Improves Cardiac Health
Regular soaking in the hot tub promotes better cardiac health. Immersing the body neck-deep into the hot tub produces a variety of benefits that significantly improve an individual’s overall cardiac health. Studies say that when someone sits in the hot tub up to their neck, they automatically give the heart a workout because of the warmth of the water.
Once the body recognizes that the water is heated, the body responds by increasing its core temperature, which also warms and excites the blood. When the blood becomes warm, it also begins to warm the organs and other deep muscle tissues. The heat of the water also dilates blood vessels, automatically lowering blood pressure and shifting the blood volume from the extremities to the chest cavity. This leads to the heart pumping more blood to the organs with each beat, making it more efficient.
The relatively hot water temperature also decreases any circulatory resistance. This, coupled with increased pump efficiency, leads to a more efficient cardiovascular system when immersed in the hot tub. Also, because the water allows the heart to work with less effort, the experience in the hot tub is akin to giving the ticker a brief rest.
