The "No-Brainers" for Physical and Mental Health:
"The Body Electric"
CELL PHONE NetworksNetworks with higher carrier frequencies have faster data transmission speeds (i.e. bandwidth). Higher bandwith enables faster file downloads / uploads and faster video streaming. "G"enerations of wireless networks have progressed from 3G at speeds of 20-50 Mbps, to 4G (up to 10x faster than 3G), and now 5G with speeds categorized into low-band (<1Ghz), mid-band (1-6 GHz) and high-band (>24 GHz), 10-100 times faster than 4G. Although higher frequencies are faster than lower frequencies, they can not can not travel as far. This is because higher frequencies cannot penetrate solid objects, such as walls and floors as well as lower frequencies. Wifi - A wireless local area network (WLAN)Wifi applications most commonly use carrier frequencies, which do not penetrate very far into human tissue:
A digital pulsed radio-frequency (which includes microwave frequencies) EMF of 10-250Hz can penetrate walls, ceilings, floors and HUMANS. Wifi routers for wireless internet typically transmit a signal 10 times per second, 24 hours per day, even when they are not being used; |
The World Health Organization (WHO) has classified radiofrequency electromagnetic field exposure (includes Wi-Fi radiation) as a Class 2B carcinogen. i.e. it is possibly carcinogenic to humans.
Independent research studies point to several adverse biological effects of wi-fi radiation:
Use of laptop computers connected to internet through Wi-Fi decreases human sperm motility and increases sperm DNA fragmentation. Two equal-sized portions of sperm taken from 29 donors. One portion was exposed to a wireless internet-connected laptop for 4 hours, the other portion was the control. Results showed a significant decrease in sperm motility, and an increase in DNA fragmentation to exposed portion. Levels of dead sperm were unaffected. Avendaño C. et al., 2012, Link
2.4GHz Wi-Fi signal reduces brain's signal amplitude (i.e. energy / cortical excitability) in alpha and beta range frequencies in women (but not in men). 15 men and 15 women performed a short memory test both with and wthout exposure to a 2.4GHz (typical wifi frequency) signal. Amplitude within EEG (Electroencephalogram: records electrical activity in brain) alpha, beta, delta and theta frequency ranges were calculated (using Fourier transforms) from recordings of 30 differently positioned scalp electrodes. Alpha and beta energies in two brain areas (right-anterior and occipital) were significantly lower in women, but interestingly not in men. Delta and theta frequency readings showed no noticeable effect on alpha and beta rhythm amplitudes in either gender. Maganioti et al, 2010
Another similar test focused on neural activity affecting attentionand working memory areas of the brain, finding that wifi exposure reduced amplitudes of certain brain areas in both men women, and just men for other areas. Papageorgiou C. C. et al., 2011, Link
Ethernet cable conecting your modem / router to your computer may be emitting radiation. Ensure you are using a Cat 6a SSTP (screened shielded twisted pair) ethernet cable, which shields any emission.
Replace your wireless keyboard, mouse, printer, scanner etc with USB wired connections.
Radiation field strength drops off with distance. Putting any electrical device a few extra feet away from you significantly reduces radiation exposure. Probably why you don't hear much about a digital TV set causing health problems.
Deactivate router wifi and wifi on all devices when not in use (E.g. cell phone, ipad, laptops etc). In particular, there is usually no reason to have wifi on at night.
JRS Eco 100 Low EMF WiFi Router Developed by a father (an electronics engineer) to protect children at his son's school from wifi radiation. Provides low EMF function at 1 pulse / second when router is on stand-by, compared to usual 10 pulses / second. This router throughput data speed and network stability are the same as regular wifi, but with less radiation; works with both DSL and cable inernet.
