Does drinking milk help prevent dehydration?

Drinking milk can help prevent dehydration, but it is not as effective as drinking water. Milk contains water, but it also contains other substances, such as fat, protein, and lactose, which can slow the absorption of water into the body. In addition, milk can sometimes have a diuretic effect, which means that it can cause the body to lose water. Therefore, while milk can help prevent dehydration, it is not the best choice for rehydration. Water is the best choice for rehydration because it is quickly absorbed by the body and does not contain any substances that can interfere with its absorption.
