Many women who have never struggled with anxiety find themselves blindsided by it in perimenopause — racing thoughts at 3am, irritability that feels out of proportion, or a persistent sense of unease with no clear cause.
The hormonal link
Oestrogen interacts directly with serotonin and GABA, two neurotransmitters central to mood regulation. As oestrogen fluctuates unpredictably, so can your emotional baseline — independent of what is actually happening in your life.
Why this gets missed
Because anxiety and low mood are common at every life stage, they are easy to misattribute to work stress, parenting, or relationships — even when hormones are the primary driver. This can lead to treatment that addresses circumstances rather than the underlying cause.
What helps
- Naming the pattern: tracking mood alongside your cycle often reveals a clear hormonal rhythm.
- Movement: regular exercise measurably reduces anxiety symptoms, partly through its own hormonal effects.
- Sleep protection: poor sleep and anxiety feed each other; improving one often eases the other.
- Professional support: therapy, and in some cases medication or HRT, are legitimate options — not a last resort.
When to seek help
If anxiety is affecting your daily functioning, relationships, or sense of self, that is a reason to speak with a GP — not something to push through quietly. Hormonal anxiety responds well to the right combination of support.
