The Plasma content of blood (the fluid part, or water part, as opposed to the solids part) is reported to be about 55% in a ‘normal’ individual. Even if there was a definitive ‘normal’ measurement, it would be based on the average of the current population, which is a poor base for a statistic, as most people are likely chronically dehydrated
. I imagine if there was a even a mild lack of fluid available in the body, the blood would become thicker, or more viscous, slowing its ability to flow and making the heart work harder. Could this be related to High Blood Pressure, I hear you ask?
I often think about the use of Aspirin to ‘thin the blood’. This implies that keeping the blood thin is important? Hmmm…. maybe so it can move around more efficiently, so that O2 and nutrients can do their stuff. Isn’t this what water in the blood does? If your blood is thick it moves slower, denying efficient delivery to, and elimination from, cells.
I have a client who I felt was dehydrated when he first came to me. He had no idea this was the case. After talking to him about water (which he never drank) he told me that when he gave blood it took ages to get any blood out. The nurses told him he had thick blood so it didn’t flow well. After increasing his water intake, the problem of slow flow when he gave blood stopped. He gave the full measure, quick as can be for the first time in 30 years, and the only thing he did was increase his water intake.
Modern day marketing for medicine, pharmaceuticals and vitamin companies has led us all to focus on solids within blood (ie, iron, vitamins, medications, etc, etc) as the sole regulators of what happens in the body, and this certainly is true, but if the means of transporting those solids is hindered or lacking, and the main focus is on the ‘deemed to be lacking’ solid, then perhaps we are missing a pretty important point.
