Sodium’s role in the human body is mainly to participate in the body’s metabolism; sodium’s harm to the human body is mainly to cause high blood pressure, harm to the central nervous system, etc., as follows.
1. The role of sodium in the human body: ① is the human body pancreatic fluid, bile, sweat and tears of the constituents; ② to maintain the body’s acid and alkali balance; ③ to participate in water metabolism, to ensure the balance of water in the body, regulating the body’s water and osmotic pressure; ④ to participate in muscle movement, cardiovascular function, energy metabolism, glucose metabolism, the use of oxygen, etc.; ⑤ can enhance neuromuscular excitability.
2. Sodium harm to the human body: ① cause hypertension: if the diet is salty, it will lead to an increase in the total amount of sodium in the body, thus increasing blood volume will lead to hypertension; ② harm to the central nervous system: when the concentration of sodium ions increases, sodium will be concentrated, resulting in dehydration symptoms in the central nervous system, there may be fatigue, lethargy, indifference, delirium, lack of clarity, coma, or even death, and other symptoms appear.
