1. It gently protects the stomach and intestines and reduces irritation.
Warm water (35-45 ℃) can avoid the sudden stimulation of ice water / cold water on the mucous membrane of the stomach and intestines.Especially for the elderly, children, or people with sensitive stomachs, drinking hot water can help maintain the rhythm of intestinal peristalsis and reduce the possibility of bloating and diarrhea - for example, before drinking warm milk, babies drink a few sips of hot water to warm their stomachs, and adults can drink hot water after meals to alleviate the feeling of indigestion.

2. Helps with metabolism and warmth, suitable for daily situations
Hot water can promote blood circulation in the body and help the body lose heat faster (for example, drinking hot water to sweat when you have a cold at the beginning), and can also warm up quickly in autumn and winter or during menstruation (for example, drinking red sugar water by your partner during menstruation to relieve abdominal discomfort). For people with a slower metabolism, warm water can indirectly help the body metabolize waste, and is more easily absorbed by the body than cold water.

3. Reduce the risk of bacteria, more suitable for the health of the whole family.
Boiled water can kill pathogenic bacteria (such as E. coli and parasitic eggs) in the water, and drinking it directly is safer - especially when making baby food or drinking water for the whole family, drinking boiled water can reduce the probability of "disease from the mouth", and it is more reassuring than drinking raw water or water that has not been boiled thoroughly.

4. Traditional habits + physical perception, more likely to produce a sense of comfort.
People who drink hot water for a long time will form a "warmth = comfort" body memory, such as drinking a cup of warm water to wake up the stomach and intestines in the morning, drinking a cup to warm up and help sleep before going to bed, this kind of gentle body feeling is more in line with the daily soothing needs of the family.
