When couples kiss, why don't they find each other's saliva disgusting? The body will change
Xiaojiu received help from readers backstage:
My boyfriend and I are each other's first term. We have been dating for half a year, but for half a year, whether in public or when we are alone, we can only hold hands, hug the waist, and kiss the most. Kiss on the cheek.
Last week, I wanted to go a step further and offered to kiss. But he seemed a little reluctant , just touching his lips at first, and when I wanted to be more proactive, he turned his face away.
He immediately found a tissue and asked me if I wanted to wipe the saliva. He said, "There are a lot of bacteria in the saliva, and it feels unsanitary."
Isn't kissing very common between couples? Or is he not "loving" enough for me?
1. What happens to your body when you kiss?
Some reactions to kissing are common to both men and women. When kissing, close your eyes and your body will change wonderfully.
The adrenaline secreted by the body promotes the beating of the heart , the breathing rate becomes faster and faster , the heart rate rises, and the muscle tension also increases.
At the same time, the body releases endorphins that make people feel pleasure, stimulated dopamine, happy serotonin, trusted oxytocin and other hormones, which bring happiness, and boys may have some unique reactions.
Kissing warms up the emotions between couples. From a health point of view, there are many benefits of kissing:
1. Protect your teeth
Saliva is the secretion of human oral cavity, which contains lysozyme bacteria, immunoglobulin and other substances, which can play a role in sterilizing and protecting the gums. When the human body kisses, a large amount of saliva is produced, which indirectly protects the teeth.
2. Weight loss beauty
Studies have found that when kissing, the facial muscles are in a state of tension, which can help exercise the facial muscles and make the skin firmer. At the same time, kissing can also consume 12 calories of energy, promote blood circulation, and have a certain effect on weight loss.
When kissing, people will release adrenaline, bring pleasure to the brain, help relieve tension, relax, and play an effective decompression role.
4. Improve immunity
During the kissing process, the microorganisms in front of the mouth will exchange with each other, wake up the immune system, and improve the immune function.
2. When couples kiss, do they feel disgusted by each other's saliva?
Some people may think that saliva is nothing in their mouths, but they always feel a little disgusting when they exchange them. But why don't most couples feel this way when they kiss?
In fact, saliva itself is not stinky . 99% of its ingredients are water, and the rest may contain a little protein, calcium, sugar, etc., so fresh and pure saliva is basically colorless and has a little sweetness .
When men and women kiss, the mouth will secrete a lot of saliva due to stimulation. These saliva are the freshest and naturally have no peculiar smell.
The protein in the saliva is difficult to contact with the air , and will not be oxidized and decomposed into sulfide due to the evaporation of the saliva, so it will not become smelly.
In addition, the happiness hormone secreted by the body will also make you feel less nauseated.
Of course, kissing is not just as simple as exchanging saliva.
A study published in "Microbiology" estimated that a kiss lasting 10 seconds can cause about 80 million "migration" of oral bacteria .
Will the exchange of oral bacteria lead to mutual infection of diseases?
There are pros and cons to kissing. In the process of bacterial exchange, some pathogenic bacteria that can cause bad breath may also transition into the other's mouth, and the resulting plaque and metabolites may cause inflammation and swelling of the gum tissue.
When kissing, some bacteria or viruses may enter the blood through the wound in the mouth, and follow the blood flow to have an impact, such as hepatitis and Helicobacter pylori.
Couples sometimes love to "plant strawberries" in order to increase their interest. But these two places are not recommended to kiss, so as not to kiss health risks.
·neck
The carotid sinuses are located on both sides of the neck, at the pulsation of the carotid artery parallel to the upper edge of the Adam's apple, where the blood vessels are densely distributed. When the carotid sinus is compressed, it can lead to an increase in vagal tone, which instantly inhibits the heartbeat and makes the heart arrhythmia.
The carotid sinus is also called "the dead point of the hot kiss". If one side kisses here, it is likely to cause tinnitus, dizziness, syncope, etc., and even lead to cardiac arrest in severe cases.
·Ear hole
Kissing the ear area forcefully can create negative pressure and cause the eardrum to perforate.
The tympanic membrane is deep in the external auditory canal. Perforation or rupture can cause infection in the middle ear, affecting hearing in the ear, causing ear pain and tinnitus.
Fourth, how to complete a "high quality" kiss?
In a 2020 paper in the Journal of Relationship Research examining kissing quality, 691 adults were surveyed to describe their "best kisses" and "worst kisses."
It found that the best kisses were described as passion, love, anticipation or surprise ; the worst kisses included lack of passion, kiss quality, and feeling forced.
If the kiss is not played well, there may be regrets between the couples. How to improve the quality of a kiss? There are 3 points to note:
Head: Research shows that 77% of people turn to the right when kissing their partner. When you turn your head to the left, you may collide with the opponent.
Hands: When kissing, do not touch your hands, but place one hand behind the other's head and hold the other's cheek with the other, which will be more tender.
Eyes closed: Studies have shown that kissing with closed eyes results in a more stimulating experience, and closing our eyes allows our brains to focus more on tactile stimuli.
Kissing, if you practice a lot, you can bring a better experience to each other. Of course, you should also pay attention to your oral health.
