Various studies show that Kissing is good

The kiss : pink apostrophe between the words I love you, it is no longer only considered a demonstration of affection and love to be exchanged between lovers, but recent studies show that the kiss is a real cure-all  against wrinkles, stress, and immune system problems . 
The World Kiss Day, celebrated on July 6th, precisely to help the whole world find the pleasure of kissing. According to research conducted in 2009 by researchers at the Lafayette College in the United States, it has been shown that after a kiss in both women and men, the level of cortisol , stress hormone, and oxytocin , the hormone of well-being and sociability, they had changed considerably, lowering the state of stress and increasing the sense of well-being and desire to be together. In fact, the kiss triggers a much stronger hormonal change in the human body than just holding hands while walking. Another study carried out in Japan has shown that the kiss lasting at least 30 minutes reduces the level of IgE, also known as the antibodies responsible for allergic reactions. During the kiss, the facial muscles are kept in training and the onset of wrinkles is reduced, without forgetting that with the increase in saliva, we protect our teeth. But did you know that kissing also burns 2 to 6 calories per minute? In short, the kiss is good and as shown by the various researches it is not just an urban legend. Remember, however, that kissing is also the fastest way to get in touch with the other person’s microbes, so pay attention to herpes, streptococcus and mononucleosis. 
We all kiss, but can we do it in the best way? Many people think they know how to kiss in a special way, but not everyone knows how important breathing is . Long kisses must be savored until the end so during the kiss the best way to breathe is through the nose, especially in the French kiss. Our hands are also very important and the way we move them during the kiss, we can gently caress the partner’s back or shoulders or pass them through his hair. The lips are the basis of every kiss, therefore they must always be taken care of but let’s not forget a perfect oral hygiene.
