In the study, researchers in China randomly assigned 342 adults with prehypertension to one of two interventions. The average age of participants was 49. Roughly half the people participated in supervised aerobic exercise, including jogging, climbing stairs, brisk walking and cycling. The other half was trained to practice tai chi. Both groups got hourlong sessions four times a week.
So what is it about tai chi that helps lower blood pressure? The practice tends to eleme stress and promote relaxation, while also improving flexibility and balance.
