To work or study under traditional fluorescent tubes or CFL for one day, according to various medical studies, a person absorbs as much ultraviolet light as being directly exposed to sunshine for an hour. This would likely lead to adverse changes in one’s immune systems, white blood cells and chemical bonds, and potentially DNA that would cause cancer.
