That's the problem right there, a little bit of knowledge is a dangerous thing. At the risk of getting into a physics 101 course...
The sun is a massive source of non ionising em radiation, but it is also a massive source of harmful ionising radiation, particularly at ground level ultraviolet but if you're in space gamma and x-ray frequencies too. We will ignore neutrinos and cosmic rays or you really will want to start wearing a tin foil hat. The stuff that burns you, and me and my freckly kids especially, is the ionising uv radiation. Visible light frequencies from the sun at earth just don't have the energy or intensity to ionise.
Ultraviolet emitted from the sun is known to be harmful, it has the ability to change molecular structures and even cause cancerous mutations of tissue. Gamma and X-rays are higher energy still and have a correspondingly stronger effect.
The electromagnetic spectrum spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. They are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
Then you have to factor in intensity, or effectively em density. 92million miles from the sun we have a relatively low intensity of all spectrum em radiation. The intensity is inversely proportional to the square of the distance from the source, and directly proportional to the power of the source. The exception is laser light, as that is highly organised and not from a point source.
The gadgets and EM sources around the house are generally emitting very low energies of low frequency em radiation, mostly in the radio wave part of the spectrum but occasionally microwave. Really hot things will also emit some infrared, whilst only things getting really very excited will emit visible light. Unless you have a gadget specifically designed to emit UV, like a bank note checker or a bad sunbed, there should be nothing harder than visible light in the house. Very powerful lasers in the visible light spectrum can ionise, but it is unlikely you would have anything that powerful in a house or even normal workplace.
So as far as em is concerned, anything below artificially manufactured intense laser light simply does not have the energy to do anything on a molecular level. In fact humans are also emitters of em radiation in several parts of the spectrum.
I can't prove to you it does nothing, its extremely hard to prove a negative result as you would have to test absolutely everything, but what I can say is there is zero scientific evidence that low energy / frequency and low intensity em radiation has any effects on a human body, harmful or otherwise.
As for the pacemaker, the induction hob works by creating a specific magnetic field. A pace maker has electrons flowing in its circuits that could potentially be effected by the magnetic field created, possibly disrupting the normal operation of the pacemaker. Exc
