Brain Fog: Why You Feel Like You’re Stuck in a Mental Haze (and How to Clear It)

Ever have one of those days where you’re physically present but mentally... nowhere? Words feel slippery, decisions feel like a marathon, and even remembering where you put your keys feels monumental. That, my friend, is brain fog—a frustrating and increasingly common phenomenon in our fast-paced, hyper-stimulated world.

Let’s break it down.

What is Brain Fog?

Brain fog isn't a clinical diagnosis; it's more like a catch-all term for a cluster of symptoms such as; trouble concentrating, forgetfulness, slow processing speed and a lack of creativity / 'flow'.

Think of it as the mental equivalent of driving through thick fog: everything feels muted, unclear and an effort to navigate.

Why does brain fog happen?

The exact cause depends on the person, but here are some common culprits:

1. Sleep Deprivation

Chronic sleep issues disrupt your brain’s ability to clean up waste, process memories, and recharge. Over a third of adults in the U.S. report not getting enough sleep regularly. That’s millions of foggy minds, running on empty.

2. Stress overload

Stress hormones like cortisol are great in short bursts. But when they stick around too long, they interfere with neural pathways—particularly in the prefrontal cortex, where decisions and focus happen. Chronic stress = scattered thoughts.

3. Hormonal Changes

For women going through menopause, brain fog can be an especially frustrating symptom. Fluctuating hormone levels—particularly estrogen and progesterone—impact neurotransmitters and blood flow to the brain, leading to memory lapses, difficulty concentrating, and mental fatigue. Studies suggest that up to 60% of menopausal women experience cognitive symptoms, often paired with sleep disruptions and mood swings, making the fog even thicker.

The Science of Clearing Brain Fog

The good news? Brain fog isn’t permanent, and you can do something about it. Here are a few evidence-backed strategies:

1. Sleep Hygiene is Non-Negotiable

The magic happens during deep sleep—your brain clears out harmful waste products like amyloid-beta (linked to Alzheimer’s). Aim for 7-9 hours of quality sleep. Reduce blue light exposure an hour before bed, and keep a consistent sleep schedule.

2. Nutritional Adjustments 

Focus on whole foods / eliminate anything ultra-processed. Prioritise brain-healthy foods high in omega-3 fatty acids (oily fish and nuts), antioxidants and magnesium (leafy veg)

3. Functional mushrooms & adaptogens

No bias here at all! But functional mushrooms like Lion's Mane can support mental clarity to help lift brain fog. Improving quality of sleep through Reishi Mushroom, Adapt Relax or the likes of Passion Flower will help too. 

4. Exercise Daily

Exercise boosts blood flow to the brain, delivering oxygen and nutrients it desperately needs. Even a brisk 15-minute walk can make a difference.

Brain Fog in Modern Life

The pace of life today isn’t doing us any favors. A 2022 study found that over 60% of workers reported struggling with focus at least once a week. Between demanding schedules, lack of rest, and constant screen exposure, it’s no surprise our brains feel fried.

But the fog doesn’t have to be your norm. With small, consistent changes—better sleep, better fuel, better habits—you can give your brain the clarity it deserves.
