Many people, when the weather is hot, like to drink a large bowl of iced beer or iced beverages all at once. This "stimulating" way of cooling down can irritate the spleen and stomach, affect gastric juice secretion, reduce appetite, and cause gastrointestinal diseases such as indigestion, loss of appetite, abdominal bloating and pain, and diarrhea.
Although cold food can temporarily relieve the summer heat, after the mouth is stimulated by the cold, it can easily cause the salivary glands, the taste nerves of the tongue, and the periodontal nerves to cool down rapidly. Sometimes they can even go into a state of numbness, which can irritate the throat and cause adverse reactions such as pharyngitis or toothache.
Therefore, for the health of your stomach and mouth, no matter how hot it gets, don't gulp down your iced beer and drinks.
