Some of you who use the internet all the time might not understand why you would want to block WiFi signals, let alone how to do it in a room.
Well, when it comes to the Internet, most people agree that the better the networks are around the house, the better it is for everyone to surf. But what about the effects of WiFi and other devices in your home that give off EMF on your health?
There are also other reasons why you might want to block WiFi access to a certain room. For instance, if you don’t want your kids to spend too much time on the internet, you could block access to the internet in their room in a number of ways. Your own reasons may be why you want to block WiFi signals in a room, but we have a few ways you could try.
Having children makes the risk of electromagnetic radiation even more important to think about. It can build up and make you and everyone around you feel bad.
What is Electromagnetic Radiation?
Electromagnetic radiation, also called EM radiation, EMR, or EM waves, is what happens when an electromagnetic field, or EMF, sends out waves. These waves move through space and our environment, carrying radiant energy with them. The electromagnetic spectrum includes radio waves, microwaves, infrared, UV, X-rays, and gamma rays.
Even though these EMF radiations are safe in small amounts, they can be very dangerous when they add up. For example, your home is probably full of EM radiation if you have a lot of high-powered electronics. EMF is made when electrical charges move, like when you use a cell phone or a high-power appliance. EMF can build up in your environment when you use a cell phone or a high-power appliance.
Now, they might not be dangerous in small amounts, but as they add up, the problems with EMF become clear. The main danger of EMF exposure is that it can cause a number of problems, such as fatigue and stress, and can even lead to serious illness.
What exactly is a WiFi Signal?
Before we can figure out how to block WiFi signals in a room, we need to know what they are and how they work. WiFi routers, which send out WiFi signals that other devices in your home can pick up, are actually wireless communication devices. The electromagnetic spectrum includes the waves that a router sends out. Anything that gets in the way of these waves or makes them interfere with each other will weaken the signal.
A WiFi signal is strong and can travel a long way before it starts to weaken. There are many materials and situations that can make a WiFi signal weaker, and there are also many ways to make it stronger again. For instance, WiFi signals from your neighbor’s router can also make your home’s WiFi less effective. In these situations, it is important to make sure there is no interference from outside sources. Using the same methods you would use to stop signals from getting into a room, you might be able to stop all signals from the outside as well.
But experts say that when it comes to your home, you shouldn’t have free WiFi signals floating around and reaching every room. You should have plans in place so that WiFi signals can’t get into your child’s room or your own. Your work room, study, or even living room could have WiFi, but make sure WiFi signals can’t reach where you sleep.
WiFi signals pose many problems, so why should a room be blocked from WiFi signals?
As was already said, EMF radiation also includes WiFi signals. This means you should definitely keep WiFi routers, extenders, and even the slightest WiFi signal out of your kids’ bedrooms and, if possible, out of your own as well.
But what are the actual problems with WiFi signals? And why do we need to know how to stop WiFi from working in a room?
1. Microwave energy in large amounts
People whose homes have big WiFi routers are often exposed to a lot of microwave energy. This could hurt your mood, which could then make it hard for you to do things.
2. There are many health concerns
People who say they feel dizzy, lightheaded, sick to their stomachs, nervous without any cause, or have trouble falling asleep often have too much EMF radiation from their home appliances, especially WiFi routers and extenders.
3. EMF radiation
The main sources of electromagnetic radiation are Bluetooth devices and WiFi routers. Low frequency radiation is harmless at first and in small amounts, but as it builds up, the health risks become clearer and clearer.
4. Insomnia
High EMF levels caused by WiFi signals can make it hard to sleep. If you have trouble sleeping at night for no obvious reason, you might be getting too much EMF radiation. A 2007 study found that people who slept with their phones close by and WiFi turned on had a much harder time falling asleep
5. Poor mental functioning
Researchers also found that when young adults were exposed to high levels of EMF radiation, their brains didn’t work as well as they should. It is very important to block WiFi signals in the room where your kids sleep.
6. Plant growth
If you think your indoor plants aren’t growing well, it could be because there are too many EMFs in your home. Several studies have found that plants, in particular, soak up a lot of the radiation in your home. It might be good for you, but if you really want to make a change, you might want to turn down the WiFi signals in rooms where they aren’t needed.
How to check the EMF in a room?
This is easy to do and a must if you want to make your house safe for kids. You should do everything you can to keep your family from getting too much EMF, which can cause a lot of problems.
If you are determined to get rid of EMF from your home and make it a safe place for your family to live, you could easily buy an EMF reader. You can find one on any online store for a price that isn’t too high.
Just put your EMF reader in the room where you want to check the radiation level and turn it on. It tells you what the reading is in W/cm2 or microwatts/cm2.
Once you have the readings, you can use them to check for safety levels in the following.
- For houses, the average level is – 0.0001 to 0.5 μW/cm2
- Precaution Level for the General Public – 0.001 μW/cm2
- Level recommended by the FCC for public use – 1000 μW/cm2
- EMF Level for People Hypersensitive – 0.001 μW/cm2 or lower
How to Block WiFi Signals in a Room?
There are many ways to stop WiFi signals from getting into a certain room. Just to be clear, signal jammers should not be used. Most states think that signal jammers are against the law, and if you use one, it could cause you a lot of trouble.
There are several ways to completely block WiFi signals from getting into a certain room. Here’s how to stop WiFi from working in a room.
1. Cover with Mylar blankets
Putting Mylar or space blankets on the walls of a room is a sure way to stop WiFi signals from getting in. Space blankets, which can also be used as first-aid blankets, are thin blankets made of heat-reflective plastic sheeting. When used to control temperature, they are very good at keeping EMF from getting into a room.
2. Aluminium
You could line the walls of a room with Mylar blankets to stop EMFs from getting in, or you could use a sheet of aluminium foil to do the same thing. Just make sure the aluminium is on the outside to get the most out of it. This is a much easier way to do it, since sheets and foils of aluminium are easy to find and don’t cost too much.
3. Wi-Fi blocker paint
Well, yes, they do have paint that blocks WiFi. You could try to get this special paint, which is very good at keeping EMFs from getting into a house. It can be hard to find this paint, and the good kind doesn’t come cheap.
4. Electromagnetic Field Adapters
Online, you can find EMF adapters in many different formats. Some of them plug into an outlet, while others are just stickers that pick up the free EMF that floats around your house every day. You might want something like the SmartDot. They are magnetic discs that react with radiation to stop it quickly. Attaching one to your larger appliances, like your refrigerator or air conditioner, is the best way to stop the radiation from spreading. Some adapters even work by sending resonant signals throughout the room to completely get rid of any radiation that might be there.
Listed below are the best ways to block WiFi signals in a room, which will result in a healthier lifestyle.
Other Methods to Block WiFi Signals to a Room
These are the best and most effective ways to stop WiFi signals from getting into a room. There are also a lot of other things you could try, but they aren’t very good. Instead, they involve things you could do at home without any help or special tools.
1. Router positioning
This one is pretty easy. Since you know that WiFi signals can only reach that far, you might be able to move the router so that the signals don’t reach a certain room. It might not be easy to do this, and it might take some knowledge or trial and error, but you can be sure that the signals will weaken before they reach a certain room.
2. Decorations
Even though it’s not a must and isn’t even recommended, you could wrap tin foil around the router and point it toward the area of the room where you don’t want signals to reach. It’s an easy way to do things, but it might not work as well as you’d like. Even so, it still works. You could also use blocking cloth instead of tin foil. Faraday fabrics are one type of material that can block EMF and WiFi signals from getting into a room. You can get them at an upscale hardware store, but be aware that they are not cheap.
Interference with WiFi signals by other materials
You can also easily block WiFi signals with a lot of different things. Aluminum isn’t the only thing that can block WiFi signals to a room. There are a lot of other things that can do the same thing.
- Metal: Most metals are the best at blocking signals. Since it lets electricity flow through it, radio waves just go right through it. WiFi signals can be stopped with thick sheets of metal.
- Concrete: Yes, concrete blocks are effective in blocking WiFi signals in most cases, if not all of them.
- Plaster: Signals can’t get from one place to another because of the coatings on your walls. If the plaster is thick enough, you can block all WiFi signals from coming into a room.
- Glass: In the same way that glass reflects light, it also reflects electromagnetic waves.
- Other electronic devices: So, yes. If you have more than one device at home that uses the same frequency, the signals from each one might cancel each other out. In general, WiFi runs mostly on the 2.4 GHz band. If you can find a device that sends out a signal with the same frequency, you can effectively block the signal and make it go away.
- Water: Water also has a big effect on how strong signals are. Because of this, you can never get a good signal in an aquarium.
- Appliances: As was already said, most appliances send out EMF signals and give off radiation. They are also mostly made of metal, which makes them even worse. It is known that appliances can pick up WiFi router signals and block their effects.
Conclusion
You might want to stop WiFi signals from getting into a certain room for your own reasons, but there are many ways to do that. Some of the ways are easy, but others can cost a lot or require you to start while your house is being built. The best time to signal-proof a room is when it is being built. As a parent, it’s important that you make sure your kids and family don’t have to deal with the effects of EMF radiation.
