a medical evaluation for PMDD, thyroid issues, or perimenopause-related changes may be appropriate.
Conclusion
Hormones play a significant role in women’s emotional experiences, but they are just one piece of a larger mind-body system. When women understand the predictable patterns behind their emotional shifts, they can respond with insight and self-care rather than self-blame. Therapists can support this awareness, helping women move toward greater emotional stability and empowerment.
