How Much Salt Do You Lose Sweating?

A person loses about half a teaspoon of salt per pound of body weight when sweating, according to the Mayo Clinic Web site.

The American Heart Association says that while most people get enough sodium from food and fluids each day, too much sodium can raise blood pressure and lead to stroke or heart disease. Studies have found that even mild hypertension — a high blood pressure reading of less than 140/90 mmHg — doubles the risk for stroke among women with no risk factors for cardiovascular disease, such as diabetes, obesity or smoking. High blood pressure is also linked to increased chance of death from heart attack or stroke in adults between 55 years old and 74 years old. Women over 50 who are overweight have twice the risk of dying from heart-related problems compared with those whose weight stays within healthy ranges during middle age.
