About Brain Fog:


  • Brain fog itself is not a medical condition but instead a symptom of other medical conditions.
  • It is a term used to describe a variety of symptoms that can affect your ability to think clearly.
  • Brain fog is characterized by confusion, forgetfulness, and a lack of focus and mental clarity.
  • Some examples of things a person might do because of brain fog include:
    • forgetting about a task they had to complete;
    • taking much longer than usual to complete simple tasks;
    • feeling frequently distracted;
    • feeling tired when working;
  • Causes: Brain fog is typically rooted in a lifestyle that promotes hormonal imbalances.
    • Electromagnetic radiation – from computer, mobile phone, tablets
    • Stress – reduce blood flow to the brain causing poor memory
    • Lack of sleep, no exercise
    • Diet: food allergies or sensitivities
    • Toxins, pollution, chemical substances, and insecticides
    • Medications
  • Treatment: Treatment depends on the cause. For example, if you’re anemic, iron supplements may increase your production of red blood cells and reduce your brain fog.

Hormones are chemical messengers produced by various glands and tissues in the body. They play a crucial role in regulating and coordinating various physiological processes and maintaining the body's internal balance, known as homeostasis. Hormones are secreted into the bloodstream and travel to target cells or organs, where they exert their effects by binding to specific receptors.
