Harmful effects of mobile phones on the body

It was a long way that started with the messenger pigeon as a news carrier to reach to the modern small pocket packed gizmos, which we define as mobile or cellular phone. But whoever imagines that this small, powerful utility will cause multiple health hazards to the human being? All we need is your attention to go through the article.

Harmful effects of mobile phones on the body

How common is brain cancer? Has the incidence of brain cancer changed over time? Why is there concern that cell phones may cause cancer or other health problems?

Cell phones emit radiofrequency energy radio wavesa form of non-ionizing radiation, from their antennas. Tissues nearest to the antenna can absorb this energy. As of Decemberthere were more than This is a nearly threefold increase from the million users in Globally, the number of subscriptions is estimated by the International Telecommunications Union to be 5 billion.

However, improvements in cell phone technology have resulted in devices that have lower power outputs than earlier models. The NCI fact sheet Electromagnetic Fields and Cancer includes information on wireless local area networks commonly known as Wi-Ficell phone base stations, and cordless telephones.

What is radiofrequency energy and how does it affect the body? Radiofrequency energy is a form of electromagnetic radiation. Electromagnetic radiation can be categorized into two types: Electromagnetic radiation is defined according to its wavelength and frequency, which is the number of cycles of a wave that pass a reference point per second.

Electromagnetic frequencies are described in units called hertz Hz.

QUICK FACTS: The Harmful Effects Of Cell Phone Radiation

The energy of electromagnetic radiation is determined by its frequency; ionizing radiation is high frequency, and therefore high energy, whereas non-ionizing radiation is low frequency, and therefore low energy.

More information about ionizing radiation can be found on the Radiation page. The frequency of radiofrequency electromagnetic radiation ranges from 30 kilohertz 30 kHz, or 30, Hz to gigahertz GHz, or billion Hz.

The human body absorbs energy from devices that emit radiofrequency electromagnetic radiation. The dose of the absorbed energy is estimated using a measure called the specific absorption rate SARwhich is expressed in watts per kilogram of body weight. Exposure to ionizing radiation, such as from x-rays, is known to increase the risk of cancer.

The only consistently recognized biological effect of radiofrequency energy is heating. The ability of microwave ovens to heat food is one example of this effect of radiofrequency energy.

However, it is not sufficient to measurably increase body temperature, and there are no other clearly established effects on the body from radiofrequency energy. Whereas one study showed increased glucose metabolism in the region of the brain close to the antenna compared with tissues on the opposite side of the brain 2the other study 3 found reduced glucose metabolism on the side of the brain where the phone was used.

The authors of these studies noted that the results are preliminary and that possible health outcomes from changes in glucose metabolism are still unknown. Such inconsistent findings are not uncommon in experimental studies of the biological effects of radiofrequency electromagnetic radiation 5.

Some contributing factors include assumptions used to estimate doses, failure to consider temperature effects, and lack of blinding of investigators to exposure status. How is radiofrequency energy exposure measured in epidemiologic studies?

Direct measurements are not yet possible outside of a laboratory setting. Estimates take into account the following: Radiofrequency energy, unlike ionizing radiationdoes not cause DNA damage that can lead to cancer.

Its only consistently observed biological effect in humans is tissue heating. In animal studies, it has not been found to cause cancer or to enhance the cancer-causing effects of known chemical carcinogens 6 — 8. This investigation was conducted in highly specialized labs that can specify and control sources of radiation and measure their effects.

In Februarytwo draft technical reports summarizing the findings were made available in advance of the formal peer-review process in March Peer review is a critical component of the scientific process to ensure that research findings are meaningful, accurate, and appropriately interpreted.The shocking effect of cell phone radiation Not sure about the health effect of cell phone radiation on your body?

Are you familiar with the health effects of mobile phone EMR? Besides the number of cell phone calls per day, the length of each call and the amount of time people use cell phones are important factors which enhance the health related risk.

5 Ways Cell Phones Harm Your Health

Mobile phones emit radiofrequency energy, a form of non-ionizing electromagnetic radiation, which can be absorbed by tissues close to the phone.

January 15, By Healthy Living How To 1 Comment We all know it by now, cell phones emit radio-frequency energy. The one thing still up for debate is whether or not this radio-frequency energy is harmful to the human body, and if it is to what extent.

Mobile phones are quite useful in studies and business.

Harmful effects of mobile phones on the body

In both fields, the mobile phone has become like compulsory gadget. Students can access Internet on their mobile phones while on the go, and thus can get knowledge of any topic they wish to. The ability of microwave ovens to heat food is one example of this effect of radiofrequency radiation.

Radiofrequency exposure from cell phone use does cause heating to the area of the body where a cell phone or other device is held (e.g., the ear and head). However, it is not sufficient to measurably increase body temperature.

The real effect of cell phone radiation. The health effect of cell phone radiation varies from person to person and is directly related to the amount of exposure the person has had, but many of the more common health effects of mobile phone EMR include nausea, dizziness, blurred vision, hearing loss, migraine headaches, neurosis of the brain, and brain tumors, or even brain cancer.
