If you work long hours using a laptop, you may need a laptop radiation shield. Your laptop emits electromagnetic fields or EMFs, and this may be hazardous to your health.
What Are Electromagnetic Fields?
Electromagnetic fields or EMFs are naturally occurring phenomena created by the movement of electrical currents. They are also known as radiation and are a combination of electrical and magnetic fields. Magnetic fields are created by moving currents and electric fields by stationary currents.
These fields are all around us in our natural environment. The Earth, for instance, possesses its own magnetic field, which allows us to use compasses for orientation and navigation. The sun also emits EMF, which is seen as visible light.
Once electricity began to be commonly used, however, we were also exposed to EMF in our homes. Radiation is emitted by sources such as artificial lighting and electric power lines. The waves used to transmit radio and TV signals also emit EMF.
A strong source of radiation is the electrical appliances we use, such as microwave ovens and Wi-Fi routers. Of course, our mobile devices, such as our cellphones and laptops, also emit EMF.
Due to our increased exposure to EMF, concerns have been raised over their potential health effects. In general, however, exposure to low levels of EMF poses minimal risks to health.
But devices that are in close proximity to the users may pose greater health hazards. One particular area of concern is the use of laptops since there are known to be a strong source of EMF.
EMFs and Laptop Radiation
A lot of people place their laptops on their lap when they are using them because they find it more convenient. They may also use their laptops on the go, where there are no tables to place them on. But this is a hazardous practice since it directly exposes your body to potentially harmful radiation.
Laptops emit various types of radiation, including:
• 400 THz to 800 THz. This type of EMF is in the form of visible light that the laptop screen emits so you can read what is on the monitor.
• 10 THz to 100 THz. This type of EMF is emitted due to the temperature generated by the laptop.
• 5 GHz. This EMF is generated by the radio waves that the laptop’s Wi-Fi antenna emits when it is connecting to a wireless network.
• 2.4 GHz. These are radio waves emitted when the Bluetooth antenna connects to peripherals such as a Bluetooth speaker or wireless mouse.
In addition, laptops also emit some low-frequency EMF due to the inevitable leakage resulting from the electronic circuits. The radiation emitted by laptops is generally too weak to cause adverse health effects.
However, if you place the laptop on your lap, it increases your exposure because it is in direct proximity to your body.
EMF Radiation Health Risks:
• Male reproductive health. Studies have shown that exposure of human sperm to radio waves generated by the Wi-Fi antenna may decrease their motility as well as increasing the fragmentation of their DNA.
• Increased cancer risk. Research conducted by the International Agency for Research on Cancer (IARC) of the World Health Organization indicated the possibility that EMF may be carcinogenic. Some studies reviewed by the IARC show that there could be a link between cancer and EMFs.
• Pregnancy issues. Researchers have found that there may be a correlation between exposure to EMF and increased risk of miscarriage in pregnant women. A study found that 75% of women who had “high exposure” to radiation were nearly three times at risk of miscarrying compared with those who had “low exposure”.
There are also other minor risks associated with the use of laptops on laps. For instance, hunching over a laptop could result in back and neck pain over time.
Using a laptop just before bedtime can also result in poor sleep. The artificial light emitted by the monitor may hamper the release of melatonin, a chemical that helps you sleep.
The most obvious solution to avoid these issues is to avoid placing the laptop on your lap. The Federal Communications Commission (FCC) mandates that the distance between a transmitter and the user’s body should be at least 20 cm or eight inches.
You can achieve this safe distance by placing the laptop on a table, or a standing desk, in order to limit your radiation exposure. If this is not possible, you can place a pillow or phone book between your lap and the laptop, which will provide you with some protection while preventing possible singeing due to the heat emitted by the device.
Another thing you can do to limit exposure to EMF is to avoid using Wi-Fi as much as possible. Turn off the Wi-Fi on your laptop when you do not need to be connected to the Internet. Or you can connect to the web using Ethernet wiring if available.
But if you are genuinely concerned about being exposed to radiation, you can get EMF protection laptop shields. These will help you avoid the risks associated with the EMF emitted by your laptop.
Laptop Radiation Shield: Does It Work?
This is a natural question for you to ask. After all, there are also many people who feel that the alleged risks of EMF exposure are exaggerated.
However, if you are one of those people who may be vulnerable to these health risks, then why not invest in protection? After all, laptop shields do not cost that much money compared with the possibility of having to incur medical costs.
The shields may also make using your laptop more comfortable since they will not only insulate your body from the heat it generates, they will also elevate the laptop slightly so you don’t have to hunch forward when you are typing or reading.
You can find many types of laptop shields you can buy from online retailers such as Amazon. The best way to choose which one works best for you is to read the description, and then look at the reviews.
One tip when reading the customer reviews: focus on the three and four-star reviews. The reason is that these reviews will give you a more balanced view of the product.
Three-star reviews are more likely to give you some drawbacks in addition to the benefits of the laptop shield, so you can make a more informed decision as to which to buy. Four-star reviews may also mention some things they did not like about the product.
There are also manufacturers that sell some of the best laptop shields and other products to protect you and your family. You can check these websites to quickly find out what products are available and the features that they have.
One of the best we have found is Shield Your Body. They provide education, consulting, and great products with lifetime guarantees!
They also provide you with their own breakdown of the pros and cons of each product. This makes it easier for you to find the product that best meets your needs.
Whether or not you need a laptop shield is a personal decision. But if you really cannot avoid placing the laptop close to your body while you are using it, then why not be safe? A laptop radiation shield is an affordable investment in your health. Just make sure you choose the one that will provide you with the most protection.
