Watermelon Nutrients Reduce Aortic Blood Pressure In Hypertensive People

More people die of heart attacks in cold weather because cold temperatures cause blood pressure to rise, forcing the heart to work harder to pump blood into the aorta. Researchers at Florida State University who conducted a 12-week study with 13 hypertensive middle-aged obese men and women found that consuming a watermelon extract daily reduced aortic blood pressure both at rest and while their hands were immersed in cold water. Participants took four grams of the amino acid L-citrulline and two grams of L-arginine per day, both from watermelon extract.
