As for the HAARP issues that have been affecting people..The Tin Foil Hat Theory(Yes some think its crazy) might Help or net but it needs an airing..Its been eating away all day at me that it helped in the past as well as today..Also some people sware that it helps in areas with Wifi and large phone masts with sleeping..I dont have to mention the affects of wifi here as its been well documented,was just pulling at an idea like the Faraday cage for some protection maybe..just an idea and there was something about Tin in the ancient past to if only i could rememnber..
From The Wiki..Scientific Basis
The notion that a tin foil hat can significantly reduce the intensity of incident radio frequency radiation on the wearer's brain has some scientific validity, as the effect of strong radio waves has been documented for quite some time.[3] A well-constructed tin foil enclosure would approximate a Faraday cage, reducing the amount of (typically harmless) radiofrequency electromagnetic radiation inside. A common high school physics demonstration involves placing an AM radio on tin foil, and then covering the radio with a metal bucket. This leads to a noticeable reduction in signal strength. The efficiency of such an enclosure in blocking such radiation depends on the thickness of the tin foil, as dictated by the skin depth, the distance the radiation can propagate in a particular non-ideal conductor. For half-millimeter-thick tin foil, radiation above about 20 kHz (i.e., including both AM and FM bands) would be partially blocked, although tin foil is not sold in this thickness, so numerous layers of tin foil would be required to achieve this effect.
The effectiveness of the tin foil hat as electromagnetic shielding for stopping radio waves is greatly reduced by the fact that it is not a complete enclosure. Placing an AM radio under a metal bucket without a conductive layer underneath demonstrates the relative ineffectiveness of such a setup. Indeed, because the effect of an ungrounded Faraday cage is to partially reflect the incident radiation, a radio wave that is incident on the inner surface of the hat (i.e., coming from underneath the hat-wearer) would be reflected and partially 'focused' towards the user's brain. While tin foil hats may have originated in some understanding of the Faraday cage effect, the use of such a hat to attenuate radio waves belongs properly to the realm of pseudoscience.
A study by graduate students at MIT determined that a tin foil hat could either amplify or attenuate incoming radiation depending on frequency; the effect was observed to be roughly independent of the relative placement of the wearer and radiation source.[5] At GHz wavelengths, the skin depth is less than the thickness of even the thinnest foil.[citation needed]
Tin foil hats are seen by some as a protective measure against the effects of electromagnetic radiation (EMR). Despite some allegations that EMR exposure has negative health consequences,[6] at this time, no link has been verifiably proven between the radio-frequency EMR that tin foil hats are meant to protect against and subsequent ill health.
Electromagnetic hearing
Humans are able to detect modulated radio-frequency electromagnetic signals in the microwave range, hearing them as sounds. The perceived source of induced sound is located inside of or directly behind the head of the recipient, regardless of the location of the transmitter. The effect is believed to be caused by thermoelastic expansion of the brain exposed to microwaves.[8]
During the Cold War, electromagnetic hearing was clinically studied in the United States for applications including covert message transmission and use as a non-lethal weapon. As a declassified National Ground Intelligence Center document points out:
It may be useful to provide a disruptive condition to a person not aware of the technology. Not only might it be disruptive to the sense of hearing, it could be psychologically devastating if one suddenly heard "voices within one's head".

In 1962, Allan H. Frey discovered that reception of the induced sound can be blocked by a patch of wire mesh (not foil) placed above the temporal lobe.
