When students recognize they might have mental problems such as stress, depression, or anxiety, they should ask for help or find a way to deal with these problems. A variety of resources exist out there to help students deal with these mental problems. Students can go to schools’ wellness centers to talk with counselors; they have professional knowledge, so they might provide the best advice to students. The gym is the most popular place where students can “sweat” out their stress or pressure; moreover, exercise is a great way to refresh students’ brains so that they can learn more effectively. According to the article, students who want to shift their focus for a while should make time for their hobbies (Ponton, 2014). Another great way for students to reduce stress is through conversation with family or friends. Most of the time, students’ stresses result from their family’s high expectations or friends’ “competition.” Therefore, family or friends might help students deal with these problems. Students who think they need to reduce their stress should really find a way to do so, or they will develop more serious mental illnesses.
