Introduction:
The time spent in college is a transitional stage, where students face a change of adaptation to a social environment, to the load and academic pressure and excessive demands. Currently the presence of disorders such as anxiety, stress and depression are more common in higher education communities, due to academic and work demands, especially when trying to reintegrate into life after the pandemic by COVID-19 and maintain a state of psychological, social and emotional well-being today, has become a challenge for students, families and teachers.
Psychological disorders tend to interfere with professional and academic development, as well as influence the emotional state, hindering the university and psychosocial process.
Higher education students are at high risk of suffering mental health disorders related to academic demands, financial situation and social interaction, making it difficult for them to carry out their daily activities and therefore affecting their academic performance.
Undoubtedly, another challenge has been to reintegrate to face-to-face education with psychoemotional damage, therefore, this paper addresses the impact of stress disorders, depression and anxiety in university students. Academic stress is considered as an adaptive and psychological process that can occur when the student is subjected to demands valued as stressors that produce a systemic imbalance manifesting itself through a series of symptoms that force students to opt for some coping measures to restore the systemic balance.
