Why watermelon juice is great for staying hydrated and energized in scorching heat; check these 6 reasons

Watermelon juice is one of the best options for you this summer season if you are looking to beat the heat and stay hydrated and active amid high temperatures. Not only nutritious, but watermelon juice also comes packed with electrolytes, magnesium, and potassium, which can help in fluid maintenance and exercise performance.

Key benefits of watermelon juice include:

1. Keeps you hydrated


Watermelon is a fruit that contains more than 90% water, keeping your water intake in check. Whether you eat watermelon or sip its juice, it helps keep you hydrated. “One cup of diced watermelon contains 139 milliliters of water,” Alexandra Rosenstock, RD, CDN, a registered dietitian at Weill Cornell Medicine and NewYork-Presbyterian, told Verywell. This is one of the reasons watermelon juice can be refreshing after spending time outside on a hot day.

“Given its water content, watermelon can help replenish fluids if you are feeling mildly dehydrated after spending time in the sun, particularly if consumed with a salty snack,” Rosenstock said.

2. Watermelon offers electrolytes

Watermelon juice is perhaps the best source of electrolytes, including magnesium and potassium. “Electrolytes are lost in sweat; therefore, when exercising or sweating in the heat, replenishing electrolytes is helpful,” Julia Zumpano, RDN, LD, a dietitian at Cleveland Clinic’s Digestive Disease Institute of Nutrition, told Verywell.

Electrolytes are essential and play a role in many bodily processes. Magnesium helps your muscles and brain function normally, and potassium, which is found in all body tissues, helps your cells function normally.

3. Watermelon provides essential nutrients

Watermelon juice contains several nutrients the human body requires in everyday life. Those nutrients add up and make up a balanced, well-rounded diet. “Watermelon juice contains vitamin A, vitamin C, lutein, folate,” and more, Rosenstock said.

4. Lowers your blood pressure

Watermelon also contains L-citrulline, an amino acid. “Watermelon contains citrulline, which has been shown to aid in blood pressure control,” Zumpano said. L-citrulline has also been connected to rising bioavailability of nitric oxide, according to research. If your body makes less nitric oxide, you may have a higher risk of high blood pressure, atherosclerosis, insulin resistance, type 2 diabetes, and other cardiovascular diseases.

5. It May Have Other Heart Health Benefits

L-arginine is another amino acid found in watermelon juice. “L-arginine has been associated with certain health benefits, including improving blood flow and possibly reducing blood pressure,” Rosenstock said, as quoted by Very Well Health. According to the research, L-arginine can be beneficial to people with high blood pressure, elevated cholesterol, heart disease, insulin resistance, and diabetes. Watermelon juice is also rich in antioxidants like lycopene and beta‑carotene, and it provides vitamin C too.

Antioxidants promote cardiovascular health, and they can prevent or slow down some types of cell damage.6 “Lycopene has been shown to help improve blood lipids and blood pressure,” Zumpano further stated.

6. It Can Help With Weight Loss

Watermelon juice may be helpful for sore muscles, and research suggests watermelon might also help some people keep their weight under control.
