3 evidence-based benefits of tai chi

The Bottom Line

  • Tai chi is a mind-body exercise practiced by more than 300 million people worldwide.
  • Research shows that tai chi may improve cognitive function, support diabetes management, and reduce symptoms of anxiety and depression.
  • Speak with your healthcare team about if and how to incorporate tai chi into your exercise routine. 

Tai chi is a mind-body practice characterized by slow, controlled movements and deep, natural breathing (1). Originating in China, it’s now practiced by more than 300 million people across the globe (1;2). Given tai chi’s popularity, it should come as no surprise that researchers have taken interest in its potential impacts on everything from our cognitive health to diabetes management (3-6).

1. Improves cognitive function

Many of us seek activities that help us stay sharp as we age. Research shows that tai chi may help enhance working memory in adults over 50 with or without mild cognitive impairment (3). Working memory refers to the ability to temporarily hold onto and use information to complete a task, such as cooking a new recipe.  


2. Supports diabetes management

Uncontrolled type 2 diabetes can increase the risk of experiencing many health issues, including heart attacks, strokes, vision loss, and nerve damage that leads to amputations (7). To lower these risks, diabetes management is key. Research shows that tai chi may reduce fasting blood sugar and body mass index in people living with type 2 diabetes. Additionally, certain aspects of quality of life may also improve (4;5).   


3. Enhances mental health

Internationally, depression and anxiety continue to be two of the most common mental health disorders (8;9). Research shows that traditional Chinese exercises like tai chi may decrease symptoms of depression and anxiety in older adults. Optimal effects on symptoms are dependent on the characteristics of the tai chi program (6).    


Tai chi appears to be a safe, low-impact exercise that older adults can add to their optimal aging toolkits. Practiced at home with the help of a YouTube video or at the park with peers and the guidance of a teacher, tai chi offers flexibility and community. Speak with your healthcare team about whether tai chi is a good fit for you.
