Men who drank 3-4 glasses of water per day were 35% less likely to have a fatal heart attack during a 6-year follow-up compared to men who drank less than 2 glasses per day according to The Adventist Health Study.

The reason for this may be that drinking more water reduces blood viscosity according to the paper.

Men who drank 5 or more glasses of fluids other than water per day were roughly 1.5 times more likely to have a fatal heart attack during the 6-year follow-up.

Drinking roughly 8 ounces of cold water increased resting energy expenditure by 25% over baseline for more than 40 minutes in children who were approximately 10-years-old according to a study from Israel.

"It was previously demonstrated that drinking water significantly elevates the resting energy expenditure (REE) in adults, and that low water intake is associated with obesity and lesser success in weight reduction," the researchers noted.

"Consuming the recommended daily amount of water for children could result in an energy expenditure equivalent to an additional weight loss of about 1.2 kg per year [2.6 pounds per year]," the researchers concluded. Read the entire article | Email this article
