Have you noticed your mood
changing in ways that feel sudden, intense, or completely out of
character?
One minute you’re calm, the next you’re overwhelmed, irritable,
teary — or irrationally annoyed by chewing, pen-clicking, or
breathing.
In this episode of the Hot & Healthy Menopause Podcast, Nicole van Hattem breaks down what’s really happening in your brain during perimenopause and menopause — and why your emotions can feel so unpredictable.
We explore the powerful relationship between hormones and neurotransmitters, including:
How declining estrogen affects serotonin (your “happy” chemical)
Why falling progesterone weakens GABA, leading to anxiety and poor sleep
How changes in dopamine impact motivation, joy, and focus
Why cortisol spikes make everyday stress feel overwhelming
Nicole explains the science in clear, relatable language — with real-life examples that will make you feel seen, not broken.
This episode also looks at how these changes can show up:
In the workplace (patience, performance, leadership, confidence)
At home and in relationships (irritability, withdrawal, decision-making)
In how you regulate stress, communicate needs, and care for yourself
You’ll learn practical strategies to:
Better self-regulate at work
Recharge after hours without guilt
Communicate what’s happening (without excusing behaviour)
Get support through coaching, therapy, and medical options such as menopause-informed care and HRT
If you’re navigating mood
swings, emotional overwhelm, or questioning yourself during this
transition — this episode will help you replace self-doubt with
understanding, compassion, and clear next steps.
