Over the past decade, the use of cellular phones has grown exponentially. Indeed, recent estimates place the international use of mobile phones at well over 100 million people. As the use of cell phones becomes more commonplace, a growing number of researchers are beginning to explore the consequences of intense, long-term exposure to cell phone radiation.

As a culture, we are inseparable from our phones. We use them for work, errands, and all manner of personal communication, and quite frankly, we would be lost without them. In a short period of time, cell phones have become integral to our daily functioning. These days, you'd be hard-pressed to find many people without one.

Although mobile phones have ushered in a new era of ease and accessibility, they have also brought their own set of hazards. Increasingly state and federal legislation is beginning to tackle the issue of ensuring safe cell phone use while driving. A somewhat more complex issue, however, pertains to the health hazards that may be associated with cell phone use

Understanding Cell Phone Radiation

One of the primary health concerns with mobile phone use is the impact of radiation. By definition, a cell phone must release miniscule amounts of radiation to pick up the radio waves by which it operates. This means that each time you place a cell phone near your head, you are increasing your proximity to these emissions.

It is unclear whether cell phone radiation engenders adverse health outcomes; however, many people point to research trends indicating a substantial increase in the rates of brain cancer over the past two decades. Although this increase is likely due to many different factors (including improved diagnostic technology), many people fear that cell phone radiation may be contributing to the rise.

Based on preliminary research, the FDA concluded that cellular phones do not emit enough radiation to pose serious health risks. At the same time, they acknowledged that some studies have produced mixed findings, and they pointed to the need for further study. In particular, as cellular phones are a relatively new technological development, there is a need for longitudinal studies that assess the long-term consequences of frequent cell phone use.

Protecting Yourself

In the absence of clear answers, many people are left wondering about what they can do to protect themselves from cellular radiation. Although there are many safeguards you can take, the answer depends, in large part, on how often you use your phone and the level of risk you feel it poses. People who use cell phones very rarely (e.g., children or elderly who have phones that are only for use in emergencies) are not likely at risk for adverse outcomes.

People who use cell phones regularly, however, would be well advised to consider some form of protection. These days, there are a number of devices that can shield you from cell phone radiation while still allowing your phone to function at optimal capacity. Take some time to research the full range of options and to decide whether a phone shield makes sense for you.
