Reports indicate various health and lifestyle risks affecting adolescents globally. In Spain and Mexico, concerns have been raised regarding sleep patterns and substance use. In Asturias, Spain, 19% of teenagers aged 14 to 18 have used hypnosedatives to aid sleep, with one in three students experiencing daytime drowsiness. In Saltillo, Mexico, data shows that individuals aged 15 to 19 are the demographic most affected by alcohol and substance abuse.

Individual cases further illustrate these risks. In Vietnam, a 15-year-old student required treatment for non-suicidal self-injury linked to academic pressure, social media use, and insomnia. In China, a 15-year-old girl died from late-stage colorectal cancer; medical professionals noted the illness was linked to poor dietary habits and a reliance on food delivery apps, compounded by the patient ignoring symptoms to avoid parental reprimand.
