Hydration – Sea salt helps the body absorb water for optimal hydration and helps the body stay hydrated for longer periods of time. Reduced Fluid Retention – Sea salt is loaded with minerals such as potassium and sodium that help release retained water.
Does adding sugar to water make it boil faster?
Sugar did not increase the boiling point temperature. Sugar molecules are 6 times larger than salt molecules, therefore there are more salt molecules per sheet than salt molecules, since the sugar molecules are 6 times larger than salt molecules. This results in more salt-water bonds in the sugar than in the water.
