The stomach efficiently warms and adjusts food temperature, meaning cold food typically does not damage the stomach lining. However, sudden temperature shifts can trigger stomach contractions. This may cause cramps, bloating, or nausea in some individuals, particularly when eating quickly or on an empty stomach.

These reactions occur more frequently in children and individuals with chronic digestive conditions such as stomach ulcers or reflux, due to their sensitive stomach lining. For those with irritable bowel syndrome (IBS), consuming cold foods can intensify intestinal spasms and abdominal pain. Additionally, when the body is fatigued, cold, or recovering from strenuous exercise, digestive blood flow temporarily decreases, making cold drinks or food a potential cause of diarrhea.

Excessively hot food is also detrimental to digestion. Temperatures exceeding 65°C can cause micro-burns and inflammation in the mouth, throat, and esophageal linings. Moreover, hot food strongly irritates sensitive linings, increasing acid secretion and causing discomfort for individuals with stomach ulcers or chronic digestive conditions. Some may experience epigastric burning, fullness, or heartburn after consuming very hot dishes.

Both hot and cold foods can elicit varying digestive responses, depending on individual physiology. To protect digestive health, opt for warm, moderately-temperatured dishes, ideally between 15-50°C. This range aids easy digestion and minimizes uncomfortable reactions, avoiding extremes of hot or cold.

Eat slowly and chew thoroughly to prevent spasms, bloating, and reflux. Limit overly spicy and greasy foods, particularly when combined with hot or cold items, as this irritates the stomach lining. Individuals experiencing unusual symptoms after eating or drinking should consult a doctor to assess their stomach condition.
