In a hot tub, as the water comes through the pipes, it has a degree of force. This force is caused by the action of the pump, which puts energy into the circulating system and forces the water through the pipes. When the pump is off, there still may be water in the pipes, but there is no force. The degree of force in the system when the pump is on can be gauged in several ways, such as by putting your hand in front of a “jet.” Another way would be to have a device to measure the amount of force that the water exerts against the walls of the pipes as it circulates. Such a device might yield a numerical measurement of the force, or pressure, of the water within the pipes.
“Exercise, particularly cardio and aerobic exercise, has been known to be a potent dropper of blood pressure for a long time, and we know that fruits and vegetables rich in potassium and naturally occurring nitrates can actually lower blood pressure as effectively as many of the medications,” he said. “So that, to me, is no surprise. It’s nice that they put it all together in this study.”
It's time to heed your partner's complaints and get that snoring checked out. Loud, incessant snores are a symptom of obstructive sleep apnea (OSA), a disorder characterized by brief yet potentially life-threatening interruptions in breathing during sleep. And many sleep apnea sufferers also have high levels of aldosterone, a hormone that can boost blood pressure, according to University of Alabama researchers. In fact, it's estimated that sleep apnea affects half of people with high blood pressure.
