If the child’s stomach is not sensitive, occasionally eating cold drinks, there is no obvious harm to the child; but long-term large amounts of cold drinks may lead to indigestion, dental caries, weight gain and other adverse consequences. Cold beverages generally refer to drinks that have been refrigerated and are usually high in sugar and low in temperature. If a child does not have a sensitive stomach and intestines, occasional consumption of cold drinks is generally not harmful. However, for some children with fragile gastrointestinal tracts, especially those who have long been adapted to ingesting warm water and hot food, the prolonged intake of large quantities of cold drinks can easily cause gastrointestinal spasms such as nausea, vomiting and abdominal pain, which can easily lead to discomfort. At the same time, due to the high sugar content in cold drinks, it is easy to ferment in the mouth, producing acidic substances that decalcify the teeth, thus triggering dental caries. Long-term consumption of large quantities of cold drinks with high sugar content may also cause weight gain, leading to obesity in children, which in turn increases the risk of chronic diseases such as hypertension, hyperlipidemia and diabetes mellitus. Therefore, it is generally recommended to drink less cold drinks in favor of good health.
