About kissing
People live in truth and freedom for beauty. Who can embrace the world more openly, who loves the world more, who is the best; Who is the freest and who is the best will have the greatest beauty in them.
The peak of kissing is in May and August 10.
The average kissing time in a person's life is two weeks.
But at different times and occasions, the desire for kissing is different. According to a survey conducted by the American Society for Sexual Behavior Research, people will increase the number of kisses regardless of gender, age and sunny weather, and May and August are the absolute peaks of kissing. So 520 is just the right month for kissing!
The benefits of kissing
First, it helps to lose weight.
Want to lose weight but don't like sports? Try kissing. A gentle kiss only needs to exercise 2 muscles in the face, which will consume 5 calories; But passionate kissing requires 34 muscles to work together and can consume 30 calories at a time. In contrast, walking for a minute will only consume 4-5 calories. Scientific research shows that under normal circumstances, each kiss will consume at least 12 calories. You can lose weight by kissing for 20 seconds three times a day.
I can't believe how thin I am.
Second, the exchange of bacteria in saliva-to help you test whether your partner is suitable.
It is often said that women in love have zero IQ, while men in love are not much better. Two people who are carried away by love have lost the ability to judge whether the other person is really suitable for them. So, it's not bad to test it with kissing.
Kissing can make or break a marriage. One of the "behind the scenes" is bacteria! Because the taste of human tongue or saliva is influenced by bacteria. There are more than 700 kinds of bacteria living in our mouth. A study shows that there are 278 kinds of bacteria spread between two people when kissing (fortunately, 95% of them are harmless). A study conducted a quantitative experiment with yogurt and got an estimated result. Kissing for 10 second will lead to the "migration" of about 80 million oral bacteria, and the oral flora of couples who kiss more than 9 times a day will become similar.
Moreover, after kissing becomes a habit, if two people's oral bacteria also produce "love", it is even more inseparable from each other.
Third, beauty and beauty
When kissing, the lip muscles of 12 group and the tongue muscles of 17 group are tense, which can promote blood circulation and help prevent wrinkles. The beauty effect is better than going to a beauty salon!
1 oh, my god, it's beautiful again
Oh, God is handsome again.
Fourth, forget the troubles and relieve the pain.
Kissing can produce hormones equivalent to painkillers, and kissing can also produce antibiotics with anesthetic effect. Another study in France found that a substance called "opioid phenol" in human saliva has analgesic effect, which is similar to morphine and other narcotic painkillers, but its analgesic effect is six times that of morphine.
Five, prolong life
When kissing, microorganisms such as bacteria exchanged by partners will react, which can stimulate the human immune system to produce specific antibodies. This process is called "cross immunity". Therefore, people who kiss frequently live an average of five years longer than those who don't kiss often, and have fewer chances of getting stomach diseases and blood diseases.
Six, inhibit dental caries and periodontal disease
Seventh, a good tooth.
Because kissing inhibits the stress factors of the whole body, it can also neutralize the stress factors in oral saliva and change the oral environment, thus preventing the occurrence of dental caries and periodontal disease.
? Research?
In addition, more research shows that men who kiss their wives before going to work every day earn more than men who don't kiss. This may be an alternative expression of "home and everything" ~
