The guest on episode 18 of the Tech Outlook podcast is Kevin Lorenzen. Kevin can use a cell phone, but his wife says she physically can’t. Self-diagnosed with electromagnetic hypersensitivity, or EHS, she reports symptoms of brain fog, headaches or exhaustion when she’s around radio frequency radiation. Lorenzen, whose background is in engineering, came on the Tech Outlook podcast to talk more about the condition and how his wife lives with it.
