A recent study indicates that cell phones and other cordless telephones have a biological effect on your 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.
Söderqvist studied blood samples, 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 blood-cerebrospinal-fluid barrier, which is part of your brain's protection against outside influences. The study revealed an association between use of a cell phone and increased content of the protein transthyretin in the blood.
This indicates that your brain is in fact affected by microwaves from cell phones, meaning that there may be other -- as yet unknown -- effects that may impact your health.
