Watermelon is undoubtedly one of our favorite fruits—especially when temperatures start to rise. Fresh, juicy, and naturally sweet, it delivers hydration, quick energy, and a satisfying crunch in every bite. Because it is composed of more than 90% water, watermelon is particularly refreshing during hot weather and can help support hydration when temperatures exceed 30°C.
Beyond its cooling effect, watermelon contains vitamins such as vitamin C and vitamin A, along with antioxidants like lycopene. It also has a mild diuretic effect, which may help the body eliminate excess fluids and reduce temporary water retention. Affordable, widely available, and easy to store whole for several days, watermelon is often considered one of summer’s healthiest treats.
However, despite its many benefits, watermelon is not entirely without risk. There are certain issues consumers should be aware of to avoid potential health problems.
When Watermelon May Be Unsafe
Although rare, some watermelons can pose safety concerns. One warning sign appears when you cut the fruit open and notice large internal cracks or hollow cavities in the flesh.
Many people assume this is harmless and continue eating it. In most cases, internal cracking is caused by uneven growth, pollination problems, or sudden changes in temperature during cultivation. However, in some discussions, cracks have been associated with the use of growth regulators.
One chemical that has raised concern is Forchlorfenuron, a plant growth accelerator sometimes used in agriculture to increase fruit size. It is sprayed on crops to stimulate cell division and promote faster growth.
