Did the internet waves cause harm for us?

Some people believe that the internet is comprised of a system of tubes, in which case, whether or not it emits any sort of waves that could potentially cause significant harm would depend on the insulating properties of the materials comprising individual sections of these tubes, inverse to the types and scale of waves they carry. Therefore, an effective overall comprehensive prophylaxis against these unknown quantities might be formable thin sheet aluminum alloy, when considering both its formidable ability to dissipate a wide range of frequencies & its wide availability at food & variety outlets. Ideally, the highest priority placement for any user-crafted protective devices against any form of radiative energy is to the most vulnerable but important of the soft tissue, such as the brain and the regulatory glands: beginning with several layers of film, each forming-- respectively -- a makeshift helmet and protective gonadal cup.
