The Effects of Sodium on The Human Body

Sodium (salt) has a huge effect on the human body. Know what it does and how it functions is vital to living a healthy life. This article explains the basics about sodium and the human body.

How does sodium effect your body?

Sodium is vital for your body to function correctly. It helps your body maintain the correct balance of fluids in your body, assists transmit nerve impulses, and influences the contraction and relaxation of muscles.

When you consume sodium, your kidneys regulate the amount of sodium that remains in your body, and the amount that is wasted. When you have an abundance of sodium, your kidneys excrete the excess sodium out of your body via your digestive system. When there is a minimal amount of sodium in your body, your kidneys conserve it.

If in some situation you can not remove the excess sodium, then it will begin to collect in your blood, and since sodium attracts water, your blood volume increases. The more blood volume you have, the harder your heart has to work to keep the blood moving which consequently increases the pressure in the arteries.

Some people are more sensitive to sodium then others are. Sensitivity to sodium causes people to retain sodium more easily, leading to excess fluid retention and higher blood pressure. This can be avoided by lowering your sodium intake and getting enough exercise.

How much sodium should I be getting every day?   

Generally, for a healthy adult, not exceeding 1,500 or 2,400 milligrams (mg) a day is recommended. Depending on your age and health condition (ex. High blood pressure, diabetes, or chronic kidney disease), you may be more sensitive to sodium. In this case, you should try to stay in the 1,400-500 mg range.
