Acid-alkaline balance - is the pH of human blood and other fluids in our body for medical reasons should range from 7.35 to 7.45. The average pH of the blood of a healthy person is 7.42. Therefore, drinking water must comply with these pH values.

When a person drinks sea water or salt water, it changes the acid-base balance in the human body - this has negative health effects.

Drinking of seawater will cause a kidney failure.

Well,

No firm conclusions can be drawn concerning the possible association between sodium in drinking-water and the occurrence of hypertension. Therefore, no health based guideline value is proposed. However, concentrations in excess of 200 mg/l may give rise to unacceptable taste. but the problem in its compound;

I quote from (WHO,2011), MENTIONED, Studies of the toxicity of sodium cyanurate are appropriate for assessing the safety of sodium dichloroisocyanurate, because any residues of intact sodium dichloroisocyanurate in drinking-water would be rapidly converted to cyanuric acid on contact with saliva. Both sodium dichloroisocyanurate and sodium cyanurate have low acute oral toxicity. Sodium cyanurate does not induce any genotoxic, carcinogenic or teratogenic effects. The NOEL from which the guideline value was derived was based on multiple lesions of the urinary tract (calculi and hyperplasia, bleeding and inflammation of the bladder epithelium, dilated and inflamed ureters and renal tubular nephrosis) and cardiac lesions (acute myocarditis, necrosis and vascular mineralization) in male rats exposed at the next higher dose.

Drinking of seawater will dehydrate us.

Violation of the acid-base balance in the use of salt water is dangerous concentration increases

salt in the blood and primarily sodium ions.

Hyponatremia (the concentration of sodium ions in the serum

Drinking seawater would produce basically the same effects as salt/osmotic stress in plants: dehydration at cellular level. Then, likely more concentrated urine and finally, kidney failure. If you are interested in this phenomenon in animal kingdom, take a look on marine reptiles and birds - they have structural and anatomical adaptations to cope with saline water. I included few of these aspects in my book - STRUCTURI SECRETOARE DE SĂRURI LA HALOFITE. O ABORDARE INTEGRATIVĂ/ SALT SECRETING STRUCTURES OF HALOPHYTES. An integrative approach, Marius Grigore and Constantin Toma, Romanian Academic Press, 2010.

It is inadvisable due to high salinity, it may damage body organs.

Drinking of seawater can increase the blood pressure and dysfunction the kidneys.

Author Alfred Pischinger was the first scientist to develop a theory for complementary (holistic) medicine based on the regulation of the extracellular matrix (ground regulation). The extracellular matrix is a network of proteins that surrounds and supports all cells and tissues in the body. In other words, it’s a connective tissue that bridges the gap, giving all of our cells a pathway to communicate with one another. Alfred Pischinger’s discoveries, involving the extracellular matrix, transformed the way doctors and scientists thought about health and disease. It solidified the idea that everything in the body is connected. Undeniably, when one system is down, other systems are easily impacted. This reader is Chapter 1: Structure and Function of the ECM. "Cells have a reciprocal relationship with their environment. Seawater is the primary regulatory system of the single cell. In multicellular organisms, the ion composition of the structured extracellular space corresponds to seawater."
