Introduction: When we usually take a nap or fall asleep because we are too sleepy, we basically wake up and see a pile of saliva, if we go close to smell, we will feel that the saliva is very smelly. If people can usually insist on brushing their teeth, they will find that the mouth does not stink, but the saliva that flows out is very smelly, why is this?
In fact, we first look at the composition of saliva, saliva is mainly composed of digestive enzymes and water and other substances, of which digestive enzymes account for only 2%, while the proportion of water reaches 98%. Normally, water and digestive enzymes do not produce a foul smell, so saliva should be odorless. But the reason why the saliva will smell in reality is because the saliva will come into contact with the air after it flows out, at this time, the digestive enzyme is that the microorganisms present in the air will gradually decay after contact, and eventually produce sulfides with a foul smell.
In addition, if we do not have the habit of brushing our teeth in our lives, or usually prefer to eat a variety of heavy food, it is also easy to make the mouth smelly. After the saliva flows out, the odor will be more serious because it will come into contact with food residues in the mouth. There are also some oral diseases, which can actually lead to the growth of bacteria, which can also cause bad breath problems.
First of all, from the kissing point of view, the general couple in the kissing, the mouth is close together, which also makes the air unable to enter it, when the saliva and air do not contact, naturally will not produce a smell with microorganisms. So in general, the saliva during kissing does not stink. However, some couples do not close the seam when kissing, so why is there no taste?
1. Dopamine effect
Dopamine secreted by the human body is a hormone that makes the human body happy, when the partner is kissing, the body will gradually secrete dopamine, because the amount of secretion is huge, which also makes the partner in a physical and mentally pleasant environment. When happiness gradually accompanies both parties, the problem of natural drool odor does not need to be too concerned, after all, what is important, many partners understand.
2. Adrenaline effect
When the partner is kissing, the adrenaline in the body also increases rapidly, and after stimulating the accelerated flow of blood, the excitement is also generated. Therefore, all kinds of heart rates that occur during kissing, such as rapid heart rate and blood vein swelling, are related to adrenaline, and the problem of drool odor will also be covered up.
3. Loss of sanity
In fact, in life, we often hear various statements about love, including people in love who have zero IQ, although this statement uses exaggerated techniques, but it also more significantly describes the real situation of people in love. When the partner kisses, it is also in the love period, when the cortisol produced by the kiss will gradually decline, and the partner will also "lose his sanity" in this short time, and the insignificant problem of natural drool odor will be ignored.
Although many people are less focused on other issues when kissing and will only focus on what they want to do, if one of the two parties has a respiratory or oral disease, it can easily cause transmission. Therefore, although kissing can be pleasurable, it must also be premised on health.
Conclusion: In fact, many times in life we will clearly distinguish the existence of pros and cons, some things are indeed easy to be covered up by another thing, such as forgetting physical pain when overly busy. Although accidental neglect can indeed make us achieve certain things, it is also easy to cause adverse consequences, so we still need to correctly understand and treat the bits and pieces of life in life.
