Chinese medicine considers children to be pure Yang bodies, with vigorous growth and development and vigorous vitality. For this reason, during the onset of the disease, yang energy develops and is prone to heat illnesses, and yin and fluid are easily injured, making them prone to the manifestation of internal heat. The common symptoms of internal heat in babies are mainly focused on body heat and heat accumulation in the stomach and intestines. Such as bad breath, hot breath, hot hands and feet, hot to the touch but normal body temperature, good irritability, sweating, dry stools, yellow urine, red tongue, yellow or thick greasy tongue coating, dry lips and other symptoms. Since the manifestations vary, they need to be targeted and regulated. Gastrointestinal heat accumulation: It is recommended to have a light and easy-to-digest diet, maintain a certain level of hunger appropriately, drink more water, give digestive foods such as hawthorn, add dietary fiber, avoid picky eating, ensure normal bowel movements and empty the stool as much as possible. No obvious symptoms of body heat: pay attention to a light diet, drink more warm water, and increase fruits and vegetables appropriately. Do not eat spicy, fried and other stimulating foods. Children’s bodies are delicate and have limited ability to regulate their bodies, and diseases are prone to change and are likely to develop rapidly into hyperthermia, so you should pay attention to your child’s performance and seek medical attention when you find abnormalities, and do not use medication at will to avoid covering up or delaying the condition.
