Whenever we use our trusty laptops, tablets, or smartphones, it never really occurs to us that these devices emit radiation or electromagnetic fields (EMFs). It's not a surprise since most of us have been born with televisions, computers, microwave ovens, and other electronic gadgets in our homes. Most of us can't even function efficiently without them. But a lot of people are raising issues about how EMF could affect health. Does it really? If so, how do we protect ourselves from radiation? We can't just chuck our iPhones out the window because someone tells us that these are hurting our brain cells, right?
About EMI and EMF
EMI or Electromagnetic Interference
EMI refers to factors that affect how a gadget functions. Here is an example. A unit with high EMI can cause the images on your television to go all jerky. It might also affect your radio and personal computer. All in all, because high EMI can influence the performance of electronic tools, it is rudimentary for units to be thoroughly tested first before these are mass produced. This enables EMI regulating bodies to monitor if the products manufactured and then sold in the world market are up to par.
EMF or Electromagnetic Field
Everything that runs on electricity creates an electromagnetic field that produces very low levels of radiation. Even if a device is turned off, it can still generate small amounts of radiation. Sources include but are not limited to the following: television, computer, fluorescent lamp, microwave oven, clothes washer, and hair dryer. The EPA (Environmental Protection Agency) provides information about the danger zones. There are specifications about how far you should be from units in order to remain relatively safe.
Mission: Family Protection
Of course, you have to do your part in protecting yourself and your loved ones from EMFs. Although there is no definitive evidence yet about whether or not EMF can drastically harm health, some claim that overexposure can result in headaches, sleeplessness, and even cancer. So, how do you lower the risk?
1. Buy new electronic appliances.
The older your television is, the less efficient it is. This goes the same for all your kitchen equipment and other devices. New gadgets are more efficient and they should have passed quality standards, which are definitely more stringent these days.
2. Check the EPA website to determine the “danger zones.”
You are in the danger zone if you're just 4 to 20 inches away from your computer. Lower your risk by staying at least two to five feet from it. This is what the EPA recommends. There are more itemized details regarding danger zones on their website.
3. Be quick.
If you are regularly using, say, your hair dryer, then you should use it quickly to reduce the amount of time that you're exposing yourself to radiation. This goes the same for all the gadgets found in your home.
4. Don't sleep with your cell phones.
Most of us like to keep our smartphones and tablets nearby. But if you want to protect yourself from radiation, keep all devices at least six feet from your bed.
