Are You Brain Fatigued

It is a very normal reaction to feel stressed, fearful, anxious, and worried about an uncertain future, financial pressures, job security, social isolation and a totally different way of living during this ongoing Corona-Pandemic.
However ongoing and unmanaged stress can wreak havoc on our physical health, mental health, our mindset, the way we react to situations and people,  and our ability to make good decisions.

In fact, the associated stress and anxiety resulting from this pandemic can leave us totally exhausted.

The organs with the most ‘energy-hungry’ cells will be the first to feel the brunt of an energy crisis. Thus our brain is the first to feel the effects of low energy.  Our brain only makes up 2% of our body weight but uses 20% of our energy. 
No wonder when we are fatigued the things we notice are brain fog, poor memory, impaired word recall and decreased executive function. These are common complaints we are currently hearing from many of our customers in-store and patients in our clinics.
Many are worried about their declining cognitive function but, rest assured this is a very common physiological response in these unprecedented times..

If you would like to learn more about your stress response during our current Social Isolation and how best to manage it, make yourself a cuppa and listen to our Naturopaths talk about this at our recent Webinar.

We know that stress is a leading ‘energy-zapper’ and it leads to systemic inflammation throughout the body. Chronic, untreated stress leads to chronic inflammation which leads to brain fatigue. 
The hallmark feature of those who experience long-term fatigue is neuro-inflammation and this alters the brain landscape.

Brain imaging studies show marked atrophy in various brain regions of people who are fatigued, which basically means that the brain changes in fatigued states.
Stress also causes different parts of the brain to either shrink or grow as it responds and adapts to stress.

Let’s look at some of the main players


This is the brain region most recognised for its role in memory, learning and adding emotional context to events. It is used in decision making and is continually forging new neural connections to create and save memories. It is highly vulnerable to damage due to it being a very plastic brain region (neuroplasticity).

Pre-fontal Cortex

The pre-frontal cortex is responsible for rational thinking, stable emotions and executive function. It rationalises things to reduce fear.
You might identify with a time when you were highly stressed and found you just couldn’t think straight. This is the overwhelming effect of stress on your pre-frontal cortex and thought processes.


The Amydala is our emotional memory responsible for fear and worry.
The simple act of just thinking about an old event or situation sparks fear. This is the irrational processing of the amygdala at play.
It won’t surprise you then that the bigger the Amydala, the bigger the emotional response.

What’s really interesting is that studies show that stress and anxiety causes atrophy (shrinking) of the hippocampus and pre-frontal cortex. This atrophy leads to reduced function of these parts of the brain. Essentially the function which would normally tell us that ‘everything will be alright’ to an ensuing dysfunction of a state of further worry, anxiety and sadness.

Studies have also shown that chronically fatigued people have enlarged regions of the brain, namely the Amydala which is responsible for fear and worry. Thus the longer we remain in a fatigued state the higher the risk of us worrying even more, becoming more fearful and experiencing more irrational emotional responses.

It’s a bit of a catch-22 really.  If we do not prioritise our energy and our stress management then the old adage that “anxiety breeds anxiety” may ring true as our Hippocampus and Pre-frontal Cortex is shrinking whilst our Amydala is growing.

However reducing stress and creating more energy is easier said than done in our busy, time-poor lifestyles. Often working with a Naturopath or depending on your state of readiness, a Wellness Coach can help you move to a life of optimum health and wellness. But in the meantime here are our top nutrients for Stress and Energy

Nutrients for Stress & Energy

1. B-group vitamins

The B-group vitamins are critical for energy production and reduce hypertrophy (shrinking) of the brain. B12 is also implicated in neuroplasticity.

2. Magnesium

Magnesium is essential for a healthy brain as it maintains mitochondrial structure and function

3. Co- Enzyme Q10

Our mitochondria are often referred to as the “powerhouse” of the cell and are responsible for creating our energy.
Mitochondrial dysfunction is central to fatigue and emerging leaders in Complementary medicine believe that mitochondrial therapy is the future of Holistic medicine.
Co-Enzyme Q10 or Ubiquinol which is the preferred form, is essential for energy production

4. Acetyl L Carnitine

Acetyl L Carnitine is neuroprotective as it improves fatigue and cognitive function.

5. Adaptogens

Our beautiful Adaptogen-herbs help protect the body in the face of stress.
Our favourites are Rhodiola which has shown to reduce fatigue; the ginsengs (i.e. Panax ginseng and Siberian ginseng) which protect the brain and mitochondria and Withania which is anti-inflammatory, neuroprotective as it protects the brain from oxidative stress.
