Stress for a teenager is as real a problem as stress for an adult. To deal with it, it’s important to understand the causes of stress in teenagers.
When parents change their jobs or if the family decides to move to a different place, the child has to change schools, find new friends, adapt to the new social circle and fit into new groups. It is always difficult for children to adapt to such changes, which can be a serious cause of stress in their life.
Academic difficulties, such as inability to understand a certain subject can cause stress. Not every child has the ability to understand every subject. Some kids need extra help besides school work to grasp a few concepts. Poor academic performance is often laughed at and is looked down upon by both teachers and peers. In such cases, it can make the child feel isolated, neglected and hurt. All of this, put together, can add to stress, which many times worsens grades.
Extra curricular activities (课外活动) such as playing a sport, or attending art classes can weigh heavily on your child’s mind. Juggling between school and extra curricular activities does seem like a burden when you have to excel at both. When the pressures from both the ends get unmanageable, teenagers tend to get tired and annoyed. Fatigue sets in, leading to stress related issues such as lack of concentration in school.
These are the common causes of stress in teenagers, which can be noticed through signs such as poor memory, anxiety, negative and pessimistic attitude. If the signs of teenage stress go unrecognized for a long time, it can make the child emotinally imbalanced.
