Hello, I'm an expert in the field of nutrition and hydration. When it comes to drinking milk when dehydrated, it's important to consider the electrolyte balance and the body's ability to absorb fluids.

Milk is a good source of hydration in general, but it's not the best choice when you're dehydrated. This is because milk is relatively high in fat and protein, which can slow down the absorption of water by the body. Additionally, milk contains lactose, which can cause diarrhea in some individuals, further exacerbating dehydration.

The best approach when you're dehydrated is to drink water or oral rehydration solutions that contain electrolytes like sodium and potassium, which help to restore the body's fluid balance.

So, while you can technically drink milk when dehydrated, it's not the most effective way to hydrate and could potentially make the situation worse.

Unsurprisingly, all three milk-based drinks contained greater levels of sodium compared to the sports drink, which is one of the main reasons why milk was more effective in rehydration.read more >>
