Can I have a drink of water?

In fact, saliva is a kind of human endocrine fluid, which is mainly composed of saliva and other secretions. Saliva, secreted by salivary glands, contains water, electrolyte, protein and other components, and is a liquid used to digest food. So, in theory, saliva is drinkable.

However, saliva contains bacteria, viruses and other microorganisms in the mouth, and direct drinking may cause infection and disease. In addition, saliva may also contain pollutants such as drug residues and food residues, which will also have a negative impact on human health.

Therefore, it is generally not recommended to drink saliva directly. If you need to drink water, you'd better choose clean and safe drinking water to ensure your health.
