Summer screens and teens

A Psychology Today Australia article published April 22 said summer’s loose routines can push teens toward heavier screen use and new mental-health warning signs. (psychologytoday.com) Lance Garrison, a psychologist writing in the magazine’s “Collaborative Care” column, said the risk rises when adolescents’ developmental vulnerabilities meet platforms built for “likes, streaks, and social comparison.” He said primary care providers are often among the first professionals to spot trouble. (psychologytoday.com) The article pointed parents to behavior changes rather than raw hours alone: irritability after being offline, late-night scrolling that disrupts sleep, sudden drops in self-esteem, body dissatisfaction, anxiety tied to peer interactions, and withdrawal from offline activities or family life. (psychologytoday.com) That warning lands into a broader public-health debate that has shifted from “how many hours” to “what kind of use.” The U.S. Surgeon General said social media is “not sufficiently safe” to be assumed harmless for children and adolescents. (hhs.gov) The same federal advisory said up to 95% of U.S. teens ages 13 to 17 use a social-media platform, about one-third say they use it “almost constantly,” and more than three hours a day is linked to double the risk of depression and anxiety symptoms. It also said 46% of adolescents ages 13 to 17 reported that social media made them feel worse about their body image. (hhs.gov) Researchers have also narrowed in on why adolescence is a sensitive period. A 2024 review in *Nature Reviews Psychology* said social media can intensify social comparison, sensitivity to feedback, exclusion, stress, and reward-seeking during a stage when those systems are already changing quickly. (nature.com) Large population studies are finding similar patterns across countries. The World Health Organization said in September 2024 that problematic social-media use among 11-, 13-, and 15-year-olds in 44 countries and regions rose from 7% in 2018 to 11% in 2022, based on a survey of nearly 280,000 young people. (who.int) The World Health Organization said girls reported higher levels of problematic social-media use than boys, 13% to 9%, while 36% of adolescents reported constant online contact with friends and 44% of 15-year-old girls reported that level of contact. (who.int) In Australia, the Black Dog Institute’s “Teens and Screens” report drew on 2023 data from 3,734 adolescents in the Future Proofing Study and said the relationship between screen use and mental health is “complex.” The New South Wales education department updated its summary of that report on April 9, 2026. (education.nsw.gov.au) U.S. government researchers reported in 2025 that teens with four or more hours of daily non-school screen time were more likely to report depression symptoms, anxiety symptoms, irregular sleep, low social and emotional support, and insufficient peer support, using 2021–2023 National Health Interview Survey-Teen data. (cdc.gov) A National Academies consensus report published in February 2024 said the evidence does not support a simple one-way claim that more social media automatically causes worse mental health in every teen. It said the relationship is more complex and depends on the young person, the content, and the context of use. (academic.oup.com) That leaves summer as a stress test for families: fewer school guardrails, more idle hours, and more chances for sleep loss, comparison, and conflict to show up first as mood or behavior changes. Garrison’s article said those shifts, not a single screen-time number, are the signs to watch. (psychologytoday.com)
