It's just 10 in the morning and already feels sleepy, and tired, or it takes longer to learn and recall information. These can be symptoms of Brain Fog, which can be defined as Mental fuzziness caused by lack of sleep or even an underlying illness.

With this article let’s take an insight into the causes, symptoms, precautions, and treatment of Brain Fog.

What is a Brain Fog?

The phrase is frequently used to refer to a collection of enduring symptoms, such as trouble concentrating, mild confusion, "fuzzy" or sluggish thoughts, forgetfulness, and a general feeling of exhaustion. The majority of people occasionally experience these sensations, but if they persist over time, they may have an adverse effect on one's quality of life. High levels of inflammation and changes in the hormones that control your mood, energy, and focus are the causes of it. Hormone imbalances further throw the body's systems out of balance and can also cause obesity, irregular menstruation, and diabetes mellitus.

What are the causes of Brain Fog?

It might result from minor structural or functional damage to the prefrontal cortex, a region of the brain that is involved in cognitive functions like planning and decision-making. Stress amplifies brain fog, which is typically caused by a lifestyle that encourages hormonal imbalances.

  1. Electromagnetic radiation from computers, mobile phones, tablets
  2. Stress reduces blood flow to the brain causing poor memory
  3. Lack of sleep, no exercise.
  4. Diet amino acids, vitamins, minerals, and antioxidants
  5. Toxins, pollution, chemical substances, and insecticides

According to a 2022 study that appeared in the journal Nature, COVID-19 can lead to abnormalities and 2% faster grey matter loss in the prefrontal cortex, among other parts of the brain. People's cognitive abilities may then be impacted by this.

The good news is that brain fog is typically treatable. The first step in treating brain fog is to determine its underlying cause. If mental confusion is brought on by stress or lack of sleep, getting a good night's sleep can help. Additionally, making lifestyle adjustments like exercising, eating healthily, and challenging one's mind with puzzles can help reduce some cognitive cloudiness.
