A Healthy Mind Makes a Healthy Body in Teens - Science Daily Happier youths are also healthier youths, according to Emily Shaffer-Hudkins and her team, from the University of South Florida in the US. Adolescents' positive emotions and moods, as well as their satisfaction with life, could be more important than their anxiety or depression levels for predicting their physical health, they argue. Looking at teenagers' so-called 'subjective well-being' could help identify those likely to develop health problems in the future and target them with appropriate prevention strategies. Overall, perceived good physical health was strongly linked to life satisfaction and feeling excited, strong and proud. Those who said they felt lonelier, guiltier, more anxious and depressed and who were more likely to display undesirable behaviors reported being less healthy physically. More specifically, mental health indicators explained 30 percent of the difference in physical health ratings and four out of the five mental health indicators were unique predictors of physical health. Positive affect in particular had the greatest effect.
