Radiation from mobile phones can affect your memory

WASHINGTON D.C. : Mobile phone radiation may affect memory performance in adolescents, according to a new study.

The rapid evolution of information and communication technologies (ICT) goes along with an increase in exposure to radiofrequency electromagnetic fields (RF-EMF) in our daily life.

The most relevant exposure source to the brain is the use of a mobile phone close to the head.

-Media usage and brain exposure in young adults
The study found that cumulative RF-EMF brain exposure from mobile phone use over one year may have a negative effect on the development of figural memory performance in adolescents, confirming prior results published in 2015. Figural memory is mainly located in the right brain hemisphere and association with RF-EMF was more pronounced in adolescents using the mobile phone on the right side of the head.

“This may suggest that indeed RF-EMF absorbed by the brain is responsible for the observed associations.” said Martin Roosli.

Other aspects of wireless communication use, such as sending text messages, playing games or browsing the Internet cause only marginal RF-EMF exposure to the brain and were not associated with the development of memory performance.

“A unique feature of this study is the use of objectively collected mobile phone user data from mobile phone operators.” said Roosli. He emphasised that further research is needed to rule out the influence of other factors.

“For instance, the study results could have been affected by puberty, which affects both mobile phone use and the participant’s cognitive and behavioural state.”

The data gathered from the Health Effects Related to Mobile phone usE in adolescentS (HERMES) cohort looked at the relationship between exposure to RF-EMF and development of memory performance of almost 700 adolescents over the course of one year. Participants, aged 12 to 17 years, were recruited from 7th to 9th public school grades in urban and rural areas of Swiss-German speaking Switzerland.

-Minimising the risk of RF-EMF exposure
The potential effect of RF-EMF exposure to the brain is a relatively new field of scientific inquiry. “It is not yet clear how RF-EMF could potentially affect brain processes or how relevant our findings are in the long-term.” said Roosli.

“Potential risks to the brain can be minimised by using headphones or the loud speaker while calling, in particular when network quality is low and the mobile phone is functioning at maximum power.”

The study has been published in the journal Environmental Health Perspectives.

لا تزال الدراسات التي تربط بين استعمالات الهواتف الذكية والتأثيرات السلبية على صحة مستخدميها تتوالى، وآخرها الصادر عن المعهد السويسري للصحة الاستوائية والعامة.

وأشارت الدراسة -التي أجراها المعهد- إلى أن الإشعاعات الصادرة عن الهواتف الذكية قد تؤثر سلباً على الذاكرة.

ودرس الباحثون العلاقة بين التعرض للإشعاع (RF-EMF) من الهواتف الذكية والذاكرة لدى الشبان ممن يدمنون على الهواتف الذكية، ووجدوا أن تعرض الدماغ لهذا الإشعاع خلال 12 شهراً قد ترك آثاراً لا تحمد عقباها على أدمغة مراهقين تتراوح أعمارهم بين 12 و17 عاماً.

وشارك في الدراسة 700 مراهق ومراهقة لمدة عام واحد، بغية معرفة ما إذا كان الإشعاع الصادر عن هواتفهم الذكية يؤثر على ذاكرتهم، بحسب موقع صحيفة «ميرور» البريطانية.

ووفقاً للنتائج، فإن الأشعة التي تدخل أذن مستخدم الهاتف تسبب نوعاً من الخلل في أداء الذاكرة لدى المراهقين، باعتبارهم أكثر شريحة تستخدم الهواتف الذكية من حيث الوقت.

وأوضح الباحثون أن هناك حاجة إلى مزيد من الدراسات لاستبعاد تأثير العوامل الأخرى.
