A female graduate student of a medical college in France even pointed out in her graduation thesis that a typical French kiss can make people swallow 250 bacteria at the same time. How many problems can a kiss cause? Besides consuming 12 calories, what are the chain reactions that affect health when kissing for just 45 seconds? & ltbr & gt 1, periodontal problem oral cavity is the place where human bacteria breed the most. Although most bacteria can't escape the disinfection of gastric acid, many bacteria that escape the net will still cause health doubts. & ltbr & gt When kissing passionately, the state of forgetting oneself often makes people lose their minds instantly. In this case, the most common thing is to accidentally bite and suck the other person's mouth. Xie pointed out that now it is not just exchanging saliva, but entering the realm of blood and water, especially when there is a wound in your mouth, it is easy to cause diseases such as periodontal disease and gum inflammation. Therefore, it is suggested that when there is a wound in the oral cavity, & ltbr & gt2 and the eardrum rupture, even if it is not close to the ear, when the kiss is too forgetful and too hot, it will also cause the pressure imbalance of the eardrum. Under the pressure of large and small, cracks appear and even the eardrum breaks. & ltbr & gt Although this traumatic eardrum rupture will cause people to lose hearing by about 20 to 30 decibels, they can recover by themselves after being treated by doctors. However, I still suggest that French kissing should restrain your emotions a little, don't cover each other's ears with your hands when kissing, and give them more breathing space. & ltbr & gt3. Is fatal allergy so exaggerated? It was just a kiss. Why do you have to go to the emergency room next moment? That's because the other person ate the ingredients you are allergic to beforehand. & ltbr & gt Because when you eat, there will be some food scraps in your mouth. If the mouth is not cleaned, these residues must be completely decomposed after more than 8 hours. Therefore, if you finish eating, you'd better brush your teeth or rinse your mouth before kissing, or kiss your cheek instead. Experts even suggest that if you feel difficult to breathe or feel unwell during or after kissing, it is best to see a doctor as soon as possible, even if you have never had such a situation before. & ltbr & gt4, gastrointestinal ulcers should not be thought to be too excited and nervous, so the stomach began to ache faintly, but actually it was all bacteria under the kiss. & ltbr & gt Due to the dirt attached to teeth, there are a large number of bacteria such as Helicobacter pylori and Helicobacter pylori. When these bacteria enter the body with saliva, they will secrete toxins, destroy the mucosal tissue of the stomach and lead to diseases. Although generally speaking, people with bacteria in tartar are mostly worried about their health, brush your teeth before kissing, rinse your mouth after kissing, and don't swallow a lot of saliva when kissing. & ltbr & gt5. Herpes virus inexplicably grows a painful and itchy blister on the corners of the mouth, and it gets longer and longer. Yes, it is kissing that makes you infected with herpes. & ltbr & gt Generally speaking, herpes simplex usually occurs in children with weak immunity. This blister and oral ulcer can be cured after a week of treatment, but in fact, these stubborn herpes viruses will still lurk in the body, waiting for your resistance to weaken and then attack again. & ltbr & gt Dr. Anna from the University of Washington in the United States said that if you find a small blister or ulcer wound on your partner's mouth, don't kiss him. Although the other person may still infect you with herpes virus after recovery, at least the amount of germs that can be transmitted is countless times less.
