The active ingredients of tai chiWhen Peter Wayne, medical editor of Introduction to Tai Chi from Harvard Medical School, began conducting scientific studies on the health benefits of tai chi, he began noticing that tai chi works in a variety of ways, not just one. Whereas most drugs have a single active ingredient, he observed that tai chi was more like a multidrug combination that uses different components to produce a variety of effects. 
Wayne formulated the idea of the "eight active ingredients" of tai chi, which he and his colleagues now use as a conceptual framework to help evaluate the clinical benefits of tai chi, explore the underlying mechanisms that produce these effects, and shape the way tai chi is taught to participants in clinical trials (and to teachers). While different styles of tai chi emphasize different ingredients, these therapeutic factors are interwoven and synergistic. Here's a summary of one of the active ingredients of tai chi.

Mind-body exercises, such as tai chi and yoga, have been gaining popularity over the past few decades. This is not surprising, given the increasing number of studies on the positive effects of these gentler forms of exercise—everything from lowering blood pressure and managing depression to building strength and improving balance. There is even evidence that tai chi may help you live a longer, more vital life.

Structural integration. Tai chi looks at the body as an interconnected system, not as a collection of individual parts. As a result, when practicing tai chi, you won't do one exercise for your biceps and another for your glutes. Instead, tai chi integrates the upper body with the lower body, the right side with the left side, and the extremities with the core. 
Alignment and posture are part of this structural integration, and tai chi trains you to find alignments that are safe and unstrained, allowing you to perform graceful movements. You move more efficiently—not just during your tai chi practice, but throughout your day. The result is less stress and load on your joints and better balance. 
Improved posture provides tai chi benefits that extend well beyond your class. When you walk or sit with your shoulders rounded and your torso hunched over, it is hard to take deep breaths. But when you straighten your back, roll your shoulders back and down, and open your chest, you breathe more deeply and efficiently. 
Not only does this integration improve your ability to move without pain, but it also affects your mental health. In two different studies, people who sat or walked more upright during the experiments had a more positive outlook afterward than those who slouched while sitting or walking.

A sharper mind: tai chi can improve cognitive functionThere are lots of jokes about forgetting where you put your keys, but as you get older, changes in your mental function are no laughing matter. Changes in your brain that start around age 50 can affect your memory, as well as other cognitive functions such as your ability to juggle multiple tasks, process information rapidly, and focus on details. By age 70, one in six people has mild cognitive impairment (which can progress to Alzheimer's disease).
Up until about two decades ago, it was believed that your brain only produced new cells early in life. But research has shown that the brain has the ability to change throughout your entire life span, growing new cells, making new connections, and even increasing in size. These changes can improve cognitive function—and various forms of exercise, including tai chi, can help.
In a meta-analysis of 20 studies on tai chi and cognition, tai chi appears to improve executive function—the ability to multitask, manage time, and make decisions—in people without any cognitive decline. In those with mild cognitive impairment, tai chi slowed the progression to dementia more than other types of exercise and improved their cognitive function in a comparable fashion to other types of exercise or cognitive training.
In one study, researchers had nearly 400 Chinese men and women with some cognitive impairment perform either tai chi or a stretching and toning program three times a week. After a year, the tai chi group showed greater improvements, and only 2% of that group progressed to dementia, while 11% from the traditional exercise group did.
In another study, tai chi outperformed walking. Following 40 weeks of either tai chi, walking, social interaction, or no intervention, researchers compared MRI images and discovered that brain volume increased the most in the tai chi group. In addition, that group also performed better on cognitive tests.
