Relaxation techniques such as tai chi, yoga, meditation and breathing control may help reduce high blood pressure in the short term, according to new research from the Universities of Exeter and Bristol. The study reviewed data from 54 previous trials and found modest but consistent reductions in blood pressure among people practising these methods. The interventions were particularly effective when compared to those receiving standard care or placed on waiting lists, with the largest drops seen in systolic blood pressure – the upper number in a reading.

Despite these findings, researchers cautioned that the overall quality of evidence was mixed and that few studies assessed long-term outcomes. Most trials only tracked results for three months or less, suggesting that while initial benefits are promising, it remains uncertain whether these reductions are sustained over time. The study, published in BMJ Medicine, recommends more rigorous trials with extended follow-up periods to evaluate the lasting impact of relaxation therapies.
High blood pressure affects over 14 million people in the UK, especially among older adults, and is often symptomless. It is typically diagnosed when readings exceed 140/90 mm Hg in those under 80, or 150/90 mm Hg for people over 80. Commenting on the findings, Emily McGrath, senior cardiac nurse at the British Heart Foundation, noted that while relaxation methods may ease stress and temporarily lower cortisol levels, further research is needed to confirm their long-term efficacy in blood pressure control.

McGrath added that current health guidance already encourages activities such as yoga or Pilates as part of a broader lifestyle approach to managing blood pressure. She emphasised the importance of regular physical activity, maintaining a healthy weight, eating a balanced diet, reducing salt intake, limiting alcohol, and adhering to prescribed medication. As age, family history, ethnicity and weight are key risk factors for hypertension, early detection and lifestyle changes remain vital tools in tackling this widespread condition.
