This study investigated the effect of 2.45 GHz microwave radiation (2 h/day for 45 days) on biomarkers within Wistar rats. A significant decrease (P < 0.05) was recorded in the level of pineal melatonin of exposed group as compared with sham exposed, while a significant increase (P < 0.05) in creatine kinase, caspase 3, and calcium ion concentration was observed in whole brain of exposed group of animals as compared to sham exposed. The study concludes that a reduction in melatonin or an increase in caspase-3, creatine kinase, and calcium ion may cause significant damage in brain due to chronic exposure of these radiations. These biomarkers clearly indicate possible health implications of such exposures.
Changing technology and methods of use. Older studies evaluated radiofrequency radiation exposure from analog cell phones. Today, cell phones use digital technology, which operates at a different frequency and a lower power level than analog phones. Digital cell phones have been in use for more than two decades in the United States, and cellular technology continues to change (3). Texting and other applications, for example, are common uses of cell phones that do not require bringing the phone close to the head. Furthermore, the use of hands-free technology, such as wired and wireless headsets, is increasing and may reduce exposure by distancing the phone from the body (36, 37).

Thankfully, small steps lead to big changes. Let's travel this road together, one step at a time.
20. Remember to focus on driving. “Don’t look up phone numbers, don’t take notes or play with your PDA (personal digital assistant) while driving. These activities prohibit you from watching where you are going. Of course, you shouldn’t read the paper, apply eye make-up or write notes while driving either! Driving is serious business.” – How to Hear in a Hands-Free World: Mobile and Cell Phone Safety Tips, AudiologyOnline; Twitter: @audiologyonline
