Yoga is working on an even higher plane to drive down the stresses of the day, put them in perspective and help you cope better in the future when not-so-great things come your way. In addition to keeping your body young, yoga turns back the years on your brain, too. In one study published in the journal International Pschogeriatrics, older adults over age 55 with mild cognitive impairment spent 12 weeks either practicing Kundalini yoga or memory training.
Additional observational research on mindfulness and meditation both are large components of yoga sheds light on how classes may actually influence your brain structure, says Greenberg. Research on yoga alone is limited, but you can make some inferences by looking at meditation studies, he notes. Studies looking at how the brain changes before and after meditation found that brain structures involved in awareness, attention and self-related thinking changed in structure and increased in volume, he says. As Greenberg points out, those who meditate have larger right insula the portion of the brain that involves body awareness.
Your amygalda — the reptilian part of your brain that reacts to fear —may also decrease in reactivity in response to stress. There are plenty of overall health perks too: Research from shows yoga can decrease inflammation, boost your immune system , and improve symptoms of chronic health conditions such as type 2 diabetes, cardiovascular disease, and cancer.

More recent research also found that a steady yoga practice can do wonders for your mental health and mood, reducing depression. Prathikanti S, et al.

Try out different styles and teachers until you find one that most resonates with you. If you like a fiery practice, combine it with a gentle practice every now and then. Watch on your Television. She had no sensation on the right side of her body; her left arm and leg responded poorly to her commands. You also need to be aware that during pregnancy the body produces hormones relaxin which will make you more flexible especially in the hips and pelvis. People get so hung up on alignment, they cut off the vital chi of flow through the body.
But can an average person actually reap these benefits, or do you have to spend half your salary on unlimited access to a yoga studio to see a change? Practicing once a week is good. Science can back up some of these claims. For example, an older but compelling study found that a single yoga class could significantly reduce tension, anxiety , depression, anger, hostility, and fatigue among inpatients at a psychiatric hospital. Lavey R, et al. The effects of yoga on mood in psychiatric inpatients.
In another study, doing yoga just once a week for 6 weeks was enough to improve spine and hamstring flexibility. Amin DJ, et al. The effects of selected asanas in Iyengar yoga on flexibility: Pilot study. A year study with participants found that just 12 minutes of yoga per day is enough to see improvements, at least when it comes to preventing osteoporosis and strengthening bones.
Not just students but celebrated teachers too, Black said, injure themselves in droves because most have underlying physical weaknesses or problems that make serious injury all but inevitable. Or it can be used therapeutically. According to Black, a number of factors have converged to heighten the risk of practicing yoga.

The biggest is the demographic shift in those who study it. Indian practitioners of yoga typically squatted and sat cross-legged in daily life, and yoga poses, or asanas, were an outgrowth of these postures.
Now urbanites who sit in chairs all day walk into a studio a couple of times a week and strain to twist themselves into ever-more-difficult postures despite their lack of flexibility and other physical problems. Many come to yoga as a gentle alternative to vigorous sports or for rehabilitation for injuries. He spoke of well-known yoga teachers doing such basic poses as downward-facing dog, in which the body forms an inverted V, so strenuously that they tore Achilles tendons. Among devotees, from gurus to acolytes forever carrying their rolled-up mats, yoga is described as a nearly miraculous agent of renewal and healing.
They celebrate its abilities to calm, cure, energize and strengthen. And much of this appears to be true: yoga can lower your blood pressure, make chemicals that act as antidepressants, even improve your sex life. But the yoga community long remained silent about its potential to inflict blinding pain. Jagannath G. Pattabhi Jois and Bikram Choudhury.
The problems ranged from relatively mild injuries to permanent disabilities. In one case, a male college student, after more than a year of doing yoga, decided to intensify his practice. He would sit upright on his heels in a kneeling position known as vajrasana for hours a day, chanting for world peace.
Soon he was experiencing difficulty walking, running and climbing stairs. Doctors traced the problem to an unresponsive nerve, a peripheral branch of the sciatic, which runs from the lower spine through the buttocks and down the legs.
Sitting in vajrasana deprived the branch that runs below the knee of oxygen, deadening the nerve. Once the student gave up the pose, he improved rapidly.
More troubling reports followed. In a prominent Oxford neurophysiologist, W. Ritchie Russell, published an article in The British Medical Journal arguing that, while rare, some yoga postures threatened to cause strokes even in relatively young, healthy people. Russell found that brain injuries arose not only from direct trauma to the head but also from quick movements or excessive extensions of the neck, such as occur in whiplash — or certain yoga poses.
Normally, the neck can stretch backward 75 degrees, forward 40 degrees and sideways 45 degrees, and it can rotate on its axis about 50 degrees. Yoga practitioners typically move the vertebrae much farther. An intermediate student can easily turn his or her neck 90 degrees — nearly twice the normal rotation.
Hyperflexion of the neck was encouraged by experienced practitioners. Extreme motions of the head and neck, Russell warned, could wound the vertebral arteries, producing clots, swelling and constriction, and eventually wreak havoc in the brain. The basilar artery, which arises from the union of the two vertebral arteries and forms a wide conduit at the base of the brain, was of particular concern.
It feeds such structures as the pons which plays a role in respiration , the cerebellum which coordinates the muscles , the occipital lobe of the outer brain which turns eye impulses into images and the thalamus which relays sensory messages to the outer brain.
Reductions in blood flow to the basilar artery are known to produce a variety of strokes. The majority of patients suffering such a stroke do recover most functions. But in some cases headaches, imbalance, dizziness and difficulty in making fine movements persist for years. Russell also worried that when strokes hit yoga practitioners, doctors might fail to trace their cause. A healthy woman of 28 suffered a stroke while doing a yoga position known as the wheel or upward bow, in which the practitioner lies on her back, then lifts her body into a semicircular arc, balancing on hands and feet.
An intermediate stage often involves raising the trunk and resting the crown of the head on the floor. The woman was rushed to the hospital. She had no sensation on the right side of her body; her left arm and leg responded poorly to her commands. Her eyes kept glancing involuntarily to the left.
Nagler reported that the woman also had a tendency to fall to the left.
