Electromagnetic EMF Shielding Canopies

NB: Electricforester has no association with electrosmogshieldingcanopies or companies of a similar name.
Taking steps to reduce total electromagnetic exposure is now normal for many people, especially those who may be ES (ElectroSensitive) and do not want to become EHS (Electromagnetically HyperSensitive). One significant way of helping to achieve this simply and quickly is by investing in a shielding canopy that covers both the bed and its occupant(s) at night. Exposure to electromagnetic pollution - 'Electrosmog', particularly where one sleeps is especially damaging. During the day, the body is set-up for action. During the night, the body is geared for recovery and repair. Many people today experience disturbed sleep and wake up frequently during the night for no apparent reason. Exposure to electrosmog, especially at night, not only disturbs sleep but it appears to interfere with detoxification. Stressed cells are likely to have compromised metabolism and reduced ability to neutralize toxins. The pineal gland is active when light (which is another form of electromagnetic radiation) is absent. It controls production of Melatonin (a powerful anti-oxidant) which is important in the detoxification process. Night time exposure to light, or electrosmog, suppresses Melatonin production. Research into how and why is on-going but you don’t have to be fully conversant with the biochemistry to appreciate your body’s need for a good nights sleep.
Rebound Effects:
When people are able to sleep deeply in the electromagnetically sanitized environment that is created by a shielding bed canopy, their bodies heave a sigh of relief and start to detoxify properly, perhaps for the first time in years. Paradoxically, this can make them feel worse for a few days, until their bodies let go of some of their historic toxic load and re-stabilise. When this happens, the depth and quality of sleep they experience can be surprising and initially even a little frightening. So used have their bodies become to shallow sleep, that when they re-experience the deep satisfying uninterrupted sleep their bodies have craved for so long, it can at first be a bit unsettling. Within a short time however, most people come to love the new peace and tranquillity they experience in their shielded beds.

New Developments:
Domestic electromagnetic shielding canopies are a new innovation, created out of necessity and experience of using them to best effect is still evolving. People who are seriously affected by exposure to electrosmog generally need to achieve immediate respite. During the all-important hours of sleep, increasing ambient levels of radio frequency radiation are now attacking everyone and shielding canopies provide a quick and effective solution. The roll-out of mobile phone networks, digital terrestrial television, home-hubs, cordless phones and new upcoming airborne/satellite systems mean that everyone’s RF exposure is rising and for those who cannot tolerate even today‘s levels, protection at night is likely to become increasingly necessary.
However, initial relief may wane over time and growing experience of the longer-term effects of continually sleeping inside a fully enclosed shielding canopy suggest that some further understanding of their properties is needed. It now appears better not to sleep in a totally enclosed Faraday Cage every night, forever and some temporary cessation appears beneficial, at least for some, even if total protection is reduced.
One does not have to be scientifically or medically orientated to recognize that the balance of both positive and negative ions that exists in outdoor air, is beneficial. It seems reasonable therefore that any disturbance to this natural balance indoors is probably not without some disadvantages.
Air can pass with varying amounts of freedom through electromagnetic shielding fabrics such as Chromax EMF / Daylite, Naturell, Swiss-Shield Evolution, Bobbinet etc. but ions tend to be stopped. It has recently been reported that this can result in a depletion of negative ions and a corresponding increase in positive ions inside the canopy during the course of a night‘s sleep. A good blow-through of the room and canopy each day is probably beneficial for any number of reasons and room ventilation at night may likewise be helpful, though it pays to beware of airborne pollution and the possibility of shifting wind direction while one is asleep.
Ensuring that airborne ions can pass unhindered through a canopy opening allows ion concentrations inside and outside the shielding fabric to normalise to ambient room levels. One way to achieve this without compromising protection entirely is to leave the canopy open at one or both ends or at the sides. About a square foot should suffice but experiment to keep the opening(s) as small as possible - maybe use a hairgrip or clothes peg to lift up the fabric. Whilst this will reduce shielding effectiveness a little, if thick walls or other substantial structures provides some protection, then theirs is possibly the best direction to have open. Hanging a large piece of shielding cloth on a wall opposite may provide some shielding of the opening. Measuring equipment bought or hired can reveal the effectiveness of the shielding and allow suitable adjustment to optimise the configuration. 
Note: Canopy materials may not be effective at shielding against high GigaHertz (8+GHz) satellite radiation, 5G or lower frequency (Long Wave KHz) signals but can still be expected to reduce total (cumulative) EMF exposure .

Alternatives to Wi-Fi CAT-5/6 - Updated

Electric Forester's Structured Cabling 10/100 LAN Primer

( scroll to the end for solutions) 

This post relates to both CAT-5 and later CAT-6 Local Area Networks (LAN) cables.

Category 5 cable is typically made of four unshielded twisted copper pairs. The two wires of each pair are designed to carry equal and opposite signals. Any emissions from one wire are counteracted by equal and opposite emissions from the other in the pair. Screened cable and CAT-6 is used in high security or electrically noisy environments or to protect the electromagnetically hypersensitive. The CAT-5 cable feeds CAT-5 sockets around the building that computers and peripherals simply plug into.
Cables have to be installed by someone who knows what they are doing because tight bends and running next to power cables can for example, reduce data transmission speeds. CAT-5 is a mature and well-tried technology and there are many competent installers. The point about CAT-5 is that it is faster than wireless, more secure and safer because the radio waves stay in the wires and are not broadcast. The CAT-5 sockets are wired via a central 'Patch Panel' to a Local Area Network (LAN) switch which acts like a mini telephone exchange, allowing every socket to be connected to every other. You don't need to get bogged down with the detail as this only really needs to be done upon installation and provided everything is labelled properly and a record kept of the connections, its easily managed by someone competent with paper and pencil.
Each computer and peripheral simply plugs into a socket - can be any one, and then users have interconnectivity between computers, printers, projectors etc. Internet access is via a central router that shares the building's Internet connection between those computers that require it at any given time, making best use of available bandwidth. Internet is provided to the building and central router via telephone cable or fibre-optic 'pipe'. Fibre-optics are much faster (Lasers are used to send the data and each colour can carry 157,000 simultaneous phone calls, effectively making the bandwidth unlimited). If you imagine CAT-5 like the water supply to your taps, a fibre optic 'pipe' is like 4-foot water main, so more than you would ever need. Many people think that wireless networks work all by themselves and they don't need anyone to look after them. School computer budgets (as in commercial settings) have to include hardware, software and support otherwise the investment falls into disrepair and become a waste of money. DLANs, which plug into the mains, send radio frequency signals over building electrical wiring. Mains cabling was never designed for this type of use and signals leak out all over the place and dirty electricity throughout the building will be increased. Speeds may also not be what the manufacturers or users would expect. 
As children grow, their total lifetime exposure will inevitably rise. Daily electrosmog levels continue to rise and come from such sources as mobile phones, their masts, broadcast TV and radio stations, satellites, DECT baby monitors and cordless phones, Xbox 360s, BT-Home Hubs, Sky+HD set-top boxes, microwave ovens, wireless boiler thermostats – the list grows daily. Everyone’s world is now awash with man-made pulsed digital microwave radiation so it makes sense not to add to it further in buildings where particularly children spend considerable time.

As well as computers and shared peripherals, you may want some phones! But the phone company won't put phones over structured cabling, and your landlord won't let the phone company run their own wiring round the building.
