At some point between the 1st and 5th century CE, the Hindu sage Patanjali began to codify the ancient meditative traditions practiced throughout India.
Explore how yoga benefits the body and brain through physical postures, breathing, and meditation, backed by scientific insights.
Key Takeaways
- Yoga combines physical, breathing, and mental practices for holistic health benefits.
- It reliably improves flexibility, strength, and mobility, especially in people with musculoskeletal conditions.
- Breathing exercises in yoga enhance lung function and cardiovascular health.
- Yoga helps reduce stress and promote relaxation, though mental health benefits need more research.
- More rigorous, diverse studies are needed to fully understand yoga's health impacts.
Summary
- Yoga originated from ancient Indian meditative traditions codified by Patanjali in the Yoga Sutras.
- Modern yoga combines physical postures, breathing exercises, and spiritual contemplation.
- Yoga improves strength and flexibility by stretching muscles, ligaments, and tendons and stimulating stem cells.
- Yoga is effective in reducing pain and improving mobility in musculoskeletal disorders like chronic back pain and arthritis.
- Breathing exercises in yoga help relax airway muscles, improving lung function and oxygen diffusion.
- Yoga can lower blood pressure and reduce cardiovascular disease risk factors.
- Psychological benefits of yoga include stress reduction and relaxation, though evidence on depression and anxiety is less conclusive.
- Research on yoga's health benefits is limited by small, non-diverse samples and subjective self-reporting.
- Future studies need larger, more diverse populations to assess yoga's impact on heart attacks, cancer, and cognitive function.
- Yoga remains a valuable practice for physical exercise, mental reflection, and relaxation.

Speaker A
He recorded techniques nearly as old as Indian civilization itself in 196 manuals called the Yoga Sutras.
Speaker A
These texts defined yoga as the yoking or restraining of the mind from focusing on external objects in efforts to reach a state of pure consciousness.
Speaker A
Over time, yoga came to incorporate physical elements from gymnastics and wrestling. Today, there are a multitude of approaches to modern yoga.
Speaker A
Though most still maintain the three core elements of Patanjali's practice: physical postures, breathing exercises, and spiritual contemplation.
Speaker A
This blend of physical and mental exercise is widely believed to have a unique set of health advantages, such as improving strength and flexibility, boosting heart and lung function, and enhancing psychological well-being.
Speaker A
But what have contemporary studies shown regarding the benefits of this ancient tradition?
Speaker A
Despite attempts by many researchers, it's tough to make specific claims about yoga's advantages. Its unique combination of activities makes it difficult to determine which component is producing a specific health benefit.
Speaker A
Additionally, yoga studies are often made up of small sample sizes that lack diversity, and the heavy reliance on self-reporting makes results subjective.
Speaker A
However, there are some health benefits that have more robust scientific support than others. Let's start with flexibility and strength.
Speaker A
Twisting your body into yoga's physical postures stretches multiple muscle groups. In the short term, stretching can change the water content of these muscles, ligaments, and tendons to make them more elastic.
Speaker A
Over time, regular stretching stimulates stem cells, which then differentiate into new muscle tissue and other cells that generate elastic collagen. Frequent stretching also reduces the body's natural reflex to constrict muscles, improving your pain tolerance for feats of flexibility.
Speaker A
Researchers haven't found that any one form of yoga improves flexibility more than another.
Speaker A
So the impact of specific postures is unclear.
Speaker A
But like other low-impact exercises, yoga reliably improves fitness and flexibility in healthy populations.
Speaker A
The practice has also been shown to be a potentially powerful therapeutic tool.
Speaker A
In studies involving patients with a variety of musculoskeletal disorders, yoga was more helpful at reducing pain and improving mobility than other forms of low-impact exercise. Adding yoga to an existing exercise routine can improve strength and flexibility for hard to treat conditions like chronic lower back pain, rheumatoid arthritis, and osteoporosis.
Speaker A
Yoga's mix of physical exercise and regimented breathing has proven similarly therapeutic for lung health.
Speaker A
Lung diseases like chronic bronchitis, emphysema, and asthma shrink the passageways that carry oxygen, while weakening the membrane that brings oxygen into the blood.
Speaker A
But breathing exercises like those found in yoga relax the muscles constricting those passageways and improve oxygen diffusion.
Speaker A
Increasing the blood's oxygen content is especially helpful for those with weak heart muscles who have difficulty pumping enough oxygen throughout the body.
Speaker A
And for those with healthy hearts, this practice can lower blood pressure and reduce risk factors for cardiovascular disease.
Speaker A
Yoga's most widely celebrated benefit may be the most difficult to prove.
Speaker A
Its psychological effects.
Speaker A
Despite the long-standing association between yoga and psychological well-being, there's little conclusive evidence on how the practice affects mental health.
Speaker A
One of the biggest claims is that yoga improves symptoms of depression and anxiety disorders.
Speaker A
Since diagnosis of these conditions varies widely, as do their origin and severity, it's difficult to quantify yoga's impact.
Speaker A
However, there is evidence to suggest that yoga can help reduce symptoms of stress, as well as meditation or relaxation.
Speaker A
Research on the effects of yoga is still evolving.
Speaker A
In the future, we'll need larger studies incorporating diverse participants, which can measure yoga's impact on heart attacks, cancer rates, cognitive function, and more.
Speaker A
But for now, yoga can continue its ancient tradition as a way to exercise, reflect, and relax.
