According to data collected by the American Psychological Association for the Stress in America Survey , teen stress rivals that of adults. Results of the survey show that not only do teens identify that their stress levels are not healthy, but they also underestimate the impact stress has on their mental and physical health. All teens experience some amount of stress, and some stress can even be healthy. Many teens, however, struggle with significant stress levels that interfere with learning, relationships, and other areas of functioning. Stress can manifest in different ways, and some symptoms of stress mimic normal teen behavior. To that end, stress can sneak up on teens.
