It could be confusing to some of you prodigal internet users as to why you would block WiFi signals, let alone how to block WiFi signals in a room.
Well, when it comes to the internet, it is widely considered that the better networks you have around the house, the better it is for everyone surfing. But what about the health effects of WiFi and other EMF radiating devices around your house?
There are also other factors that might be at play as to why you wish to block WiFi to a particular room. For example, if you do not wish your children to spend excessive amounts of time on the internet, you could potentially block the internet to their room using a variety of methods. Your reasons might be your own, but we have multiple methods you could potentially use to block WiFi signals in a room.
If you have children especially, the risk of electromagnetic radiation should not be taken lightly. It can build up and heavily affect you and everyone around.
What is Electromagnetic Radiation?
Electromagnetic Radiation, or EM Radiation, or EMR, refers to the waves resulting from an electromagnetic field, or an EMF. These waves propagate through space and our surroundings carrying radiant energy. Radio waves, microwaves, infrared, UV, X-rays, and gamma rays, all form part of the electromagnetic spectrum.
These EMF radiations though harmless in minor quantities, can get especially dangerous when they collect. For example, if your home has a lot of high-power electronics, chances are, you house is infested with EM radiation. EMF is produced by moving electrical charges and the use of mobile phones and high-power appliances can cause a build-up of EMF in your surroundings.
Now, they might not be harmful in low quantities, but as they build-up the issues regarding EMF get clear. The underlying threat of EMF exposure includes a variety of problems, including fatigue, excessive stress, and can even result in severe sickness.
What exactly is a WiFi Signal?
Before understanding how to block WiFi signals in a room, we must understand what WiFi signals are and what they are made of. WiFi routers that give rise to WiFi signals to be picked up by devices around your house, are actually communication devices that function wirelessly. The waves a router sends out are part of the electromagnetic spectrum. Anything that results in the blockage of these waves or causes interference will cause the signal to weaken.
A WiFi signal is strong and carrys for quite the distance before starting to dwindle. There are multiple materials and ways a WiFi signal might weaken, and multiple ways you can boost it back up. For example, WiFi signals from your neighbours router can also effectively reduce the effectiveness of the WiFi in your home. In such cases, it is necessary to ensure no amount of interference is received from outside sources. Using the same methods you would to block signals to reaching a room, you could potentially block all signals from outside as well.
However, when it comes to the home environment, experts suggest you should not have free WiFi signals floating throughout your home and reaching every room. You should have contingencies in place that do not allow WiFi signals to reach your child’s bedroom, or even yours. A work room, or study, or even your living room could have active WiFi, but make sure where you sleep, WiFi signals cannot penetrate.
What are the Problems with WiFi Signals and why should you Block WiFi Signals in a Room?
As mentioned, WiFi signals are also a part of the EMF radiation. This means you should totally be keeping any WiFi routers or extenders, even a hint of WiFi signals out of your children’s bedrooms, and of your own if possible as well.
What exactly are the problems with WiFi signals however? And why are we learning how to block WiFi signals in a room?
1. Large amounts of microwave energy
For folks who have large WiFi routers in their homes are often subjected to large amounts of microwave energy. This can have adverse effects on your mood and in turn, your functioning might also be affected.
2. Plenty health related issues
When it comes to people reporting dizziness, lightheadedness, intense feeling of nausea, nervousness without any stimulus, and even trouble falling asleep, the reason has often been found to be excessive EMF radiation due to the appliances at home, mainly WiFi routers and extenders.
3. EMF radiation
Bluetooth devices and WiFi routers are the primary purveyors of electromagnetic radiation. They give off a low frequency radiation which is harmless at first and in low quantities, however, as they build-up, the health risks get more and more obvious.
A side effect of high levels of EMF due to WiFi signals is insomnia. If you have been having trouble sleeping at night without any actual stimulus, you might be taking in high levels of EMF radiation. A study conducted in 2007 concluded that people who slept with their phones close to them with WiFi activated had a much harder time going off to sleep.
5. Low brain functions
Researchers also found that exposure to high levels of EMF radiation affected the proper brain functioning in younger adults. It is highly advised to block WiFi signals in a room your children sleep in.
6. Plant growth
If you feel your indoor plants are having a tough time growing, the cause might just be excessive EMF inside your house. There are multiple studies done which concluded that plants especially absorb a whole lot of radiation inside your house. It might be a good thing for you, but if you really wish to make a change, you might want to dull down WiFi signals in rooms they are not necessary.
How to check the EMF in a room?
This is a relatively easy thing to do, and also a must if you wish to child proof your house. By all means, you should be making sure your family does not get excess EMF in their system which can cause a variety of issues.
For those adamant about relieving your house of EMF and providing your family with a safe, livable environment, you could easily invest in an EMF reader. You can find one on any eCommerce website for quite the affordable price.
Simply take your EMF reader into the room you wish to check the amount of radiation in, and start the device up. It gives you reading in the form of μW/cm2 or microwatts/cm2.
Once you have the readings, you can check the following for safety levels.
Average level for Homes – 0.0001 to 0.5 μW/cm2
General Public Level of Precaution – 0.001 μW/cm2
FCC Recommended Level for Public – 1000 μW/cm2
Level for People Hypersensitive to EMF – 0.001 μW/cm2 or lower
How to Block WiFi Signals in a Room?
There are multiple methods you could use to block WiFi signals in a particular room. Just to be clear in the beginning, do not use signal jammers. Signal jammers are considered illegal in most states and could potentially cause a lot of issues for you if you make use of them.
To properly and completely block WiFi signals to a particular room, you can use multiple methods. Here is how to block WiFi signals in a room.
1. Use Mylar Blankets
Lining the walls of a room with Mylar, or space blankets is a sure way to avoid getting any WiFi signals into a room. Space blankets, or first-aid blankets are low-weight blankets made from heat-reflective, plastic sheeting. Used as thermal control, they are very effective at blocking any EMF from reaching a room.
Just as you would line mylar blankets on the wall of a room to avoid any EMFs getting in, you could similarly use a sheet of aluminium foil to block the radiation as well. Simply make sure the Aluminium is facing outwards for peak efficiency. This is a much easier method since aluminium sheets and foils are relatively easy to find and quite affordable.
3. WiFi blocking paint
Well, yes, they have WiFi blocking paint. You could try and get your hands on this speciality paint which is highly effective at blocking any EMFs from entering a house. This paint can be hard to come by and the high-quality kind is not cheap at all.
4. EMF adapters
There are multiple formats of EMF adapters available online. Some of them might plug into an electrical outlet, while others are simply stick-ons that absorb free EMF that floats around your house on a daily basis. Something like the SmartDot and the RadiationStopper Pro might be the thing for you. They are magnetic discs that interact with radiation and quickly quell it down. It is best to attach one to the bigger appliances in your house, like refrigerators and air conditioners, so that the radiation is killed before it has time to spread. Some adapters even work by sending resonant signals throughout the room to completely remove any radiation that might be present.
Here were the best possible ways to block WiFi signals in a room which can lead to a healthier lifestyle.
Other Methods to Block WiFI Signals to a Room
The methods mentioned above are the best and most effective ways to block WiFi signals in a room. Other methods include a variety of things you could try, but they are not that effective, but require materials or methods you could do at home without any help or need for a speciality item.
1. Positioning of the router
This one is simple enough. Since you know that WiFi signals can only travel that far, you could potentially change the positioning of the router so that the signals simply do not reach a particular room. This might not be easy and would take either know-how or trial and error, but it is guaranteed that the signals would dull down before they have the chance to reach a certain room.
Though it is not absolute or even recommended, you could place tin foil around the router towards the general area of the room you want blocked from signals. It is an easy to do method, but really might not work as efficiently as you might hope. Still works though. You could use blocking fabric in place of the tin foil as well. Faraday fabrics are one such material that is used to effectively block any EMF or WiFi signals trying to get into a room. You can pick them up at a high-end hardware store, but beware, they do not come cheap.
Other Materials that Interfere with WiFi signals
There are also.plenty of materials that you can easily use to block WiFi signals. Similar to aluminium, there are plenty more elements that can help you block WiFi signals to a room.
- Metal: Most metals are the ultimate signal blockers. Since it is a conductor of electricity, radio waves are simply absorbed by them. Thick metal sheets are perfect to block any WiFi signals.
- Concrete: Yes, simply thick concrete blocks are capable of blocking most of, if not all of the WiFi signals.
- Plaster: The coatings on your walls also disrupt the flow of signals from one place to another. A thick enough plaster will allow you to completely block out WiFi signals to a room.
- Glass: Much like glass reflects light, it is also responsible for reflecting electromagnetic waves.
- Other electronic devices: Well, yes. If you have multiple devices at home that are running at the same frequency, both of them might be able to cancel out the signals from each other. Basically, WiFi mostly runs on the 2.4 GHz band. If you can find a device that emits a similar frequency, you can effectively interfere with the signal and dull it down to zero.
- Water: Water also heavily affects the potency of signals. This is the reason you never get good signals in an aquarium.
- Appliances: As mentioned above, most appliances emit EMF signals and radiation, not to mention they are mostly made out of metal. Appliances are known to absorb signals from WiFi router effectively disabling its effects.
When it comes to blocking WiFi signals to a specific room, the reasons might be your own, but there are plenty of ways you can achieve that. Some of the methods are easy, but some can cost you a lot and you also might have to start while you are building your house. Signal proofing a room is best done while it is being built. It is crucial for you as a parent to make sure you children and your family in fact does not have to suffer from the consequences of EMF radiation.
