What Causes Brain Fog? 12 Possible Causes You Should Know

Asthma and Allergies

Asthma is a disease affecting the lungs and a person’s proper breathing. The air passage becomes narrow and swollen, resulting in shortness of breath, chest tightness, a whistle-like cough, and recurring breathing gaps. Like other diseases, one cannot cure asthma, and few medications can only control its symptoms through medications. This disease is developed and triggered through tobacco smoking (primary, secondary or third-hand smoking), air pollution, pests and specks of dust, the pungent smell of chemicals, and toxic wastes. 

On the other hand, allergies are also triggered by the same substances found in the air (cigarette smoke, dust, pollens, and polluted air) and tiny particles, just like asthma. Allergic reactions may be manifested in the form of skin rashes, persistent sneezing, breathlessness, throat tightness, itchiness throughout the body, and inflammation. When a person experiences allergic reactions, it triggers the release of the chemical called histamine. This chemical is associated with the cognitive functions that regulate learning and motivation. However, too much histamine could be dangerous and could result in many symptoms, like sneezing, coughing, and brain fog. To stabilize it, take a low diet to food intake and improve health.
