Brain Fog in Midlife

Why Does It Happen?

As oestrogen levels fluctuate during peri-menopause, so does the brain’s chemistry. These hormonal shifts can affect neurotransmitters and even blood flow to the brain. Add to that disturbed sleep, stress, and nutritional shortfalls, and it’s easy to see why your mind might feel cloudy or forgetful at times.

1. Balance Your Blood Sugar

Sharp rises and dips in blood sugar can leave you tired and mentally sluggish. To steady your energy, always pair carbohydrates with a protein or healthy fat, and choose slow-release options like whole grains, nuts, seeds and fibre-rich foods. 

2. Boost Your Omega-3 Intake

Omega-3 fats are crucial for brain function and reducing inflammation. Top up your intake with oily fish such as salmon, sardines or mackerel, or plant-based options like flaxseeds, chia seeds and walnuts. Aim for at least two portions of oily fish each week.

3. Consider Creatine for Brain Support

Research now links creatine to improved cognitive function, even helping with brain fog after illness. Look for the CreaPure label when buying; it’s tested for purity and free from contaminants. Brands like MyProtein and Bulk both stock it. It may cost a little more, but the quality matters.

4. Cut Back on Sugar

Too much sugar promotes inflammation and can interfere with concentration. Keep an eye on sweet drinks, processed snacks and desserts, and try to opt for naturally sweet whole foods instead.

5. Keep Hydrated

Even mild dehydration can dull your focus. Aim for around 6–8 glasses of water each day and sip regularly rather than gulping all at once.

6. Protect Your Sleep

Deep, restful sleep helps clear toxins from the brain and strengthen memory. Stick to a regular bedtime, avoid screens for at least 30 minutes before bed, and keep your room cool, dark and calm.

7. Soothe Stress Levels

Excess cortisol (your stress hormone) can disrupt memory and mood. Build in daily pauses such as a few minutes of mindful breathing, yoga, prayer, or time outdoors to help keep your mind clear.

8. Nourish Your Gut

Your gut and brain are closely linked. Support them both with fibre and fermented foods like yoghurt, kefir or sauerkraut, plus plenty of colourful veg, lentils and beans to feed beneficial gut bacteria.

9. Check Your Nutrient Levels

Low iron, B12, folate or magnesium can all affect brain function. Kat’s Wellness Check can identify any deficiencies or imbalances, helping you target what your body truly needs.

10. Eat the Rainbow

Brightly coloured fruits and vegetables are full of antioxidants that protect brain cells from oxidative stress. Think berries, greens, and a variety of colours on your plate every day.

11. Move Regularly

Movement increases blood flow to the brain and boosts BDNF (a protein that supports learning and memory). Strength training remains essential, but a little cardio such as short sprints or 10 minutes on a bike or stepper adds an extra lift.

12. Choose Whole Foods

Ultra-processed foods can contribute to inflammation and nutritional gaps. Stick to real, simple foods with ingredients you recognise. If the label looks like a chemistry experiment, it’s best left on the shelf.

13. Get Natural LightExposure to morning daylight helps regulate your circadian rhythm, balance hormones and boost serotonin, which supports better focus and mood throughout the day.

14. Support Mitochondrial HealthYour brain cells rely on healthy mitochondria for energy. Include foods rich in CoQ10 (such as salmon, spinach and broccoli) and polyphenols (like green tea and berries) to keep your brain energised.

15. Mindful CaffeineA little caffeine can sharpen alertness, but too much can increase anxiety and disrupt sleep. Stick to morning coffee or tea and switch to herbal infusions after midday.

16. Prioritise ConnectionSocial interaction stimulates cognitive function and emotional wellbeing. Spend time with loved ones, join a class or simply connect with others who uplift you. It makes a huge difference. 

The Bottom Line

Brain fog during peri-menopause is common, but it’s not something you have to live with. With mindful nourishment, movement and self-care, you can lift the fog, sharpen your focus and feel fully yourself again.
