Watermelon is cold, and excessive cold stimulation will weaken normal gastric peristalsis and affect gastric function. Therefore, people with spleen and stomach deficiency, indigestion and gastrointestinal discomfort should eat less or not eat watermelon. Patients with heart failure or nephritis should not eat more watermelons, so as not to increase the burden on the heart and kidneys and make the condition worse. Patients with oral ulcers and early colds should not eat more watermelons.

If you have a cold for a month, your voice is hoarse. Drink more water, eat more oranges or peaches, and supplement vitamin C.

Try to eat less. If the cold lasts for a long time, go to the hospital and prescribe some medicine.
