Everywhere you look, there are computers, laptops, cell phones, tablets and WiFi networks. These sources are in our homes, schools, workplaces, cafés, and public areas. The list goes on and on. And, they are only growing in use and popularity.
As of January 2015:
- 91% of internet users own a PC/Laptop
- 80% of internet users own a smartphone
- 47% of internet users own a tablet computer
Electronic devices are not only growing in popularity, they are growing in usage. According to a Nielsen survey, the average American spends 11+ hours a day with electronic media. A huge percentage of our lifetime is spent watching TV or listening to the radio. With the average amount of sleep a normal person must have around 7.5-9 hours, we spend approximately 67% of our waking hours wired.
Despite the amount of time they spend using them, the average person knows surprisingly little about electronic devices, how they work, or if there are any potential downsides to their use. By virtue of the way they work, all electronic devices emit forms of Electromagnetic Radiation (EMFs). With people using these devices close to their bodies on a regular basis, many people are becoming concerned about constant exposure to EMFs.
The fact is EMF radiation can have a profound impact on the human body. Some types of radiation can adversely influence the biology of the cells, modifying their behavior. Radiation known as “thermal radiation” has the ability to heat up our cells. Finally, our bodies use electricity within to properly function and external signals from electronic devices can interrupt or confuse living tissue. That’s why it is important to educate yourself about electronic device emissions with up-to-date information and make informed decisions on how we use the devices that surround us every day.
Scientists are conducting long-term studies to improve our knowledge, but one thing is becoming more clear. EMF radiation can be a potential risk to our well being. In fact, the World Health Organization established an International Electromagnetic Fields Project in 1996 to assess the scientific evidence for possible adverse health effects from EMFs and this work continues to this day.
Ionizing Radiation vs. Non-Ionizing Radiation
Radiation is a form of energy transmission. When energy moves, it may travel as a particle or a wave. All radiation can be characterized by the Electromagnetic Radiation Spectrum, a chart which depicts all types of energy movement as a wave. Generally speaking, there are two broad categories of Electromagnetic Radiation (EMF). “Non-ionizing radiation” and “ionizing radiation.”
Electromagnetic Radiation can carry low or high energy. If the radiation has a low wavelength, it has high energy. If it has a high wavelength, it has low energy. This is because energy and wavelength have an inverse relationship.
Ionizing radiation is the stuff that is considered high energy. It is known to cause DNA damage, and even a short burst of high energy radiation can permanently damage a cell. An extreme example of ionizing radiation would be that of an atomic bomb.
Non-ionizing radiation is low energy and some argue that it is safe because for that reason. However, health concerns such as cell damage, are not immediately seen with non-ionizing radiation exposure but are still very much a health danger.
A growing body of scientists believe that exposure to non-ionizing radiation over prolonged periods, such as years, may cause serious health issues and current scientific studies are substantiating their concerns. As an analogy, anyone who has ever seen the Grand Canyon can tell you, exposure to a small force (in this case, a river) over a long period of time can cause great changes.
An overwhelming number of studies have been conducted on Electromagnetic Radiation that show there can be many risks to our health. Nonetheless, because many electronic devices we use everyday like laptops, tablets cell phones were only recently invented, long-term exposure studies have not been completed. Scientific studies can take up to 20 years or more to establish definitive conclusions. While research is still ongoing, we fill our lives with more and more electronic devices. Wake up and you see your alarm clock. Go to work and you pass traffic lights while driving your hybrid car. You sit at your desk, answer your phone, turn on your computer, and all the while basking in the soft glow of Electromagnetic Radiation exposure. For years, this goes on. What happens in the future?
