You can always have a glass of water, but H2O is not the most hydrating drink, according to a study from St. Andrews University in Scotland that compared the hydration responses of several different drinks.
Water has been the favorite drink when it comes to hydration. The World Health Organization (WHO) recommends drinking between 1.5 and 2 liters of water a day because it is essential at any stage of life to regulate body temperature, keep the skin hydrated and elastic, and lubricate the joints. and organs and also to maintain good hydration.
Hydration is the replenishment of body fluids that are lost through sweat, exhalation, elimination of waste such as urine, and defecation.
Researchers found that while water, both sparkling and still, does a pretty good job of quickly hydrating the body, drinks with a little sugar, fat, or protein do an even better job of keeping us hydrated longer.
The reason has to do with the way our bodies respond to drinks, according to Ronald Maughan, a professor at St. Andrews Medical School and an author of the study.
One factor is the volume of a given drink: The more you drink, the faster the drink empties from your stomach and is absorbed into your bloodstream, where it can dilute your body’s fluids and hydrate you.

Milk is more hydrating than water.

The other factor that affects how much a drink hydrates relates to the nutrient composition of a drink. For example, milk was found to be even more hydrating than regular water because it contains the sugar lactose, some proteins, and some fats, all of which help delay the emptying of fluid from the stomach and maintain hydration for a longer period of time.
