The emergence of cellular phones in our modern lives has become a prevailing necessity. Nowadays, vast majority of the world population are hooked with this tiny yet powerful gadget. From a simple device that served only as a call and text now becomes a communication tool package that knows no limits. Mobile or cellular phones have thus become indispensable.

But little did we know of the dangers it poses to our health. Serious concern is escalating over the years on the mushrooming use of the handy mobile cellular telephone, or cell-phone. These phones are arguably the most radioactive appliance humans have yet invented. It is well known that high levels of RF (Radio Frequency) can produce biological damage through heating effects, same as how our microwave oven works.

The effect of this radio frequency (RF) is very alarming to us humans. As high frequency radio radiation penetrates the body, the exposed molecules move about and collide with one another causing friction and heat. If the radiation is powerful enough, the tissue or skin will be heated or burned. Synonymous to this is the EMF (electromagnetic frequency) radiation describes the continually flowing electrons that form invisible fields of energy all around us. EMF radiation from power lines, appliances, radars, TVs, phones, computers, microwaves, etc. are already considered by many to be potentially hazardous to both mental and physical health. Those who live or work within an electromagnetic field is at risk.

Studies have shown that cell phones have been linked with a wide range of health problems including headaches, earaches, eye and vision problems, memory loss, nausea, fatigue, brain tumors, or even DNA alteration or damage and even changes in the brain's electrical activity. Researches particularly the effects among children and pregnant mothers are alarming.

What about Wi-Fi computer signals? Can they interfere with sleep? The scientific jury is still out, but consider this: Kevin Koym, who owns a consulting company and a software engineering firm in Austin, Tex., says of his struggles with insomnia: "I never had sleep problems until I started using Wi-Fi So now I am careful to shut off my computer at home in the evening."

For years, much have been rake over and publicized of the many lawsuits filed against cell phone companies. Countries like US, Great Britain, Austria, Germany, Sweden etc. have undertaken measures to delve into the issue and made strong regulations for the telecommunication industry. The concern has been strong and on-going. The extent of these safety issues lies on the fact that needs not be taken for granted.
