Physical inactivity is one of the most significant health challenges facing adolescents today, as daily movement declines and screen time increases.
The phenomenon is becoming increasingly alarming, with the World Health Organization revealing that one in four adolescents worldwide did not engage in at least 60 minutes of physical activity on any day of the week prior to the survey.
The findings, published on November 4, 2026, are based on data from more than 3.2 million adolescents across 140 countries and territories. They show that the average number of days of physical activity does not exceed 2.7 per week, with only 14 percent of adolescents being active daily.
The danger of these figures lies not only in the scale of the phenomenon but also in its potential impact on future health. Physical inactivity is associated with an increased risk of heart disease, type 2 diabetes, and certain types of cancer, while adolescence is a critical period for developing healthy habits that can last throughout a person's life.
The data reveal a notable difference between girls and boys, with 28 percent of girls recording no active days, compared to 22 percent of boys. This gap raises questions about the availability of safe spaces, sports opportunities, and the social factors limiting their participation.
Notably, activity levels have not improved significantly over the past 15 years, indicating that the problem cannot be attributed solely to a lack of will among adolescents. It is also linked to the school and urban environment, transportation options, and access to safe spaces for sports and walking.
Addressing inactivity, therefore, requires more than individual advice. It also calls for educational, health, and municipal policies that make physical activity a natural part of daily life.
Protecting the health of the next generation starts not when illness appears, but with the spaces and opportunities that enable them to prevent it.
