Tingling Sensation
when alone or
when touching
someone else
lying on the
blanket
This “Tingling” feeling is known as an “electric field effect” and is occasionally known to happen across all makes
and brands of electric blankets. It is caused by the current flowing through the element creating an
Electromagnetic Field (EMF). Some people are more susceptible to feeling this EMF tingling sensation than
others. This is no cause for concern and is in no way an electric shock.
All blankets and controllers conform to IEC 62233 “electromagnetic fields of household appliances and similar
apparatus with regard to human exposure” and are proven to be at least 14 times lower in EMF than the
recommended limits in the standard.
