Stress is not just a problem that adults have to face. Young people also frequently experience unhealthy levels of stress. Schooling is the top source which causes stress to teenagers. According to data collected by the American Psychological Association for the Stress in America Survey, teen stress is the same as, or even worse than that of adults. The results of the survey have shown that teenagers can identify that their stress levels are not healthy, and they realize that stress has negative impacts on their mental and physical health. Some teenagers can struggle against significant stress levels that interfere with learning, relationships, and other aspects in daily life; while other cannot get over the stress and have to get mental treatment. Therefore, it is important to know the negative effects that stress has on teenagers:
– Emotional changes: Teenagers tend to be easy to get anxious, worried, angry, and depressed. Parents should pay attention to their children’s changes in showing feelings.
– Physical changes: Teenagers who are under stress are likely to get sick more often and they often have complaints of headaches, stomachaches, other aches and pains.
– Behavioral changes: Teenagers may break their eating or sleeping habits. They seem to either eat enormously or quit meals. They suffer serious insomnia, which is a severe condition of being unable to sleep. They also show avoidance of normal daily activities.
– Cognitive changes: Teenagers who have stress notice their decreased concentration, forgetfulness, and the appearance of carelessness.
