Is watermelon cool or hot in nature?
Watermelon is considered a cooling fruit, but its effects can vary depending on individual physical conditions and the environment. A detailed analysis is as follows:

The cooling properties of watermelon can help alleviate symptoms such as dry mouth, thirst, and irritability caused by hot weather or excessive internal heat ("heatiness"). Rich in water and vitamins, watermelon helps replenish bodily fluids, promote heat dissipation, and reduce body temperature, making it especially suitable for consumption in high-temperature environments to help the body regain a comfortable state.
However, excessive consumption of watermelon by individuals with a cold body constitution or weak digestion may lead to diarrhea, abdominal pain, or indigestion. Additionally, eating watermelon during cold seasons or in air-conditioned environments may intensify internal coldness, negatively affect health, and potentially trigger other discomforts.
It is recommended to consume no more than 500 grams daily. Those with weak spleen and stomach functions can consume it together with ginger slices or warm water to mitigate its cooling effects, and avoid eating large amounts before meals to prevent interference with nutrient absorption during regular meals.
