Spraying saliva while yawning

If you yawn, you are tired or hungry for food! When yawning, the mouth is opened wide, with the tongue raised. Due to the action of muscles, the tension around glands in the floor of the mouth, jaw and neck increases, causing a lot of saliva to be released. If the mouth is left uncovered, it can lead to saliva spraying. What does saliva spraying while yawning mean and why is it wise to cover the mouth while yawning?

Spraying saliva

  • Being tired and yawning
  • An unfortunate moment
  • Production of saliva
  • Elevated position of tongue and spraying saliva
  • What to do?

Being tired and yawning

After a lot of effort or after a long day, people become tired and may yawn. Yawning is a sign that we are tired. The body wants to get more rest, which increases drowsiness. To this end, less orexin is gradually released, so that the person becomes increasingly sleepy. When yawning, a fluid may be released, which sometimes squirts out of the mouth. It often happens to the person before they realize it. Why must one always cover the mouth when yawning and what causes saliva spraying?

An unfortunate moment

Yawning can just happen. Think about having a yawn before lunch or before coffee. In other words, it can also apply during work or during a nice meeting. If saliva is then sprayed, it can happen at a very unfortunate time. The liquid can end up at work, on the keyboard, in coffee or even on sandwiches. In some cases it can also be sprayed into someone else’s face. To avoid these painful, unsavory moments, everyone is taught from an early age to cover their mouth when yawning.

Production of saliva

There are salivary glands in various places in the mouth. Their exits are located next to the rear upper teeth and under the tongue. The floor of the mouth is the soft lower part of the mouth and consists of tissues and muscles. Part of this is the submandibular salivary gland and the sublingual gland. The submandibular salivary gland opens behind the lower front teeth. These are recognizable as two adjacent small elevations from which liquid is regularly secreted. The ends of the sublingual gland end behind these two elevations in a posteriorly running line. In other words, there is a V-shape on the floor of the mouth, where saliva is added to the mouth. With the tongue you can feel those V-shaped exits on the floor of the mouth.

Elevated position of tongue and spraying saliva

If one yawns, the mouth opens wide. This causes the tongue to be in a raised position, causing the floor of the mouth to be completely open. To achieve this, muscles in the neck, jaw and floor of the mouth are activated. In other words, the muscles around the glands under the jawline and under the tongue are temporarily tightened. This causes it to be squeezed shut for a moment, causing juices that have already been created to be drained more quickly. One gets an equal amount of secretion from the salivary glands, which moistens the mouth. If one does not cover one’s mouth while yawning, saliva may spray or squirt.

What to do?

Little can be done about spraying. It is a normal physical response to muscle strain during yawning. One must learn to always cover the mouth with one’s hand so that any saliva released is contained. It is certainly something that should be taught to the child at an early age, so that undesirable events are avoided. Please note that covering your mouth with your hand is also important when sneezing and sneezing, because it prevents the spread of bacteria.
