During your lifetime, you will produce enough saliva to fill two swimming pools.


Is it possible that the saliva in our mouth can fill two big swimming pools? Yes, it is possible if you know the precise indicators.

An average human body produces almost 1.0 to 2.0 litres of saliva in a day. At night the salivary glands are inactive and produce very little or no saliva. It means approximately 288 to 576 litres of saliva per year. If a person lives for 80 years, then he produces a maximum of 57600 litres in the lifetime. This amount is more than enough to fill two swimming pools.

Many of us only knew that the primary purpose of saliva is to predigest the food we eat. Besides that it also acts as a natural painkiller for the body as it is composed of a variety of constituents like water, electrolytes, mucus, antibacterial compounds, enzymes, proline, etc. The amount produced in the body depends on various factors like health, fitness, lifestyle, and age. It not only contributes to the digestion function but also maintains oral hygiene and stimulates a sense of taste.

It’s production is accelerated by the sympathetic nervous system and the parasympathetic. The saliva produced by sympathetic innervation is thicker, and saliva made by parasympathetic is watery. The sympathetic stimulus is to enable breathing, whereas parasympathetic stimulus is to simplify digestion. Saliva can also help to heal wounds in many species.

Three major salivary glands produce saliva, which are found in different part of the mouth. These are the parotid glands (placed in your cheeks), the submandibular glands (situated at the bottom of your lower jawline, and the sublingual glands (found on your tongue). Saliva made by these glands also helps to protect gums against any infection and tooth from decomposing. People producing less tend to have health problems.

It is not something you perhaps will spend much time thinking about. But knowing the actualities related to saliva has made me keep a watch on my health.
