Introduction
Overnight watermelon juice should not be consumed. Watermelon juice is rich in sugar, which easily promotes bacterial growth and causes the juice to become sour and spoil. It has a very short shelf life—typically only a few hours. Even if refrigerated, the juice cannot avoid significant bacterial proliferation. Moreover, the taste of watermelon juice the next day deteriorates and may cause physical discomfort if consumed.

Watermelon juice is rich in sugar, which easily promotes bacterial growth and causes the juice to become sour and spoil. Its shelf life is very short—only a few hours. Even if stored in the refrigerator, significant bacterial growth cannot be prevented. Moreover, the flavor of the juice deteriorates significantly by the next day, resulting in poor taste and potentially causing physical discomfort. Therefore, overnight watermelon juice should not be drunk.

Watermelon juice is a beverage obtained by physically pressing watermelons. It has a refreshing and smooth texture and offers benefits such as relieving heat and promoting urination. As it contains no added preservatives, it is an ideal summer drink for beating the heat. Especially after physical labor, drinking an appropriate amount of watermelon juice can help quickly restore energy and relieve fatigue. Generally, watermelon juice can only be preserved for about 6 to 8 hours and should not be stored for long periods. It's best to consume it freshly squeezed to ensure freshness and avoid health issues caused by consuming spoiled juice.
