Abstract: Growing academic and career pressure, along with increasingly sedentary lifestyles and excessive use of digital devices, has led to a noticeable rise in overthinking, anxiety, and depression among students. Research shows that regular and structured exercise can play an important role in improving mental well-being, enhancing cognitive performance, and maintaining emotional balance.This narrative review brings together existing literature on student mental health and highlights practical approaches for improvement. Mental health issues are now widely seen across all levels of education, from school to higher studies, and are becoming a serious concern. The paper focuses on the role of physical activity and exercise therapy in managing common problems such as anxiety, depression, and cognitive fatigue. Based on current findings from neuroscience and psychiatry, it suggests that exercise should be considered not just a physical activity, but an essential part of mental health support within the educational system.

INTRODUCTION
Different mental health issues among students are increasing globally. There is an academic and study pressure, social pressure, expectations, and reduced physical activity contribute to poor psychological outcomes. Physical activity has emerged as an effective, low-cost, and accessible intervention. This study reviews evidence supporting the role of the exercises in relation with psychological outcomes.Students are navigating a transition from traditional learning to AI-integrated environments. While intellectual demands have scaled, physical movement has reached a lowest level.(1)
The correlation between sedentary behaviour and psychological distress is no longer speculative. There are the longitudinal studies suggests that students spending more than 7 to 8 hours per day in sedentary positions are 45% more likely to report symptoms of clinical depression(4). This manuscript argues that Exercise Therapy (ET) must transition from an "hobby" to a fundamental clinical need within the educational framework.(1)
The landscape of global higher education is currently grappling with a dual-crisis: a precipitous rise in clinical mental health diagnoses and an increasingly sedentary lifestyle fostered by the digital revolution. As we move through 2025, the "student experience" has been fundamentally restructured by digital learning interfaces, AI-driven research tools, and a hyper-competitive global labour market. While these advancements have increased cognitive output, they have simultaneously decoupled the human mind from its requirement for physical movement.(2)Recent data suggests that nearly 60% of school students meet the criteria for at least one mental health problem, with anxiety and depression leading the increase in the statistics of psychological issues. The traditional "talk therapy" and pharmacological models, while effective, are currently overwhelmed by sheer volume. This gives a necessityto shift toward lifestyle medicine, specifically the integration of Physical Activity (PA) and Exercise Therapy (ET) as frontline defenses in student wellness(3)
A profound paradox exists within modern academics: students often ignore physical movement in the pursuit of cognitive performance. The prevailing "grind culture" suggests that time spent in the gym or on the track is time diverted from the library. However, contemporary neuroscience reveals the opposite to be true. The brain is a biological organ that thrives on the metabolic byproducts of physical exertion.The transition from secondary to tertiary education represents a "high-risk" window for the cessation of regular exercise. As academic pressure increases, physical self-care often decreases, creating a feedback loop of:Increased Cortisol levels: From chronic academic stress, Physical Inactivity- Leading to poor sleep and reduced neurogenesis and Cognition Decline: Resulting in further stress and diminished mental health.(4)
Higher education systems across the world are currently facing a serious challenge related to student well-being. Recent data from 2025 shows that nearly 60% of university students experience symptoms of anxiety or depression, reflecting a significant increase compared to the past decade. This trend is largely linked to rising academic demands, reduced physical activity, and increasingly sedentary daily routines.Although traditional approaches such as Cognitive Behavioural Therapy (CBT) and medication continue to play an important role in managing mental health conditions, they are often used after problems have already developed rather than preventing them in the first place.
While traditional psychological interventions—such as Cognitive Behavioural Therapy (CBT) and pharmacotherapy—remains important, they are often reactive rather than prophylactic. Physical Activity (PA) and Exercise Therapy (ET) represent a patterned shift: a non-pharmacological, cost-effective, and biologically intervention that addresses both the physiological and psychological roots of student distress.(5)
From an evolutionary perspective, the human brain developed in an environment of constant movement.The Cognitive-Functional Hypothesis proposes that key executive functions such as memory, attention, and emotional control work more effectively when the body is physically active. In contrast, when students lead a sedentary lifestyle, there is a reduction in important neurotrophic factors. This can result in symptoms like mental fatigue or “brain fog,” shorter attention span, and difficulty in managing stress, partly due to poor regulation of the Hypothalamic-Pituitary-Adrenal (HPA) axis.(8)

The existing literature on the dose–response relationship between exercise and student mental health reveals three significant conclusions. Initially, from a neurochemical standpoint, research consistently demonstrates that even brief exercise sessions, typically lasting 30 minutes or more, can elevate Brain-Derived Neurotrophic Factor (BDNF) levels. This protein is crucial for neurogenesis within the hippocampus, a brain region implicated in memory and emotional regulation, which frequently suffers in students facing chronic stress. Secondly, distinct exercise modalities seem to confer specific psychological advantages. High-Intensity Interval Training (HIIT), undertaken approximately twice weekly, is linked to a swift decrease in depressive symptoms and exhibits a substantial effect size (Cohen’s d = 0.82).Mind–body interventions such as yoga or mindfulness-based exercise, practiced three times per week, are particularly effective in reducing generalized anxiety, with a moderate effect size (d = 0.65). Similarly, resistance training carried out three times per week has been linked to improvements in self-esteem and body image, also demonstrating a moderate effect (d = 0.55).
Finally, there is a strong association between physical activity and academic performance. Students who meet the World Health Organization recommendation of at least 150 minutes of moderate physical activity per week tend to achieve higher academic outcomes. On average, they show about a 12% higher GPA compared to their sedentary peers, which may be attributed to better executive functioning and improved sleep quality.
DISCUSSION
The findings of this review clearly indicate that physical activity and structured exercise therapy are not just supportive lifestyle choices, but essential biological interventions for maintaining and improving student mental health. The current academic environment places students under continuous cognitive and emotional pressure. When this is combined with physical inactivity, it creates a negative cycle that affects both brain function and overall psychological well-being.
One of the key mechanisms involved is the role of Brain-Derived Neurotrophic Factor (BDNF). Regular exercise has been shown to increase BDNF levels, which supports neurogenesis, particularly in the hippocampus. This area of the brain is closely linked with memory, learning, and emotional regulation. In students exposed to chronic academic stress and peer pressure, hippocampal function may decline. However, consistent physical activity helps counteract this effect by promoting neural regeneration and improving synaptic plasticity.
Exercise also plays an important role in reducing systemic inflammation. It helps lower pro-inflammatory markers such as interleukin-6 (IL-6), which are commonly associated with depression, anxiety, fatigue, and reduced cognitive efficiency. By decreasing inflammation, exercise improves attention span, processing speed, and overall mental clarity. This is often experienced by students as a sense of improved focus or “mental clearing” after physical activity.
Another important finding is the dose–response relationship between exercise and mental health outcomes. Moderate-intensity exercise performed for at least 30 minutes per session leads to noticeable improvements in psychological well-being, including reduced symptoms of anxiety and depression. Different forms of exercise offer specific benefits. High-Intensity Interval Training (HIIT) is particularly effective in reducing depressive symptoms. Mind–body practices such as yoga and meditation are beneficial for lowering anxiety and improving autonomic balance. Resistance training, on the other hand, contributes to better self-esteem, body image, and emotional resilience.
These findings suggest that exercise interventions should not follow a one-size-fits-all approach. Instead, exercise programs should be tailored to the individual needs of students based on their psychological concerns. The review also highlights a strong relationship between physical activity and academic performance. Students who meet recommended physical activity guidelines tend to demonstrate better executive functioning, improved sleep quality, and higher academic achievement. This challenges the common belief that time spent exercising reduces study time. In reality, exercise enhances learning efficiency, allowing students to study more effectively.
Despite these well-established benefits, lack of time remains one of the most commonly reported barriers. Many students view exercise as a non-essential activity and prioritize academic work instead. This perception overlooks the role of exercise as a cognitive enhancer. There is a clear need for a shift in mindset, where physical activity is seen as a necessary part of academic success rather than a distraction.
Institutional support is crucial in addressing this issue. Educational institutions should adopt structured strategies such as incorporating exercise into daily routines, promoting active campus environments, and introducing the concept of “exercise prescriptions.” Simple changes like walkable campuses, standing study areas, and scheduled activity breaks can encourage students to stay active.
In addition, the concept of “green exercise,” or engaging in physical activity in natural environments, has shown greater psychological benefits compared to indoor exercise. Exposure to nature is associated with faster mental recovery, reduced stress, and improved mood, suggesting that environmental factors also play a role in enhancing the effectiveness of exercise.
From a practical perspective, exercise can be strategically used to improve academic performance. By reducing inflammation and enhancing neural efficiency, it may be beneficial for students to schedule demanding study sessions after physical activity. However, the major barrier remains the perception of limited time. This review emphasizes that even 30 minutes of exercise should be viewed as a high-value investment in cognitive performance rather than time lost.
In summary, this discussion reinforces the idea that physical inactivity is not just a lifestyle concern but a critical factor contributing to declining mental health among students. Exercise therapy offers a very cost-effective, accessible, and scientifically validated solution that addresses both physiological and psychological aspects of well-being. Integrating structured physical activity into the academic ecosystem is no longer optional—it is a necessary step toward developing cognitively efficient, emotionally resilient, and academically successful individuals. The results confirm that Exercise Therapy is not merely "good and requirement for health" but is a biological necessity for cognitive survival. The discussion emphasizes the "cognitive clearing" that occurs post-exercises. Physical activity increases the expression of Brain-Derived Neurotrophic Factor (BDNF), a protein essential for neurogenesis in the hippocampus
CONCLUSION
Physical Activity and Exercise Therapy are the most underutilized tools in modern education. The evidence suggests that a sedentary student is a cognitively compromised student.
LIMITATIONS
Current research often relies on self-reported data regarding exercise frequency, which may lead to social desirability bias. The concept of “green exercise,” which involves physical activity in outdoor settings, shows promising benefits compared to indoor exercise. However, there is still a need for more long-term studies, especially within urban campus environments, to better understand its sustained impact on student mental health.
Several key recommendations emerge from this review. Universities should consider introducing “exercise on prescription” as part of their student health services. In addition, campus environments should be designed to promote movement through features such as walkable pathways, standing study areas, and active learning spaces. It is equally important to educate students about the neurobiological benefits of exercise, helping to challenge the common misconception that physical activity interferes with academic performance.
By creating a culture where movement is seen as essential for mental clarity, institutions can develop graduates who are not only academically competent but also emotionally resilient and better prepared to handle future challenges.
