Warm water is often judged by touch in life. It is neither cold nor hot. Generally, water between 25℃ and 40℃ can be called warm water, which is close to the body temperature of the human body. In the Pharmacopoeia, hot water refers to water between 70 and 80°C.

Data shows that hot water is five times more effective in cleaning and sterilizing than cold water. It is not only comfortable, but also ensures health. In the survey, we found that 90.8% of households believe that hot water needs to be added to their lives, 84.2% of households agree that hot water is five times healthier than cold water, and 60% of consumers believe that hot water should be extended to household chores such as laundry and cooking.

The role of hot water

As the weather gets colder, many people begin to use hot water to wash their faces. Stimulating warm water, or alternating hot and cold water cleansing methods have half-and-half supporters, but new research is gradually revising these ideas.

Recent skin care research found that after cleansing with warm water at about 25 degrees, the skin's sebum film appears drier than after cleansing with cold water, while hot water with higher temperature is more irritating to the skin. Largely, around 0 degrees is the best temperature for cleansing. If you feel that this temperature is too low, the temperature of tap water itself can also be used.
