In general, watermelon can be consumed during menstruation, but it should be eaten in moderation.

During menstruation, mild dehydration or electrolyte imbalance, such as loss of potassium and magnesium, may occur due to blood loss and hormonal fluctuations. Watermelon, which is rich in water and potassium, can quickly replenish fluids and electrolytes, helping to alleviate discomforts such as fatigue and dizziness during menstruation. With low calories and containing dietary fiber, watermelon can also relieve constipation caused by slowed gastrointestinal motility due to hormonal changes, while avoiding high-sugar fruits like lychee and longan that may cause blood sugar fluctuations.

During menstruation, a woman's body is relatively sensitive and prone to various discomforts such as abdominal pain and backache. At this time, consuming large amounts of cold-natured fruits like watermelon may intensify the feeling of coldness in the body, hinder the discharge of menstrual blood, and even trigger or worsen dysmenorrhea.

However, it's important to consume it in moderation. Watermelon is cold in nature, and excessive consumption may cause abdominal discomfort, especially for those with a cold constitution or those who are prone to diarrhea. Additionally, if an individual has a cold constitution or already experiences dysmenorrhea, it is advisable to avoid eating watermelon during menstruation to prevent worsening of discomfort.
