The link between social media and youth mental health It's back at the center of the debate. A new study published in the medical journal JAMA Network Open suggests that slowing down on platforms like Instagram and TikTok This can translate, in just one week, into fewer symptoms of anxiety, depression, and even sleep problems in young adults.
Far from the alarmist headlines, the study suggests that it's not just about how many hours we spend on our phones, but about how we use those apps and what kind of relationship we have with them. Reducing network use seems to work best as complement to other mental health care that is seen as a miracle solution, but the data gives families, professionals and public policy makers in Europe also much to think about.
An experiment with young people aged 18 to 24
The research was conducted in the United States between March 2024 and March 2025 with 373 young adults The participants were aged 18 to 24, an age group very similar to that of Spanish and European university students. To participate, they needed a compatible mobile phone and to agree to have their activity monitored through the app. mindLAMP applicationThis allowed us to collect objective data beyond what each person said about using the phone.
The design consisted of a first phase of two weeks of observationin which digital habits and emotional state were recorded without asking for behavioral changes. Afterwards, those who wished continued with a voluntary seven-day intervention, a kind of social media “detox”, in which they were asked to minimize their use of five platforms: Facebook, Instagram, Snapchat, TikTok and X.
Of the initial 373 participants, 295 completed that week of reduction. Everyone was given standardized questionnaires about depression, anxietyinsomnia, loneliness and problematic patterns of network use, both before and after the experiment, similar to how it is done in many European clinical studies.
In addition to this subjective aspect, the app and the mobile phone's sensors collected metrics such as screen timeunlock frequency and mobility patterns (for example, how much time they spent away from home), a technique known as “digital phenotyping” which is increasingly used in psychiatry and psychology.
Results: less depression, anxiety, and insomnia
After just seven days of trying to use less social media, the group that completed the intervention showed changes that the authors consider clinically relevantOn average, depression symptoms were reduced by 24,8%anxiety decreased 16,1% and sleep problems (insomnia) decreased 14,5% with respect to the initial levels.
These improvements were especially marked in those who started from a background of moderate or severe depressionIn that subgroup, the drop in indicators of emotional distress was greater than average, suggesting that people already affected may notice the effect of reducing Instagram, TikTok and similar apps more, something very relevant for European countries where youth depression is an increasing concern.
However, the study did not detect significant changes in the feeling of lonelinessThe authors argue that, while these platforms can worsen some aspects of mental health, they also fulfill an important social function: abruptly cutting off certain networks could reduce distress, but also limit the feeling of connection with the peer group, something key in adolescence and early adulthood.
One detail that breaks some stereotypes: during the "detox" week, the time spent specifically on social media fell from approximately 1,9 hours a day at about 30 minutesThat is, about a quarter. However, the total mobile phone usage time It didn't collapse, but even rose slightly.
According to the data collected, global smartphone use increased by around 4,5% and the time participants spent at home grew by nearly a 6,3%In other words, they stopped endlessly scrolling on TikTok or constantly checking Instagram, but those activities replaced through other digital means: messaging, web browsing, video games, or other apps.
It's not the screen, it's how we use it.
One of the most interesting conclusions of the study is that the impact on mental health does not seem to depend so much on the absolute time in front of the screenbut rather the type of interaction with the platforms. The data suggests that clearly problematic behaviors—such as negative social comparison— uncontrollably checking the feed or emotional dependence on likes — are the ones most related to symptoms of depression, anxiety and insomnia.
In fact, even when young people continued to spend more minutes on their phones overall, simply reducing their use of platforms like Instagram and TikTok, with their mix of idealized lives, filters, and highly curated content, seemed to alleviate some of the unease. This nuance aligns with the view of several European specialists, who insist that the real problem is... addictive and comparative usenot just any digital activity.
The study also supports the idea that breaks or occasional reductions—what is popularly called a “digital disconnection”— they can have rapid, albeit modest, effects on mood. Compared to traditional therapeutic interventions, which often take weeks or months to show results, limiting Instagram and TikTok use for a week is a measure cheap, simple and affordable of the majority.
However, the authors remind us that these changes do not make a social media “detox” a magic bullet or an alternative to psychotherapy or medication when they are needed. As the psychiatrist emphasizes John TorousAccording to the co-author of the study and professor at Harvard Medical School, reducing social media use "would not be the first or only line of treatment," but it can be a companion tool that many people can try without great risks.
Along those lines, several experts consulted in different media outlets point out that, if someone is already in treatment for a mental health problem, it may make sense to experiment with supervised breaks social media to see if they help you feel a little better, always with realistic expectations and without falling into simplistic solutions.
Instagram and Snapchat, the hardest to let go of
By analyzing digital behavior in detail, researchers saw that not all platforms shrink with the same ease. While most managed to significantly reduce the time spent on TikTok or XInstagram and Snapchat were another story: a significant portion of users did not achieve a clear reduction in their consumption.
Specifically, the study indicates that approximately one 67,8% of those who used Instagram or with a 48,8% of Snapchat users They failed to maintain any real restraint, not even during that single week. In other words, they continued to connect to these apps quite frequently despite the "detox" instructions.
This data coincides with the everyday experience of many young Europeans, for whom Instagram is almost a “social card” And Snapchat is a constant channel of communication with the group. Recommendation algorithms, streaks, ephemeral stories, and the fear of missing out (the famous FOMO) make it especially popular. complicated to let go These apps, even if you try hard enough.
For parents, educators, and policymakers in Spain and other EU countries, this distinction is relevant: not all social networks pose the same level of challenge when it comes to moderating their use. School programs or public campaigns that encourage “using less social media” may need to focus specifically on Instagram, TikTok and Snapchat, rather than in generic screen time.
At the same time, the authors are cautious about the idea of completely banning these platforms, both in educational settings and at a regulatory level. Torous warns that a total ban could have unwanted effects, especially in terms of socialization, and advocates for more nuanced approaches, aimed at reducing problematic use rather than cutting it off completely.
An open debate and still mixed evidence
The findings come in a context of very intense debate on the role of mobile phones and social media in the mental health of Generation Z. Figures such as the social psychologist Jonathan Haidt They have pointed to the smartphone as one of the main culprits behind the decline in psychological well-being in adolescents and young people, which has prompted measures to limit phone use in schools and educational centers in several countries.
Other specialists, however, urge caution. They point out that previous scientific literature on “digital detoxes” It has yielded very disparate results. Some recent meta-analyses have found positive, but small, effects, while others conclude that the overall average impact of these breaks is practically nonexistent.
In this specific case, several researchers point out that the study design has major limitationsThis was not a classic randomized clinical trial with a randomly assigned control group that maintained its usual consumption; the young people themselves voluntarily signed up for the reduction of networks, something that can introduce motivational and expectation biases.
Experts like psychologist Christopher Ferguson point out that, without a clear comparison to a control group, the improvement figures can be difficult to interpret. Others, like researcher Candice L. Odgers, remind us that if we've been repeating for years that social media is bad and that taking a break is good, it's quite likely that people who agree to pause their use will actually benefit. expect to feel better and reflect this in the questionnaires.
Nevertheless, there are also voices that see these results as a further step in the same direction as other studies. Psychologist Mitch Prinstein, of the American Psychological Association, interprets the study as part of a body of evidence suggesting that, on average, Those who stay away from social media for a while often notice some improvement. in depression, anxiety and loneliness, even if it is modest and not universal.
The key, several authors agree, is that not everyone reacts the same way. In these types of interventions there is a enormous individual variabilitySome improve considerably, others barely notice any changes, and a few might even worsen if they feel isolated by ceasing to use the platforms that connect them with their social environment.
What can this study contribute in Spain and Europe?
Although the research was conducted in the United States, its conclusions align with concerns that are very present in Spain and the rest of Europe: an increase in emotional distress Among teenagers and university students, there are debates about banning mobile phones in schools or imposing age limits for opening social media accounts, and parents who don't quite know how to manage their children's use of Instagram, TikTok, or Snapchat.
The paper published in JAMA Network Open doesn't offer definitive solutions, but it does offer some useful clues. For one thing, it suggests that proposing to young people structured reductions Limiting the use of social media—for example, spending a week on the main platforms for half an hour a day—can be a reasonable, inexpensive, and, for many, beneficial intervention.
On the other hand, remember that the focus should be less on simply counting screen time and more on detecting harmful usage patternsCompulsive use, dependence on social feedback, passive and comparative consumption of content, and displacement of sleep or important offline activities. In Europe, where regulations for digital platforms are being developed, this nuance can help to better guide policies.
It also makes it clear that we cannot place all the responsibility on the individual. If Instagram and TikTok are designed to maximize time spent on the platform and interaction, asking a young person to “simply use them less” without changes to the app design or the social environment is, in many cases, make things very difficult for himThat is why some experts advocate combining digital education, reasonable limits in schools, and regulations that reduce the most addictive behaviors.
The study reinforces an idea that is increasingly heard among both clinicians and families: lower the volume on Instagram and TikTok It doesn't fix everything, but it can be another piece of the puzzle to alleviate anxiety and depression in young people, as long as it is done consciously, adapted to each person and without forgetting that, behind the screen, there is a whole life that should be taken care of at least as much as the number of notifications.
