It is increasingly clear that children today are facing a severe mental health crisis, with rising cases of self-harm, suicidal thoughts, social isolation, OCD, and eating disorders. As therapists, we speak daily with distressed parents watching their children struggle with anxiety and depression, often wondering what is driving this significant decline in childhood wellbeing.
While several factors, including academic pressure, extended parental working hours, and reduced opportunities for free play, are contributing to the problem, no single factor has had more impact than the smartphone and constant internet access, particularly social media.
Smartphones and the internet are relatively new phenomena, and parents, carers, and even society as a whole were not prepared for their impact. Though previous generations worried about the effects of television or video games, these concerns seem minor in comparison to the harm caused by smartphones and social media. We’ve cried wolf one too many times—this time, the damage is real, and it is severe. Children’s mental health has significantly deteriorated, and it is essential to understand why.
Teenagers are at a stage where they are developing their identities, a process that is heavily influenced by their peers. Social media, however, skews this natural development by presenting only the most extreme highs and lows of others’ lives—often exaggerated or entirely fabricated. Teens compare themselves to this distorted reality, internalising the belief that they are not as happy, successful, or attractive as their peers, leading to profound insecurity.
This is particularly damaging for girls, whose social media feeds often focus on body image and social status, negatively impacting their sense of self.
“Lives on social media are always exaggeratedly wonderful or awful, traumatic, and extreme. This leaves adolescents trying to form an identity in a hall of mirrors, with the reflections of themselves and others completely distorted. It takes a strong adolescent to filter the noise of social media and find their own authentic way of developing.” – Ryan Lowe, Clinical Director of The Therapeutic Consultants
Alongside rising mental health issues, there is a documented increase in the diagnosis of neurodevelopmental disorders such as ADHD and Autism Spectrum Disorder (ASD). This rise seems to align with increasing screen time in young children. Screen overuse can overstimulate their developing minds, making it difficult to concentrate on slower-paced activities and reducing face-to-face interaction, crucial for developing social skills. These trends may be contributing factors to the increased rates of neurodiversity.
It’s not just children who are constantly on their devices—parents too often find themselves glued to their screens. Whether driven by work demands or social media habits, this shift has led to less direct communication within families. The expectation to be available at all times means that when a parent’s phone pings, their child feels ignored, often triggering feelings of rejection, which can manifest as anxiety or behavioural issues.
Children today have fewer opportunities to engage in risky play, which is crucial for building resilience and managing anxiety. While it may seem safer for children to be inside playing on their devices, this comes at the cost of real-world experiences that foster emotional strength and problem-solving skills. By sheltering children from risk, we inadvertently make them more vulnerable to anxiety.
This trend may be linked to growing parental anxiety, with many adults struggling to manage their own stress and uncertainties, making it difficult to model healthy emotional regulation for their children.
In a significant move to combat the rising mental health crisis among children, Florida passed a landmark law in May 2023, prohibiting smartphone use in classrooms. Governor Ron DeSantis championed this legislation, which not only limits phone use during school hours but also blocks access to social media on school networks. This pioneering initiative aims to reduce screen time and promote mental well-being, signalling the state’s commitment to fostering a healthier educational environment for students.
Thankfully, professionals in the field are starting to make sense of the problem. Experts like Jonathan Haidt, Jean Twenge, and Lenore Skenazy are conducting research into the negative effects of smartphones and social media on childhood development. In particular, Jonathan Haidt’s book The Anxious Generation delves into the psychological and social consequences of living in a hyper-connected world.
Here in the UK, the Smartphone-Free Childhood movement, started by two mothers at a local school, has become a national sensation, resonating with parents across the country. This movement encourages reducing screen time, promoting free play, and encouraging face-to-face interaction—key ingredients for a healthy, resilient childhood.
The increasing awareness around the damage caused by smartphones and social media, coupled with legislative changes, gives hope that we are finally starting to address these urgent issues. Parents, carers, and society as a whole must continue to push for screen-free childhoods, providing young people with the tools they need to develop into resilient, emotionally healthy adults.
