Prevents Heat Stroke: Watermelon is effective in reducing both your body temperature and blood pressure. Many people in tropical regions eat this fruit every day in the afternoon during the summer to protect themselves from heat stroke. In India, you will find the fruit being sold by vendors in almost every street during the summer season. The high amount of water contained in watermelon also stimulates a release of excess liquid in the form of sweat, which cools your body further during hot summer days.
High Blood Pressure: The good amount of potassium and magnesium that is present in watermelons is very beneficial in terms of bringing down blood pressure. Potassium is considered a vasodilator, meaning that it releases the tension of blood vessels and arteries, thereby stimulating increased blood flow and reducing the stress on the cardiovascular system. The carotenoids present in these fruits also prevent hardening of artery walls and veins, thereby helping to reduce blood pressure and the chances of blood clots, strokes, heart attacks, and atherosclerosis.
