A study at Örebro University in Sweden indicates that mobile phones and other cordless telephones have a biological effect on the brain. It is still too early to say if any health risks are involved, but medical researcher Fredrik Söderqvist recommends caution in the use of these phones, above all among children and adolescents. Few children who regularly use mobile phones use a headset often or always, even though the Swedish Radiation Safety Authority recommends this.
“Children may be more sensitive than adults to radiation from wireless phones,” says Fredrik Söderqvist, who is presenting his research findings in a new doctoral thesis at Örebro University.
On the one hand, he examined the use of wireless telephones among children and adolescents, on the other hand, whether adolescents themselves perceive any health problems that might be related to this use.
He then went on to study blood samples from adults, looking at two so-called biomarkers to see whether wireless phone use has a biological effect on the brain. One of these studies focused on a protein that exists in the so-called blood-cerebrospinal-fluid barrier, which is part of the brain’s protection against outside influences. The study revealed an association between use of wireless telephony and increased content of the protein transthyretin in the blood.
