Health Benefits of Kissing

1. Kissing can give your immune system a boost

More than 700 types of bacteria have been found in the human mouth, but no two people have the exact same makeup of oral germs, so exchanging saliva with someone can introduce new “foreign” bacteria into your body. A diverse microbiome can help regulate the immune system and protect against harmful germs.


2. Kissing can lower anxiety

From a chemical standpoint, one of the primary health benefits of kissing is its ability to release the hormone oxytocin (known as the love hormone), which induces a sense of calm, relaxation, and bonding in humans. Research has also shown that kissing reduces the chemical cortisol, which is associated with stress.


3. Kissing can help lower blood pressure

Our lips are made up of blood vessels, which become dilated during kissing. The blood is then directed toward the face and away from the rest of the body so the demand on the heart goes down, resulting in lower blood pressure.


4. Kissing can help delay signs of aging

Another reason to kiss as much as possible: The increased blood flow to your face can stimulate collagen production and contribute to anti-aging. It also stimulates the production of collagen and elastin, which is the substance “that beautiful skin is made of.”


5. It increases your sex drive

This one may seem obvious, but testosterone—the hormone responsible for sex drive in both women and men—is released into saliva during prolonged kissing. 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.
