Anyone who has used a spa before is familiar with the relaxing effect of the jets themselves, and their obvious benefits. Focused streams of water - with warmed air mixed within the flow - can provide a therapeutic massage that you can control; depending on how gentle or intense you want it to feel.
Hot tubs are equipped with nozzles of various sizes, pressures, configurations, and quantities - all designed to target particular portions of your body. Smaller groups of jets will hit pinpoint muscles around your neck. Many jets will focus on certain portions of your back. Larger flow jets will actually sweep up and down your entire back, just to the sides of your spine. Tiny jets will spin around your wrists. Other jets will aim for your calves, feet, or arms. Like a trained masseuse, the spa's jets can soothe sore muscles any time you need.
