A feeling of dryness. Because when people are nervous, the body will be in the so-called "emergency state".

state", at this time the human nervous system will have a certain instinctive reaction. According to research, this reaction is present throughout the animal kingdom. For example, when a person or animal is from a pursuer.

When escaping there, the mech selectively activates the gods that are most useful for escaping.

meridians, while temporarily inhibiting other relatively minor nerves. Obviously, people.

When you feel embarrassed in front of a large public, eating is the least important, so this.

The nerves leading to the mouth that control the production of saliva by the salivary glands will be inhibited first. There is a shortage of people.

Lack of saliva will of course make your mouth feel dry. In addition, people often return in case of emergency.

Pupils dilate, rapid heartbeat and other phenomena may occur to meet the emergency situation.

The physiological needs of the most essential organs.

If you do something, you must not do something", and the physiological functions of the human body need to be comprehensive.

Weigh. In the event of danger, the human body will turn off all unnecessary functions, including:

The salivary glands are part of the digestive system. Before you are a lion.

Chasing and chasing, I only hate that when my legs are short, I am afraid that digesting the food just now is better than running away.

Fate is much more secondary. Some people feel nauseous and want to put their stomach in the event of an emergency.

It's the same with spitting out food.

Why do people feel a dry throat when they are nervous?

It is true that when people are speaking or doing other activities in full view, they often have a feeling of dry mouth. Because the body will be in the so-called "emergency state" when people are nervous, at this time the human nervous system will have a certain instinctive reaction. According to research, this reaction is present throughout the animal kingdom.

For example, when a person or animal is from a pursuer.

When escaping there, the body selectively activates those nerves that are most useful for escaping while temporarily suppressing others, which are less important. Obviously, eating is the least important when a person is embarrassed in front of a large public, so the nerves leading to the mouth that control the saliva production of the salivary glands will be the first to be suppressed. People who lack saliva will of course feel dry mouth.

In addition, people often have dilated pupils and rapid heartbeat during emergencies to meet the physiological needs of the most necessary organs to cope with emergencies.

If you do something, you must not do something", and the physiological functions of the human body need to be comprehensively balanced. In the event of danger, the body shuts down all unnecessary functions, including the digestive system, of which the salivary glands are part. When you are being chased by a lion and only hate short legs, it is probably more important to digest the food you just ate than to run for your life.

Some people feel nauseous during an emergency, and the same is true for wanting to vomit food out of their stomach.

When we feel nervous, what happens to our body that makes our throats dry? For example, when you are speaking in public, you feel nervous, and your body enters a state of "whether to fight or run", and then your mouth will become dry. This is because your autonomic nervous system is activated.

This phenomenon can be seen throughout the animal kingdom and is actually an evolved trait that helps animals to take immediate action when they are in danger, such as fleeing predators as quickly as possible. Which autonomic nerves are activated, it has to do with the importance of the event to which the animal has to respond. For example, in the above example of a predator threat, eating is naturally irrelevant at the moment, and the most important thing is to escape.

As a result, the nerves leading to the mouth that control the secretion of salivary glands are inhibited, causing the mouth to dry out. At the same time, when you're nervous, your pupils widen and the blood vessels leading to your muscles and heart dilate in order to send more blood to the most important organs that must act on stress. This phenomenon is related to a "fight or flight" reaction.

In a stressful or dangerous state, your body will shut down all unnecessary functions, including the digestive system. Your salivary glands are part of your digestive system. If the next prey a lion is you, you certainly don't have to continue digesting the food in your stomach.

At this time, you may also feel nauseous and want to vomit, which is also the reason.
