Does Drinking Cold Water Burn Calories?

The answer to your question appears to be yes!

Read this:

"Studies have suggested that drinking water has a thermogenic effect in adults that significantly increases their resting energy expenditure (REE), the calories required to maintain normal body functions in a resting state. Water-induced thermogenesis hadn't been tested in pediatric patients, researchers said."

What's the Best Way to Stay Awake and Study?

Experts tell us that pulling "all nighters" rarely are effective in raising test grades. Newer research tells us that the best way to increase alertness is to drink a cup of coffee and then take a 15-20 minute nap. The nap clears the body of sleep inducing adenosine and gives just enough time for the caffeine to hit the blood stream.
