Earthing: Mattress topper, sheet, duvet
Earthing: Mattresses, mattress toppers, cushions, duvets, sheets, pillows... by discharging the body: ES PRAVENT, EARTHING YSHIELD. WARNING: - Earthing does not protect against the impact of electrons emitted by telecommunications devices and electric fields. - Earthing grounds these electrons that impact the body. Attenuation in W can be correlated with attenuation in decibels. There is a logarithmic correspondence scale. However, all metal mesh fabrics will be able to attenuate 99% of high-frequency fields when measured in WATTS (power measurement). But if the measurement scale is in decibels (dB), which is much finer, then the attenuation reading will be much lower! For example, a fabric that attenuates frequencies around 1 GHz by 20 dB will attenuate 99% of the wave power in Watts. However, a fabric attenuating 70 dB at 1 GHz will attenuate 99.99% in Watts. Therefore, the indication of 99% attenuation in Watts is not sufficiently representative of the fabric's attenuation in terms of high frequencies.
