Children can eat watermelon during a cough: First of all, watermelon is a fruit rich in vitamin C, which can strengthen your child’s resistance and help him/her to fight off foreign viruses or bacteria. Most coughs are due to respiratory infections, which can be caused by viruses or bacteria. Eating more fruits rich in vitamin C can strengthen your child’s resistance and help the infection heal. Secondly, watermelon has a particularly high water content. Eating fruits with a high water content can replenish the water lost in the body and has the effect of moistening the airway, which can easily expel phlegm when it is moist, which is also good for promoting the recovery of the infection. Watermelon is cool and has a clearing and detoxifying effect, which is also helpful in reducing inflammation. It is also a diuretic, which helps the body expel excess toxins from the body and promotes the healing of the infection. So babies or children can eat more watermelon for treatment during coughing.
