Feeling more anxious during perimenopause is very common, but that doesn’t make it any less distressing.
Many women describe suddenly feeling:
- more overwhelmed than usual
- emotionally sensitive
- constantly “on edge”
- unable to switch off at night
- or anxious in situations that never used to bother them
For some, it can feel as though they’ve become a different person overnight.
What makes this harder is that many women don’t initially realise anxiety can be linked to hormonal changes. Instead, they may assume they are simply stressed, exhausted, or no longer coping in the way they used to.
What is perimenopause?
Perimenopause is the stage leading up to menopause, when hormone levels begin to fluctuate and gradually decline.
It often begins in a woman’s 40s, although some women notice symptoms earlier. During this time, hormones such as oestrogen, progesterone, and testosterone can become more unpredictable, affecting many systems in the body, including the brain and nervous system.
How hormones can affect anxiety
Hormones play an important role in regulating neurotransmitters — the brain chemicals involved in mood, sleep, and emotional balance.
For example:
- Oestrogen supports serotonin, which helps regulate mood
- Progesterone has calming effects through GABA pathways
- Cortisol (the stress hormone) can worsen anxiety and disrupt sleep when elevated long term
As hormone levels fluctuate during perimenopause, some women notice they become:
- more anxious
- emotionally reactive
- less resilient to stress
- or more prone to panic-like symptoms
This can happen even in women who have never experienced anxiety before.
What can perimenopause anxiety feel like?
Symptoms vary from person to person, but may include:
- constant worrying or overthinking
- racing thoughts
- panic attacks or palpitations
- irritability or mood swings
- poor sleep or waking in the early hours
- brain fog or difficulty concentrating
Many women also describe a sense of “not feeling like themselves.”
Why symptoms often worsen at night
Hormonal changes can affect sleep quality, particularly during perimenopause.
Night sweats, falling progesterone levels, stress, and cortisol changes can all contribute to disrupted sleep. In turn, poor sleep can worsen anxiety, emotional resilience, and brain fog the following day.
This can create a cycle where symptoms gradually become harder to manage.
It’s not “just stress”
Many women are told their symptoms are simply due to stress or getting older. While stress can absolutely play a role, this explanation can feel dismissive when symptoms appear suddenly or feel out of character.
Hormonal changes can significantly affect how the brain and nervous system respond to stress, which is why understanding the hormonal link can be an important first step toward feeling more like yourself again.
When to seek support
If anxiety, overwhelm, poor sleep, or mood changes are affecting your day-to-day life, particularly alongside other symptoms of perimenopause, it may be worth exploring whether hormones could be contributing.
