emf blanket

Electromagnetic frequency (EMF) blankets are versatile shielding that can be used in a variety of applications to block radiofrequency radiation. They can cover you while you sleep, can be placed on your lap while using your laptop or tablet, and can also be used to protect children from EMF exposure.

Sources of EMF in your environment are varied and include WiFi routers (both for your computers and your smart television), Bluetooth devices, cellular phones, and other radio devices. Outside your home, EMF sources include microwave emitters, radio transmitters, television transmitters, and cellular communications towers.

Beyond these more obvious sources of EMF, microelectronics and faulty wiring in your home are also sources of EMF radiation. Some of these sources of EMF can be blocked with appropriate shielding materials to reduce your overall exposure.

EMF exposure is presently an underappreciated health issue which will only become apparent over time since much of the technology we are talking about here is somewhat new. At this time in history, it is a fact that human beings have never been exposed to radiofrequency energies at the levels or breadth of bandwidth currently in the environment.

Since it is a new phenomenon, we really have no clue as to what the long-term effects on human health will ultimately look like. Precautions taken now may save you from the negative effects of constant EMF exposure in the future.

Besides putting shielding around all these various devices in your home, personal protection garments and blankets are also extremely useful additions to the strategy of reducing your EMF exposure. Before we launch into a review of our picks for the best EMF blanket materials and products, let us discuss what exactly is EMF radiation.

EMF Radiation

Electromagnetic radiation describes energy emissions in the electromagnetic spectrum. The electromagnetic spectrum spans all the energies which exist in the universe.

On one end of the spectrum, you have very low-frequency waves in and below the radio bands. Slightly higher frequency waves are in the infrared band, just beyond the range of visible light for humans, and are what we characterize as heat from most heat sources.

Visible light sits somewhere in the middle of the spectrum, progressing through higher frequency energies outside the visible range in the ultraviolet, microwave, x-ray, and gamma-ray bands.

All of these sources of energy consist of emitted photons, just like the light you are seeing right now. They differ only in their frequency.

Although described as radiation, it is not what most people think of as radiation which is ionizing radiation.

Ionizing radiation, which is part of the electromagnetic spectrum, typically comes from radioactive material sources and consists of high energies and high-frequency waves. These energies are termed ionizing because they have the ability to break chemical bonds and ionize or transform atoms to a charged state by stripping away or donating electrons.

What we term EMF radiation, although it can also be dangerous, is non-ionizing radiation in that it cannot break chemical bonds under normal emission energies. This is not to say that high-intensity radio waves cannot cause chemical changes, but those would only be experienced if you were standing on top of a radio tower next to the transmitter while it is on.

EMF energies consist of two main components. They consist of electric fields, which result from a difference in voltage (potential) between two sources of charge, just like in an electrical circuit.

The larger the difference between the two sources of charge, the greater the electric field.

EMF sources also consist of magnetic fields. These are produced from the flow of current, which is a flow of positive charge, between two sources of charge (one positive and one negative).

The stronger the flow of current, the stronger the magnetic field. Electromagnetic fields incorporate both of these features, electric fields, and magnetic fields, and can be transmitted through materials or through the air, depending upon the type and intensity of the field.

We describe the features of electromagnetic fields in several ways, by frequency (how often energy pulses are emitted) and by wavelength (the distance between pulses of energy).
