A comprehensive new report released last week by the nonprofit research organization Sapien Labs reveals that 41% of internet-enabled young adults aged 18 to 34 are experiencing a “mind health crisis” that significantly hinders their ability to lead productive lives. The finding is based on data collected from approximately 1 million individuals across 84 countries.
The Global Mind Health in 2025 report, compiled by experts in neuroscience, psychology, and computational science, documents a striking reversal in mental well-being among younger generations. According to the research, young adults enjoyed the highest level of mental well-being of any age group as recently as the early 2000s. Today, however, they are four times more likely than adults over 55 to suffer from mental health challenges severe enough to impair daily functioning.
The study identifies four primary drivers behind this decline: the early adoption of smartphones in childhood, increased consumption of ultra-processed foods, deteriorating family relationships, and a diminishing sense of spirituality. Researchers found that these factors collectively contribute to struggles that extend beyond depression and anxiety, affecting emotional control, focus, and the ability to maintain relationships.
Tara Thiagarajan, the report’s lead author and founder of Sapien Labs, emphasized the progressive nature of the decline. She noted that the challenges facing young adults are multifaceted and that addressing them requires looking beyond traditional mental health treatments. “We need to stop chasing the symptoms and instead begin tackling the broader problems that erode productivity and well-being,” Thiagarajan said.
The study utilized an assessment tool called the Mind Health Quotient to evaluate individuals’ cognitive, emotional, and social capacities. The findings reveal significant geographic disparities, with young adults in sub-Saharan Africa—the world’s lowest-income region—scoring substantially higher than their peers in wealthy nations such as the United States, Canada, and Australia. Researchers suggest this points to a possible inverse relationship between national wealth and mind health.
Data also showed that young adults in sub-Saharan Africa reported stronger spiritual connections and later exposure to smartphones, factors that correlated with better mental health outcomes. Nonetheless, across all countries studied, younger adults consistently fared worse than older generations.
Previous research from Sapien Labs indicates that the generational gap in mental health widened sharply during the COVID-19 pandemic and has remained largely unchanged since. Thiagarajan warned that the entry of a large cohort of young people with compromised mind health into the workforce could have serious economic repercussions.
The report calls for policy interventions such as banning smartphones in schools, establishing minimum age requirements for social media use, and increasing research into the health impacts of food additives. It estimates that ultra-processed foods alone may account for 15 to 30 percent of the mental health burden among young adults.
David Blanchflower, a professor of economics at Dartmouth College, described the findings as a wake-up call. He said the data reveal a crisis capable of undermining entire economies and societies and stressed the urgent need to address root causes rather than symptoms.
