In April 2020 researchers from China published their review of the medical scientific literature to assess the influence of tai chi on blood pressure and related risk factors in individuals with hypertension. A total of 13 studies met the search criteria and were included in the review. Results showed that there was a significant difference between those undertaking tai chi and control groups with regard to change in both systolic and diastolic blood pressure levels. A further analysis revealed that 24-movement or yang-style tai chi significantly reduced both systolic and diastolic blood pressure levels over a period of 12 weeks or more in all studies whereas other styles of tai chi did not significantly reduce blood pressure levels. Further research is required.
