watermelon health benefits

In addition to its sweet taste and refreshing effects, watermelon offers a variety of health benefits with its rich nutrient content. So it is safe to say that watermelon is as beneficial as it is delicious.

It is estimated that the watermelon first appeared in West Africa some 5,000 years ago. Then spread to other parts of the world.

Currently, the biggest watermelon producers are; respectively China, Turkey, Iran, and Brazil. Since watermelon is produced in different parts of the world at different seasons, it is possible to find the fruit at the supermarket even in 4-season. 



As is evident from its name a watermelon is packed with water. Roughly, 90 per cent of watermelon is made of water which is what we need to stay hydrated on hot days of the summer. Especially, its pink flesh is pleasing to the eye as much as it is pleasing to the palate. 

It is good to remind ourselves that apart from water, watermelon contains many vital and necessary nutrients. Down, in the article, I will be touching upon the health benefits of eating watermelon thanks to the nutrients found in this super fruit.

Before carrying on, referring to the substances that watermelon contains will consolidate the claimed health benefits of the watermelon mentioned below.


Nutrition Facts 

Watermelon is one of the lowest in calories and low in sodium among fruits and contains a high amount of vitamin C and vitamin A. Furthermore, vitamins B1B5 and B6 are also present in watermelon but in small quantities. 

Potassium ( 5 %) and magnesium ( 4%) (154 grams) are found in small quantities just like Vitamin B. 

Another important factor is watermelon is a fat-free fruit ( sometimes considered a vegetable ). And, it is poor in protein

Essentially what makes watermelon that healthy is largely related to its amino acid and antioxidant content

Lycopene ( antioxidant ) that gives pink colour to the flesh of watermelon is suggested to have an anti-cancer effect. Lycopene is also available in tomatoes, grapefruit, and red oranges. Citrulline ( amino acid ) is rather high in watermelon. 

Remember these substances, both of them promise many health benefits.

Potential Health Benefits Of Watermelon 


1-) Hydration

First things first, the reason its name contains “water ” is not in vain. As indicated at the beginning of the article, roughly 90 per cent of watermelon is made of water. Watermelon consumption, especially on the hot summer days, helps us stay hydrated

Sometimes you can replace it with watermelon juice to indulge yourself. No doubt it is refreshing and packed with vitamins—minerals. 


2-) Linked to Reduced Risk of Cancer

The leading role, in this case, belongs to Lycopene which is an antioxidant found substantially in watermelon. As mentioned above, it is also found in tomatoes, grapefruit and red oranges. 

According to scientific research; lycopene is effective in terms of preventing cancer. The same study is highlighting the fact that this antioxidant ( Lycopene ) can help the human body fight against free radicals that can damage the cells thus causing cancer. It is not an exact solution but it is, indeed, a promising factor whilst avoiding cancer. 

 It is suggested that lycopene may lower especially the risk of prostate and uterine cancer 


3- ) Heart Health

Given the fact that cardiovascular diseases are the world’s number one killers, seeking out the best ways to protect heart health is quite logical. Diet, genetics, and lifestyle factors including exercise are determinant factors for reducing the risk of cardiovascular diseases. Surprisingly, watermelon too may prevent us from developing heart diseases thanks to, once again, lycopene found in watermelon in high quantities.

Lycopene also provides protection for cells and normal tissues in the body by keeping arteries clean and flexible against plaque formation.

What is more, according to scientific research; lycopene may regulate cholesterol levels and reduce blood pressure. What we should know is high cholesterol and blood pressure can trigger a heart attack. 


4- ) Skin

Likewise many fruits and vegetables, watermelon may contribute to skin health. First of all, it is related to the amount of water watermelon contains. When we consume watermelon, the rich water content protects the moisture balance of the skin thus protecting the skin health.

Not only the amount of water but also the high vitamin content of watermelon could herald healthy skin. Especially, a high amount of vitamin C supports collagen production that reduces wrinkles by increasing blood flow to the skin.


5-) Muscle Recovery 

This time another substance in watermelon is the hero. Citrulline ( amino acid ) which abounds in watermelon has been proven to accelerate muscle recovery.

Especially watermelon juice is much better for athletes, who desire faster muscle recovery, than watermelon since the vitamin in the juice is easier to absorb. Citrulline (amino acid) is also suggested to increase blood flow.

Even though it hasn’t been fully proven, citrulline from watermelon might improve athletic performance.


6-) Better Digestion 

Watermelon, as we repeated many times, contains a high amount of water. Since water helps the digestive organs work efficiently, watermelon consumption helps digestion with its high water content. 

Additionally, watermelon has a handsome amount of vitamin C and a small amount of fibre both of which aid digestion. As such, consuming watermelon seems a good idea whilst dealing with constipation

However, too much of a good thing is bad. If a person consumes watermelon in large amounts it may set off some ailment, such as diarrhoea, bloating and gas. 


7-) Hair Growth

 Keratincollagen and once again citrulline. These mentioned substances may sound unfamiliar. However, what we should know is these substances have an important role in hair health. 

Vitamin C is needed for collagen production which plays a vital role in hair growth. By providing a high amount of vitamin C, watermelon promotes hair growth albeit indirectly. 

Citrulline, which we spoke of above, enables blood vessels — that carry the blood through the body — to work optimally. As long as blood vessels work efficiently on the scalp, the scalp can receive necessary substances for hair including keratin which is an indispensable protein, especially for hair growth. 

To sum up, citrulline aids the blood vessels to work at their best, thus, it supports hair growth.
