Yeah, it seems highly unlikely. Having to talk a lot on the phone gives me stress. It's odd they don't even mention the most probably reason for their finding, and invent some unproven theory about emf affecting blood pressure. The only study I can find is this: https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(98)24025-6/fulltext https://www.thelancet.com/journals/lancet/article/PIIS0140-6...
