Wi-Fi equipment emits radiofrequency electromagnetic fields (EMF). Other commonly used household products also emit radiofrequency EMF. These products include: cordless phones.
Excessive WiFi exposure is known to be associated with disrupted learning and memory, sleep deprivation, and fatigue related to reduced melatonin secretion and increased norepinephrine secretion at night. However, the use of any screen time is also associated with these changes.
' While the radiation from your router isn't necessarily dangerous, Isabella explains that it is still a source of EMF radiation that could cause restlessness. 'Turning WiFi off overnight will help ensure that you get an uninterrupted night's sleep and wake up feeling refreshed,' she says.
While EMF emissions from different routers vary, for most home WiFi routers, a distance of 40 feet (ideally, or 10 feet at a minimum) will help your body and shouldn't impact your WiFi connection too much.
These guidelines recognize that too much exposure to electromagnetic field (EMF) radiation can harm the human body, particularly at close distances. While maintaining a safe distance from the WiFi router can greatly reduce your exposure to its radiation, keeping the router in your bedroom is not recommendable.
Electromagenetic sensitivity or Wireless allergy can cause headache and fatigue due to heavy use of devices that release electromagnetic radiation.
It isn't harmful at all to sit near a WiFi source, even for extended periods. WiFi, much like other forms of communication such as satellite and cellular networks, uses non-ionizing radiation, which hasn't been found harmful to tissues yet.
Since the Wi-Fi signal goes out in all directions, the best way to make sure that all of the rooms in your house are in range of the signal is to place the router in the most central location possible. Most modern routers have enough range to completely cover a moderately sized home if placed near the center.
Working with a wireless device too close to the router can have a detrimental affect on performance. The signal may be too strong and distorted causing data corruption and retransmissions which will slow down the performance considerably.
I could give a long technical explanation, but essentially it boils down to how the frequency of WiFi doesn't absorb well into human skin. Even if it did, at 4 to 5 feet you would still be safe due to the low power of the WiFi radio. For that frequency there is no minimum distance.
Is it bad to sleep with your phone beside you? Yes, usually speaking, it's not a good idea to sleep with your phone nearby. Sleep quality may suffer if you keep your phone close to your head while trying to slumber because it emits electromagnetic radiation.
The symptoms most commonly experienced include dermatological symptoms (redness, tingling, and burning sensations) as well as neurasthenic and vegetative symptoms (fatigue, tiredness, concentration difficulties, dizziness, nausea, heart palpitation, and digestive disturbances).
To measure the Wi-Fi frequency, you need to use a high-frequency meter such as the HF-B3G and the AF-3500 (which also measures low frequency). Once the measurement is done, it is relatively easy to provide protective measures against the EMF in Wi-Fi.
RF-EMF exposure levels from Wi-Fi
Typical exposure levels indoors range between ~2 V/m at 1m and ~5 V/m at half a meter from the Wi-Fi router. Users of outdoor Wi-Fi networks are usually several metres from the devices. Therefore, exposure levels from Wi-Fi outdoors are typically below 1 V/m.
When in doubt, move your router 5 to 6 feet away from other electronics. Try to position your router so that large metal objects won't come between it and the areas of the house you want coverage. And think about the metal you might not see.
Your Wi-Fi router should be five to six feet from your TV.
As a rule of thumb, place your Wi-Fi router at least five to six feet (1.5 to 1.8 meters) away from your TV and any other devices which could interfere with the signal, such as your microwave.
Don't put your router on the floor. Get your router off the ground at least 5-7 feet if possible. It's kind of like a light bulb; when you turn it on you want it to shine as far as possible, not straight into the ground.
Research clearly shows that radiation from wireless technology affects the autonomic nervous system and increases anxiety and stress. In particular, it can lead to neurotic disturbances by upregulating the sympathetic nervous and downregulating the parasympathetic nervous system (15, 17).
Since wireless networks produce generally lower RF signals than base stations, no adverse health effects are expected from exposure to them.
Note: Turning Wi-Fi off when not in use only eliminates wireless exposures while the WiFi is OFF. However, you will still be exposed when the Wi-Fi is ON. Therefore, be aware you are still getting significant exposure when the Wi-Fi is ON.
The nbn™ connection box and its power supply only use fixed cables. That means they are not designed to nor intended to emit any wireless radiation.
