South Korean Study Links Teen Exercise to Lower Depression and Loneliness

Regular physical activity supports teenage physical growth, mental well‑being and healthy habits, according to health experts. A Korean research project examined 920 middle‑ and high‑school students and 911 adolescents from 15 schools. The studies found that teenagers who exercised at least one hour a day were less likely to be classified as depressed (11 % versus 17.9 % among less active peers) and were 1.3 times less likely to experience high loneliness. Physical activity also weakened the link between parental psychological aggression and loneliness, and reduced the gap in smartphone‑addiction rates, especially among girls (37 % vs 32.8 %). Researchers said the findings highlight the protective role of exercise against academic stress, emotional abuse and digital overuse, and urged schools and policymakers to ensure sufficient time for daily physical activity.

The broader health literature notes that weight‑bearing and aerobic exercise improves bone density, cardiovascular fitness, mood, sleep and self‑confidence, reinforcing the importance of encouraging teens to find enjoyable activities that fit their interests and schedules.
