Environmental illness refers to health problems caused by exposure to various environmental factors, such as chemicals, pollutants, and allergens. These factors can be found in air, water, soil, and even in products we use daily. Symptoms may include headaches, fatigue, respiratory issues, and skin irritations, which can vary in severity among individuals. People with environmental illness often struggle to identify specific triggers, making diagnosis challenging. Common sources of exposure include pesticides, industrial chemicals, and mold. Treatment typically involves reducing exposure to these harmful substances and managing symptoms through lifestyle changes and medical care.
