People are searching for the greatest hydration options as a result of the excessive heat that has affected the majority of the world. Skim milk provides the highest hydrating impact, according to a study from St. Andrews University in Scotland, reported CNN.

Researchers discovered that drinks with minimal sugar, fat, or protein perform an even better job of keeping us hydrated for a longer period of time than water, both still and carbonated, do at instantly hydrating the body.

According to research author and professor at St. Andrews Medical School Ronald Maughan, the cause has to do with how our bodies react to alcoholic beverages. The amount of a particular drink is one factor: The sooner you drink, the quicker it leaves your stomach and enters your bloodstream, where it can hydrate you and dilute bodily fluids.

The nutritional makeup of a drink is another aspect that affects how well it hydrates us. Because it contains the sugar lactose, protein, and fat, which all work to slow the emptying of liquids from the stomach and keep you hydrated for longer, milk has been discovered to be even more hydrating than plain water.

Additionally, salt, which functions as a sponge to hold onto water in the body and reduce urine production, is found in milk.

The same can be stated for diarrhea treatments that involve oral rehydration solutions. They have modest levels of sodium, potassium, and sugar, which can all contribute to the body’s tendency to retain water.
