Mobile Phone Use and Cognitive Functions

In Environmental Health Perspectives, Milena Foerster, Arno Thielens, Wout Joseph, Marloes Eeftens, and Martin Röösli report findings that suggest potential adverse effects of adolescents’ mobile phone use on cognitive functions.

We found preliminary evidence suggesting that RF-EMF may affect brain functions such as figural memory in regions that are most exposed during mobile phone use. Our findings do not provide conclusive evidence of causal effects and should be interpreted with caution until confirmed in other populations. Associations with media use parameters with low RF-EMF exposures did not provide clear or consistent support of effects of media use unrelated to RF-EMF (with the possible exception of consistent positive associations between verbal memory and data traffic duration). It is not yet clear which brain processes could be potentially affected and what biophysical mechanism may play a role. Potential long-term risk can be minimized by avoiding high brain-exposure situations as occurs when using a mobile phone with maximum power close to the ear because of, for example, bad network quality.

iGen

In the FT, Leslie Hook reports that activist investors want Apple

to address concerns over smartphone addiction and the mental health effects of phone use among children.

They refer to psychologist Jean Twenge according to whom teenagers today (“the iGen”)

… are more vulnerable than Millennials were: Rates of teen depression and suicide have skyrocketed since 2011. It’s not an exaggeration to describe iGen as being on the brink of the worst mental-health crisis in decades. Much of this deterioration can be traced to their phones. …

12th-graders in 2015 were going out less often than eighth-graders did as recently as 2009. …

Teens who spend more time than average on screen activities are more likely to be unhappy, and those who spend more time than average on nonscreen activities are more likely to be happy. There’s not a single exception. All screen activities are linked to less happiness, and all nonscreen activities are linked to more happiness.

The last observation does not hold in the cross section, however; more “social” teenagers spend more time with friends both online and offline.
