No doubt, exposure to RF radiation emitted from mobile phones may cause some detrimental effects. However, in some special circumstances, these radiations may cause some stimulatory or beneficial effects. Our team is currently preparing a review article on the stimulatory/beneficial effects of exposure to mobile phone radiation.

Some detrimental effects of exposure to electromagnetic fields
have also been reported by our team!

10. EMF-related Subjective Symptoms
• Some cell phone users
report symptoms such as
headache, dizziness,
tinnitus, insomnia,
attention and concentration
problems, myalgia, fatigue
and palpitation after talking
too long.
• However, no significantly
higher prevalence of self-
reported symptoms was
found in our studies.

• No significantly higher prevalence of self-reported symptoms was
found in individuals who had used mobile phones, video display
terminals or cordless phones more frequently than others.
• Mass-media’s lack of interest in the possible hazards of exposure
to EMF in developing countries can explain the difference
observed between the results of this study and those of other
researchers in some developed countries who have shown an
association between EMF exposure and the prevalence of self-
reported subjective symptoms.
• This finding can confirm the results obtained in provocative
studies which indicated the role of psychological factors in
electromagnetic hypersensitivity.

• No statistically significant changes between the
means of the biological parameters such as heart
rate, respiration, and blood pressure in
real/sham exposure were observed.
• Our findings clearly confirm the results obtained
in other provocative studies.
• These data also indicate the possible role of
psychological factors in electromagnetic
hypersensitivity.

Cognitive Beneficial Effects
• On the other hand, the potential beneficial
effects of (RF) radiation are not only limited to
the induction of adaptive phenomena.
Previously, we have indicated that the visual
reaction time (VRT) of university students was
significantly affected by a 10 min exposure to
electromagnetic fields emitted by a mobile
phone (7).

29. Radiofrequency Radiation –Induced
Cognitive Beneficial Effects
• Furthermore, we have shown that occupational
exposures to radar radiations decreased reaction
time in radar workers.
• Altogether our results revealed that these
exposures caused decreased reaction time which
might lead to a better response to different
hazards and decrease the probability of human
errors and fatal accidents.

Children
• A total of 60 elementary school children ages
ranging from 8 to 10 years studying at a public

in a study. It was shown that short-term
exposure of elementary school students to RF
radiation leads to the better performance of their

35. Radiofrequency Radiation –Induced
Cognitive Beneficial Effects
• On the other hand, cognitive beneficial effects of
long term exposure to high frequency EMF have
been indicated by some studies.
• Using a word interference test, in 2007, Arns et
al. showed that long term heavy cell phone use
resulted in better performance of normal
subjects.

36. Radiofrequency Radiation –Induced
Cognitive Beneficial Effects
• Moreover, Schuz et al. in 2009 reported that
long-term cell phone users (subscribers of 10
years or more) had a 30–40% decreased risk of
hospitalization due to AD and vascular dementia
(10).

38. Challenging Arendash’s Report
• Recently, Arendash reported that long-term
transcranial electromagnetic treatment (TEMT)
can prevent and reverse both cognitive
impairment and brain amyloid-β (Aβ) deposition
in AD transgenic mice.
• He also claimed that TEMT even improves
cognitive performance in normal mice.

41. Radiofrequency Radiation –Induced

• In this light, a challenging issue will be if there
are other RF-induced stimulating effects and
to explore the potential applications of these
effects. Further research may shed light on
dark areas of the health effects of short and
long-term human exposure to radiofrequency
radiation.
