The human body repairs damaged cells during sleep. The problem with electric blankets is that they radiate electromagnetic fields that interfere with this process, which can seriously affect your health.
Decades of scientific research has raised concerns that pregnant women who regularly use an electric under or over-blanket have an increased risk of endometrial cancer and miscarriage, and during the first trimester, a four-fold increase in babies being born with cancer. Other studies have shown that long-term use of electric blankets by children can result in a five-fold increase in the risk of leukemia.
So why are the risks not more widely known?
David Carpenter, M.D., Director of the Institute for Health and the Environment at the University at Albany in New York state decided to find out and published his findings in 2019 in a review article. What he discovered was:
Almost all government or independent studies find either a statistically significant association between magnetic field exposure and childhood leukemia, or an elevated risk… while almost all industry-supported studies fail to find any significant or even suggestive association.
In other words, there has been a sustained corporate cover-up of the facts.
The problem with electric blankets
The electromagnetic fields (EMFs) of electrical appliances reduce the further away from them you are. The problem is, you can’t do this with an electric blanket. It’s designed to be in close proximity to your body to keep you warm.
The magnetic field of many types of electric blankets penetrates 6-7 inches (15-18 cm) into the body. I just measured my own body and if I lie on my back, that’s all the way through me at waist level (I’m of normal weight). And most blankets have a voltage transformer attached that radiates even higher levels than the blanket itself.
Using an electric blanket just to warm the bed and then unplugging it at the wall before you get in does solve the problem. However it doesn’t take into account the way the metal wire in an electric blanket can conduct geopathic stress, which can be just as damaging to health as EMFs.
Geopathic stress (GS) refers to energies that radiate up from the earth and are beneficial to some forms of life such as cats, bees and ants, but detrimental to others such as dogs, cows, horses – and humans. If any part of a bed is located over a GS line, the metal wire in an electric blanket will serve to transmit the GS across the entire mattress.
Symptoms of sleeping over GS range from waking up feeling like you need a good night’s sleep to serious illnesses that will not respond to any form of treatment. Some studies in Germany have shown that cancer patients nearly always have their bed over a GS crossing point (where two GS lines cross).
Even if you are able to find a low voltage, low magnetic field electric blanket and are sure you have your bed in a non-GS location, there is still the matter of the toxic fumes that most blankets emit.
The wires of most electric blankets and heating pads are coated in polytetrafluoroethylene, also known as PTFE – the same stuff Teflon pans are coated with. This outgasses a variety of carcinogenic fumes when heated, most notably tetrafluoroethylene, which scientific studies have shown to cause kidney and liver damage.
So what alternatives are there?
My personal favourites are woollen underfleeces, hot water bottles and, best of all, someone to snuggle up to all night long!
