When couples kiss, why don't they feel disgusted by each other's saliva? It turns out that the body will change
Xiaojiu received a reader's backstage request for help:
My boyfriend and I are each other's first term. We have been dating for half a year, but in the past six months, whether we are in public or when we are alone, we only hold hands, hug waists, and at most kiss Kiss on the cheek.
Last week, I wanted to take it a step further and offered to kiss. But he seemed to be acting a bit reluctantly , at first he just touched his lips, and when I wanted to be more active, he actually avoided his face.
He immediately looked for 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 so unhygienic."
Isn't it common for couples to kiss? Or is he not "love" enough for me?
1. What happens to your body when you kiss?
Regardless of men and women, some reactions when kissing are common. When kissing, close your eyes and your body will undergo wonderful changes.
The adrenaline secreted in the body promotes the beating of the heart , the person's breathing rate becomes more and more rapid , the heart rate rises, and the muscle tension also increases.
At the same time, the body releases hormones such as endorphins that make people feel pleasure, stimulated dopamine, happy serotonin, and trustworthy oxytocin, which bring happiness. Boys may also have some unique reactions.
Kissing warms up the relationship between couples. From a health point of view, there are many benefits of kissing:
1. Protect teeth
Saliva is the secretion of the human oral cavity. It contains lysozyme, immunoglobulin and other substances, which can kill bacteria and protect the gums. When the human body is kissing, it will produce a lot of saliva, which indirectly protects the teeth.
2. Weight loss and 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, which will bring pleasure to the brain, help relieve tension, relax the mood, and play an effective role in decompression.
4. Improve immunity
During the kissing process, the microorganisms in front of the mouth will exchange with each other, which will awaken the body's immunity and improve the immune function.
2. When couples kiss, do they feel disgusted by each other's saliva?
Some people may think that there is nothing wrong with saliva in their mouths, but they always feel a little disgusting when exchanging. But why do most couples don't feel this way when they kiss?
In fact, saliva itself is not smelly , 99% of its composition is 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. The saliva is the freshest, and naturally there is no peculiar smell.
The protein in the saliva is difficult to come into 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 happy hormones secreted by the body will also make you feel less sick.
Of course, kissing is not as simple as exchanging saliva between the two parties.
A study published in "Microbiome" estimated that a kiss lasting 10 seconds can cause the "migration" of about 80 million oral bacteria .
Will the exchange of oral bacteria lead to the mutual transmission of diseases?
Yes, 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 party's mouth, and the plaque and metabolites they cause may cause inflammation and swelling of gum tissue.
When kissing, some bacteria or viruses may enter the blood through the wound in the mouth, follow the blood flow, and have an impact, such as hepatitis and Helicobacter pylori.
Couples sometimes like to "plant strawberries" in order to increase the fun. However, it is not recommended to kiss in these two places, so as not to expose health risks.
·neck
The carotid sinus is located on both sides of the neck, where the carotid pulse is 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 increased vagus nerve tension, momentarily inhibiting the heartbeat, and causing arrhythmia.
The carotid sinus is also called the "dead point of hot kiss". If one party sucks here during a hot kiss, it may cause tinnitus, dizziness, fainting, etc., and even lead to cardiac arrest in severe cases.
· Ear holes
Kissing the ear area hard can create negative pressure that can perforate the eardrum.
The tympanic membrane is deep in the external auditory canal. Perforation or rupture can cause middle ear infection, affect ear hearing, cause ear pain, tinnitus, etc.
4. How to complete a "high-quality" kiss?
In a 2020 paper on kissing quality in the Journal of Relationship Research, 691 adults were asked to describe their "best kiss" and "worst kiss."
It turned out that for the best kisses, descriptions were passion, love, anticipation or surprise ; for the worst kisses, descriptions included lack of passion, quality of the kiss and feeling forced.
A kiss that is not played well may leave regrets between lovers. How to improve the quality of a kiss? There are 3 points to note:
Head: Research shows that 77 percent of people turn to the right when kissing with their partner. When you turn your head to the left, you may bump into each other.
Hands: When kissing, don't touch your hands randomly, but put one hand behind the other's head and hold the other's cheek with the other, which will be more tender.
Close your eyes: Studies have shown that kissing with your eyes closed can give you a more stimulating experience. Closing your 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.
