A short daily respiratory exercise reduced systolic blood pressure in older adults, with effects comparable to medication and exercise, researchers report.

A brief, device-assisted breathing exercise performed for just five minutes a day has been shown to significantly reduce systolic blood pressure, according to a peer-reviewed study published in the Journal of the American Heart Association. Researchers reported an average drop of nine points, a level of improvement often associated with standard antihypertensive treatments or structured aerobic exercise programs.
The technique, known as high-resistance inspiratory muscle strength training, was tested in a randomized, double-blind, placebo-controlled clinical trial involving 36 participants between the ages of 50 and 79 who had elevated blood pressure. The study was conducted by a research team from the University of Colorado Boulder.
Participants were divided into two groups. One group completed a daily regimen of 30 forceful inhalations using a handheld device calibrated to provide high resistance, while the control group used a similar device set to minimal resistance. Each session took approximately five minutes to complete. Researchers monitored adherence and tracked blood pressure changes over a six-week intervention period, followed by an additional six weeks to evaluate whether the effects persisted.
At the conclusion of the initial phase, the group using the high-resistance method experienced an average reduction of nine points in systolic blood pressure. These improvements remained evident during the follow-up period, even after participants stopped the exercise.
The study also documented measurable changes in vascular health. Endothelial function, which reflects the ability of blood vessels to dilate, improved by 45% among participants using the high-resistance device. Researchers also observed increases in nitric oxide levels, a key factor in maintaining healthy blood vessels, along with reductions in inflammation and oxidative stress markers.
Lead researcher Daniel Craighead, Ph.D., said the findings highlight the efficiency of the method. He noted that the approach requires significantly less time than traditional exercise routines and may produce lasting benefits. Craighead also emphasized that the technique can be performed at home with minimal equipment, potentially making it accessible for individuals who face barriers to conventional treatment options.
Researchers cautioned that the findings should not be interpreted as a substitute for prescribed medical care. Participants and patients are advised to consult healthcare providers before making any changes to medication or lifestyle regimens.
The breathing technique itself is not new. It was originally developed to help patients with respiratory conditions such as chronic obstructive pulmonary disease strengthen their breathing muscles. The recent study modified earlier protocols by increasing resistance while reducing the time commitment from longer sessions to a short, daily routine.
Devices used for the exercise are commercially available and relatively low-cost, making the intervention a potential option for individuals seeking non-drug approaches to managing blood pressure.
The study contributes to ongoing research into alternative strategies for addressing hypertension, a condition affecting a large portion of the adult population and a major risk factor for cardiovascular disease. Researchers continue to explore how time-efficient, non-pharmaceutical methods may complement existing treatments and support long-term cardiovascular health.
