COVID-19 is a disease that has wreaked havoc in all walks of life because of its high mortality and the political, social, psychological, educational, and economic consequences (Martínez, 2020). The loss of life will result in a more severe mental health crisis in patients, their families, communities, and health care workers (Omary, 2020). The COVID-19 pandemic has many elements that make it exceptionally stressful for students (Besser et al., 2020). Numerous factors may account for the increased risk to students in higher education, the mental health problems the pandemic may bring, the loss of important commencement and completion rites (Gruber et al., 2020). Studies conducted explicitly on college students in China reflect the high possibility of experiencing, witnessing, or facing various stressful events related to the occurrence of COVID-19, which resulted in negative psychological symptoms, such as feeling tense, fear of infection, insomnia, and low mood (Yang et al., 2020). Students who experience increased social isolation due to COVID-19 may have a higher risk of increased psychological distress (Hamza et al., 2020).

In non-pandemic time students face experiences that can be physically, emotionally, and psychologically challenging (Cushman & West, 2006). Despite the widespread prevalence of psychological distress affecting many students in higher education, the research on student stress remains largely theoretical (Williams et al., 2018). Students often experience high levels of stress and burnout (Humphrey, 2013). Stress often leads to burnout, which can seriously jeopardize a student's college experience (Schaufeli et al., 2020).

Burnout plays a fundamental role in students' lives (Cushman & West, 2006). In numerous works, the three dimensions of burnout syndrome have been studied: emotional exhaustion, depersonalization, and lack of personal fulfillment (Ramos et al., 2005).

Emotional exhaustion is a significant problem among higher education students and a public health problem in general (Tlili et al., 2020). Emotional exhaustion or burnout alludes to the situation in which people feel that they can no longer give more of themselves on an affective level; it is a situation of depletion of one's energy or emotional resources (Marrau, 2004). The problem of emotional exhaustion among adolescent and college students has recently gained broader prominence in national education policy in many countries (Galbraith & Merrill, 2015). More than one-third of college students experience detrimental imbalances between the effort they put into their studies and the rewards they get in return (Williams et al., 2018). The consequences of emotional exhaustion in students are as complex as other factors of mental distress, such as those related to smoking and alcohol consumption or an unhealthy lifestyle (Tlili et al., 2020). Contextual burnout can also extend to depression (Al-alawi et al., 2017) and anxiety (Farrell et al., 2019), internet dropout and addiction, and compromise with overall life satisfaction and success in educational pathways (Salmela-aro, 2017). In addition, there might be consequences such as dropout, sleep disorders, depression, and suicide (Pagnin et al., 2020) and even symptoms associated with posttraumatic and dissociative stress (Boudoukha et al., 2017). The use of drugs and alcohol to reduce stress is of concern (Erschens et al., 2018). A student's level of burnout directly impacts that student's level of efficiency and productivity (Galbraith & Merrill, 2015). It also increases their intention to withdraw from college (Williams et al., 2018). A student with high burnout may study the same amount of hours as a student with low burnout but may not be as productive due to the various emotional, behavioral, cognitive, and physiological reactions caused by burnout (Galbraith & Merrill, 2015).

Given the importance of emotional exhaustion and its possible repercussions on students' mental health and performance, it is necessary to determine the presence of this phenomenon and its potential consequences on the mental health of social science students in Chilean higher education during the COVID-19 pandemic.

Table 2 shows the sociodemographic characteristics of the students of the various social science majors, which are distributed as follows:

Table 3 shows the perception of students in the social sciences concerning their mental health: 284 (90.2%) reported that their mental health has worsened, 202 (64.1%) reported stress symptoms, 124 (39.4%) irritability, 129 (41%) increased sensitivity, 125 (39.7%) anguish and/or anxiety, 110 (34.9%) depressive symptoms.

Table 4 shows that among the factors that most affected social science students were the pandemic (61.9%), confinement and social distancing (47.3%), economic problems (41.6%), and news and media about COVID-19 (23.8%).

Table 5 shows that the careers that belong to the area of social sciences present high levels of emotional exhaustion. Psychology high (59.9%), medium (34.6%) low (5.6%); Law high (74.2%), medium (21.5%) low (4.3%); Social Work high (70.2%), medium (25.5%) low (4.3%); Political Science high (100%); Sociology high (37.5%), medium (50%) low (12.5%).

This research shows the pandemic's complexity on the mental health of higher education students, generating a high level of emotional exhaustion. The perception of social science students is that more than 90% of them consider that their mental health has worsened in the period of the COVID-19 pandemic and that the main reason has been the COVID-19 pandemic with 61.9%. These findings are consistent with other findings that the general perception of higher education students is that their mental health has been impaired, even more so in students who had pre-existing mental illnesses before the pandemic (Banerjee, 2020; Hamza et al., 2020). This can lead to severe psychological decompensation (Y. Sun et al., 2020). It is increasingly evident that the pandemic confers serious and potentially complex long-term mental health consequences (Gruber et al., 2020).

More than 65% of the students presented high emotional exhaustion in our research. This refers to the situation in which people feel that they can no longer give more of themselves at an affective level; it is a situation of depletion of energy or emotional resources (Marrau, 2004) with consequences such as feelings of abandonment, sleep disorders, depression, and suicide (Pagnin et al., 2020). This emotional exhaustion may be due to the high demands of studies, cynical and distant attitudes towards their studies, and feelings of academic incompetence (Schaufeli et al., 2020). They have increased during the pandemic of COVID-19, given the changes from face-to-face to online study, which generates great wear to be in front of a screen without greater environmental stimulation. Therefore it is necessary to continue studying how the transition from face-to-face to online classes affects mental health since such a sudden transition could have harmful consequences for students (Besser et al., 2020; Gurung & Stone, 2020), especially for those in vulnerable situations. These interruptions can be especially traumatic (Lancaster & Arango, 2021). Therefore due to the global pandemic of COVID-19, students now face new and unprecedented challenges (e.g., significant academic changes and interruptions, stay-at-home orders, etc.) (Hamza et al., 2020).

Within our research, it can be observed that social science students perceive that 64.1% of them would present symptoms of stress. The above correlates with other analysis where perceived stress has increased, generating physical consequences and sleep disorders (Lancaster & Arango, 2021). These results are of concern given that a recent review strongly correlates stress with increased alcohol consumption (Acuff et al., 2021) and is associated with increases in anxiety and fear of getting sick (Danzi et al., 2021), as well as increases in emotional exhaustion (Chan et al., 2021). The degree of stress and adversity that people experience due to COVID-19 depends on economic, social, and health factors (Lancaster & Arango, 2021). As presented in our study, 41.6% of the students refer that financial problems have affected them, which could lead to relevant psychological issues given the insecurity that has brought the virus and the economic stability in general (Marler et al., 2021).

The perception of the presence of depressive symptoms and irritability reported by students in the social sciences was 34.9% and 41%, with greater sensitivity, which is in line with other studies in which they say that depressive symptoms are in the order of 20% to 30% in university students (Wang et al., 2020). The findings support the primary hypothesis that the prevalence of probable moderate to severe depression, self-harm, suicidal ideation, and emotional distress due to COVID-19 was significantly higher among quarantined participants than non-quarantined participants (Xin et al., 2020).

In our study, more than 39% of the students reported presenting anxiety and/or distress symptoms, which is consistent with other research where 20% to 35% of the respondents reported anxiety and over 25% reported high levels of stress after the onset of the outbreak (Cao et al., 2020; Huang & Zao, 2020). Furthermore, the findings corroborate the interaction between ongoing pandemic-related stress and fear of COVID-19 (Chan et al., 2021). This can be associated with our results: 61.9% of students refer the pandemic itself had affected their mental health the most and that 23.8% of students felt that the news had affected them. Along these same lines, 47.3% of students identified that confinement and social distancing had affected them. In particular, young adult college students may be a population vulnerable to psychological distress during quarantine (S. Sun et al., 2021). A recent meta-analysis of 25 empirical studies found that those in quarantine were more likely to be anxious (odds ratio, OR) (OR = 2.0) and depressed (OR = 2.8) (Henssler et al., 2021). This may lead to increased suicidal thoughts and ideation (Martínez-Líbano & Yeomans Cabrera, 2021; Pandey et al., 2020). However, other research has shown that wellbeing was not affected by concern about the consequences of the virus. Although respondents showed some fear of infection and severe illness in someone in their networks and had doubts about the efficiency of medical care, these factors did not negatively affect their wellbeing (Lukacs, 2021).

Addressing the consequences of emotional exhaustion is necessary to preserve good mental health, which can be defined as a state of wellbeing that enables people to cope with life's everyday stresses and function productively (Fusar-Poli et al., 2020). Findings have consistently demonstrated the importance of psychosocial factors and mental health in the academic success of college students (Kivlighan et al., 2020). Psychological problems, such as depression and anxiety, are common among students (Kim et al., 2015). College students have long-standing mental health conditions and suicide risks (McLaughlin & Gunnell, 2020).

It is essential that the authorities address this issue and urgently seek solutions to mitigate the psychological impact of home confinement (anxiety, stress, depression, frustration, among others) (Yeomans & Silva, 2020). Universities have a responsibility to advocate for students, especially for those students who are vulnerable (Benner et al., 2018). Fostering resilience is a promising way to mitigate the adverse effects of stressors, prevent burnout and help students thrive after difficult experiences (Houpy et al., 2017).

The COVID-19 pandemic has profoundly impacted the mental health of social science students, generating a high level of emotional exhaustion. In this research, 90.2% of the students reported that their mental health has worsened, developing stress, irritability, anxiety, anguish, and depressive symptoms. This is mainly caused by the pandemic, confinement, economic problems, social distancing, and the news. Concerning emotional exhaustion in the students, these presented high (65.7%), medium (29.2%), and low (5.1%). These results should call the attention of government authorities and higher education institutions since the mental health of university students is fundamental. They will be the future professionals to lead our society, so possible adverse consequences should be addressed to mitigate harmful potential implications for our community.
