Get Better Mental Focus – Know What Causes Brain Fog

What Causes Brain Fog?

1. Stress

Brain fog can derive from stress. It is not unpredictable to attribute this common tension to what causes brain fog. Stress can cause and exacerbate headaches, drag emotional states down, lead to depression, and deteriorate the immune system. With all these effects of stress triggered and accumulated, your brain is worn out, which consequently leaves you feeling cloudy.

To reduce stress caused by heavy loads of work or study, you should find a point where you can balance between working and resting. Working too hard and trading off your health is just not worth it, right?


2. Sleep Deprivation

Sleep deprivation can be one of the reasons your brain is feeling sluggish. Lack of sleep can cause your brain to suffer from an inability to concentrate, difficulty memorizing, and frequent forgetfulness. It is understandable why sleeping too little causes brain fog. Most people need at least 7 hours of good-quality sleep each night. Good-quality sleep is not only about the number of hours in bed. It is also about feeling refreshed both physically and mentally when you wake up. People with insomnia do not get the benefits of getting enough sleep, thus fall into some unhealthy conditions, including brain fog.

Sleeping well helps reduce stress and improve mood, think more clearly, and make good decisions. In contrast, lying around in bed without proper rest causes damage to the brain.


3. Food Allergies or Sensitivities

If there are foods that you are allergic to, they may contribute to what causes brain fog. MSG or monosodium glutamate can be one of the ingredients that you may want to avoid at your dining table. MSG is commonly known as a flavor enhancer in cooking. It can be found naturally in some foods, including tomatoes and cheese.

Suppose you experience some effects of MSG, such as headache, after 20 to 25 minutes. In that case, you are likely to be sensitive to this ingredient.


4. COVID-19

Another culprit of brain fog is pneumonia, or COVID-19. The most commonly seen symptoms of COVID-19 include high body temperature, constant coughing, fatal shortness of breath, and fatigue. You probably never associated brain fog with COVID; however, it has been recently found that some people with COVID-19 also suffered from cognitive impairment. These people reported that even after other symptoms of COVID had gone away, the feeling of sluggish brain performance lasted weeks later.

The reason why coronavirus can impair your brain is that this virus, as a neuro-invasive virus, can enter and deteriorate your brain tissue.


Symptoms of Brain Fog

The term “brain fog” refers to a symptom, not a medical condition. Different people will experience it differently, and they may use the same term to describe various symptoms. The following are some of the symptoms of brain fog:

  • Feeling drained
  • Feeling “spacy” or perplexed
  • Slower-than-usual thinking and a need for extra time to execute simple tasks
  • Being prone to distraction
  • Having difficulties putting your thoughts or activities into order
  • Forgetting daily activities or losing one’s line of thought are examples of forgetfulness
  • Struggling with finding words

Brain Fog Treatment

There is no specific treatment for brain fog because it is a symptom rather than a medical diagnosis. Managing anxiety, or the issues that cause it, may, however, be beneficial.

The following are some possible treatment options:

  • Medication, such as anti-anxiety medication
  • Natural medicine, such as supplements like DHH-B – dihydro honokiol-B, a natural supplement that has anxiolytic effects
  • Sleep aid like Melatonin calms the mind and prepares the brain before sleep
  • Psychotherapy, talking about anxiety, and developing coping skills
  • Support groups
  • Time management strategies to help a person stay focused
  • Changes to school or work, such as extended test-taking time
  • Breathing, meditation, and exercise


Drinking water, getting enough sleep, and eating well can help prevent brain fog. This is especially beneficial for persons who suffer from worry that prevents them from taking care of themselves.

Specific self-care practices may also be beneficial to some persons. Some examples are following a timetable, utilizing a reminder app, or taking frequent breaks from whatever is causing anxiety.

There are even more explanations for why your brain does not feel up to what it is capable of. The important thing is that you have to identify the underlying cause. Once the culprit has been identified, you can turn the undesirable situation around back to its normality.
