Brain Fog Damages Your Work Productivity.

 The Interrelationship Between Mental Fatigue and Physical Fatigue

“ You were saddled with a million projects [….]. You know you said you’d go to the gym after work, but you’re wiped out […] You had a hard day, but it was hard mentally — you were sitting down for most of it. Well, all that stuff they say about the mind-body connection is real. Research shows that mental fatigue really does lead to physical fatigue. It’s obvious that when your brain is tired, you’re not as mentally sharp.” There’s a Reason Your Body Is Tired When Your Brain Is Fried, Ashley Hamer


Scientists found that mental fatigue highly affects physical performance. In 2009, Samuele M. Marcora and his team at Bangor University in Wales published a study in which they had people ride a stationary bike to exhaustion after spending 90 minutes either doing a mentally demanding computer exercise or watching a boring documentary.


The participants weren’t able to pedal for as long after doing the cognitively demanding computer task as they were after watching the documentary. They also reported higher feelings of physical exertion on the post-computer-task ride.


Mental Fatigue Lower Physical Endurance

They concluded that mental fatigue lower physical endurance. For a study published in June in Sports Medicine, Australian and Belgian researchers examined a hypothesis put forward in 2014 and confirmed that adenosine[1] is the chemical to blame.


As the brain gets tired, it demands rest. Do not beat yourself up too much. The idea is that when you do something that’s mentally taxing, your brain burns through glucose, it utilizes sugary chemical as a fuel. As glucose levels drop, levels of adenosine rise, which blocks the release of the neurotransmitter dopamine. Essentially, dopamine plays a deciding role in goal-seeking behavior. When dopamine can’t operate properly, you would be less motivated to keep working on the task at hand, which force your brain to stop working and recharge yourself first. 

Exercise and Brain Cell Growth

Regular Exercise Improve Memory and Avoid Brain Fog



Exercise Increase and boost the size of our hippocampus in the brain.[3]

The hippocampus is critical for the formation of new memories.

Hippocampus is involved in transferring information from short-term memory to long-term memory. In a study executed at the University of British Columbia, researchers found that regular aerobic exercise makes our heart and sweat glands [4]pumping and able to boost the size of the hippocampus[5], in which is situated in the brain area which involves in verbal memory and learning.


Nevertheless, resistance training, balance, and muscle toning exercises did not lead to the same results.

Many elder people suffer from a deteriorating hippocampus, which often results in memory loss and disorientation. This review suggests that aerobic exercise help prevent dementia and common health problems.



Other Health Benefits of Regular Exercise

  1. Reduce the odds of developing heart disease, stroke, and diabetes.
  2. Exercise protect and improve memory and thinking skills.
  3. Counter against brain fog which might lead to chronic fatigue.

Aideen Turner, a physical therapist, uses exercise to combat brain fog. “Research has proved the effects of exercise on our cognition. Exercise increases the blood supply or ‘food’ to our brain. …

  1. Reduce insulin resistance[6]
  2. Reduce inflammation
  3. Stimulate the release of growth factors. Studies found that chemicals in the brain affect the health of brain cells. Researchers assert that every four seconds have another new case of dementia on a global scale. They estimate that there will be more than 115 million people have dementia worldwide by 2050.

Regular exercise somehow improves mood and sleep, which is able to reduce stress and anxiety.


Brain fog stops people from performing their best at work.

If you find yourself feeling “foggy” quite often, you’re probably experiencing brain fog. The hallmark characteristics of brain fog include the difficulty of concentrating, being forgetful and more.


Behavioral neurologist Dr. Mary Ellen Quiceno asserts that brain fog can be “ brief and fleeting or it can be continuous.”


There are many possible causes might lead to brain fog, including insomnia, certain medications, stress and mood disorders, thyroid[1] and metabolic disorders and chronic pain like fibromyalgia[2] or even frequent migraines.


ER doctor Dr. Darria Long Gillespie “Our brain makes up only 2 percent of our body weight but consumes 20 percent of our total energy. So a problem anywhere else in the body is often reflected in a feeling of diminished brain functioning or brain fog.”


Figure Out the Primary Cause

Gillespie argues that the best way to deal with brain fog is to find its primary cause. Autoimmune illness or diabetes are the most likely culprit for the fogginess in the brain.


Chronic Stress is a  Common Cause of Brain Fog

According to a 2017 Gallup poll, 80 percent of Americans report feeling stressed either frequently or sometimes.

Nothing functions well when we’re having long-term sleep deprivation. Gillespie emphasizes the importance of sufficient sleep. Exercise and mindfulness breathing exercises help people to sleep better.


Most often, brain fog is a reminder that you should take better care of yourself and pay more attention to your body.  

SUGGESTION: Quit unhealthy habits like burning out the midnight oil or digest tons of fried food or regular binge eating or stress eating.

I tend to unveil the issues which are easily neglected by the mainstream public. Situated in a global capitalist society, the core spirit of capitalism disseminates a reward-oriented idea. What is the underlying causality of universal bullying phenomenon on the worldwide scale? As to Finland’s anti-bullying program “Kiva,” what do you reckon? Self-serving politicians gross over their wickedness by law or something and they are talented at outwitting the crowds and working for their own advantage with flat-out lies.
