Stress is a condition characterized by symptoms of emotional or physical tension that is caused by stressors, which can be internal or external factors. A 2018 study found that rates of anxiety and depression had increased in children ages 6-17 years old from 2003 to 2011-2012. Signs of stress include irritability, changes in behavior, trouble sleeping, neglecting responsibilities, eating changes, and getting sick more often. Managing stress involves taking deep breaths, eating healthy, exercising regularly, getting plenty of sleep, and avoiding excessive substance use. It's important for people struggling with stress to seek help from friends, adults, or teachers.
