Would you buy a drink that promised to increase your alertness and promote a bit of weight loss? What if I said you could get it for free, then would you give it a try?
It's not one of those fancy elixirs made of exotic juices, an over-priced energy drink or even a vitamin-touting beverage.
It's plain, good-old-fashioned water
Researchers at Vanderbilt University Medical Center led by Dr. David Robertson
have shown that ordinary water does more than just quench thirst. It has some other unexpected physiological effects: it increases the activity of the sympathetic (fight or flight) nervous system, which raises alertness, blood pressure
and helps to burn calories.
You may be thinking, "But I don't want to increase my blood pressure," (unless you have very low blood pressure to begin with). Not to worry: The researchers found that water did not significantly raise blood pressure in healthy young subjects.
However, it does promote weight loss. How much exactly?
Robertson calculated that it might be as much as five pounds a year if a person drank three 16-ounce glasses of water a day and nothing else changed.
"This is not going to be the answer to the weight problem in the United States
," he said in a statement. "But it's interesting that activation of the sympathetic system is enough to do that."
