Mindfulness for Perimenopause Brain Fog: Finding Clarity in the Haze

If you’re in your 40s or 50s and you’ve started putting your keys in the fridge or blanking on names you’ve known for decades—you’re not losing the plot. You’re just human. And very possibly perimenopausal.

Perimenopause brain fog is real, common, and understandably frustrating. That foggy, forgetful, slightly-off feeling? It’s often fuelled by hormonal changes, broken sleep, stress, and the general chaos of life. (Who knew thinking could be so exhausting?)

The kind news? You don’t have to push through it alone. Mindfulness offers gentle, practical ways to clear a little space in your mind—and no, it doesn’t involve becoming a monk or turning your living room into a Zen den.

What Causes Perimenopause Brain Fog?

Those fuzzy-brain moments have a science-backed reason (not just “getting older” – promise). During perimenopause, several things can mess with your mental sharpness:

• Estrogen fluctuations – Oestrogen plays a key role in brain function. When levels drop, so can your memory and focus.
• Interrupted sleep – Night sweats, insomnia and tossing about at 3am all take a toll on your ability to think clearly the next day.
• Stress and anxiety – Hormonal changes can increase emotional sensitivity and make it harder to concentrate.
• Blood sugar dips – Thanks to hormonal shifts, your blood sugar might swing more than usual, which can zap energy and fog up your thoughts.

It’s a lot, isn’t it? But here’s the thing: mindfulness can help. Not by fixing everything overnight, but by offering you small, manageable ways to feel more steady and present—even on the foggy days.

How Mindfulness Can Help with Brain Fog

Mindfulness isn’t about emptying your mind (who has the time or brain space for that?). It’s about gently bringing your awareness to the here and now, which can do wonders for focus, stress, and emotional balance.

Here are three low-effort but high-impact mindfulness practices you can try—even if your brain feels like it’s full of porridge.

1. Box Breathing for Mental Clarity

✔ Best for: Calming the mind and improving focus
✔ How to do it:

• Inhale for 4 counts
• Hold for 4 counts
• Exhale for 4 counts
• Pause for 4 counts
  Repeat a few times

✔ Why it works: This technique helps regulate your nervous system and brings more oxygen to your brain—perfect when you’re feeling foggy, frazzled or halfway through a sentence and completely forgotten where you were going with it.

2. Mindful Walking to Boost Brain Function

✔ Best for: Re-energising the mind and body
✔ How to do it:

• Go for a gentle walk (even just around the garden or kitchen)
• Pay attention to your feet hitting the ground
• Notice the sights, sounds, smells—even if it’s just the neighbour mowing again

✔ Why it works: Walking naturally increases blood flow to the brain, and adding mindfulness helps cut through the noise in your head. A small reset without needing a holiday.

3. The 5-4-3-2-1 Grounding Technique

✔ Best for: When your brain feels like a browser with 37 tabs open
✔ How to do it:

• Name 5 things you can see
• Touch 4 things nearby
• Listen for 3 different sounds
• Notice 2 things you can smell
• Think of 1 thing you’re grateful for

✔ Why it works: This grounding technique brings you out of your head and back into the present. It’s especially useful when you’re feeling scattered, overwhelmed, or just wondering why you walked into the room again.

Kindful Last Thoughts

Let’s be honest—perimenopause brain fog is no fun. But it doesn’t mean you’re broken, failing, or falling apart. It means your brain is doing its best while your body goes through a complex hormonal shift.

Mindfulness offers a kind, doable way to support yourself through it. Just a few minutes of conscious breathing, walking or grounding can help you feel clearer, calmer and a little more like yourself again.

You don’t need to get it perfect. You don’t need to do it every day. Just start where you are, with the brain you’ve got, and a big dose of self-compassion.
