You've always been able to handle stress. Then, out of nowhere, things feel different. You're worrying more than usual. Your heart races before a meeting. You wake in the night with your mind spinning. Situations that never used to bother you suddenly feel like too much.

If that sounds familiar, you're not alone — and you're not imagining it. Anxiety is one of the most common signs of perimenopause and menopause. For some women it even shows up before hot flushes or irregular periods.

What's actually happening

Menopause anxiety isn't "all in your head." As estrogen shifts, it affects the brain chemicals that steady your mood, emotions and stress response — so you might feel more worry, nervousness, racing thoughts, panic-like moments or trouble switching off. For some women it feels unlike anything they've experienced before.

Why hormones do this

Estrogen helps regulate the neurotransmitters behind how you feel:

  • Serotonin — often called the feel-good chemical, it helps steady mood, sleep and emotions
  • Dopamine — tied to motivation, reward and pleasure
  • GABA — helps calm your nervous system and dial down anxiety

When hormone levels swing, these systems get less stable, leaving you more sensitive to stress and emotional triggers.

What menopause anxiety can look like

  • Worrying more than usual
  • Feeling constantly on edge
  • Racing thoughts
  • Restlessness
  • Trouble concentrating
  • Feeling overwhelmed by everyday things
  • Panic attacks
  • More sensitivity to stress
  • Irritability
  • Trouble sleeping

It can show up physically too — heart palpitations, muscle tension, digestive upset, sweating or dizziness.

Why it often feels worse at night

Many women notice anxiety peaks in the evening or early hours. Hormonal shifts, poor sleep, night sweats, rising cortisol and fewer daytime distractions all play a part. Waking at 3 or 4 AM with a racing mind is a very common perimenopause experience.

What often comes with it

Menopause signs rarely travel alone. Alongside anxiety you might notice disrupted sleep, fatigue, brain fog, irritability, hot flushes, low libido and mood swings. Because they feed one another, easing one often helps several.

What helps

  • Prioritise sleep — less sleep makes your nervous system more reactive, so this is often the highest-leverage change
  • Move regularly — it lifts mood, lowers stress hormones and builds resilience
  • Ease off caffeine — sensitivity often rises in perimenopause, and cutting back can calm nervousness and palpitations
  • Practise stress management — breathing, mindfulness, yoga or journalling
  • Get professional support if anxiety is affecting your quality of life
