Tai Chi has accumulating evidence to support its role in achieving overall systemic balance. This includes a positive impact on cell regeneration and healing, especially in the context of heathy aging.
A recent research study (May 2025) from Stanford University, USA1, conducted a comprehensive overview of more than 200 Tai Chi studies that explored the impact of this practice on cellular health and aging. Of these, 69 were deemed to meet the rigorous standards required for validity.
In this analysis, three areas of physiology were identified to play key roles in the beneficial healing practice of Tai Chi: fascia, circulation, and the stress response.
Let’s begin with our fascia.
Fascia is a mechanical system of connective tissue that surrounds and unifies the bones, muscles, organs, blood vessels and nerves. Fascia contains cells called fibroblasts. The role of fibroblasts is to deposit new collagen when tissue repair is needed and to release immune cells when inflammation occurs.
How does Tai Chi activate the fascia?
Fascia both senses and responds to specific types of mechanical stimuli. This is called fascial mechanotransduction; meaning when mechanical forces are applied to the fascia, they are sensed and transmitted throughout its tissues. And the slow, multidirectional and aligned movements of Tai Chi are exactly the stimuli that the fascia respond to.
As Tai Chi postures ask us to work on our external alignment, our fascia responds by realigning itself internally over the bones, muscles and organs. This means that the forces traveling across the underlying tissues are consequently spread out more evenly so that no single area is excessively loaded relative to another. This creates a ‘balancing effect” throughout the entire fascial tissues of the body. And when this happens, fibroblasts become stimulated and begin to release collagen for any needed cellular repair.
This healing process described helps to prevent tissue thickening, multiple adhesions and scarring from developing. With respect to the abdominal area, fascial opening allows for more space to be available for the organs to receive the beneficial nutrients they require for renewal and repair. This becomes especially important when internal damage related to injury, illness or disease is present.
The next impact of Tai Chi on our fascia has to do with our immune cells. Because Tai Chi alters the tension within the fascia, its fibroblasts also respond by delivering an increased number of immune cells into our system. There is mounting evidence that Tai Chi practitioners (over 1 year) demonstrate an improved capacity to balance their overall immune response. This means that the varied cells of their immune system work together in a more uniform manner. We have all experienced how uncomfortable and damaging excessive inflammation can be following an illness or injury. When we practice Tai Chi, we are keeping the more detrimental pro-inflammatory response in check, and this encourages faster healing.
Further to these wonderful benefits, fascial tissues also have the ability to sense the direction of our movements (via proprioceptors). When we practice Tai Chi, we are, in many ways, listening to our fascia speak to us, helping us to realign our movements and correct our postures so that the load applied is more evenly distributed. As a result, we are able to make any appropriate adjustments needed to maintain our alignment. This two-way communication between the fascia and our Tai Chi postures also creates a secondary stretch and opening internally, inviting needed nutrients to be delivered into our bloodstream.
Now let’s briefly review the impact of Tai Chi on our circulation. We all know that our practice improves the blood flow. We often feel warmth and perhaps pleasant tingling during or immediately following our practice. But what happens within our blood during Tai Chi?
Some exciting recent research has shown that long-time Tai Chi practitioners have a significantly increased number of a certain stem cell called CD34plus (compared to non-Tai Chi groups)2. Stem cells are unspecific cells that are capable of self-renewal and also have the ability to change into whatever specialized cells our bodies need. Examples are bone marrow (where most of our stem cells are), blood, heart, nerve, brain, gut, and muscle cells. These cells are stored in our bodies, ready to replace old, damaged ones and to help regenerate new ones. It is even postulated that Tai Chi may increase the length of our telomeres as a result of this enhanced stem cell activity. Telomeres are what protect the ends of our chromosomes (that hold our DNA) and help slow the overall aging process.
Finally, let’s touch on the relaxation and mindfulness aspects of our Tai Chi practice. We have previously discussed how our practice helps to regulate our stress response by actively engaging our vagus nerve3.
But what does the stress response have to do with cellular healing?
There is a Pathway, called HPA, which begins at the base of the brain (Hypothalamus) tracking to the (P) pineal gland, then to the (A) adrenals of the kidneys. When we experience stress, the brain releases hormones that eventually become cortisol, our primary stress hormone. And consistently high levels of cortisol in our blood can lead to anxiety, depression, not to mention damaging systemic inflammation that can interfere with the body’s ability to heal.
This is where Tai Chi enters the picture. By regularly engaging the vagus nerve during the practice of Tai Chi, this HPA pathway is ‘short circuited’, causing an important reduction of cortisol release in response to stress. The critical influence of Tai Chi on the HPA axis mechanism described translates into an improved a sense of calm, relaxation and well-being. And due to the lowering of cortisol and inflammation, healing is accelerated.
As always, we are grateful to Master Moy for the incredible gift of Tai Chi he has given us. It is one that we are increasingly appreciating for its immense value in supporting and advancing our health and ability to heal, both young and old.
