The prospect of cooties didn’t bother me in kindergarten once I pinned down my crush at recess and laid one on him (though i used to be a touch disappointed that he cried and stormed off toward the water fountain). Fortunately my kissing abilities and understanding of consent have both improved since then, and it seems that whether or not cooties are real, they may actually be good for your health. Seriously—making out has some very real, science-backed benefits that you just can examine below.
1. Kissing is nice for your teeth—as long because the two of you're fairly hygienic
According to Sivan Finkel, a cosmetic dentist in the big apple City, kissing results in increased saliva production, which helps our teeth rid themselves of harmful bacteria. “The extra saliva helps remineralize teeth and protect them from acid attacks,” he says.
Even better, some experts believe that saliva's mineral ions can promote the repair of small lesions in tooth enamel—but again, oral hygiene is vital. “Before you swap [spit], check their breath, and if they pass the sniff test, then kiss away,” Dr. Finkel says.
2. Kissing can give your system a lift
More than 700 forms of bacteria are found within the human mouth, but no two people have the precise same makeup of oral germs, so exchanging saliva with someone can introduce new “foreign” bacteria into your body, which isn't a foul thing.
“Trillions of microorganisms go on or inside us, and collectively they're referred to as the microbiome,” says Shilpa Ravella, M.D., a gastroenterologist and an prof of drugs at Columbia center. Dr. Ravella points to a recent Dutch study that found that after we kiss for quite 10 seconds, about 80 million bacteria are transferred between us and our partner, which might introduce new and sometimes helpful bacteria into our mouths. “Many studies have shown that having a range of bacterial species correlates with physiological state. a various microbiome can help regulate the system and protect against harmful germs.”
We’ll take that over a recall dose any day.
3. Kissing can lower anxiety
From a chemical standpoint, one in every of the first health benefits of kissing is its ability to release the hormone oxytocin (known because the love hormone), per Stephanie Hartselle, M.D., an professor of psychiatry at Brown University, who cites its ability to induce a way of calm, relaxation, and bonding in humans. The hormone, which is additionally released during foreplay and orgasm, “has been shown to be as powerful as meditation and plenty of antianxiety medications in producing a sense of peace and contentment,” Dr. Hartselle says.
Research has also shown that kissing reduces the chemical cortisol, which is related to stress.
4. Kissing can help lessen hypersensitivity
Bet you never knew making out could help ease itchy symptoms that include nasal or skin allergies.
Stay with us on this one: In 2006 allergist Hajime Kimata studied 24 patients with two varieties of allergies—mild atopic dermatitis (a skin allergy) and mild rhinitis (a nasal allergy)—before and after that they had kissed lovers or spouses for half-hour while being attentive to soft music.
"Usually, once you have an allergy, your body overreacts by producing IgE, an antibody to a selected allergen," says Srini Pillay, M.D., a Harvard psychiatrist. "But in these groups, after kissing, this antibody was decreased, thereby decreasing the aversion and symptoms."
5. Kissing can help lower pressure
According to Ryan Neinstein, M.D., a surgeon in ny City, our lips are made of blood vessels, which become dilated during kissing. “The blood is then directed toward the face and faraway from the remainder of the body," he says, "so the demand on the center goes down, leading to lower vital sign."
Also, remember that fact about cortisol? When your cortisol level is lower, so is your pressure. "The more you kiss, the more your heart races, and also the more your blood flows, ultimately reducing high vital sign,” Dr. Neinstein says.
6. Kissing can help delay signs of aging
Another reason to kiss the maximum amount as possible: The increased blood flow to your face can stimulate collagen production and contribute to antiaging. "The higher blood flow increases the quantity of small blood vessels helping to nourish the machinery of the skin,” Dr. Neinstein says. It also stimulates the assembly of collagen and elastin, which is that the substance “that beautiful skin is created of.”
“In order to maneuver your lips, your whole face must get entangled, which increases elasticity," Dr. Neinstein says. "Have you seen face yoga or facercises? There are yogis, estheticians, and dermatologists training women to try to to exercises for his or her face to stimulate collagen and lessen the requirement for a face-lift. Passionate kissing can cause firming the face, especially its bottom half.”
7. Kissing is reasonably sort of a treadmill—for your face
While a “simple” kiss burns only a calorie or two, tongue kissing uses all the muscles in your face and may use up to 26 calories per minute.
“There are 43 muscles in your face and eight in your tongue,” Dr. Hartselle says. “Kissing increases the blood supply to those areas by dilation of the vessels, and it’s possible that the muscle workout, combined with the facial flushing, in extended kissing sessions allows your facial muscles to be healthier and revitalized.”
8. It increases your drive
This one could seem obvious, but Rachel Abrams, M.D., an integrative health expert and author, points out that testosterone—the hormone liable for drive in both women and men—is released into saliva during prolonged kissing.
“In a study, males were more likely than females to initiate open-mouth kissing and kissing with tongue contact, and male saliva contains measurable amounts of the steroid hormone testosterone, which might affect libido,” Dr. Abrams says. “Testosterone is additionally an antidepressant, and it helps with mental focus.”
Another fun fact: Women who kiss other women also exchange testosterone, since we’ve got it too. So whether your partner is male or female, you're sharing hormones and pheromones.
