Introduction 

Did you know that the combination of Cognitive Behavioural Therapy (CBT) and exercise can significantly improve mental health? Since its development, CBT has become a well-researched and adaptable treatment for various psychological issues, including anxiety and depression. In this article, we delve into the crucial connection between CBT and exercise, exploring recent studies that highlight the transformative impact of this combination on reducing anxiety and enhancing overall quality of life. We aim to provide insights into the wide-ranging applications of CBT beyond anxiety and depression. 

Overview

Cognitive Behavioural Therapy ( CBT) is a research-supported treatment for different psychological problems and disorders. Since the 1960s when Aaron Beck developed this type of therapy, its effectiveness has been profoundly analysed and adapted for distinct groups of people.1 Currently, CBT is a summary of years of scientific research on the mind and what makes us feel better. Let’s take a precise look at it. But before that, how about the question in the title? What is the connection between CBT and exercise? A recent study conducted on pregnant women shows that a combination of therapy and exercises can effectively reduce anxiety and drastically improve the quality of life.² This signifies the importance of CBT in improving everyday life.  

When can CBT be used?

The main areas where it is used are anxiety and depression. However, there are many more problems that can be solved by using techniques from CBT, such as bipolar disorder, borderline personality disorder, eating disorders, obsessive compulsive disorder, panic disorder and phobias, post-traumatic stress disorder (PTSD), psychosis, schizophrenia and insomnia. What is more interesting is that CBT can be also used in some long term conditions. For example, chronic pain, chronic fatigue syndrome, irritable bowel syndrome. Unfortunately, for these long term conditions it can only help to cope with symptoms better.^4,5,6

So, what exactly is done during CBT? 

CBT interventions use exercises and skills to reduce psychological tension in previously mentioned psychological problems. It helps to understand difficult situations and negative reactions to them. 

In cognitive behavioural therapy (CBT), these aspects are emphasised: 

• Core beliefs (schemas), which are deeply rooted childhood experiences
• Dysfunctional assumptions or in other words irrational thought patterns that can even change perception of the world
• Negative automatic thoughts, which appear out of habit³

Psychological problems often revolve around three central elements: thoughts, emotions, and behaviour. Deconstructing emotions enables individuals to comprehend the preceding thoughts and the reasons behind their actions in any given situation.

In order to deal with these aspects CBT offers some techniques. They are cognitive restructuring, behaviour modification and goal setting. 

Cognitive restructuring

As you might already catch from the previous information, cognitive theory suggests that our emotions and behaviours are influenced more by how we think about a situation than the situation itself. Therefore, cognitive restructuring is a technique where we identify and examine unhelpful thoughts that lead to emotions like anxiety and unhappiness. Simultaneously, we work on developing and reinforcing more helpful thoughts.⁷

Behavioural modification

It is a type of therapy used to help people, both kids and adults, reduce or eliminate unwanted behaviours. Unlike some therapies that focus on changing thoughts, behaviour modification concentrates on changing specific actions without delving much into thoughts or feelings. This approach is practical because progress and outcomes can be measured and assessed.

Here is how it works:

1. Identify the problem: First, understand the causes and effects of the troublesome behaviour
2. Choose targets: Determine the specific behaviours to address in therapy
3. Use reinforcement and punishment: Adjust factors, like rewards or consequences, to encourage positive changes

In the realm of mental health, behaviour therapy accomplishes goals that medication alone might not. It creates lasting changes in individuals, even after the formal therapy ends.⁸

Goal setting 

It helps individuals pinpoint specific behaviours to change and outlines the steps to do so. Two crucial strategies to assist in setting and achieving goals: considering key goal characteristics and creating action plans. Setting goals and creating action plans are valuable steps, but they alone cannot guarantee behaviour change. Volitional action is crucial.⁹

Exercise and mental health 

Now returning back to the second part of the topic. Physical activity not only contributes to physical health but also has significant positive effects on mental well-being. Exercises have substantial effects on self-concept and body image, crucial components of mental well-being. While exercise influences depression and anxiety, the impact is more pronounced in clinical patients. Regular physical activity enhances the functioning of the hypothalamus-pituitary-adrenal axis, contributing to mental health improvement. Numerous psychological benefits, including enhanced mood, self-esteem, cognitive function, and overall quality of life, have been associated with exercise. 

Moreover, exercise triggers the production of opioids and endocannabinoids, linked to pleasure, reduced anxiety, improved sleep, and pain sensitivity. Regular physical activity is linked to improved attention, focus, memory, cognition, language fluency, and decision-making, lasting for up to two hours. Also, depression can be effectively managed with regular physical exercise. The endorphin hypothesis suggests a link between exercise, endorphin, hormone that makes you feel good, releases, and improves your mood.¹⁰

Types of exercises and their mental health benefits

Aerobic exercises

The examples are jogging, swimming, cycling, walking, gardening, dancing. The aim for the aerobic exercises are to reduce anxiety and depression and boost wellness. These exercises are associated with an improved mood achieved through increased blood circulation to the brain. They influence physiological stress sensitivity and establish communication with essential brain regions, including the limbic system for mood control, the amygdala for fear response, and the hippocampus for memory and motivation.¹¹ Another study demonstrated the positive impact of aerobic exercise training on the mental health and self-esteem of individuals with type 2 diabetes mellitus.¹³

The study suggests that regular aerobic exercise can play a crucial role in enhancing self-esteem and mental health among individuals with type 2 diabetes mellitus. The increased self-esteem score after the intervention aligns with previous research emphasising the positive relationship between exercise and self-esteem. Physical exercise has been linked to improved mental health and well-being, and this study supports the idea that aerobic exercise can significantly impact mental health and self-esteem in individuals with type 2 diabetes mellitus. The findings highlight the importance of incorporating regular aerobic exercises. 

Strength training

While the mental health benefits of regular exercise are widely acknowledged, the role of resistance exercise, commonly known as strength training, in mental well-being has garnered less attention. Resistance exercise involves various procedures challenging muscles against resistance beyond daily activities. It encompasses a range of activities utilising equipment like elastic bands, free weights, or resistance machines, performed in sets with specific repetitions.

Research has consistently shown that resistance training at a low-to-moderate intensity leads to significant and reliable decreases in anxiety.¹² Unlike higher intensities, these sessions demonstrate acute anxiolytic effects. Notably, studies suggest that exercise can induce anxiety reduction. Gender differences also play a role, with females exhibiting more sensitivity to the anxiolytic effects of resistance exercise than males.

For sustained benefits in clinical populations, the intensity of resistance exercise remains crucial. Long-term resistance training studies, particularly in older populations, reveal that low-to-moderate intensities consistently produce greater decreases in anxiety than higher intensities. Resistance exercise appears effective across various age groups, including middle-aged and post-menopausal individuals. 

Mind-body exercises

Mind–body exercises encompass a unique approach to physical activity, emphasising the integration of mental and physical elements. Unlike conventional exercises focused solely on muscular strength, mind–body exercises, such as Tai Chi and Yoga, combine slow voluntary movements, full-body stretching, diaphragmatic breathing, meditative states, and mental concentration.

Originating in China and India, respectively, Tai Chi and Yoga are widely practised globally by people of all ages and health conditions. Studies delve into the long-lasting effects of Tai Chi and Yoga on heart parameters and perceived stress.¹⁴ The study suggests that engaging in as little as 60 minutes per week of Yoga may yield beneficial effects on heart rate modulation and stress reduction. While findings for Tai Chi are inconclusive due to fewer studies and methodological limitations, the study underscores the potential of both Tai Chi and Yoga as accessible methods for stress reduction.

These mind–body exercises offer an alternative approach to promoting well-being by harmonising mental and physical aspects, making them valuable tools for individuals facing high stress or negative emotions. 

What is behind mental health benefits of exercises?

So, why exactly does it benefit? We checked benefits on biological and hormonal level, but how is it beneficial on the social level? Engaging in physical activity provides a healthy distraction from stressors. Exercise fosters a sense of accomplishment and self-efficacy. Participating in group programs can enhance social interaction, contributing to improved mental well-being. Accumulating and increasing moderate-intensity activity throughout the day is a practical approach for most people. Physical activity interventions show comparable adherence rates in psychiatric patients as in the general population.¹¹

Integration of CBT and exercise

Combining exercise with behavioural therapy has shown promising results. 

Two studies shed light on the effectiveness of such integrated approaches. First study focused more on investigation of the impact of a combined exercise and cognitive-behavioural intervention on the mental health of young men.¹⁵ Both cognitive-behavioural therapy and exercises significantly reduced depression scores compared to the control group, with exercises showing greater perceived social support. The findings underscore the potential of exercise-based interventions for improving mental well-being in young men.

Another study focused on the combined effect of exercise and behavioural therapy for depression and anxiety.¹⁶ It demonstrated a significant reduction in depression symptoms. Moderate exercise intensity and elevated baseline depression levels were associated with better outcomes. The study emphasises the potential of exercise as an adjunct treatment for depression, especially when tailored to individual needs. Both studies contribute valuable insights, highlighting the efficacy of combining exercise with behavioural therapy for mental health. Integrative approaches like these hold promise for addressing a spectrum of mental health challenges, providing a more holistic and personalised approach to treatment.

Summary

In summary, the combination of Cognitive Behavioural Therapy (CBT) and exercise proves to be a powerful ally in improving mental health. CBT, originating in the 1960s, has evolved into a well-researched therapy, effective for various mental health issues like anxiety, depression, and more. Recent studies, particularly focusing on pregnant women, highlight the positive impact of integrating therapy and exercise, leading to reduced anxiety and an enhanced quality of life.

CBT extends its benefits to conditions beyond anxiety and depression, including bipolar disorder, eating disorders, PTSD, and chronic pain. Its core interventions target fundamental beliefs, irrational thought patterns, and automatic negative thoughts, unravelling the complex connections between thoughts, emotions, and behaviour. Techniques such as cognitive restructuring, behavioural modification, and goal setting prove effective in alleviating psychological tensions.

The inherent connection between physical activity and mental well-being further underscores the potential for holistic mental health interventions. Aerobic exercises, strength training, and mind-body exercises like Tai Chi and Yoga offer distinct benefits, from improved mood to anxiety reduction. These exercises positively impact biological, hormonal, and social levels, contributing to better sleep, stress relief, enhanced mood, and increased social interaction. The integration of CBT and exercise reveals a new dimension in mental health treatment.

Two enlightening studies support the effectiveness of this combined approach, demonstrating significant reductions in depression symptoms and increased perceived social support. The synergy of CBT and exercise holds promise in addressing diverse mental health challenges, offering a personalised and comprehensive strategy for individuals seeking lasting well-being. As we explore the intricate interplay of mind and body, the potential for transformative mental health interventions continues to expand, providing hope and healing for a brighter future.
