Yoga Therapy for Depression: A Safe and Effective CAM Option

By Christine Saari, MA, C-IAYT and Sara Merrick-Albano, C-IAYT

Depression is a pervasive mental health disorder that impacts millions of people worldwide. While conventional treatments such as medication and psychotherapy are commonly prescribed, complementary and alternative medicine (CAM) therapies, like yoga therapy, have gained significant attention for their whole-person approach and efficacy in managing depression symptoms. 

This article explores how yoga therapy helps alleviate depressive symptoms, including its role in reducing IL-6 levels and inflammation. It also discusses yoga therapy’s role in addressing prenatal depression and co-morbid conditions like hypertension, cardiovascular disease, and anxiety. Additionally, we’ll examine the high acceptability rate and sustained effects of yoga therapy, and its advantages and disadvantages compared to other CAM therapeutic approaches.

Understanding Depression and The Role Of Complementary Treatments

Major Depressive Disorder (MDD) is characterized by persistent sadness, loss of interest or pleasure in activities, and a range of emotional, cognitive, and physical challenges. Effective treatments aims to achieve remission, reduce symptom severity, and prevent relapse.

Integrative approaches that combine medication, psychotherapy, and complementary and alternative medicine therapies, such as yoga therapy, can enhance treatment outcomes. Yoga therapy includes postures, movement, breathwork, mindfulness, affirmations, mantra meditation, health coaching, and spiritual practices tailored to a client’s beliefs. Research indicates that yoga provides benefits as an adjunct to traditional treatments for MDD, particularly in individuals who do not respond adequately to antidepressant therapy¹.

Physical activity also plays a crucial role in managing MDD, with studies highlighting a significant link between depressive symptoms and a sedentary lifestyle. Global recommendations now advocate incorporating physical activity interventions into standard psychiatric care to improve mental health outcomes².

Furthermore, individuals with depression often experience memory problems, including difficulties with updating working memory and task switching. Meditation practices, such as mindfulness and kindness meditation, have shown promise in enhancing memory recall and cognitive function during depression recovery^{(3, 4)}.

The Role of Inflammation and IL-6 in Depression

Interleukin-6 (IL-6) is a protein involved in inflammation and the immune response. Elevated IL-6 levels are commonly observed in individuals with depression and are linked to the severity and persistence of depressive symptoms⁵. IL-6 affects brain function by influencing neurotransmitter systems, such as serotonin, which regulate mood. High IL-6 levels can disrupt these systems, leading to symptoms like low mood, fatigue, and changes in sleep and appetite.

During stress, the body releases IL-6 as part of the immune response. In depressed individuals, this response is often heightened and prolonged, contributing to chronic stress and inflammation. This chronic inflammation can exacerbate depressive symptoms and impact brain function⁶.

Yoga Therapy and IL-6 Levels

Studies suggest that yoga therapy can effectively reduce IL-6 levels, thereby mitigating inflammation and improving depressive symptoms⁷. Moderate-intensity yoga exercises, in particular, have been shown to lower serum IL-6 levels, making them a beneficial component of depression treatment⁸.

Specialized Applications of Yoga Therapy for Depression

Yoga therapy’s approach consists of individualized practices for specific populations, such as prenatal care and individuals with cardiovascular health challenges. These contexts often require holistic, outcome-oriented approaches that address the multifaceted nature of symptoms and their impact on quality of life.

Prenatal Depression

Depression during pregnancy is a significant concern. Pregnant individuals often need to discontinue certain medications due to potential risks to the fetus, making CAM therapies a popular alternative.

Yoga therapy has shown promise in this area by providing a safe, non-pharmacological option for managing depression. A study by Gong et al. emphasizes the effectiveness of an integrated approach in treating prenatal depression⁹. Yoga therapy can reduce depressive symptoms, improve overall well-being, and foster a sense of empowerment, self-love, and support, all of which are crucial during this vulnerable period.

Managing Co-morbid Conditions

Depression frequently coexists with other mental health conditions such as anxiety¹⁰, and physical health issues including type 2 diabetes, metabolic syndrome, hypertension, and cardiovascular disease¹¹. Yoga therapy’s holistic approach is particularly beneficial here, as it addresses not only physical symptoms, but also underlying mechanisms such as autonomic nervous system (ANS) dysfunction¹², which has implications for both heart disease and depression^{(13, 14)}.

Yoga therapy is also an educational process, empowering clients with practical skills to effectively manage their symptoms, adapt to challenges, and prevent relapse. This approach ensures that individuals receive personalized care that considers their entire well-being, focusing on both the physical and emotional aspects of their health.

Efficacy of Yoga Therapy for Depression

While anecdotal reports of yoga therapy’s effectiveness for depression are abundant, what does the science say?

Research indicates that yoga therapy for depression does work. In a randomized controlled trial conducted by Uebelacker et al. (2017), individuals with persistent major depression who underwent adjunctive yoga therapy showed promising results compared to those receiving health education alone¹⁵. Specifically, 42% of participants in the yoga group achieved a notable 50% reduction in depressive symptoms at a 6-month follow-up, surpassing the 31% improvement rate observed in the control group. Moreover, yoga was also associated with significant enhancements in markers of physiological stress, including reductions in body cortisol (stress hormones) and IL-6 concentrations.

Yoga is More Effective Than Relaxation and Exercise

When evaluating the efficacy of yoga for depression, it is useful to compare it to other CAM therapies and therapeutic techniques. Researchers have seen that yoga as a holistic modality has an edge over specific techniques like relaxation and exercise when it comes to depressive symptom relief.

A meta-analysis by Cramer et al. (2013) reviewed twelve randomized controlled trials (RCTs) involving 619 participants and found evidence supporting the short-term effectiveness of yoga in reducing the severity of depression¹⁶. The study revealed that individuals practicing yoga had significantly lower depression scores than those receiving usual care. When compared to relaxation techniques, yoga offered distinct benefits for depression symptoms, though both were similarly effective in reducing anxiety.

Finally, compared to aerobic exercise, yoga showed a slight advantage in alleviating depression. This suggests that yoga’s effectiveness in treating depression may stem from its holistic approach, which integrates techniques targeting mind, body, spirit, lifestyle, and nervous system health.

Further supporting these findings, a recent comprehensive meta-analysis by Wu, Yan, and Yang (2023) examined data from 34 randomized controlled trials involving 2,341 patients confirmed that yoga therapy consistently leads to significant improvements in depressive symptoms across diverse patient populations¹⁷.

Relapse Prevention and Lasting Effects

One of the major challenges in treating depression is preventing relapse. The Wu analysis highlights the role of yoga therapy in reducing relapse rates. Regular yoga practice helps maintain mental and physical well-being, providing long-term benefits beyond immediate symptom relief.

The lasting benefits of mindfulness practices emphasize their therapeutic value in promoting stable mental health. These types of practices are often employed by yoga therapists to address depressive symptoms. Research by Walsh, Eisenlohr-Moul, and Baer (2016) demonstrated that even brief mindfulness training led to sustained reductions in salivary IL-6 levels for up to three months among young women with depressive symptoms¹⁸. This suggests that these practices may strengthen resilience and reduce the physiological signs of depression over time.

Together, these insights highlight how yoga therapy and mindfulness practices help treat depression and prevent future relapses, promoting lasting benefits.

Yoga Therapy’s High Adherence Rates

Adherence to treatment is crucial for its effectiveness, especially for depressive symptoms which are prone to relapse over time. Yoga therapy is established as highly well-received by a broad range of patients due to its holistic and accessible approach¹⁹. 

Indeed, many yoga therapy clients with MDD who sustain their home yoga therapy routines report previously trying exercise but struggling to maintain motivation. This is likely due to yoga’s holistic approach, which addresses the whole person and incorporates personalized practices aligned with individual beliefs. These “reconnection practices” nurture a sense of higher meaning, hope, and purpose.

Additionally, yoga therapy employs dynamic strategies to adapt to the client’s changing needs. Once depression symptoms lift, yoga therapy can then address any underlying anxiety symptoms. It also involves tailoring the client’s home practice sequence to be brief and strategically integrated into their daily routine, supporting continued adherence without sacrificing efficacy. This adaptability contributes to the low relapse rates observed in our client base.

Patients are more likely to stick with a practice they find enjoyable and beneficial, and yoga therapy is emerging as a popular CAM option for this reason.

Is Yoga Therapy for Depression Safe?

In discussions on using yoga as a therapeutic approach for depression, there is often criticism regarding the lack of rigorous safety studies integrated into research designs. However, clinical practice indicates that the personalized and adaptable nature of yoga therapy enhances its safety profile. 

When compared to the well-documented side effects and risks associated with antidepressant medications²⁰, which are commonly used as a first-line treatment for depression, evaluating how yoga therapy fares in terms of tolerability becomes crucial.

The Wu analysis found no adverse events in its broad review of yoga therapy for depression²¹. It also demonstrated that yoga therapy effectively reduces depressive symptoms during active treatment and offers sustained benefits due to its accessible and well-tolerated nature. These findings support yoga therapy as a safe and viable alternative or complement to conventional pharmacological treatments for depression.

Evaluating Risk in CAM Therapies for Depression

The relative safety of yoga therapy becomes especially apparent when comparing it to other therapies like ketamine, electroconvulsive therapy (ECT), and Transcranial Magnetic Stimulation (TMS). While ketamine and ECT are both potentially effective, they carry significant risks and potential side effects. Transcranial Magnetic Stimulation (TMS) is a less risky CAM option, but it requires repeated treatments and can cause mild symptoms like headache and scalp discomfort, along with the rare risk of seizures, mania, and cognitive disturbances. 

Private yoga therapy, though lesser-known and not usually covered by insurance, is readily accessible anywhere there is an internet connection via telehealth, and can be practiced with minimal to no side effects.

Cost Comparison of Yoga Therapy and Other CAM Therapies

When comparing CAM therapies based on cost, exercise is the most affordable and accessible option. However, many clients benefit from the additional support that yoga therapy provides. While the initial out-of-pocket investment for yoga therapy may be high, the benefits are lasting due to the educational nature and the resources and strategies clients gain for managing their mental health long-term.

For clients seeking a long-term, no-side-effect solution to their depression, who have tried or rejected other treatment options, yoga therapy offers a safe, effective, and enduring option that addresses the whole person.

Customized Approaches in Yoga Therapy for Depression

Yoga therapists approach depression progressively, tailoring practices to the individual’s current state. Initially, the focus is on depression-specific practices to stabilize and uplift the client’s mood. As the client’s energy levels and mood improve, therapists incorporate anxiety management practices to address any underlying or co-occurring anxiety issues. This staged approach ensures that the therapy remains effective and responsive to the client’s evolving needs.

Therapeutic Relationship and Support

Yoga therapists specialize in finding the right balance in yoga practice—identifying what feels like moderate intensity for the individual and determining an appropriate frequency together. The therapeutic relationship between the yoga therapist and the client is crucial. Reflecting on progress, providing encouragement, and reminding clients to practice outside of sessions can enhance adherence and outcomes.

Dosage

The right dosage of yoga practices is essential for effectively managing depression. Overdoing can lead to burnout, while too little may not yield significant benefits. A balanced, moderate approach is ideal.

A systematic review and meta-analysis by Brinsley et al. (2021) found that regular yoga practice significantly reduces depressive symptoms²². The study highlights that the frequency of yoga sessions per week is directly correlated with the reduction in depressive symptoms, suggesting that more frequent practice leads to greater efficacy. However, this must be balanced to avoid potential burnout from over-practicing.

Intensity Levels

Moderation in intensity is also crucial. While vigorous exercise can increase serum IL-6 levels, a marker of inflammation, moderate or low-intensity exercise tends to lower IL-6 levels, with moderate exercise being the most effective²³. This suggests that moderate-intensity yoga might be more beneficial for reducing depressive symptoms compared to high-intensity practices.

Tailoring the intensity and duration of yoga to individual needs is critical. Schuch et al. (2017) underscored the importance of personalizing exercise regimens for depression treatment²⁴. Implementing yoga therapy with sensitivity to each individual’s capabilities and responses ensures that the practice remains effective and sustainable.

Conclusion

Yoga therapy offers a holistic, accessible, and effective approach to managing depression. By addressing physical, mental, and emotional well-being, yoga therapy can significantly alleviate depressive symptoms, reduce relapse rates, and improve overall quality of life. Integrating yoga therapy into a comprehensive treatment plan can provide long-term benefits and support individuals in their journey toward mental health and wellness.
