From a Western perspective, aerobic exercise is touted as primary preventive and treatment option when it comes to blood pressure regulation; although too often, BP-lowering medications are also prescribed, alone or in combination with exercise recommendations. An Eastern alternative: tai chi, which should be adopted by more Western practitioners and institutions following the publication of new study findings in JAMA Network Open.
The randomized clinical trial by Dr. Zinye Li, and colleagues, featured 323 adults ages 18-65 diagnosed with prehypertension (systolic blood pressure 120-139 mm Hg and/or diastolic blood pressure of 80-89 mm Hg). The study, which took place at two tertiary hospitals in China, randomized patients to one of two groups in essentially equal numbers: a tai chi group and an aerobic exercise group.
Patients performed one intervention or the other, based on their randomization, four times weekly for 12 months. Each session lasted one hour. The primary outcome assessed: systolic blood pressure after one year; with secondary outcomes including systolic BP after six months; diastolic BP after six and 12 months; and ambulatory blood pressure at 12 months.
Key findings: As stated by the researchers, “At 12 months, the change in office SBP was significantly different between groups by −2.40 (95% CI, −4.39 to −0.41) mm Hg (P = .02), with a mean (SD) change of −7.01 (10.12) mm Hg in the Tai Chi group vs −4.61 (8.47) mm Hg in the aerobic exercise group. The analysis of office SBP at 6 months yielded similar results (−2.31 [95% CI, −3.94 to −0.67] mm Hg; P = .006). Additionally, 24-hour ambulatory SBP (−2.16 [95% CI, −3.84 to −0.47] mm Hg; P = .01) and nighttime ambulatory SBP (−4.08 [95% CI, −6.59 to −1.57] mm Hg; P = .002) were significantly reduced in the Tai Chi group compared with the aerobic exercise group.”

The end of cancer treatment does not necessarily signal a return to good health. Cancer survivors report poorer health and well-being than people who have not had cancer; many suffer chronic consequences of cancer and its treatments. Some may also develop new symptoms many years after treatment has ended.
