Why am I getting all these medical questions? I only wear a lab coat to get a better parking space. Like cell phones and laptops, CFLs give off electromagnetic fields (EMFs). Many studies report that the levels given off by consumer electronics, wireless networks and power lines are within a safe range. Dr. Havas connects these EMFs with many symptoms, including migraines, burning eyes, digestive problems, heart palpitations, immune system disorders, diabetes and even multiple sclerosis. According to Havas, this Electrical Hypersensitivity (EHS) may affect about 3 percent of the population. So far, however, no research has proven that EMFs from CFLs impact the majority of people.
