Bodily
Fluid Level
Within
a half-hour, the blood diluted by 20%. This indicates the bodily fluid
(plasma) level had increased by 20%. This additional fluid came from
body tissue.
Stress
The
stress hormones are adrenaline and non-adrenaline. A high stress level
produces more of these hormones, but the increase of plasma level brought about
by soaking in warm water causes the hormones to become diluted and the rapid
dilution of the stress hormones can lead to feeling less stressful.
Heart
Function
There
are bands of muscle surrounding the veins and arteries in your body. The
effect of weightlessness is to relax these surrounding muscles, which allows the
veins to increase in diameter. The end result is that the blood can flow
through your body more easily. The experiments showed that increasing
temperature causes direct increase in blood flow. There is a 35% increase
at about 91 degrees, a 100% increase at 98.6 degrees. During this
increasing flow, the pulse rate does not change. The heart is pumping more
blood without having to work harder.
What
Are the Advantages of Soaking ?
The
loss of salts and minerals (electrolytes) may help kidney disorders, gout,
hypertension, and cirrhosis.
The
increase in bodily fluid (plasma) level helps remove inflammation from joints
and helps heal muscle injuries and fractures. It also helps reduce stress
by lowering hormone levels.
Increasing
blood flow without increasing heart rate is less work for the heart, which may
also help congestive heart failure. Muscle and tissue repair faster with
increased blood flow. The bodys detoxifying system works faster with
increased blood flow.
