Professionals point out that warm water of 35℃ ~ 40℃ can best protect the stomach and intestines, and it is also the most comfortable temperature for the gastrointestinal tract.

As for the baby milk that mothers are most concerned about, how many degrees of water should be used for brewing? Experts say that it is best to mix milk powder with water at 45 ~ 50℃, because some studies have pointed out that mixing infant milk powder with warm water at about 45℃ has the purest fragrance and can make the milk even. If the water temperature is too cold or too hot, it may not come out, or a small amount of milk powder may agglomerate. In addition, because there are many heat-sensitive nutrients in infant milk powder, including vitamin C, vitamin A, DHA, etc., the higher the water temperature, the easier it is to be destroyed. Therefore, after the milk powder is soaked in warm water at 50℃, the temperature can be reduced to about 37℃, which is suitable for feeding the baby directly.
I'm tired of drinking boiled water. Would you like to add some honey occasionally for a change?

It is suggested to brew honey with warm water below 55℃, which can not only melt honey, but also retain its nutrition.
A study on the elderly found that if the elderly insist on drinking tea every day, the risk of dying of cardiovascular disease is reduced by 82% compared with those who don't drink tea.
