Deep dives
Low Quality of Scientific Evidence for Yoga
The lack of defined parameters for yoga studies leads to difficulties in interpreting the effects and comparing results. Different studies use varying components of yoga, such as postures, breathing exercises, and meditation, making it challenging to determine if yoga as a whole is effective. A review of more than 50 different yoga styles found no apparent winner in terms of positive results, suggesting that different styles may be interchangeable.
Mixed Results for Mood and Anxiety Disorders
While yoga appears to be helpful for anxiety, it does not seem to provide significant benefits for diagnosed anxiety disorders or mood disorders like depression. Studies comparing yoga to control interventions like social support or doing nothing have shown no significant effects in improving depressive symptoms or mental well-being.
Potential Benefits and Risks of Yoga
Yoga has shown potential benefits for conditions like irritable bowel syndrome and ulcerative colitis, improving quality of life and disease activity. However, studies have also noted risks and injuries associated with certain yoga poses, such as vertebral compression fractures and meniscus injuries. Beginners should be cautious, particularly with high-risk poses, hot yoga, and during pregnancy.
