Is screen time associated with later bedtimes and daytime sleepiness in adolescents?

A recent report from HBSC Healthy Generation points to increasingly late bedtimes as a key reason why Czech adolescents are getting less sleep today, and why a growing number of them are falling short of sleep recommendations. This lack of sleep is the main cause of daytime sleepiness. Research consistently links daytime sleepiness to a range of negative effects, including worsened school grades, mental health struggles, and a lower quality of life. In our newly published study, we explored how bedtimes and daytime sleepiness are associated with the amount of time spent on screens during the day. We were also interested in whether avoiding screens for an hour before bed makes a difference. We found an association between screen time and sleep. However, the study provided no evidence that the popular sleep recommendation to avoid screens an hour before sleep is effective in the long term.

Report: A Ban on Mobile Phones in Schools Is Not a Universal Solution

Banning mobile phones in schools does not straightforwardly lead to better academic performance of students. An analysis of data from 21 countries, including the Czech Republic, conducted by the IRTIS research team at the Faculty of Social Studies of Masaryk University, shows that although phone bans are associated with lower levels of student distraction, in several countries they are also linked to greater classroom disruption during lessons, which in turn is reflected in poorer student performance in mathematics.

Report: Generative artificial intelligence through the eyes of Czech children and adolescents

Czech children and adolescents use generative artificial intelligence (AI) most frequently for school-related tasks, particularly for writing essays or reports (42%), and for summarising or explaining longer texts (39%). Everyday use is also common, with approximately one-third of Czech children and adolescents using generative AI to get recommendations. They ask AI what to do, watch, listen to, or what to buy (29.5%). These findings are part of the research report published today on Safer Internet Day by experts from the Faculty of Social Studies at Masaryk University. The results are based on over 2,600 responses from children and adolescents aged 9–17.

Experts Don't Recommend Banning Social Media Until Age 15: Its Impacts Remain Unclear, and It Could Introduce Additional Risks

This year, Australia became the first country in the world to ban social media for children under the age of 16. Many European countries, including the Czech Republic, are also considering bans for certain age groups. Proponents of the bans argue that doing so is in the interest of children's health and healthy development. However, according to researchers from the Interdisciplinary Research of Internet and Society (IRTIS) at Masaryk University and world experts from prestigious universities, hastily conceived bans on technology use affecting the 13- to 15-year-old (or 16-year-old) age group are ineffective and potentially harmful.

Report: Half of young Czechs engage in sexting

Sexting has become a common part of the digital lives of Czech adults. More than one-third of the adult population have sent videos, photos, or text messages with sexual content, and among 18–29-year-olds, this figure reaches nearly one half. It is therefore not a marginal phenomenon but a regular aspect of intimate relationships in the digital age - one that will likely become even more widespread as younger generations grow older. These findings come from a report by the research team IRTIS at the Faculty of Social Studies, Masaryk University, based on three surveys conducted in the Czech Republic. Notably, sexting is also linked to negative experiences, with men reporting higher levels of sexual coercion than expected.

Why adolescents do not confide in their parents about online sexual solicitations?

In a recently published study, we looked at adolescents receiving online sexual solicitations. Despite the fact that receiving these messages often upsets them, many choose not to confide in their parents, thus losing a potential source of support. We investigated adolescents’ experiences with online sexual solicitations and the barriers that prevent them from confiding in their parents. The study was authored by Barbora Lisztwan Honusová, Lenka Dědková and Vojtěch Mýlek from IRTIS and published in Children and Youth Services Review.
