Nobody is askin you to believe anything a-priori. The point here is that we haven't looked into what the affects mean. The sun puts out considerably less radio emission than it does any other EMR (xray, UV, visible, infrared). Many of the wavelengths are then deflected, absorbed, weakened, etc by the atmosphere. Logically speaking, if the wavelength that we use for forms of radio communication make it to earth, then we would need to transmit at a higher power to overcome that background noise. Again, logically speaking, when the tests are being done, the observation in increased glucose consumption etc are being observed over the natural baseline affects of the sun.
