It’s Not Just Your Hormones

If you’re in perimenopause and noticing increased irritability, emotional overwhelm, anxiety, or a shorter fuse, you may have been told — directly or indirectly — that it’s “just hormones.”While hormones absolutely play a role, this explanation is incomplete and often minimizing.

Perimenopause is a significant transition that affects far more than reproductive health. Fluctuations in estrogen and progesterone directly impact the nervous system, stress response, sleep, mood regulation, and emotional resilience. As these hormonal shifts occur, many people experience a reduced window of tolerance — meaning everyday stressors can feel louder, heavier, and harder to manage.

This is where emotional regulation often becomes more difficult.Reactions may feel faster, stronger, or harder to recover from. Small disruptions can trigger outsized responses. Emotions may feel closer to the surface, and coping strategies that once worked may suddenly feel ineffective.

The triggers are real.The distress is real.And this is not a personal failure.

Hormones influence how the nervous system processes threat, safety, and stimulation. During perimenopause, the body has fewer internal buffers. Add in chronic stress, trauma history, caregiving demands, work pressure, sleep disruption, or neurodivergence, and the system can become overwhelmed more easily.

It’s also important to name that perimenopause often coincides with complex life stages — parenting adolescents, caring for aging parents, career transitions, relationship strain, or cumulative burnout. These contextual stressors matter. When hormonal changes lower nervous system resilience, existing pressures can feel unbearable.

This isn’t about needing to “calm down” or “push through.”It’s about understanding what your body and nervous system are communicating.

Support during perimenopause may look different than it did earlier in life. Emotional regulation skills, nervous system support, therapy, medical care, and lifestyle adjustments can all play a role. Compassion, flexibility, and validation are not luxuries — they are necessary supports during this transition.

If you’re feeling unlike yourself, more reactive than usual, or emotionally exhausted, you’re not imagining it. And you’re not alone. With the right support, it’s possible to better understand these changes and build steadier ways of coping during perimenopause and beyond.
