There are several causes of the college student mental health crisis. Living in a new environment, feeling unprepared for the rigor of college-level courses, pulling all-nighters to study for an exam or finish a paper, having to juggle a job to pay for living expenses, experiencing homesickness or loneliness, binge-drinking—each of these individually can be problematic. Combined, they create the perfect storm for a mental health crisis on college campuses.
Research suggests another reason for the college student mental health crisis is simply that the age at which many mental disorders manifest is between 18 and 24, which aligns with the ages of most students in college
According to a Psychology Today article, these less obvious reasons could also be contributing to the problem:
Sexual abuse. Students who have been sexually abused in the past deal with lingering bad memories and self-esteem issues that often lead to mental health concerns if not treated.
Information overload. The rapid evolution of technology, information overload, and an environmental mismatch can overwhelm the student's mind. The last few years have seen an unprecedented acceleration of technology and social change that has altered the social fabric and how people relate.
