Quick answer: Tai Chi lowers blood pressure, and in the best recent trial it did so better than aerobic exercise. In a 2024 randomized trial of 342 adults with prehypertension published in JAMA Network Open, 12 months of Tai Chi reduced systolic blood pressure by about 7 mmHg, compared with about 4 mmHg for jogging, cycling and brisk walking, with an even larger advantage in night-time readings. Here is what that study and others found, why slow movement affects the cardiovascular system, and how to start if you are already on medication.

What the studies found
The 2024 Tai Chi versus aerobic exercise trial
JAMA Network Open, February 2024
342 adults aged 18 to 65 with prehypertension were randomized to four supervised 60-minute sessions a week of either Tai Chi or aerobic exercise for 12 months. Tai Chi produced a significantly greater fall in office systolic pressure (2.4 mmHg more than aerobics), a greater fall in 24-hour ambulatory pressure and a 4 mmHg greater fall in night-time pressure, the reading most closely linked to cardiovascular risk. Harvard Health’s summary puts the absolute drops at roughly 7 points for Tai Chi versus 4 for aerobics.
Why the night-time number matters
Harvard Health Publishing, 2024
Blood pressure that fails to dip at night is a stronger predictor of heart attack and stroke than daytime readings. The researchers suggest Tai Chi’s edge comes from triggering the relaxation response, lowering sympathetic nervous system tone in a way that persists into sleep. Aerobic exercise trains the heart; Tai Chi appears to also retrain the nervous system that controls the blood vessels.
The broader picture: nervous system balance
See our full research summary
Across trials, Qigong and Tai Chi consistently show favourable changes in both blood pressure and resting heart rate, which points to a shift from sympathetic (stress) toward parasympathetic (rest-and-repair) dominance. The same mechanism explains the sleep and anxiety benefits covered elsewhere in this series.
Why it works: research and tradition side by side
| What the research measures | What Qigong tradition calls it |
|---|---|
| Slow, deep breathing raises heart-rate variability and lowers sympathetic tone; blood vessels relax and pressure falls | Sinking the Qi; long, slow, fine, deep breath |
| Sustained relaxation during movement reduces circulating stress hormones that constrict arteries | Song (release) throughout the whole body |
| Gentle continuous leg work improves endothelial function and venous return without pressure spikes | Rooting; weight shifting from leg to leg |
| Regular practice improves sleep, which independently lowers blood pressure | Yin practice in the evening |
How to put it into practice
- Frequency beats intensity. The winning trial used four sessions a week. Daily 15 to 20 minutes is the practical equivalent and is what Qigong 101 is built around.
- Breathe first. Slow breathing alone measurably lowers blood pressure within minutes. Learn it properly in Qigong 101 and read the physiology in Secrets of Breathing.
- Use the Tai Chi Ruler. The Tai Chi Ruler is the gentlest way into Tai Chi-style weight shifting with the breath, and it is easy on the knees.
- Stand, but start short. Zhang Zhuang is excellent for circulation. Begin with two to five minutes; if you are on blood pressure medication, rise slowly afterwards.
- Keep taking your medication and keep measuring. Take your readings at the same time daily and share the log with your doctor. Many students’ doctors reduce doses over time based on those numbers, but that is the doctor’s call, never yours alone.

Frequently asked questions
Does Tai Chi lower blood pressure?
Yes. A 2024 randomized trial of 342 adults with prehypertension found 12 months of Tai Chi lowered systolic blood pressure by about 7 mmHg, more than aerobic exercise, with a larger advantage in night-time readings. Earlier meta-analyses also report consistent reductions.
Is Tai Chi better than walking for blood pressure?
In the 2024 JAMA Network Open trial, Tai Chi outperformed a mix of aerobic exercises including brisk walking, jogging, cycling and stair climbing for systolic blood pressure. Aerobic exercise remains important for overall fitness; the two are complementary.
How often do I need to practice Tai Chi to lower blood pressure?
The 2024 trial used four one-hour sessions a week. Shorter daily practice of 15 to 20 minutes is a realistic home equivalent and matches how most Qigong programs are taught.
Can I do Qigong if I take blood pressure medication?
Yes, in almost all cases. Continue your medication, rise slowly after standing practice, and record your readings for your doctor. Never change a dose without medical advice.
Is Qigong safe after a heart attack or with heart disease?
Tai Chi and Qigong are widely used in cardiac rehabilitation because they are low intensity and low risk. Get clearance from your cardiologist first, start seated if needed, and avoid breath holding.
