In the modern world electronics are very closely related to our lives. It has become a part of our life now. One cannot imagine his life without electronics.

Electromagnetic radiation is one of the many forces in the universe. Electromagnetic radiation is an accelerated electric charge generated from the associated electric and magnetic fields. It contains electromagnetic waves that propagate at the speed of light through electric and magnetic fields. Electromagnetic waves do not require any medium to travel. In the modern age we depend a lot on technology. So dependent that we cannot think for a moment without some technology. Computers, mobiles, routers, refrigerators, electric lights, etc. have advantages as well as disadvantages. We usually think about benefits. But very few of us are aware of the disadvantages. Basically radiation is radioactivity. It is also known as radiation.

The greatest characteristic of radiation is its ability to travel through matter. In the age of modern information technology almost all of us use mobile phones. Keeping this mobile phone in the pocket or any other place. After taking it out from that place it will be seen that the place of the body or the place where it was kept feels a little hot. The main reason for this is radiation.

Many of us may not notice it. But actually this happens to all of us constantly. If the phone is made with low-quality hardware components then the level of radiation is higher. So it is better to keep the mobile away from the head while sleeping. The more we can distance ourselves from electronic devices then the less harmful effects of electronic devices will be on our body. Radiation is a form of energy that has the ability to travel from one place to another as waves or particles. If this energy is present in our body for a long time or if this radiation stays in the environment where we are then it is harmful to our body. The skin is most vulnerable to such radiation. Non-ionizing radiation from routers increases the risk of skin cancer.

Various laboratory experiments on animals have shown that such radiation has caused heart, reproductive, intellectual problems in animals which are of great concern. So we will always be aware of our health considering good health. Health is the root of all happiness. It is more dangerous as well as harmful in case of small children. The main reason for this is that they are getting older and their bodies are very sensitive. If the development of the body is hindered for any reason due to radiation then it can be very dangerous later on. Radiation is mainly of three types. Non-Ionizing Radiation, Ionizing Radiation, Neutrons. Non-ionizing radiation is the lowest level of radiation. It is generally distinguished from the other two types of radiation ionizing and neutron radiation. Another ionizing and neutron types of radiation strip electrons from atoms or molecules. But non-ionizing radiation cannot do that. But the energy of this radiation can cause those molecules to vibrate and hence generate heat. Most of our everyday electronic devices emit non-ionizing radiation.

Mobile phones use electromagnetic radiation to transmit data. A mobile phone emits the same amount of radiation as a microwave oven. When searching for a WiFi signal, the wave creates an electromagnetic field in the surrounding area that produces radiation. The mechanical arrangement in which the electric field and the magnetic field are at right angles to each other produces radiation called electromagnetic radiation. In an atom the electron always revolves around the nucleus. As a result a magnetic field is created between the nucleus and the electron. Other side the flow of electrons is electricity. So the rotation of the electron creates an electric field. The interaction of these two fields gives rise to electromagnetic radiation. Apart from this radiation is also generated from mobile towers. So staying away from mobile towers as much as possible is beneficial for health. It is better to avoid the use of electric oven, induction cooker, electric kettle etc. as much as possible.

Using a gas stove instead of an electronic cookware for cooking or heating food can protect against many types of radiation. The same happens with routers. Even if the router used in our home or office is made of low-quality components then there is a possibility of radiation. If there is a router around us we will be able to understand this very easily. Then we notice this after a while. The effect of this radiation damage depends largely on the strength of the router's frequency signal (wave). Router or WiFi sends data through electromagnetic radiation. When our WiFi router transmits data, it emits EMF (Electro Magnetic Field) which can be absorbed by the body. It is a type of non-ionizing radiation. Another important factor is how close our body is to a WiFi device. Most of us users now use powerful routers. In that case we should install the router in an open place. If the router is placed in a closed place the amount of radiation emitted can cause serious damage to us.

Modern science has given us a variety of sophisticated electrical appliances to make life easier and faster. Induction cooker to cook food very easily, use of refrigerator to keep cooked food good, use of microwave oven to heat the cold food in the refrigerator. Everything is interrelated at the same time. Meanwhile smartphones, TVs, laptops, computers, WiFi have now become an important part of life.

However the electromagnetic radiation emitted by these daily companion devices is causing serious damage to the body. The same waves that we normally use to heat food in a microwave oven are radiated into a wireless router. WiFi signal passes through the skin and enters the body. The lower part of the laptop generates intense EMF which can have harmful effects on the body if it comes into contact. So avoid using the laptop on our lap or on our feet. Another important matter is that laptop radiation shield should be used. So as not to have harmful effects on the upper body. Old electrical boards, main switches used to control old electrical connections, etc. constantly emit radiation. Also voltage stabilizer/inverter devices used with household appliances such as refrigerators, air conditioners, washing machines, etc. emit an electro-magnetic field three to five feet around. On the other hand electronic signals are used in television cables. Which is later converted into electron beam. If the mobile phone is near the TV set, the phone call actually overlaps the electromagnetic radiation of the mobile phone with the electron beam of the television.

As a result the television's electronic signal changes and the radiation spreads around. The side effects of electromagnetic radiation are extensive. The amount of electromagnetic radiation generated due to the use of additional smartphones, computers, laptops, televisions, microwave ovens etc. results in various types of complex diseases in the body. So it is best to turn off the router, modem and other internet devices before going to sleep.

Apart from this it is also better not to sleep with smartphones, mobiles or other electronic devices next to the head. Headphones or speakers should be used when talking on the smartphone for a long time. It is very important to turn off the various services of the smartphone, such as WiFi, Bluetooth, GPS, Internet connection, etc. after the need.
