Twenty-three healthy adults were asked to run on a treadmill for a total of 30 minutes on two separate occasions, after which they were monitored for two hours.
On each occasion at one, 30, 60 and 90 minutes after exercise they were asked to rinse their mouths with a liquid either antibacterial mouthwash or a placebo of mint-flavoured water. Neither the researchers nor the participants knew which liquid they were rinsing with.
Their blood pressure was measured and saliva and blood samples were taken before exercise and at 120 minutes after exercise.
The study found that when participants rinsed with the placebo, the average reduction in systolic blood pressure was -5.2 mmHg at one hour after exercise. However when participants rinsed with the antibacterial mouthwash, the average systolic blood pressure was -2.0 mmHg at the same time point.
