Mobile Phones and Ageing

At the moment, there is no firm proof of the
long-term effect of using mobile phones. Some
of the warnings are anecdotal, but many are based on solid research. Though limited use of mobile phones is
considered harmless, there is concern that the damage can accumulate with time, causing
irreversible effects.
Radiation and free radicals Mobile phones emit microwave radiation and most
work between the frequencies 400-1780 MHz. Depending
on a) the power of the device, b) the time one spends talking on the phone, and c) how far
away from the body the device is held, there are several ways by which radiation can
accelerate ageing. In experiments, the radiation was found to increase production of free
radicals in brain tissues. Free radicals damage tissue and organs and are a known cause of
ageing. What does radiation do?
When emitted from mobile phones it can disrupt the function of brain cells, and particularly affect the cell membrane - the transmission of signals from one cell to another - and calcium metabolism within the cell. Acetylcholine, a chemical involved in memory, may also be affected.
Mobile phone radiation can also disrupt DNA and cause difficulties in its normal repair
mechanisms. Short-term exposure to radiation causes mild DNA damage which is repaired
easily, but longer exposure may affect cells which do not generally renew throughout life
(such as brain cells), so the damage stays unrepaired and accumulates over time to cause
effects similar to those seen in normal ageing.
Vulnerable
parts of the body
The brain is relatively protected against
radiation, depending on the thickness of the skull. If the phone is kept for long periods
on other parts of the body (such as in a plastic holder on the waist) this causes further
damage because soft parts of the body are not protected against radiation as efficiently
as the brain. The absorption of radiation is increased by
metallic items such as earrings, metallic spectacle frames and metal tooth implants or
fillings. These act as re-radiating antennae and, with time, enhance and amplify the
effects of radiation.
Is there a risk of cancer?
Researchers from North Carolina report that
radiation accelerates ageing of certain human cells (endometrial cells) which become
unable to function properly and cannot restrain cancerous cells, thus cancerous cells
remain free and could multiply. Low level radiation also increases the formation of heat
shock proteins (HSP). These are proteins formed by normal cells when exposed to damage, a
common phenomenon during ageing. HSP act as a scaffolding to help repair
damaged body proteins. They are a sign that damage has been caused somewhere in the body.
Radiation may cause free radical damage and
other damage to the eye, contributing to cataract and macular degeneration, two common
age-related eye conditions.
The immune system may be affected and also
melatonin, which regulates the sleep-wake cycle and which may play a role in preventing
age-related damage. Finally, radiation interferes
with serotonin production, which has the effect of reducing feelings of well-being and
increasing depression. Again, it must be stressed that there is more
research needed, and the findings are not conclusive.
However, most experts agree that if the exposure is maintained over many years
(life-long), then the radiation effects described above are likely to become more
pronounced. How to minimise damage from mobile phones:
Dr Marios Kyriazis book The Anti-Aging Plan contains information on ageing and age-related diseases, including conventional and complementary treatments. If in any doubt about any of the information covered in any health related article and its relevance for you, consult your GP.
