Salt supports nerve signalling, muscle contraction, and fluid balance, but too much of it can be harmful to health, so setting a daily limit is important.

Recommended sodium intake

The World Health Organization recommends taking 2,000 mg of sodium (less than 5 grams of salt) every day. For optimum health, the American Heart Association recommends 1,500–2,300 mg.

Preventing heart problems

Adhering to sodium intake recommendations lowers the risk of strokes, cardiovascular disorders, and hypertension—all of which are associated with excessive salt intake.

Immediate effects of excessive salt

Consuming too much salt causes bloating, increased thirst, fluid retention, and a brief increase in blood pressure, all of which have an impact on fluid balance and general health.

Dehydration and increased thirst

When the body's fluid balance is upset by too much salt, the body tries to regain homeostasis, which results in dehydration and extreme thirst.

Swelling and water retention

The kidneys' inability to regulate sodium levels results in swelling, puffiness, and fluid retention, especially in the limbs and other body parts.
