Many research links the use of smartphones to mental health problems, but a new study has found even worse.
According to the newspaper "Independent" British, the use of smart phones may harm children, especially on users who are not more than two years old.
The study, published in the Journal of Preventive Medicine reports, said the use of the phone for only one hour may cause the child and adolescent to suffer from anxiety and depression, as well as reduce his ability to exercise restraint and emotional stability.
Researchers found that adolescents aged 14 to 17 were more likely to have these negative effects, noting that negatives are worse when the child's brain is growing and developing.
"Children in the nursery are very much using smart phones. This may weaken their ability to control their calm and nerves in the future."
Children between the ages of 11 and 13, who spend an hour a day on phone screens, lose the opportunity to "learn new things" or, in particular, lose "curiosity about learning," according to the study.
