Participants will either attend IY sessions or partake in social activities as a control group to compare effects on their mental health condition.See study design
What are the potential side effects?
While not explicitly stated for this trial, typical side effects from practicing yoga might include muscle soreness or strain. The socialization control activity is unlikely to cause physical side effects but could potentially affect emotional state.

Other Research
Common treatments for Prolonged Grief Disorder (PGD) often involve physical and mental exercises that aim to improve mental health and potentially alter neurobiological pathways. Techniques such as Iyengar Yoga, mindfulness meditation, and cognitive-behavioral therapy (CBT) work by promoting relaxation, reducing stress, and enhancing emotional regulation. These practices help in modulating the body's stress response, improving mood, and fostering a sense of well-being. For PGD patients, these treatments are crucial as they address both the psychological and physiological aspects of grief, potentially leading to better mental health outcomes and improved quality of life.
