I am not finding the answer of this question in my text for my Nutrition Class(Dehydration Assignment)...

Can anyone help me answer this?

Here is the question..
What effects can alhohol and caffein have on hydration levels in the body?

Both act as diuretics and cause the body to dehydrate. That's why, when there are heat advisories, people are advised to avoid alcohol and high-caffeine drinks (coffee, sodas, etc.). Apparently, tea doesn't have nearly the amount of caffeine in it that coffee and colas do.

Be sure to read several articles in those search results.
