Why does the element sodium help us in are daily lives?

Answer 1

* Salt is essential not only to life, but to good health. It's always been that way. Human blood contains 0.9% salt (sodium chloride) -- the same concentration as found in United States Pharmacopeia (USP) sodium chloride irrigant commonly used to cleanse wounds. Salt maintains the electrolyte balance inside- and outside of cells. Routine physical examinations measure blood sodium for clues to personal health.

Most of our salt comes from foods, some from water. Inadequate salt can be problematic. Doctors often recommend replacing water and salt lost in exercise and when working outside. Wilderness hikers know the importance of salt tablets to combat hyperthermia. Expectant mothers are advised to get enough salt.

Increased salt intakes have been used successfully to combat Chronic Fatigue Syndrome. The unique microclimate of salt mines is a popular way to treat asthma, particularly in Eastern Europe. Dramatic deficiencies (e.g. "salt starvation" in India) or "excessive" sodium intakes have been associated with other conditions and diseases, such as hypertension and stomach cancer.

Testing the salinity of perspiration is a good test for cystic fibrosis; scientists suspect that cystic fibrosis is caused by a deformed protein that prevents chloride outside cells from attracting needed moisture. (And, of course, we cannot forget that iodized salt is the choice of public health professionals to combat iodine deficiency, has been fortified to battle other diseases like lymphatic filarisis and is considered "the first antibiotic").
