There is a saying in China that misfortune comes from the mouth, but I think disease enters from the mouth. All the bacteria and viruses in our body enter our body through the drinks we usually eat and drink, which leads to various diseases. And our life is inseparable from water. Adults contain about 60% water, and if the water content is reduced to 20% of the original body weight, people will not be able to survive. To maintain life, people need to take in about 2 liters of water from food every day. Learning to drink water scientifically can help us live a healthy and long life.

The most frequently consumed water has become the main carrier of bacteria. So, in what ways does daily drinking water bring in bacteria? Or what are the potential health and safety hazards? The following are some drinking water knowledge points:

1. Unsuitable drinking water pH.

Daily drinking water contains various ions and trace elements, and the acidity and alkalinity of water are determined by these ions and trace elements. PH value is the standard for testing acidity and alkalinity. When the PH value of water is less than 7, it is acidic water, and PH is greater than 7 is alkaline water. Usually, pure water is generally weakly acidic. Long-term drinking of weakly acidic water will cause the body to lack various mineral ions, while weakly alkaline water can not only supplement the body's essential minerals but also decompose large amounts of fish and meat, promoting digestion and absorption. Therefore, it is recommended that friends who drink pure water from pure water machines for a long time should supplement minerals in other ways.

 2. Unsuitable water hardness

The hardness of water is determined by the metal ions in the water, such as calcium and magnesium. Water with a higher metal ion content is hard water, and water without metal ions is softer water. So, is soft water better or hard water better? Water that is too hard or too soft is not good. Drinking high-hardness water often can easily cause kidney stones, while drinking soft water often requires supplementing the body with calcium and magnesium. Usually, the most suitable water hardness for drinking is 8-18 degrees (10 milligrams of metal ions per liter of water is 1 degree), which is slightly hard water.

3. Unsuitable water temperature

This is especially prominent in summer, because the weather is hot, everyone likes to drink ice water, but ice water has a very stimulating effect on the stomach and is extremely unfavorable to the stomach. Too hot water is also not suitable for drinking. The most suitable water for us to drink is warm boiled water, and the stomach absorbs warm boiled water twice as much as ice water.
