Health Benefits of Watermelon
The top 6 health benefits of watermelon are highlighted below.
1. Keeps you hydrated
Watermelon is approximately 92 percent water and contains plenty of electrolytes, so it will help keep you hydrated in hot weather.
2. Reduces inflammation
The choline and lycopene in watermelon act as powerful antioxidants to reduce inflammation in the body.
3. Improves digestion
The fiber in watermelon will help aid digestion, maintain a healthy digestive tract, and reduce constipation issues.
4. Maintains healthy hair and skin
The vitamin A contained in watermelon facilitates the growth of collagen and elastin. As a result, it will help improve skin elasticity, maintain hair moisture, and oxidate hair follicles.
5. Reduces muscle soreness
Watermelon juice has been shown to improve athletic performance and reduce muscle tension. What’s more, it has positive effects on heart rate and circulation if consumed before a workout.
6. May lower the risk of heart disease
Since watermelon improves circulation and cellular function, it could potentially reduce the early risk of developing heart problems. Watermelon has been shown to reduce blood pressure and prevent fat accumulation in arteries. All of these factors are very beneficial for heart health.
